Great job man.

Hello everybody, my name is th0mas_87. Welcome to my Minecraft Modification Development Tutorials for use with ModLoader 1.5 and Minecraft 1.5! If you want to, check out all my mods on PMC and my most popular mod, the PSY Gangnam Style Mod :-)

To edit and create Java code, you must have both a Java JDK installed on your computer and your computer's PATH variable correctly set up.

Java JDK
First, visit this link, click the "Java Platform (JDK) 7u17" button, accept the license agreement, and download the "jdk-7u17" file for your operating system. Then, run the downloaded installer application and follow the instructions to install the Java JDK.

PATH Variable
The procedure for changing the PATH variable is different based on the version of Windows your are using. I will only be covering the procedure for Windows 7, so if you are using a different version, visit this tutorial.

Windows 7

1. Open a Windows Explorer window and right click the Computer icon.
2. Select Properties from the menu.
3. Click the Advanced System Settings link on the left.
4. Click Environment Variables. Find the PATH variable in the System Variables section. If it does not, click New and create it. Click Edit.
5. Open a Windows Explorer window and navigate to C:\Program Files\Java\jdk1.7.0_17\bin or wherever your JDK's bin folder is located.
6. Right click the address bar at the top and select the Copy address option.
7. Navigate to the beginning of the text within the editing window of the PATH variable and paste the address you copied along with a semicolon after it.
8. Click OK. Close all the remaining windows by clicking OK.

Eclipse is a Java IDE which allows for maximum efficiency and comfort-ability whilst editing and creating Java code. MCP (Mod Coder Pack) is a tool that allows the user to decompile, edit, add to, and recompile Minecraft source code. I will be using Eclipse for all of the coding done in these tutorials.

Eclipse
To download Eclipse:

1. Go to eclipse.org/downloads/.
2. Locate the "Eclipse IDE for Java EE Developers" link and click the link to the right of it that corresponds to the version of Windows that you are running, 32 bit or 64 bit.
3. Click the download button.
4. Extract the contents of the zip folder that you downloaded to another folder with a tool with the capabilities of 7zip or WinZip.
5. [Optional] Open the unzipped folder, locate eclipse.exe, and create a shortcut on your Desktop.

• Download the latest version of MCP (Mod Coder Pack).

• Download the latest version of ModLoader.

• Download the latest minecraft_server.jar.

• Force update Minecraft. To do so, launch Minecraft, click the Options button, click Force Update, and then login. When you reach the main menu, if it is your first time playing Minecraft on the Windows user you are on, make sure to create a world, or else the sounds will not download. Then, exit Minecraft.

• Create a new folder (it can be anywhere, mine is on my Desktop), and name it "Minecraft Modification Development for Minecraft 1.5".

• Open a Windows Explorer window and navigate to C:/Users/[Your User]/AppData/.minecraft/bin and copy the bin and resources folders.

• Navigate to the Minecraft Modification Development for Minecraft 1.5 folder you created and paste the bin and resources folders you copied.

• Locate the files you downloaded: ModLoader.zip, mcp***.zip, and minecraft_server.jar; and move them to the Minecraft Modification Development for Minecraft 1.5 folder.

• Extract the contents of mcp***.zip to a new folder within the same directory with a tool with the same capabilities of 7zip or WinZip.

• Rename the extracted folder to "Base Mod".

• Copy the bin and resources folder. Navigate to Base Mod/jars and paste the bin and resources folders you copied.

• Navigate back to the Minecraft Modification Development for Minecraft 1.5 folder. Copy the minecraft_server.jar. Navigate to Base Mod/jars and paste the minecraft_server.jar.

• Open the bin folder. Then, open minecraft.jar with a tool with the same capabilities as 7zip or WinZip.

• Navigate back to the Minecraft Modification Development for Minecraft 1.5 folder and open ModLoader.zip with a tool with the same capabilities as 7zip or WinZip. Then, copy all the files within ModLoader.zip and paste them in minecraft.jar. Delete the META-INF folder in minecraft.jar. Close minecraft.jar and ModLoader.zip.

• Navigate to the Base Mod folder and run decompile.bat.

• Wait patiently as the decompile.bat terminal informs you of what it is doing. Do not panic about the "ignored" and "FAILED" hunks within the "Error Message" for they are expected.

• When the decompile.bat terminal tells you to "Press any key to continue", press any key to continue.

