Directional Blocks

Making blocks directional (facing into certain directions) is also done using block states. This example describes a vertical version of the andesite slab.

public class PolishedAndesiteSideBlock extends HorizontalFacingBlock {
 
	public PolishedAndesiteSideBlock(Settings settings) {
		super(settings);
		setDefaultState(this.stateManager.getDefaultState().with(Properties.HORIZONTAL_FACING, Direction.NORTH));
	}
 
	@Override
	protected void appendProperties(StateManager.Builder<Block, BlockState> stateManager) {
		stateManager.add(Properties.HORIZONTAL_FACING);
	}
 
	@Override
	public VoxelShape getOutlineShape(BlockState state, BlockView view, BlockPos pos, EntityContext ctx) {
		Direction dir = state.get(FACING);
		switch(dir) {
			case NORTH:
				return VoxelShapes.cuboid(0.0f, 0.0f, 0.0f, 1.0f, 1.0f, 0.5f);
			case SOUTH:
				return VoxelShapes.cuboid(0.0f, 0.0f, 0.5f, 1.0f, 1.0f, 1.0f);
			case EAST:
				return VoxelShapes.cuboid(0.5f, 0.0f, 0.0f, 1.0f, 1.0f, 1.0f);
			case WEST:
				return VoxelShapes.cuboid(0.0f, 0.0f, 0.0f, 0.5f, 1.0f, 1.0f);
			default:
				return VoxelShapes.fullCube();
		}
	}
 
	public BlockState getPlacementState(ItemPlacementContext ctx) {
		return (BlockState)this.getDefaultState().with(FACING, ctx.getPlayerFacing());
	}
 
}
