The Globe world type is a new world type that changes how biomes and structures are generated.

World Size

You can customize this world type just as you can customize a superflat world. You are able to select the size, which is the length and width of the world; You can choose 1,000 blocks wide or anything greater. Instead of the normal world border, each edge of the world ends with ocean, with the "border" being extremely dense fog.

At least one of every biome* and structure will generate in this world.

* By this I mean general biomes; there will always be a jungle biome, but not necessarily a jungle edge biome.

Biome Generation

With this world type enabled, biomes are generated in a specific order based on their temperatures. The hottest biomes are always at the middle (between north edge and south edge) of the world, and the coldest biomes are always at the northernmost and southernmost parts rows of the world. The biomes that generate in between, while abiding by temperature rules, are still pretty random like in vanilla.

Expanding the World

When you click the world and select "edit" there is a new option: expand. Clicking this will allow you to enter a new size that is greater than the original size. After doing this, the world edges will be expanded the next time you play.

Conclusion

With this new world type, you have the option of having finite worlds, which allow you to have easier access to every structure and biome (i.e. you don't have to travel 10,000 blocks to one, unless you make the world that large) and a more predictable order of biomes.

If you haven't read Part 1 or Part 2, I really recommend you do. In a nutshell, Part 1 makes oceans larger and adds a sailboat, and Part 2 adds a lot of ocean animals and plants. Anyway, let's dive straight into this suggestion.

Ships

Structures

Technical Stuff

Conclusion

Many features have been added to Minecraft over the years. Some small, some large; some game-changing, some useless. While features of all shapes and sizes can improve the game, I think features that give the player more options and more things to play around with can improve Minecraft in ways smaller features just can't. At the end of the day, which would make the game better: a new dungeon, or a new tool to play around with?

It is because of this and other reasons that I believe player-built ships would be a wonderful addition to Minecraft. I hope that I have proposed a balanced and reasonable method of implementing this, and I hope that you enjoyed reading.

Changes

Cannons are now much more balanced. (Suggested by MinecraftPROFESSIONAL123.)

Pirates can now go on other ships.

Merchant Ships now have a few cannons for self-defense. (Suggested by steam66.)

Pirate Coves now have a chance of being tent-filled. (Suggested by steam66.)

First added in Snapshot 15w41a, elytra allowed the player to glide. This was really cool. It made people come up with neat new minigames, it made people create elytra courses in their worlds, and it would even save people from fall damage in exchange for no chestplate. There was something people did, though, that made elytra basically wings, instead of gliders. They would shoot themselves with a Punch II Enchanted Bow and it would give them a huge boost. This was quite difficult to do, but people still did it.

Then came Snapshot 16w50a. I was hoping so badly that Mojang would fix the bow-boosting exploit, as it broke the whole transportation system. What did they do? They made it so that you could get an even bigger boost using fireworks. And this time without taking any damage.

This breaks transportation completely. People argue, "Oh, well, it's end game so it doesn't–" No! This is Minecraft. There might be a final boss, there might a dimension called, "The End," but there is by no means an end game. People still play a lot after they get elytra. In fact, on a lot of servers, people spend the first few days trying to get to this end game. Look at Hermitcraft, for example. So don't give me this end game nonsense.

What's the point of using any other form of transportation when elytra + starless firework rockets are the most efficient form of transportation? I would have loved it if they have made lava and fire give off steam that would boost you vertically with elytra, like in this Minigame. Why? Because if you wanted to transport a long distance and you hadn't already placed in a ton of lava pools, other forms of transportation would still have a use!

Well, those are my thoughts. I know, I need to calm down a bit. And yes, I know a lot of people are probably going to hate me because of this. For some reason, people seem to love becoming a god in survival mode. I don't get it, but whatever. Maybe I'm the odd one. I don't know. I would like to hear your thoughts.

I love this idea! If cave biomes were added, there could be special music for each biome.

I was originally a bit sad that the Nether's theme was expanded beyond the purely magma/hellish theme, but I think I've come around to the new biomes.

What I am disappointed about, though, is that the Nether star has not been given new uses and that beacons are still a lackluster item.

I'm a bit surprised Mojang didn't expand or overhaul brewing as well; with all of the new types of fungus, it would have been the perfect time. Finally, I don't like the Netherite tier and I dislike the niche use of the smithing table. It seems odd that a villager who never interacts with Netherite requires such a workbench.

Overall, I like this update. It's not perfect, but I think it's done a good job at making the Nether more full of life and fun to explore.

Quote from C1ff»

One idea I've just thought of is the ability for the Party Members to receive commands through the chat system. You would address them by saying their name with a comma, followed by a command. The command and member name would be case insensitive and would ignore punctuation, and there would be a few such commands, most of which would just display information such as the member's location. (This could also serve as a more immersive way to switch between "stay-here" and "follow" modes)

If something like this were implemented, it would be best for the names of the characters and the commands to be in colors other than white (a la commands) in order to distinguish them from regular text chat.

The Update Aquatic was one of the best updates in Minecraft’s recent history— it addressed a serious issue (a lack of ocean content) and, for the most part, executed its additions well. In fact, before the Update Aquatic, many people (including me) made suggestions for the ocean. However, the ocean could still use more content and some of the Update Aquatic needs tweaking, so I’d like to propose some more changes and additions to the ocean.

Continents

The Sea Floor

Beaches

Ocean Mobs

Deep Sea Mobs

Transportation

One final thing that needs to be improved in oceans is transportation. Tiny boats only fit two players, can’t carry chests, break too easily, and are a little slow.

Longboats

The longboat is crafted with two normal boats. It can hold up to three players and a chest. Up to two players are able to row; if one player is rowing, then the boat goes the same speed as the normal boat, but if two players are rowing, it goes much faster. Unlike the normal boat, a single hit from a tool or arrow will not destroy it. Instead, it has more health and takes multiple hits to be destroyed.

Sailboats

The sailboat is crafted with a longboat and a banner. The banner design will be shown on the sail. Like the longboat, the sailboat can hold up to three people and is able to hold a chest. However, the sailboat does not move by oars; instead, the sailboat moves without a player having to hold W.

One of the advantages of the sailboat is that you don't have to hold down W. It will keep moving until you press S to stop it, so you're able to look at treasure maps, organize items in your inventory or the chest, or even try to shoot arrows at mobs or players with your bow.

The sailboat goes forward at a speed that starts out at 0.75 times the speed of the normal boat, but slowly increases to a speed that is 1.5 times that of the normal boat. It takes 10 seconds for this speed increase to complete. This means normal boats and longboats are more practical for transportation across short distances, while sailboats are more practical for traveling across long distances.

The sailboat is turned by pressing A and D. The first player to enter the sailboat is the one able to turn the boat.

Like the longboat, the sailboat takes multiple hits (even from an arrow or tool) to be destroyed.

