How to use the 3D Stage to draw a 3D box?
Posted: Fri Oct 21, 2022 12:09 am
I tried to draw a 3d box on a 3d scene but failed...
When using RotateMatrix angle != 0, sprites move far to the side. The same thing happens when using an OffsetMatrix.
(It’s also sad that linear and ease doesn’t work when using matrix transformations.)
I want to make a scene where you can go behind the boxes and find some items there.
