just something I made with @mathmathmath's 3D pen graphics tutorial. Check it out if you want to make 3D stuff, it's really helpful. I wanted to just have shapes ready to use, like a circle, square, and other stuff, but this didn't really prove to be that useful, as it would require some extreme modding every time I drew a shape in a different place. So I did what I thought I needed to do, and I made it so it has a square that you can shape the sides on, x y and z ways, and move it x y and z. So all it needs is to get some wall detection, and we are all good!
Thanks to @mathmathmath for his 3D pen graphics tutorial. Use E to pause/unpause the game, and set the sliders, and wasd to move and shift to run with mouse to control view.