Conclusion
With all of these new features, I hope Minecraft would have oceans that are more fun and interactive. The new animals and monsters would make oceans and beaches more challenging and interesting. The new boats would make navigating across oceans a lot more enjoyable and efficient since they are faster and can have chests.

Thanks for reading! What do you think about these ideas?

Hello everyone!

Almost two years ago I made a post asking what you all thought the best "Golden Age" Minecraft version was. However, I assumed that the "Golden Age" consisted of versions of Minecraft after Beta 1.7 but before Official Release 1.7 (i.e. Beta 1.8 through Official Release 1.6).

I chose this for multiple reasons. For one, it marked a defined aesthetic of Minecraft: Beta 1.8 introduced new terrain generation, along with many iconic biomes and structures, and it introduced the hunger bar, new food items (beef/steak, chicken, melons, and rotten flesh), new mobs such as endermen, and experience, all of which have become iconic aspects of Minecraft. The update helped prepare for Official Release 1.0, which added the Ender Dragon and marked an important point in the acceleration of Minecraft's growth.

Years later, Official Release 1.7 came out. Why did it mark the end of the "Golden Age"? The name of the update—"The Update that Changed the World"—reflects this concisely. While old biomes remained, many new common biomes were added, changing the overall look of Minecraft worlds. While a small change, the rose, one of two iconic flowers, was replaced by the poppy, and many new flowers were also added. Two new types of wood (dark oak and acacia) were also added. Overall, the look and feel of Minecraft, which had been very similar since Beta 1.8, changed after this update.

There was also a certain unmistakable quality of the community during this time. The community was much different, whether for better or worse. Many prominent YouTubers such as Stampylonghead became popular toward the end of this era. A period of immense growth for the game and many memories, this era was in my opinion the Golden Age of Minecraft.

Anyway, that's just my opinion. Of course, it's mainly based on nostalgia. Do you agree or disagree? Please let me know when you think the "Golden Age" of Minecraft was.

Have a nice day!

Chairs

I've seen a lot of chair suggestions with the same flaw– the chair serves no purpose. We have beds, but they allow you to skip the night and set your spawn. Some have suggested that chairs be used to skip the day, but others argue that removing the ability to simply sit down from the chair also takes away from its aesthetic use. So, I propose a mixed approach to solve those issues.

As you can see above, chairs would be able to be made out of wood, cobblestone, and wool. They link together when placed together (allowing you to make a couch), but this can be avoided by holding shift while placing them.

When you right-click on a chair, you sit in it. Just like there is a "leave bed" button that appears when you enter a bed, there is a button that says "skip to night." This button fades away after sitting in the chair for 5 seconds. Pressing the button will make the screen fade to dark, and then the game will skip to nighttime. Like with beds, every player on the server must be doing this to skip to night.

The chair does not contribute to the nights slept statistic like the bed since you are choosing to experience the dangers of the night. Also note that the chairs do not set or remove players' spawnpoints.

If you right-click a chair with a wool block, it will add cushioning. On the wooden and cobblestone chair, it looks like this:

But on the wool chair, it looks like this:

(If the chair had another chair adjacent to it only on one side, it would have the second model; otherwise, it'd have the first model.)

With this system, chairs would be customize-able, aesthetically pleasing, and useful for if you need to skip to night.

Fixing common problems

TODO

TheMasterCaver's World (TMCW) is essentially a "total conversion" / "alternate development path" mod reflecting my own vision of the game as it might have evolved since 1.6.4, the most recent version I've ever played on due to changes in later versions, which partly influenced the development of this mod (I never actually made it with the intent to be a "fork" of the game but simply a collection of features made to enhance my own enjoyment of the game, as well as the enjoyment of modding itself, which led to the addition of many "secondary" features).

This includes many of my own unique features in addition to my own ideas of how some newer features could have been implemented, such as 1.9's "attack cooldown", Mending, favoring mining instead of resource farms, and especially terrain generation, the original and still main focus of this mod, hence its name (suggested by ScottishMushroom).

There are also features which are directly based on newer versions, if not functionally identical, including biomes, blocks, mobs, and game mechanics; as well as features restored from previous versions or even never properly implemented, and features taken from suggestions made by others (both for this mod and vanilla itself). In total, there are more than 500 new blocks/items/biomes/entities, and as many as a thousand additions and changes in total.

Another major focus of this mod is optimizations and bugfixes, including bugs which still haven't been fixed, or at least reduced, in the latest vanilla version, and bugs introduced by the client-server merge in 1.3.1, which ended the "golden age" for many players due to previously multiplayer-only bugs and latency/desync issues in singleplayer. Despite the amount of content added the footprint of the game is no higher than, or even lower than, vanilla 1.6.4 (the usual recommendations for modded versions, e.g. allocate more memory, are irrelevant).

Note that I primarily made this mod, and mods in general, for my own use and this affects the development/update schedule of this mod (I've not made significant updates for several years at a time while playing on my first world/other worlds; major updates (version 1, 2, etc) reflect major changes to world generation/internal mechanics and are not guaranteed to be backwards-compatible with older worlds), as well as what features/suggestions I may implement.

Installation instructions for the official launcher (also included in a Readme in the download; note that other than the name of the installation "TMCW" must match the name of the json file in the download, e.g. TMCWv5):

1. Create a new installation named TMCW with 1.6.4 as the version and click Play to download 1.6.4 (if you don't already have it), then close the launcher.

2. Go to the versions folder in .minecraft (%appdata% on Windows) and copy the 1.6.4 folder and rename it and the jar inside to TMCW.

3. Replace 1.6.4.json with the TMCW.json file in the download.

4. Using a zip utility like 7Zip or WinRar, add the contents of the "Mod" folder to TMCW.jar and delete the META-INF folder (note that the contents of the "Mod" folder were merged into the jar, don't add the folder itself, or anything else in the download).

5. Open the launcher and edit the installation you made to choose TMCW from the versions list; select it and you should be able to launch the game; since TMCWv4.5 successful installation is easy to confirm since the title of the game window will be "TheMasterCaver's World (version #)", otherwise, the changes to world generation will be obvious (e.g. "-123775873255737467" in vanilla 1.6.4) and the player skin will be my own skin (1.6.4 used an old skin server which no longer works, requiring a resource pack to change).

6. If the game fails to launch you may have misspelled something (e.g. "Failed to download file ... Exists: Nonexistent") or added files incorrectly (e.g. "NoClassDefFoundError") or forgot the delete META-INF (e.g. "SHA-256 digest error for aab.class", or similar). Newer Java versions (e.g. Java 17) have not been tested but if vanilla 1.6.4 runs then so should TMCW, but it is usually recommended to use e.g. Java 8 to run older versions.), the default player skin is also my own skin.

I highly advise changing the game directory (you can simply add a folder name to the end of the default path without creating one; e.g. ".minecraft\TMCW", which will be automatically created when you launch the game), both to avoid issues with the game crashing due to loading invalid settings from options.txt (since TMCWv4.5 this is no longer an issue) and/or resetting them as well as loading a world in the wrong version (since TMCWv5 only worlds it created can be opened, and it also stores statistics files under a different name, but vanilla can still see/load worlds it created).

