Transparent textures on blockmodels

[bajtix]

Hi,

I have a problem with my blockmodels or maybe it's in my code.

I am trying to add a transparent texture to my blockmodels, so it has two layers. However, ingame, the transparent parts become black.

Here's a screenshot:

 

//Block implementation
public static Block candle = new VaseBlocks(Block.Properties.create(Material.ROCK)
            .hardnessAndResistance(2.0f, 3.0f)
            .sound(SoundType.STONE)
            .lightValue(10)
    ).setRegistryName(MainClass.location("candle"));

//VaseBlock class
//The candles use the same class for my vases
package com.bajtix.onesblocks.blocks;

import com.bajtix.onesblocks.lists.BlockItemList;
import net.minecraft.block.Block;
import net.minecraft.block.BlockState;
import net.minecraft.block.HorizontalBlock;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.BlockItemUseContext;
import net.minecraft.state.DirectionProperty;
import net.minecraft.state.IntegerProperty;
import net.minecraft.state.StateContainer;
import net.minecraft.util.*;
import net.minecraft.util.math.BlockPos;

import net.minecraft.world.IBlockReader;
import net.minecraft.world.World;
import net.minecraft.world.server.ServerWorld;

import java.util.Optional;
import java.util.stream.Stream;

public class VaseBlocks extends Block {

    public static final DirectionProperty FACING = HorizontalBlock.HORIZONTAL_FACING;
    private static final Optional<VoxelShape> SHAPE = Stream.of(
            Block.makeCuboidShape(2, 0, 2, 14, 5, 14)
    ).reduce((v1, v2) -> {
        return VoxelShapes.combineAndSimplify(v1, v2, IBooleanFunction.OR);
    });
    public static IntegerProperty COUNT = ModBlockStateProperties.VASE_COUNT;


    public VaseBlocks(Properties p_i48440_1_) {
        super(p_i48440_1_);

        this.setDefaultState(this.getStateContainer().getBaseState().with(FACING, Direction.NORTH).with(COUNT, 1));
    }

    @Override
    public VoxelShape getShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
        return SHAPE.get();
    }

    @Override
    public BlockState getStateForPlacement(BlockItemUseContext context) {
        return this.getDefaultState().with(FACING, context.getPlacementHorizontalFacing().getOpposite());
    }

    @Override
    public BlockState rotate(BlockState state, Rotation rotation) {
        return state.with(FACING, rotation.rotate(state.get(FACING)));
    }

    @Override
    public BlockState mirror(BlockState state, Mirror mirrorIn) {
        return state.rotate(mirrorIn.toRotation(state.get(FACING)));
    }

    @Override
    protected void fillStateContainer(StateContainer.Builder<Block, BlockState> builder) {
        builder.add(FACING);
        builder.add(COUNT);
    }

    @Override
    public ActionResultType func_225533_a_(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand hand, BlockRayTraceResult result) {
        if (!worldIn.isRemote) {
            ServerWorld serverWorld = (ServerWorld) worldIn;
            if (state.get(COUNT) < 3 && player.getHeldItem(hand).getItem() == BlockItemList.vase) {
                if (!player.isCreative())
                    player.inventory.getCurrentItem().setCount(player.inventory.getCurrentItem().getCount() - 1);
                serverWorld.setBlockState(pos, state.with(COUNT, state.get(COUNT) + 1));
            }
        }
        return ActionResultType.SUCCESS;
    }


}

You may need to use RenderTypeLookup.setRenderLayer on your blocks in FMLClientSetupEvent, i.e.

RenderTypeLookup.setRenderLayer(NEWBLOCKS.FIREFLOWER.get(), RenderType.getCutout());

I believe this needs to be done using a DeferredWorkQueue

 

*edit: I guess I should have asked what version, this is how I fixed a similar issue in 1.15.2.

Hi

Do you mean

* fully transparent (i.e. each pixel is either present or absent) - in which case getCutout is the right renderlayer

* partially transparent (i.e. alpha blending - like glass panes where you can see through them) - in which case you will probably need to use a Forge multilayer block

PS forgot to mention - for multilayer you will also need to set the RenderLayer like this:

  @SubscribeEvent
  public static void onClientSetupEvent(FMLClientSetupEvent event) {
    RenderTypeLookup.setRenderLayer(StartupCommon.blockGlassLantern, StartupClientOnly::isGlassLanternValidLayer);
  }

  // does the Glass Lantern render in the given layer (RenderType) - used as Predicate<RenderType> lambda for setRenderLayer
  public static boolean isGlassLanternValidLayer(RenderType layerToCheck) {
    return layerToCheck == RenderType.getSolid() || layerToCheck == RenderType.getTranslucent();
  }

Thanks to all people who answered, I'm going to give the solutions a try tommorow.

Do not create blocks and other registry entries in static initializers.

I am going to rewrite it to deffered registries. I thought I'd do it later, but i think i should do it ASAP.

Just want to say thank you for this thread - it has solved several hours of headaches. I thought I had issues with my textures and/or code for registering new blocks, and had been going over everything, again and again.
