I want to render a fake block (a block that only has texture and can be skipped). I came to something like this, but I don't know what to give to the renderSingleBlock method Minecraft.getInstance().getBlockRenderer().renderSingleBlock(blockstate, posStack, bufferSource, pakcedLight, packedOverlay, modelData, renderType); I want to put the textures of the game blocks for the fake blocks, but if I can also put custom textures, that would be fine.

How can I show a list as a suggestion in a command for the player to choose from?

I know that with this you can return the game folder FMLPaths.GAMEDIR.get() I want the player to be created in the world where a txt file was created in the folder of the same world. How can I return the path of the world folder that the player is in?

I'm sorry, but if possible, please write the code on how to save and how to get it

I know that with this you can save a data in nbt data of a player player.getPersistentData().putInt("value", 0); Is there any way to save this data in nbt data world instead of nbt data player?