Also, if Optifine (only supported by TMCWv4 and earlier) is used it should be installed first by manually copying the contents of the Optifine jar to the Minecraft jar (same process as described for TMCW), not by using its installer (the order the files are added may not matter but I installed TMCW after Optifine). There are no other mods that TMCW is compatible / have been tested with, including other mods I've made, so don't try to mix them.

This is also a singleplayer-only mod; I have not written it to be compatible with multiplayer.

Version 5 update:

The product of years of development, TMCWv5 adds more new content than all previous versions combined, bringing the total number of features added by all versions to 325 blocks, 103 biomes, 45 entities/variants, 34 items, and 7 enchantments, in addition to dozens of new structures, trees, changes to game mechanics, and more (these include nonfunctional features present in vanilla such as giants, bark logs, and even 2x2 oak trees, and does not include variants of blocks that do not have an item form, such as plant variations in flower pots, only the addition of large flower pots). Note that due to the scale of the changes TMCWv5 cannot load worlds created in earlier versions; they will not even appear in the saves menu, only worlds it created (all other files are now completely separate from vanilla so the only issue with sharing game directories is loading a world created with TMCW in vanilla).

One of the biggest changes is a complete rewrite of world generation, which consequently generates completely different worlds from earlier versions and was a major reason for the delay in releasing TMCWv5; some of the core changes and new blocks were added in an intermediate update, TMCWv4.5. Cave generation in particular is much more varied with many new variations added, as well as increases to the size of the largest caves, which can exceed a million blocks in volume, 600000 for ravines and 1.7 million for a giant cave region (for comparison, in previous versions they could reach about 500000, 425000 and 1.3 million respectively), and large caves are significantly more common. Also, only the very largest caves are now excluded from generating near the origin; due to this the "NoExclusion" patch that previously disabled this exclusion has been dropped, partly also to ease maintenance:

This is one of the largest single caves that I have found, with a volume of nearly 1.1 million blocks, located at at 420, -956 in the seed "6511199847387183207" (it is at the bottom-center of the image above, with the small cave to its lower-left representative of a typical "large cave" in vanilla 1.6.4, with the largest known such cave having a volume of about 26,000 blocks):






The same seed also has an enormous ravine at -620, 112, and they can get much larger - up to 368 blocks long and 50 blocks wide. This also shows how underground biomes now extend all the way down to and even including bedrock, with ore and bedrock variants added to match the "biome stone" blocks (these are a stone-like block variant which has the same properties as stone, thus you need Haste II + Eff V to instantly mine "sandstone biome stone", as opposed to earlier versions where it was real sandstone/snow/ice/etc, but it was limited to the upper third of the underground, and only lined caves before TMCWv4):

Another significant change to world generation is that the area within about 1000 blocks of the origin is always entirely non-ocean biomes - it is highly unlikely that spawn will be in/next to an ocean or on a small island, and it will be within a relatively flat and open biome (plains, tropical swamp, meadow, mega tree plains, bushlands, or oasis) in the Default world type; Large Biomes may place biomes too far away to be detected, and also has different origin continent generation so oceans aren't so far away (due to this Large Biomes is not simply an upscaled version of Default until you get further from the origin). Land is also more common, making up about a third of the world, compared to about a fifth in vanilla (about 75% ocean, plus "rivers" along shorelines). Here is a large-scale land/ocean map:

Also, all world generation (caves, terrain, feature placement) now fully utilizes a 64 bit seed; previously, and in vanilla, only biome generation used all 64 bits with the result that any seed which differed by a multiple of 2^48 had the same non-biome dependent features, and even the biome generator itself had "shadow seeds" which reduced the number of unique biome maps to 2^63, but this was fixed. Text seeds also now use a 64 bit hash function instead of 32 bit (e.g. "TMCWv4" now hashes to "-4968953994433483799" instead of "-1816924181"), and the selection of a random seed enables any 64 bit seed to be chosen (it was previously based on Random, with 2^48 possible 64 bit values, some of which likely had the same lower 48 bits), and a random seed is now only used if the textbox is completely empty so you can directly enter 0 as a seed (there was no technical reason why this wasn't allowed):

"-123775873255737467" and "-556121437483305083" in vanilla 1.6.4, showing similar biome and river borders (these have the same lower 48 bits and should produce very different biome maps since the biome generator uses a 64 bit RNG, but due to a poor algorithm there are only 2^63 unique biome maps and many of those have many similarities when only higher-order bits change. TMCW previously used the same methods as vanilla):


The same two seeds in TMCWv5, which are entirely unique down to river and biome borders:


"-2143500864" and "-7379792618385405355" in vanilla 1.6.4 (these are "shadow seeds", which give the same biome map but different terrain and reduces the number of unique biome layouts to 2^63 since every seed is one of a pair):


The same two seeds in TMCWv5, which again produce completely different worlds:

There are also several new biomes added, as well as many minor biome variants to improve existing biomes (e.g. Ice Hills now has its own "river" variant which uses the same generation as its parent biome):

Tropical Ocean, which has coral reefs, which can also be found in small patches in all non-frozen ocean variants. Tropical Ocean generates alongside "hot" biomes as well as in large patches in open oceans, and the seafloor is entirely covered in sand, predominately quartz sand. Also shown is a Quartz Beach, which generate alongside "tropical" biomes like Jungle and Tropical Swamp, and has quartz sand and sandstone instead of regular/yellow sand and sandstone:


Frozen Ocean now generates as a proper biome, instead of in tiny patches around the edges of Ice Plains (most of the "frozen" water alongside them in older versions/vanilla are actually Frozen River); similar to Tropical Ocean it can be found alongside snowy biomes and in patches of open ocean; unlike other biomes they try to avoid generating right next to opposite extremes. As shown here they also have icebergs made out of packed ice and Polar Bears, one of three variants of bears. The seafloor is also entirely gravel:


Oceans also have Shipwrecks, which come in 3 different sizes with the largest having a chest hidden below the deck (all sizes are fairly common but the largest size with loot is much rarer than in 1.13+):


Quartz Desert, which includes a new structure, Quartz Desert Pyramids, which has a main pyramid and two smaller pyramids; the main pyramid contains a maze inside which leads to a treasure room at the top which has the same loot as desert/jungle temples. One of the most notable features is that the walls are made out of "Reinforced Quartz Sandstone", which takes an extremely long time to mine even with an Efficiency V amethyst pickaxe; however, once you reach the treasure room there is a button which when pressed will convert it into normal quartz sandstone. There are also mob spawners hidden under the walls in the maze which spawn skeletons and white husks. Also visible in the distance are Saguaro Cactus, a large branched form of cactus (like normal cacti breaking the base will cause the entire plant to break; however, instead of dropping itself it drops saplings; if Silk Touch is used (blocks must be broken from top-down for efficiency) they drop logs which work the same way as wood logs (Silk Touch is not required):