• Navigate to the Minecraft Modification Development for Minecraft 1.5 directory. Then, copy and paste the Base Mod folder.

• Rename the Base Mod - Copy folder to the name of your mod. Make sure to copy and paste Base Mod for every new mod you wish to create or else you will have to go through this whole process again. Do not edit anything within Base Mod.

• Run eclipse.exe. When prompted for the location of your workspace click the Browse button and navigate to Minecraft Modification Development for Minecraft 1.5/[Name of Your Mod]/eclipse. Then click OK twice to close the browsing window and confirm your selection.

Great job! You have decompiled the Minecraft source code and are now ready to make your first mod!

That's it for now. Further tutorials are WIP and will be posted ASAP

Quote from Fog_Terminator

Name of Mod: Ellipsoid Generator

Time it should be done by: Take however long you want.

Description of what the mod adds: This Mod would a generation of ellipsoids in creative mode Minecraft. You would be able to select a block of choice to generate the ellipsoid then click on the two furthest corners of the 3 dimensional block it would take up to create the desired shape and size. To select these things there would be a new non-craftable item in the game. The way that the ellipsoid is generated does not matter that much if you want to change it, as long as it generates it in a user friendly way.

What the mod adds:

A selection tool

Ellipsoid Generation

P.s This is a pretty good explanation of what ellipsoids are if you are not sure: http://en.wikipedia.org/wiki/Ellipsoid

Description of what the mod adds:
Lets time run slower i.e. makes day and night last longer (I would prefer 3 times slower)
Various people have coded this before:
http://www.minecraft.../#entry19545454 (never worked, discontinued)
http://www.minecraft...ol-of-daylight/ (discontinued)

Are you interested ?

Thank you for saving me from yelling at people, and good question. I do know he's moving on from some of the smaller projects he's finished to more village buildings.

Quote from Vetro7

PLEASE make a simple mod where the chests go back to being full blocks just like in the early beta. It dose not really need to be a re-texture, just so that the chest has no airspace between itself and the wall. Please also make it where it works in SMP (just client side, not for everyone on the server)

I REALLY need this mod and i have been looking everywhere!

Quote from Wyrenth

Name of Mod: More Leather from Animals (or Improved Animal Drops)

Deadline: None (but the sooner the better)

Description:
The mod would make the following changes to mob drops:
- Cows: Instead of dropping 0 to 2 leather, drop 4 to 8 leather. Meat remains unchanged (or improves to 3 to 6).
- Mooshrooms: Same as Cows.
- Pigs: In addition to normal drops, drop 0 to 2 leather. Meat remains unchanged (1-3 seems fair for its size).
- Sheep: In addition to normal drops, drop 0 to 2 leather.
- Wolf (wild/tamed): Drops 1 to 2 leather.
- Chickens: Instead of dropping 0 to 2 feathers, drop 4 to 8 feathers. Meat remains unchanged.

Option: If mob dies by fire, leather and feather drops are 0. (not a priority, but would make sense)

Cats and bats seem like too small of mobs to get an appreciable amount of leather from, squids are too thin-skinned, and a zombie's rotten flesh isn't tannable.

What the mod adds:
The priority here are making cows more logically drop greater amounts of leather. Sure, you could breed more, but I'm sure I'm not the only one frustrated by the fact that, even if you were the sloppiest butcher ever, you can't strap a single cow carcass to your head and make a hat. With leather being used in so many more recipes now, the illogic of how few materials you get from one cow becomes even more glaring.

Everything else outside of improving cow drops is just to flesh out the concept.

If someone else has already made this, I'd appreciate being pointed in their direction. Google and other searches have failed me... the best I found was rotten flesh to leather, which isn't what I'm looking for here.

Thanks for your time.

Try to replace stone with cobblestone I guess, but I'll browse through the creative menu today for some better ideas, and maybe find a place to host some pictures.

Quote from Manan6619

Hi thomas, how is More Village Buildings going? I'd like to request one thing: Please, try to avoid putting smoothstone in the structures from now on! Any time you put stone in the natural generation, it is always possible for ores, dirt, and other sh*t ­ to generate in it. (I wonder if it can spawn lava pools, too? ) Anyways I look forward to more pictures of progress, and I also hope you're willing to update it to 1.4.6. Thanks again for being open to request, though!
