[1.20.1] Need help with big block's collision box

Recommended Posts

I'm currently implementing an Oil Pump block. It's bigger than a regular block and is loaded with the wavefront (.obj) loader provied by Forge.

I'm trying to add collision boxes to my block but some of my collision boxes are bigger than 16x16x16, and i can walk through them...

Here's what I override to create my bounding boxes :

@Override
    public VoxelShape getShape(BlockState state, BlockGetter world, BlockPos pos, CollisionContext context) {
        return switch (state.getValue(FACING)) {
            default -> Shapes.or(box(-5, 2, 17, 37, 53, 32), box(-5, 2, -13, 37, 53, 2), box(-12, 0, -20, 44, 4, 53), box(6, 1, 43, 26, 26, 62), box(9, 49, 2, 23, 53, 17));
            case NORTH -> Shapes.or(box(-21, 2, -16, 21, 53, -1), box(-21, 2, 14, 21, 53, 29), box(-28, 0, -37, 28, 4, 36), box(-10, 1, -46, 10, 26, -27), box(-7, 49, -1, 7, 53, 14));
            case EAST -> Shapes.or(box(17, 2, -21, 32, 53, 21), box(-13, 2, -21, 2, 53, 21), box(-20, 0, -28, 53, 4, 28), box(43, 1, -10, 62, 26, 10), box(2, 49, -7, 17, 53, 7));
            case WEST -> Shapes.or(box(-16, 2, -5, -1, 53, 37), box(14, 2, -5, 29, 53, 37), box(-37, 0, -12, 36, 4, 44), box(-46, 1, 6, -27, 26, 26), box(-1, 49, 9, 14, 53, 23));
        };
    }

My question is : Is there a way to bypass the collision box size limit on blocks ?

A block should never be bigger than the standard 16x16x16 size. If you need something bigger than that you should split it into several different blocks (like how tall grass does it).