Mushroom Forest, which has uniquely blue-green foliage, even affecting the color of spruce leaves (the only biome that currently does so), and huge mushrooms in all colors:


Mesa Plateau Forest, which generates at the top of Mesa Plateau and provides a source of wood and passive mobs in an otherwise barren biome which only has rabbits:


Another feature of Mesa biomes is the addition of mineshafts that generate above sea level; these are in addition to normal mineshafts and are smaller with spruce wood supports and gold ore which generates as part of the structure (it can only be found in mineshafts). Unlike underground mineshafts they only generate sections that have at least one block without sky exposure above them (this is only applied to mesa mineshafts, and only in non-Superflat worlds, avoiding the bugs that 1.10's implementation brought). Another change made to mesas is the addition of a red variant of clay which replaces the normal gray clay that previously generated:


Mineshafts in general were improved by adding platforms below all pieces, not just corridors, and they can no longer intersect themselves vertically (the "floor" of a piece, where the wooden platforms are, is now included when checking for intersections), and the type of wood is based on the types of trees found in the most common biome around the central room/start (most treeless biomes default to oak with some having other types of wood):


Badlands; this is not a rename of Mesa but an entirely new biome which is a combination of Mesa with different colors and a red sand desert; below the surface stone is replaced with red sandstone with pockets of red clay and red sand:


Icelands, a frozen version of Mesa and Badlands made out of snow blocks and packed ice, including new opaque and blue ice variants, as well as "vegetation" made out of ice and scattered blocks of "dry ice" underground:


Uniquely, instead of having lava caves in Icelands, as well as Ice Hills and Ice Plains Spikes, contain water instead of lava, and no lava is allowed to generate within these biomes (it may flow into them; low-level lava/water is separated as shown here). Also visible are Glow Squid, which can be found in any body of water below the surface:


Big Birch Forest, which includes two new variants of birch trees, including a 2x2 form, both of which also occasionally generate in normal birch forests, much as big oak trees do:


Autumnal Forest, based on a suggestion, including many of the mobs; including Black Bears, which are smaller than other variants and always hostile and never naturally spawn as babies; Autumnal Creepers, which are similar to normal creepers but have rubies added as a rare drop, making it renewable; Vampires, which have a chance of inflicting Poison when attacking and if attacked may spawn bats at the player's location which will chase them until the vampire is killed; and a new structure, Pumpkin House, which appears as a large pumpkin and contains two witches, a black cat, and a chest with loot. There are also 4 new variants of "autumnal" trees and bushes with their own leaf and sapling blocks, thus can they be grown anywhere. Despite appearances this is not a "hot/dry" biome; my custom biome coloring system allows them to be separate from the color:




Villages can now generate in Savanna Plateau and use "compressed cobblestone" variants and all-bark logs; villages in general are also more common for a given area of spawn biomes (the spacing was reduced and up to 3 attempts are made if a village failed to generate; they are still confined to their spawn biomes to help avoid derpy villages), and additional torches were added to ensure that every building is lit and the smallest houses now have doors:


Roofed Forests now have Woodland Mansions; a large cubical structure similar in design to my bases which has many different rooms in various combinations inhabited by witches and cave spiders (the whole structure acts like a witch hut with cave spiders added to the spawn list). Similar to 1.11 they are fairly rare but nowhere near as much; this one was found at -688, -816 in the seed "6511199847387183207" and a sampling of 10 Roofed Forests had 2 mansions (the sheer number of biomes makes any one biome fairly rare; the grid size for mansions is only 14x14 chunks vs 80x80 in 1.11 but there is an 80% failure rate due to terrain that is too hilly):


Mushroom Islands are much more colorful with more colors of mushrooms and Mooshrooms to match - green, blue and purple in addition to red and brown (brown was added in a later vanilla version):




Last, but not least, the Nether has finally had new content added, after having been neglected until now (one reason is because I barely spend any time in it, mainly using it to collect quartz for XP and my main base, never returning afterwards); including new mobs, Nether Husks, Nethermites, naturally spawning Endermen, dungeons (nether husk, witch, normal skeleton, zombie pigman. Similar to Endermen dungeons in the Overworld zombie pigmen spawned form spawners are always hostile but will not alert other pigmen when attacked), red and brown huge mushrooms, veins and lakes of magma blocks, lava lakes (small lakes that appear anywhere as in the Overworld), veins of gravel and soul sand (gravel does not fall during world generation), Nether gold ore, and significantly more "normal" caves, including larger variants and ravines (the ratio of air:solid blocks was slightly reduced to offset the increase in caves, there are still large empty areas though. Caves also form a secondary "lava level" at y=4):

Here are some of the many mobs/mob/entity variants that were added, not including ones mentioned above, along with some notable changes to existing game mechanics:

Zombies now have a Husk variant, which comes in 4 different colors; yellow, red, while, and pink ("nether"), with Giants having all the same variants except for pink as they do not spawn in the Nether (the code does fully support it though). The color generally matches the biome they are found in; yellow = desert, red = mesa and badlands, white = volcanic wasteland and rocky mountains, pink = Nether) and they all have similar behavior as the ones added in 1.10 (the duration of Hunger is lower due to draining much faster but costs more hunger overall). Nether husks also spawn with golden equipment and drop gold ingots, nether brick item, and glowstone dust as rare drops; the Giant form drops its corresponding color of sand (1-2 and up to 5 when killed with Looting). Also, they can spawn anywhere within their respective biomes (including below sea level), as well as exclusively from husk spawners found in various structures:


Endermites and Nethermites were added; Endermites may spawn when an Enderman teleports after being attacked by a player while both variants are an uncommon natural spawn in the Overworld/End and Nether respectively (this represents the only change that TMCW has made to the End so far, besides just refactoring the world generation code).


Skeletons now have a baby variation with similar behavior to baby zombies (move faster and fit in 1 block high spaces), and a Stray variant was added which mainly spawns in snowy biomes and a few other biomes (as with Husks they spawn anywhere as 50% of skeletons). There is also a chance, based on difficulty, that a skeleton will spawn with a sword instead of bow:


Added rabbits, which come in 10 variants, including a new red variant and naturally spawning killer rabbits (using the original name/texture), and spawn in most biomes, most notably in biomes which previously had no passive mobs, such as deserts; they are also immune to fall damage and cactus as they otherwise tend to kill themselves too easily:


Added 8 new tamed cat variants; black cats also spawn in witch huts and pumpkin houses, and ocelots were added to the passive mob spawn list and these do not despawn (only one spawned as "hostile" mobs), making them easier to find, including on Peaceful difficulty:


Similar to husks there are yellow, red, and while silverfish variants, and silverfish now naturally spawn in any biome below sea level (naturally spawned silverfish cannot enter blocks unless they have been attacked by a player). There are also more variants of monster eggs, renamed to Infested (block) for mossy/cracked stone bricks, the 1.8 stone types, and red sandstone (red sandstone always spawns red silverfish while other types depend on the biome they are in):


Fish now spawn in oceans, lake biomes, rivers, and swamps, can can be caught with a water bucket, giving a Bucket of Fish which can then be placed as water/fish; the model is based on the cod model for 1.13 while the color is based on the 1.6.4 "fish" item, which was not changed:


Another notable change to mobs is that nametagged hostile mobs and tiny slimes will not despawn and turn passive on Peaceful (interestingly, according to the code tiny slimes are not supposed to despawn on Peaceful in vanilla):


Hostile mobs also now require a block light level of 5 or less to spawn (sky light is still 7 or less, and the failure rate is still level/8 so a block light level of 5 gives a 5/8 failure rate); this complements the minimum light level that cave maps will map (6 or more).

