Changing block texture depending of the direction it was placed

Recommended Posts

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" }
      }
    }
  ]
}

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 :

Maybe you know this error and why it crashes?

    • idk how to reply here but no im not coding any mod, all of them are downloaded but its only gfs computer, on mine its ok and i was looking all around the internet and never seen anything similiar atleast  
    • I changed it to public static void but I can't find anyway to get level from the event even if it isn't a listener parameter. @JimiIT92
    • I didn't yet see this happening on 1.20.2 forge, but sadly, I noticed that my mod is incompatible with this version because of this event handler: @SubscribeEvent public static void onPlayerRightClickItem(PlayerInteractEvent.RightClickItem e) { if (e.getItemStack().getItem() instanceof EggItem) { List<ThrownEgg> eggs = e.getLevel().getEntitiesOfClass(ThrownEgg.class, new AABB(e.getEntity().blockPosition().immutable() .below(5) .north(5) .west(5), e.getEntity().blockPosition().immutable() .above(10) .south(5) .east(5))); if (!eggs.isEmpty()) { eggs.forEach(ThrownEgg::discard); if (!e.getEntity().getAbilities().instabuild) e.getItemStack().grow(1); } if (!e.getEntity().level().isClientSide) { ((ServerPlayer) e.getEntity()).connection.send( new ClientboundStopSoundPacket(SoundEvents.EGG_THROW.getLocation(), SoundSource.PLAYERS)); // Minecraft Forge 1.20.2 crashes because of NoSuchMethodError here } e.setCancellationResult(InteractionResult.SUCCESS); e.setCanceled(true); } }  
    • It might just be a misleading log, if you run the command while debugging what's the outcome?  I've tried checking the item inside the RightClickBlock event and it works just fine private static final Ingredient FOOD_ITEMS = Ingredient.of(Items.WHEAT_SEEDS, Items.MELON_SEEDS, Items.PUMPKIN_SEEDS, Items.BEETROOT_SEEDS, Items.TORCHFLOWER_SEEDS, Items.PITCHER_POD); @SubscribeEvent public static void onRightClickBlock(final PlayerInteractEvent.RightClickBlock event) { final ItemStack itemStack = event.getItemStack(); LOGGER.info(FOOD_ITEMS.test(itemStack) + ""); } When I right click a block with an Item it checks if is one of the ingredients of FOOD_ITEMS. Clicking with an empty hand (air) logs false, as expected. Tip: please use the "spoiler" tags for long code snippets and don't merge all your classes into one code snippet EDIT: just noticed you are on 1.20.1. Maybe is just a bug with the Forge version? Try update to the latest Forge 1.20.2 and see if it still occurs
    • I created a temp command with this syntax: /isfood <entity to check> <player to check the item in main hand or off hand> It outputs either string respiration of an ItemStack (<count of items> <item name>) that player holds in his hand if it's a food item for specified entity, or "none" if specified player isn't holding an item which is a food item for the specified entity. Command's code if you didn't understand: event.getDispatcher().register(Commands.literal("isfood").then(Commands.argument("animal", EntityArgument.entity()) .then(Commands.argument("player", EntityArgument.player()).executes(context -> { Entity entity = EntityArgument.getEntity(context, "animal"); Player player = EntityArgument.getPlayer(context, "player"); if (entity instanceof Animal mob) { if (mob.isFood(player.getItemInHand(InteractionHand.MAIN_HAND))) context.getSource().sendSuccess(() -> Component.literal(String.valueOf( player.getItemInHand(InteractionHand.MAIN_HAND))), true); else if (mob.isFood(player.getItemInHand(InteractionHand.OFF_HAND))) context.getSource().sendSuccess(() -> Component.literal(String.valueOf( player.getItemInHand(InteractionHand.OFF_HAND) )), true); else context.getSource().sendSuccess(() -> Component.literal("none"), true); } return 1; })))); So, I tested it on my entity, and command output was: 0 air (also want to say that it happens only if I play Minecraft for a long time) Anyways, the entity code: package mymod.entities.chicken;
