    posted a message on How to colour the inside of walls but not the outside

    Maps in item frames would do it though it would take 256 stacks of white blocks to get an all white map of the smallest size, or find a large expanse of snow, then there'd be less that had to be filled in manually.


    Or use cheats and the /fill command.

    posted a message on How can I fix my simple sliding door?

    If I've got things straight it's the glass block in my screenshot that has something stopping you from putting redstone on it?


    Can you run the redstone an even more roundabout route so it comes in straight at the torch block, like I've done?

    Quote from minebunny69»

    That'll be it then. I assumed the same spawning rules applied as when you're near a dungeon - i.e. if you're not near it they won't spawn-which is why I built it directly underneath my house, so whenever I'm there they would be spawning like crazy. Ho-hum.

    Don't have the console switched on right now (regarding version) but I play whatever is the latest update of the Better Together edition on the Xbox. I'm a bit confused as some people refer to this as Bedrock and some as Java, unless I'm completely barking. Anyway, thanks for the replies. I'll investigate plugging a direct keyboard in for the F3 thing as I normally use a wireless keyboard/mouse via dongle combo, and see if that fixes that.




    Ah, no, cage spawners work in the opposite way to normal spawning.


    Anybody calling anything on Xbox the Java edition is either a master hacker or confused themselves.


    Java MC only works on PC (Windows or Linux) and Mac.


    The confusion is probably largely caused by the Windows 10 edition which is Bedrock/Better Together (also referred to as just "Minecraft" now days) :angry: for Windows 10 PCs (and possibly Win 10 phones if they still exist).

    So, we, the Glorious PC Gaming Master Race :P

    get to play either Java or Bedrock (at least those of us running Windows 10)

    posted a message on How do i replace one layer in a world with a block.

    I've come up with something that I think would work better, based on what I think you want.

    There may well be a better way, perhaps using execute...if block(s) but I'm no good with commands, this is a bit of a kludge but I think it would work.

    I probably won't have time to work through it and get it working properly, this is just the general idea.


    The idea is to have a grid of 9 boxes around the player and a string of 16 command blocks in the spawn chunks, 2 for each of the outer boxes.

    First an unconditional command block that uses fill to replace the bottom layer of bedrock in that box with obsidian (or air or whatever), if it finds any bedrock the command succeeds and the next, conditional command block replaces all blocks in that box at your chosen level with your chosen block, then the next, unconditional command block tests the next box followed by a conditional command block to fill in your block, and so on for the rest of the outer boxes.


    This should create a solid unbroken layer of your block (except for where the player is standing when you start this, which would require a separate one time command) but won't replace broken blocks in any area the player has visited, just extending the layer when the player gets close to somewhere they haven't been before.


    You might want the boxes to overlap a bit to make sure no area is missed.


    --

    Oh, and teleporting players and players returning through new portals in the Nether might also end up with no layer at their position.

    posted a message on How do i replace one layer in a world with a block.

    Unless you can find a mod that does that or a modder willing to write one (or are willing to settle for a superflat world) the best I can think of would be a string of command blocks in the spawn chunks repeatedly running /fill around the players position.

    Assuming you want a player to be able to dig through the layer you can't replace air with your block so I think you'd need one command for, at least, each type of stone and if you want a solid layer each type of ore as well. (You'd still get holes where caves intersect your layer.)

    If you are ok with doing this for a limited area you could fly around the world filling in the layer first and then disable the command blocks.

    Actually in that case you could settle for one command block making a totally solid layer.

    If you are going to play the world yourself and don't want hints on where to find things you could fly around under the bedrock floor, without a map it might be hard to be certain you hadn't missed anyplace though it could be done by following the coordinates on the debug screen.


    Do you mind explaining the purpose?

    I'm particularly curious about why you want it added after world generation, any existing mod that added something like this would probably do it in world generation.