Items and XP orbs also now float in water:

Here are screenshots of all the new blocks and items, excluding "similar" variants (e.g. infested granite, which looks just like granite, or mushroom blocks other than caps):

New items/item models, as well as a new item frame rotation mechanic (beds at the top); many redundant items were eliminated by having blocks drop themselves (e.g. bed block vs bed item,, which used a different ID), which enabled custom 3D block models to be used instead of the generic "2D with thickness" item model:


These are all the plants that can be placed in flower pots, with additional models obtainable by right-clicking them while sneaking; the tree models are different at every coordinate for a virtually infinite number of possible forms (not shown - every color of huge mushroom model, which are all the same as the brown ones shown). Also visible in the lower-left is a large variant of flower pot, crafted with a U of bricks (including the lower corners), which may be more aesthetically pleasing for larger plants:


Glow Ink Sacs can be used to make glowing item frames, signs, and paintings (added later); signs have white text instead of black and only the text glows. These are also shown inside a cage of Obsidian Glass, which blocks light while letting you see through:


Stalagmites are one of the most complex and varied blocks that I've added with a total of 21 item forms/base variants (7 each of small/large/giant) and 168 total variations when including complete render-only forms (you can also individually mine the blocks from larger variants; the item that drops will depend on how many blocks were above/below the one that was mined as also indicated by the size of the selection box and breaking animation, which covers up to 3 blocks at once):


Stalagmites also make renewable lava possible; if you place a liquid source block above the block a stalagmite is on and if it drips the corresponding liquid (usually water but netherrack, and stone in volcanic wasteland, drip lava) it will gradually fill a cauldron:


There are also dozens of new variants of ores to match their corresponding biome-specific underground blocks (only gold has a netherrack variant); this also shows the variants of sandstone from the side as well as 12 new bookshelf variants, corresponding to 0-11 books which can be added/removed by right-clicking them (the original recipe crafts a "normal" bookshelf which cannot store/remove books, same for any naturally generated bookshelves):

Several new additions, Hammers, Smelting, Vein Miner, Luck Of the Sea/fishing non-fish items, and Dry Ice/ice generators, completely change or add fundamental new game mechanics, respectively allowing uncrafting, using Fortune on iron and gold and/or not needing a furnace to smelt them, mining multiple blocks at once (besides blocks like cactus which cause other blocks to lose support), and a new way to obtain various items:

Hammers function as a multipurpose mining tool (i.e. they can mine and harvest stone, wood, and many other blocks faster, even blocks like glass) and more signif8natly, an uncrafting tool - many blocks will drop some of the materials they were made with when mined instead of themselves, or turn into entirely different blocks, such as cobblestone, which turns into gravel, then gravel sand, then sand, making it renewable with some effort. Storage blocks, such as iron/coal/etc blocks, as well as quartz blocks, are converted with 100% efficiency, otherwise Fortune can increase the drop rate (Silk Touch does not work on hammers). Notably, when used on iron and gold ore they drop "raw" items which are affected by Fortune:

Also shown is the effect of "Smelting" a new enchantment which directly converts iron and gold ore into ingots, and enables the full effect of Fortune (hammers only apply half the effect, up to 1.6 items/block as opposed to 2.2; along with raw iron/gold blocks being crafted with 4 items this helps make Smelting much more desirable than easily obtained hammers).

Another new enchantment is Vein Miner, which allows you to mine up to 8 ore blocks at once (4 * level, with 2 levels) when applied to a pickaxe (completely mining most single ore veins other than coal/quartz), and up to 3 wood blocks above/below you when applied to an axe (ideal for carving a staircase up a 2x2 or 3x3 tree; only level 1 is needed):


Both Smelting and Vein Miner are classified as "true treasure" enchantments, meaning they can only be found in naturally generated chest loot (for comparison, Mending is only excluded from the enchantment table), and Vein Miner can only be found as a level 1 enchantment, except in "double dungeons", where both enchantments are most likely to be found (each is about 15 times more common than other enchantments in the first of 2-3 chests; double dungeons are about 1 in 16 dungeons, 1 in 5 in network cave regions), they are also about twice as likely in nether dungeons.

Also, fishing rods can now get Luck Of the Sea (via a book) and can catch items other than fish, even enchanted books (but not Smelting or Vein Miner), and the time between catches is shorter and less random (this was mainly added due to the addition of fish mobs, which otherwise makes fishing obsolete once you've found a river/lake/ocean). Note that Luck of the Sea is required to catch any treasure, and the area has to be "open" (similar to newer versions) as a strong nerf to AFK fishing farms (the way Mending works is also a major nerf as you can't automatically repair items; still, this would allow unenchanted fishing rods to be used if they could catch treasure by default).

Additional enchantments include Swift Sneak, functionally identical to the enchantment added in 1.19 (increases sneak speed by 15% per level, from 30% to 75% at level 3), and Long Fall, which allows you to fall one block further per level (up to 7 blocks at level 4) without taking damage, useful in situations where you frequently fall a bit too far (it is incompatible with Feature Falling but Protection is compatible and reduces fall damage), with both most commonly found in abandoned mineshafts (unlike Smelting and Vein Miner they can be obtained from the enchantment table and trading but at a reduced chance).

An interesting new block, Dry Ice, now allows you to make ice/packed ice generators in a similar manner to cobblestone generators; when water touches dry ice it will freeze and turn into ice (flowing water) or packed ice (water source); ice can be directly harvested while packed ice can be obtained by mining the ice with a non-Silk Touch tool, which will create a source block which then turns into packed ice (it may be easier to just craft packed ice from ice):


Notably, the idea for dry ice came from a suggestion which has unfortunately since been deleted and it was never properly archived; as in the sugguestion the main source is the surface is Ice Plains Spikes, where it generates in patches, along with single blocks in caves underground, including in Ice Hills and Icelands.

Other notable features include barrels, a cheaper, lag-free alternative to chests (I did previously improve the performance of chests but they are still rendered as entities), and composters, which give dirt instead of bonemeal and can compost more blocks and items than the 1.14 version.

