Changing block texture depending of the direction it was placed

TokiiWalkie · February 6, 2021

Hello, I’m pretty new in the Minecraft modding community, and I’m having a lot of difficulties, since i’m a beginner. Actually, I’m working on a big railway project on Minecraft, and I wanted to create a mod that fills what is missing. I started by doing a platform indicator block to indicate the player the train he needs to take (a texture example is attached). But my stations won’t be all in the same directions, so I need to make a block that has different faces depending on the player position, but I don’t know how to do.

I tried some researches on the Internet, I tried to find answers in the source code of other mods, but I can’t figure how to do this kind of block

Maybe using BlockState? I really don’t know...

Here is my project structure :

Here is some codes :

# Block class
  public class PlatformIndicatorBlock extends Block {
    public PlatformIndicatorBlock() {
        super(AbstractBlock.Properties.create(Material.CLAY, MaterialColor.LIGHT_BLUE)
                .hardnessAndResistance(2f, 6f)
                .harvestTool(ToolType.PICKAXE)
                .harvestLevel(1)
                .sound(SoundType.STONE));
    }
}

// Blockstate file
{
  "variants": {
    "": { "model": "twlksrailwayproject:block/platform_indicator_block" }
  }
}

// Model file
{
  "parent": "block/cube",
  "textures": {
    "front": "twlksrailwayproject:blocks/platform_indicator_block_front",
    "side": "twlksrailwayproject:blocks/platform_indicator_block_side"
  },
  "elements": [
    {
      "from": [0, 0, 0],
      "to": [16, 16, 16],
      "faces": {
        "down":  { "texture": "#side", "cullface": "down" },
        "up":    { "texture": "#side", "cullface": "up" },
        "north": { "texture": "#front", "cullface": "north" },
        "south": { "texture": "#side", "cullface": "south" },
        "west":  { "texture": "#side", "cullface": "west" },
        "east":  { "texture": "#side", "cullface": "east" }
      }
    }
  ]
}

(Sorry for bad english, I’m french and not fluent yet ^^’)

Have you tried looking at the vanilla blocks that do this (furnace, for example)?

I was looking for this kind of blocks, but i can’t find it on the internet

Maybe you have a link?

So, I’ve been looking for the source code of the furnace block, but it was a bit too complicated for me ^^'. So, I searched on the source code of the mod "IronFurnaces", and I found something interesting :

public class PlatformIndicatorBlock extends Block {
    public PlatformIndicatorBlock() {
        super(AbstractBlock.Properties.create(Material.CLAY, MaterialColor.LIGHT_BLUE)
                .hardnessAndResistance(2f, 6f)
                .harvestTool(ToolType.PICKAXE)
                .harvestLevel(1)
                .sound(SoundType.STONE));
    }

  	// What I’ve added
  
    @Override
    public BlockState getStateForPlacement(BlockItemUseContext ctx) {
        return (BlockState) this.getDefaultState().with(BlockStateProperties.HORIZONTAL_FACING,         ctx.getPlacementHorizontalFacing().getOpposite());
    }
}

But now, it creshes when I try to place the block :

// You're mean.

Maybe you know this error and why it crashes?

Wrong model file

TokiiWalkie · February 7, 2021

I guess it works now, my game does not crash, but now my texture isn’t showing on the block

TokiiWalkie · February 7, 2021

Ok thank you it works now (I have forgotten to change minecraft: to my mod id).