    --

    If the commands are going to be running constantly you might want to use a redstone clock to run the command blocks once every second or two instead of multiple times per second, like the auto repeat function does, in order to cut down on lag.

    posted a message on Can these pistons be controlled separately?

    Hooking it up to use switches instead of toggle buttons wasn't as hard as I thought either.


    I just replaced the buttons with observers with switches on the front and repeaters set to the second or third step.


    I'm sure the switches could be replaced with redstone dust hooked up to a signal source though you'd have to make sure that only one signal could change at a time.


    I actually hooked up both the observers and buttons to allow for syncing the blocks to the positions of the switches.

    Hooking it up so you only need one button per piston turned out to be as easy as just connecting the buttons with redstone dust and repeaters with a small delay.

    What he said.


    Plus you need to be at least 24 blocks away for anything to spawn, so nothing is going to spawn in your basement as long as you are directly overhead.


    Specifically mobs will only spawn between 24 and 128 blocks away from your position.

    (And that's the 3D Euclidean distance (a straight line as measured with a ruler) not Taxicab distance (counting block edges)).

    posted a message on Trouble with fill (outline, replace, etc)

    Hi,

    Back in 2017 the command needed data values or states for the blocks.

    I never really understood how to use them but


    /fill ~ ~ ~ ~10 ~10 ~10 water 0 replace air 0


    seems to work.


    Here's the link to an appropriate version of the Wiki page for the /fill command.

    posted a message on Can these pistons be controlled separately?

    I've got a circuit that might be useful, it sort of depends on how you are thinking of using it.


    To start with it doesn't actually let you set the positions of the pistons but rather lets you change the positions of the blocks that the pistons push and pull but I expect that would be what you really want.


    Secondly it doesn't let you flip a switch to decide whether a block is in the in or out position, you get to push a button (or 2 or 3) to toggle the position.


    My build is pretty messy but it is made of simple pieces that you ought to be able to connect yourself (not that I won't try to make it simpler to see what's going on.): screenshot 1


    Ok, the principle is that a zero tick pulse shortener, screenshot 2, sends a very short pulse to one or more sticky pistons, this causes them to either push out a block but fail to pull it back or to extend empty and pull the block back. So every other pulse the block is pulled back and every other left in the extended position. The signal has to be connected to the piston and block that form the pulse shortener with either redstone dust or a repeater so that both the piston and block are powered and you need a repeater after the block to power the pistons.


    Now, as you saw, you can't control just one piston in the middle of a stack.

    But you can control the top and bottom pistons.

    And you can control the stacked pistons 2 at a time.


    If you don't mind the wrong blocks being moved back and forth as long as they end up in the right place, you can toggle piston #2 by first toggling #1 and then #1 and #2, since #1 is toggled twice it ends up back where it started..

    Likewise #4 can be toggled with #5 + #4and#5.

    And #3 would be #1 + #1and#2 + #2and#3 (or #5 + #5and#4 + #4and#3)


    It doesn't matter if you change the order in which the pistons are toggled.


    Screenshot 3 shows at which levels you need to connect the signals to the pistons.


    --

    I'm pretty sure that it wouldn't be too hard to hook the circuits up so you only needed to push one button instead of three to toggle the middle piston, though it would of course increase the complexity.


    Hooking it up to use switches to control the positions is presumably possible but it would probably be very complicated.

    Those are "underwater ruins" or "ocean ruins".

    They usually generate underwater but not always.

    They should have a treasure chest inside or buried underneath.

    posted a message on How nether portal horses =

    One issue with pushing mobs through portals that may be unlikely to occur in normal situations but might be worth knowing about is that one should always use a nether portal oneself at least once before trying to push mobs through.


    In at least some versions of Minecraft a mob can't go through a portal if there isn't a portal at the other end (the exit portal isn't created until a player uses the portal).

    And there is (or was at least) a bug that kept a mob that had failed to go through a portal because the exit portal didn't yet exist from ever going through a portal.