Maps have also been completely reworked, including dozens of new colors, the ability to map the Nether, End, and most significantly, caves:

These are "cave maps", which will map areas with a light level of at least 6 within 8 blocks (taxicab distance and going around, not through, walls) of a player-placed torch (naturally generated torches do not count); this is similar to "MCMap", the mapping tool that I use to create renderings like this:


A surface map showing how different biomes have different colors (only general biome colors are used due to a limited palette); block variants, such as stained clay and wool, also have their own colors:


A map in the End, which was previously unmappable (they would show a grainy pattern). You can also see another feature of maps; while viewing a map your coordinates are displayed in the upper-left (this applies to surface maps as well, the screenshot above was taken before I added this):


Cave maps can be used to map the Nether (surface maps do not work); as mentioned above, this requires that you place torches regardless of visibility; this also shows how they work in more detail, notice the isolated diamond that corresponds to the torch at the top-center of the image:

Despite all of the content that has been added over the years TMCW remains incredibly lightweight; baseline memory usage is less than 30 MB (on a default Superflat world at 8 chunk render distance; the only thing a normal world changes is the amount of blocks loaded, depending on render distance every 16 block increase in depth (based on loaded sections, which is 1 for default Superflat) requires up to 21 MB of additional memory), and the size of the 1.6.4 jar plus TMCWv5 is smaller than vanilla 1.8 despite having far more content and a lot of redundant/dead code from unused vanilla classes:

A full list of all additions and changes can be found here (the download fo the mod includes this as well as lists of blocks, items, biomes, recipes, mechanics, etc):

Descriptions for earlier updates have been moved to the comment section to reduce the size of this post (it exceeded the character limit and had nearly 200 images), and reduce the amount of formatting that I need to fix every time I update it:

Version 4.5 update

Version 4 update

Version 3 update

Version 2 update

Version 1 update



MCMap for TMCWv5:

https://www.dropbox.com/s/azsqpp5trzwlbj2/mcmap-TMCWv5.zip

This is an adaptation of MCMap by WRIM, itself an adaptation of the original made by Zahl, both of which are unfortunately no longer readily available as Zahl's thread was deleted and WRIM's website expired (archived version of Zahl's thread with a link to WRIM's website; the link above is to WRIM's GitHub) which correctly renders most new blocks and block variants in TMCWv5 and contains bugfixes and improves its cave rendering mode, the one feature that makes it stand out from most map rendering tools (unlike most such tools it only renders caves that have been explored, specifically, if there are torches in/near them; this is much like how my cave maps work except walls are ignored, but by using a realistic range false positives are minimized):

A comparison of the same world rendered with Minutor and MCMap:

For comparison, this is how MCMap 2.4.3 renders the same world; it is possible to fix some of the colors with its colors.txt file but the majority of blocks in TMCWv5 are variants of existing blocks and what blocks have what variants is hardcoded into the program (for this reason I have not provided a colors.txt), and some blocks do not render at all:

Examples of the underground rendering mode, including an animation of what I explored over 10 days, showing how only explored caves (with torches) are rendered:

An example of the output window when underground mode is used; the original version prints out the location of every torch it finds (appears to be debug output that was left in), which I removed and replaced with the total number of torches found when finished. This and other changes help speed it up as well:

These are world generation mods which I originally made for myself with the main feature being modified cave and ravine generation. The double and triple height versions increase the height/depth of terrain relative to the average ground level, with double-height adding 64 more blocks and triple-height adding 128, without otherwise changing terrain generation; the highest mountains in triple-height come within a few blocks of the world height limit.

Triple-height in particular increases the size of caves and ravines (double-height and original to a lesser extent), and together with double-height also modifies abandoned mineshafts so they generate higher up; ore distribution was also changed to reflect the increase in ground depth and/or changes in lava flood level in caves. Note that strongholds still generate at their normal depths, which can be as low as around y=10, as do diamond and redstone ores (reduced by 5 layers in the original mod and 2 in double-height); other ores, like iron, generate proportional to the increase in terrain height; for example, from 0-63 to 0-127 and 0-191 respectively for iron. I also made a few tweaks such as removing void fog (very prevalent otherwise since caves go down to y=6, 5 layers lower than normal) and increasing cloud height (Optifine can otherwise do these as well; note that the cloud height option in Optifine adjusts cloud height based off the new heights I set it to).

Also, double-height terrain has two versions, one with very large cave systems and another without, while triple-height terrain does away with them altogether but makes more changes to cave/ravine generation, with a greater range in cave/ravine sizes.

Updated 2/21: Triple-height terrain now has its own world type when you install the mod, as shown below; note that if you update the mod, you have to change generatorName to triple_height or new chunks will generate like a default world:

To install this mod, first make sure that you have ran 1.6.4 at least once so its files are downloaded, then copy the ".minecraft\versions\1.6.4" folder and rename the copy and the jar file inside to "1.6.4_mods", and replace "1.6.4.json" with the custom json provided above (the same file can be used with any mod; you can also use a different name if you change "id": "1.6.4_mods" inside the file, which must all match). Then, open the jar with an archive tool (7Zip, WinRar) and add the files within the zip you downloaded and delete META-INF (this is the same as installing any other non-modloader mod except for the json due to the 1.6+ launcher).

Note that I used this mod with Optifine (install in the same manner as described above by copying the contents of its jar over, not with its installer) but can't guarantee compatibility with any other mods, especially any that alter world generation, or Forge. In addition, I suggest adding the JVM argument -Xss1024K if you have a 32 bit system (64 bit uses this by default, 32 bit is 320K; increasing it further, but to no more than 2-4 MB, may also be helpful) since I occasionally get stack overflow crashes (MC-32168, due to very large water/lava flows) when generating new terrain without it; this is a pretty demanding mod due to 2-3x as much terrain generated per chunk and many more caves, with similar considerations to Amplified, but still much less demanding than newer versions.


Following are some screenshots and comparisons to normal world generation:

Normal generation vs. Double Height generation, as rendered with MCMap; note that the spawn point may change a bit but is within a few chunks in seeds I have tested (triple-height is similar but deeper):

As you can see here, terrain generation is identical other than being higher up and surface-based features being different (some things, like trees, don't use the world seed):

Comparison of with and without void fog, showing the reason for its removal (note that void particles are also removed, so if particles give you lag this can help a lot):

Comparison of caves between normal, double, and triple height generation:

Normal:

Double-height:


(note that even without the massive caves version of double-height cave systems can still become very large; this is actually a different world from the one shown above/MCMap renderings because that one had a massive cave system which I considered to be unrepresentative)

Triple-height (note, view at full size to compare maps, which all use the same scale):

Also, here is a supercolossal cave system in the massive caves version of double-height, followed by a large-scale (3008x4000) map:

Some screenshots of caves and ravines (some were taken using a texture pack, thus why water looks different in some):

Looking underground from the surface over a large cave system (note that even on Far render distance you can see fog in the lower caves):


Some giant caves:








And now some ravines:


This one looped around onto itself, leaving a floating pillar:


A very long drop (ravines can reach from the surface to bedrock, even in the triple-height version, although this is so rare that I've only found them by forcing the ravine height to the maximum value, but it is definitely possible):


A larger ravine as seen on Rei's Minimap, around 260 blocks long around the edge (one-way):

Here's another look at caves and ravines, taken by using the new spectator gamemode on my triple-height world:

Despite all of the caves, this is all you'll ever see at the surface, with a single cave opening per cave system (or more if several joined together), unless there is exposed stone or sand collapses into a cave/ravine:

These caves (generated separately from other caves) spiral downwards to bedrock, and cave systems have a minimum number of caves, virtually guaranteeing that they lead to something. There are also very long caves (up to about 560 blocks long, excluding bends) scattered around the map; while bigger on average, cave systems are also more separated and these caves act like a sort of "highway" between systems.



