Hi, I'm trying to add a block with a custom model and hitbox, that can face in any horizontal direction, because of that I need a VoxelShape for each direction. Now my question is, do I have to define each VoxelShape by hand or is there a function to rotate a VoxelShape?

no you have to do it manually

That said, it wouldn't be hard to write that function.
You just have to do the following:

X1 -> -Y2
Y1 -> X2

Unfortunately that's not the case. I tried to write a function for this, but the VoxelShape is based on 3D points (x, y, z).

The problem is you need to define a 3D rotation point and need to move all other points related to this rotation point. 

In the end it was easier for me to draw (or rotate) a box in Blockbench and just write down the needed points. 😅

My post was about rotation only around Y. For X and Z you just need to swap out the X and Y for X/Y/Z as necessary and then remember to perform the rotations in the correct order.

Usually X, then Y, then Z.

Or you can use a quaternion.

Point is, because the rotations are in 90 degree increments, the coordinates just exchange places with each other with the occasional -1

Thanks!
