I have made a basic 3D engine in microsoft makecode arcade, it currently renders a 3d cube that you can walk around and rotate, but the z-clipping is horrible and makes it an unpleasant experience. I want to implement something like they show in this scratch tutorial, but I'm not really good at that kind of stuff. If you want to help, go to this link to edit the code
Thanks!
At first I tried to just not render a triangle if any one of its vertices were behind -140z, but that wasn't very visually appealing as triangles disappear once they got close