Note also that I do not plan to update this to 1.7 or beyond, at least for now, which poses problems because of the changes in terrain generation, which is now able to go to the world height limit; rarely, even in default (e.g. Savannah M) and I don't want to change the surface.

That said, you might want to try out these other mods I have made, including some for 1.7+:

TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4; this is a very comprehensive mod and the only one listed here that I still regularly update.

No Void Fog and Cave/Ravine Generation Mods (1.7.x) - removes void fog and disable, restore pre-1.7 cave generation, or add even more caves/ravines.

Superflat Caves (1.6.4/1.7.2) - adds caves to Superflat worlds, with new preset and configurations

Random Biomes (1.7.2), makes biomes generate randomly, like before 1.7, includes optional cave generation mod

As the title indicates, this is the first (non-demo) world I created when I got the game, appropriately named "World1", based on the seed -123775873255737467 in 1.5.1-1.6.4 (created in 1.5.1, 1.6.4 is almost the same except for no water lakes in deserts and different chest loot); the seed was randomly generated by the game (I don't think I even knew about seeds back then) and as it turned out it has been a very good seed, starting right from spawning, which places you near a village, no blacksmith but that doesn't really make a difference, near the intersection of a plains, desert, and jungle (open space for building, sand for glass, and wood). Of course, there are also plenty of caves underground, including several mineshafts within a couple hundred blocks of spawn (two overlapping at different levels to the southwest, where a large surface cave opening leads down to them, a third under the desert to the east), and an exposed ravine to the west, although that part came much later; I initially made a network of tunnels under my base and didn't really start caving until around two months had passed, based on an old copy of the world (caves that I intersected were walled off, much of this has since been "cleaned up").

Here are surface and underground maps of the area around spawn, as seen in the actual world and a recreated world in 1.6.4:

(I did not post an AMIDST map because I don't want to see what I haven't explored yet)

I had initially played on this world for around 6 months before I went off of it for about a year while playing around with modding the game, before returning back to it, first by modding a copy with a version of my mod "TheMasterCaver's World" (biome generation modified to have similar parameters to vanilla biomes they replaced so as to minimize chunk borders; here is a rendering of the modded world), then a second time after I'd played more modded worlds (for example); currently this is the only world I am playing on, with a total of around 1 1/2 years of daily gameplay, far longer than any other world I've had and representing about half the total time I've had or played Minecraft.

The world isn't entirely vanilla (beyond an area about X= +/-800 and Z= +1600); I modified the way mineshafts generate by removing their torches so unexplored mineshafts do not show up when I render the underground with MCMap (the mapping utility I used to make the 3D renderings you see in this thread), as well as preventing them from generating in areas with a lot of caves (they are still much more common than they are in 1.7 and later). This includes removing naturally generated torches from existing chunks (before I'd removed them from new mineshafts) by scanning them with code that removed torches attached to wooden planks in a particular manner underground (most of the torches I placed were left alone). I also made a few other modifications to my game, such as changing the way maps render and center themselves (similar to 1.7/1.8) and adding "rail blocks" and "cobweb blocks" which allow me to compactly carry and store rails and cobwebs, much like resources or wool (prior to this I crafted string from cave spider spawners into wool); note that I do not use them for long-term storage and there should be none in the world download (versions before 1.7 are particularly finicky about invalid items, regenerating chunks that contain any). In addition, this world has gone through a name change, by which I mean I had to manually edit the save so tamed animals would recognize my new name after I changed it when name changes came out, as 1.6.4 uses player names instead of UUIDs to keep track of data.

That being said, here are some renderings of the whole world (this and some of the following information may not be current; for example, I've since explored a large area to the east of what is shown below):

Minutor (day):

Minutor (night); yes, most of the light you see comes from cave openings, you can also see my main base in the center and villages (18 bases and 12 villages, including one in my main base):

Minutor (night at layer 22, near the layer of peak cave and mineshaft density):

Unmined, showing all explored caves underground after trimming away chunks without torches within a 1 chunk radius:

One thing that stands out is the lack of mineshafts closer to the origin (center), since they are less common within that area (linearly decreasing in frequency down to 0 at the origin from 80 chunks away along either axis)

Here is a close-up of my main base, along with some screenshots (a bit old but nothing major was changed):

This is the first part of my main base that I built, which has had changes to its layout since but has not been changed otherwise (enlarged, etc); I added the area shown above to expand it:


This is a more up-to-date look at the maps seen above (I modified item frames to render maps like 1.7+, in vanilla 1.6.4 they render like other items):



Part of my underground storage room, where I store all the resources I find while caving (the staircase in the screenshot above leads down to it); there are over two million resources stored here, and would be even if I did not use Fortune for a while after 1.6 came out, prior to which I also only mined what coal I needed, you can still find some caves with the coal left behind (I later re-explored most of these caves to remove the coal). I've mined more than a million coal ore alone, 400,000 iron ore, and some 100,000 other ores. Other resources include moss stone taken from dungeons, rails from mineshafts (also used in my railways), wool crafted from string mined from cave spider spawners (plus some cobwebs, which I only started collecting very late into the world after I added a mod block that let me craft them into blocks as you can with string and wool; these blocks are broken down for storage so there are no permanent modded blocks or items in the world), and loot taken from chests, plus some miscellaneous items such as a chest of mob drops):



A top-down view of the storage room made by deleting everything above it (made at a later date than the images above):



There is a large enclosed area with a glass roof, containing animals and oak trees; I originally made this area as an oak tree farm:

Besides my main base I have numerous secondary bases, of which a more recent one is shown below; most of these bases are relatively simple as they are mainly used as temporary storage areas (filling up a double chest, then I make a trip back to my main base) and to restock on food and wood; at least one older one has more things including enchanting setups and more farms, the latter of which are also seen in my newer bases since I've been trading to get emeralds so I can trade for diamond gear, which I started trading for after I found a villager selling diamond pickaxes, later on buying all gear:

Here is a full-size rendering (4256x3106 pixels, click to see a larger version) of an +/-8 chunk wide swath centered around the railway I made to this base, prior to exploring further; note the absence of caves around the base (which partly shows up on the cave map as parts of it are underground; my main base does not since I use glowstone), which is why I use MCMap to show my progress and removed torches from unexplored mineshafts (I even modified MCMap itself to use a small and more realistic range around torches, which also reduces near surface clutter in forests (MCMap counts any air space that has a 2+ block roof overhead as a cave):

Here is a list of the locations of the 22 bases that I've built, grouped according to the rail line they are on and numbered in the order I built them:

There are also a few structures not considered to be bases and which are not linked by railways scattered around, mainly in the area around base #3. Most of the railways are at y=58, though a short segment to the east of my main base is at y=63 (originally, most were but I moved them down; the railway to the east also went as deep as y=31 along the segment to the north, which I changed before the newest addition to the easternmost base).

