自定义碰撞箱,因为是不规则方块，所以每个朝向的碰撞箱不一样

private final static VoxelShape SHAPE_NORTH= Block.box(5, 0, 6, 11, 14, 10);  
private final static VoxelShape SHAPE_EAST= Block.box(6, 0, 5, 10, 14, 11);  
  
@Override  
public VoxelShape getShape(BlockState blockState, BlockGetter blockGetter, BlockPos blockPos, CollisionContext collisionContext) {  
    switch (blockState.getValue(FACING)){  
        case SOUTH, NORTH:  
        default:  
            return SHAPE_NORTH;  
        case WEST, EAST:  
            return SHAPE_EAST;  
    }  
}

VoxelShape可以从Blockbench中Model Utils插件中导出带有VoxelShape的java源代码文件，加以修改即可

新建net.emtips.leespeaker.CustomBlock包 Speaker_Block类
