Hello,

I am trying to create a transparent block.

It looks like previous version of minecraft supported the following code:

    @Override
    public BlockRenderLayer getBlockLayer()
    {
        return BlockRenderLayer.CUTOUT_MIPPED;
    }

    @Override
    public boolean isOpaqueCube(IBlockState state) {
        return false;
    }

But 1.18 does not seem to have those classes.

This is my class:

public class ActivatedDisappearBlock extends Block {
    public static final BooleanProperty IS_ACTIVATED = BooleanProperty.create("is_activated");

    public ActivatedDisappearBlock(Properties properties) {
        super(properties);
        registerDefaultState(defaultBlockState().setValue(IS_ACTIVATED, Boolean.valueOf(false)));
    }

    @Override
    protected void createBlockStateDefinition(StateDefinition.Builder<Block, BlockState> builder) {
        super.createBlockStateDefinition(builder);
        builder.add(IS_ACTIVATED);
    }

    private boolean isVanished(BlockState state) {
        return state.hasProperty(IS_ACTIVATED) && state.getValue(IS_ACTIVATED);
    }

     // Compilation fails
    @Override
    public BlockRenderLayer getBlockLayer()
    {
        return BlockRenderLayer.CUTOUT_MIPPED;
    }

     // Compilation fails
    @Override
    public boolean isOpaqueCube(IBlockState state) {
        return false;
    }

    @Override
    public VoxelShape getShape(BlockState state, BlockGetter world, BlockPos pos, CollisionContext ctx) {
        return isVanished(state) ? Shapes.empty() : super.getShape(state, world, pos, ctx);
    }

    @Override
    public VoxelShape getCollisionShape(BlockState state, BlockGetter world, BlockPos pos, CollisionContext ctx) {
        return isVanished(state) ? Shapes.empty() : super.getCollisionShape(state, world, pos, ctx);
    }

    public void neighborChanged(BlockState blockState, Level level, BlockPos blockPos, Block blockIn, BlockPos fromPos, boolean isMoving) {
        if (!level.isClientSide) {
            System.out.println(blockState);
            if (blockIn instanceof ActivatorBlock){
                ActivatorBlock activator = (ActivatorBlock)blockIn;
                BlockState state = level.getBlockState(fromPos);
                var activating = state.getValue(IS_ACTIVATING);
                System.out.println(activating);
                blockState = blockState.setValue(IS_ACTIVATED, activating);
                level.setBlock(blockPos, blockState, 3);
                level.blockEntityChanged(blockPos);
                level.updateNeighbourForOutputSignal(blockPos, blockState.getBlock());
            }
        }
    }
}

Or can I change the render type of my block to -1 as according to the following old documentation that would make it not rendered (like air).

You need to set the RenderLayer in FMLClientSetupEvent via ItemBlockRenderTypes#setRenderLayer 

Thanks a lot.
I was able to figure out how to use the ItemBlockRenderTypes.setRenderLayer with your advice