Here is a list of the 15 villages I've found in the order I found them in (I did not actually record most of them but the way I explore makes it easy to figure out the earlier ones; #3 might have been found before #2).

Of course, as you can guess, the most notable thing about this world is the sheer amount of caves I've explored - nearly every cave, mineshaft, and ravine within generated chunks, save for a strip around the edges, has been explored with more than 3 million ore and nearly 4 million resources mined from them, and nearly a million torches placed; the exceptions are mainly caves that do not connect to anything else or the surface since the main way I find new caves is through interconnections underground, I'll also check out any surface openings I come across after I've explored an area but do not actively seek them out (most such openings are short dead ends).

Here are some statistics that give you some idea of just how much caving I've done in this one world, which has seen nearly half a year of continuous gameplay:

This is 4335 hours at an average of 3.53 hours per session, which is close to the average across all of my worlds; as an estimate about 90% of this time has been spent caving:



I've mined a total of about 3.11 million ore and 3.54 million blocks including moss stone, cobwebs, and rails, out of a total of 4.54 million blocks mined with a diamond pickaxe and shears (I used iron for a short time early on, now only used to dig out rail tunnels and build new bases using pickaxes taken from minecarts, keeping what I mine outside of caving separate):







I've also crafted 395,564 blocks of mineral resources (including 120 emerald blocks before I started mining it with Silk Touch), equivalent to 3.56 million resources, which when combined with moss stone, cobwebs (albeit most crafted into wool prior to using Silk Touch and cobweb blocks), and rails represents nearly 4 million resources collected over 1,228 play sessions, an average of 3,247 resources per session, even higher when only counting days spent caving:

Here are charts of what I mined over a 4 month period in 2021, during which I spent nearly every day caving with the exception of 2 days in October when I built a new secondary base and railway, otherwise my playstyle is remarkably consistent, with an average of about 3,100 ores and 3,600 resource blocks mined, 337 mobs killed, and 5400 XP collected every day (these figures more accurately reflect my caving than the general statistics shown above):

As for why I mine that many resources even though I do not use many of them, they are a byproduct of caving, which I do for fun, not to get resources; when I start a new world I branch-mine for resources and save caving until after I defeat the Ender Dragon, which to me is the "end" game; some of my worlds have even been "caving only" worlds, where I either used MCEdit to copy a base and gear over from another world or used Creative to build a base and give myself the items I use (either way, I only play in Survival while caving).

This is a series of surface and underground renderings over the six main periods I've played on this world (early-late 2013, mid-late 2015, most of 2016, mid 2017 to early 2018, two separate periods in 2020, and mid-late 2021; the time between these was spent on other worlds) and a full-size animation of an area I explored over several sessions:

This is full-size animation of an area I explored over 10 play sessions, each one lasting for 3-4 hours and covering an area of about 700x700 blocks overall, giving you an idea of how quickly I explore underground, which has included entire large (by 1.6.4 standards) cave systems, up to three separate mineshafts, and half a dozen ravines (not all at once):

A few underground screenshots taken with MCEdit (similar to Spectator mode):

Under my main base at spawn; compared to other areas this area includes a lot more tunnels between caves, as well as branch-mining at diamond level, which I no longer do in this world or in newer worlds except to get resources when I start out. There is still a staircase down from my storage area:



At -800, -1050 is the largest and densest single cave system in the world, and one of the largest and densest I've seen in any world:





Here is an Unmined rendering of the cave above (in a recreated world) showing just how dense that cave system is (from sea level and y=20, the latter of which shows denser caves better); it is unlikely I'll ever find another cave as large and dense as this one (I've found much bigger ones by scanning seeds for dense caves, I estimate that around a million chunks, 18-19 times the size of this world, need to be explored to find a cave like this):



That is not the largest cave system overall though; around -50, -1700 is a huge cave system/complex with more than a dozen separate mineshafts intersecting it:





Another big cave system is around 900, -70:



Not the entire underground is Swiss cheese though, as seen in this sparse area, including unexplored caves (in the upper-left is a desert temple):



It is also interesting just how close caves can get without interconnecting; here is an unexplored mineshaft that is just one block away from another one that I explored. If there had been ore or gravel here I'd have broken through (there are also often breaks in narrower caves and ravines, and larger breaks in ravines under the ocean, which I'll usually mine through):

You can download the world here to see it for yourself (dated 12/6/2021):

Note that while it can be opened in vanilla I recommend using my "World1 custom client", the mod I use to play on this world which includes many bugfixes and optimizations (this includes many fixes for bugs still present in the latest versions). It also includes many minor modifications and tweaks to gameplay, such as "rail" and "cobweb" blocks (these shouldn't be present in the download as I only use them for temporary storage while caving and at secondary bases). However, 1.8's Spectator mode makes it possible to fly around underground to get a good look at what I've explored (I did make it so the suffocation overlay isn't shown in Creative but currently you can't freely move around):

(the first few pages of comments were made back when I had posted this thread for the TMCW-modded version of this world; I decided to reuse this thread instead of making a new one with the same name)

Does anybody else come close to this level of caving? - I've always been interested if anybody else plays like me (surely there are, some have even told me that 1.7+ is unplayable without mods to bring back 1.6.4-style caves, which is also how I feel)

You can normally swap items from your inventory by hovering over it and pressing the number key for which hot bar slot you want it to go in. What im asking for is the ability to press "F" while hovering over a item to have it be put into your off hand and maybe the ability to access your off hand while looking in a container by using "F".

For the possible future cave update.

It seems strange to me that every dimension and even the ocean get their own soundtrack while the underground does not.

The music should play when below y=63 and not exposed to direct sunlight, and current Overworld air music should play when above y=63 or when in direct sunlight.

In other words, the music should play in caves including water caves but not for air caves open to the surface (i.e. not surface ravines or open faced caves, but an underwater ravine exposed to the ocean floor is fine).

Another way to manage when and where the music plays would be the new 'mood' factor, or maybe the difficulty factor.

Its tone should be darker than the ocean themes but not as dark as the Nether, and incorporating cave sounds such as common monsters, arachnopods, and bats, as well as cave ambience, could help improve a piece or even help C418 produce a piece just from those sounds remixed creatively.

Wdyt?
