Like Wolfenstein 3d or the original DooM? It was raycasting back in those days. I was wondering if theres any way we could do that with c2? I know @Yann did somethin like that in his maze but I dunno how lol =D

In my maze there was no ray casting, it's only front plane and side plane sprites, rotated and scaled to create the scene.
That's why it's always a strict frontal perspective with the POV exactly in the middle of the front plane.
Making a wolfenstein-like... hmmm dunno, I saw a 3D plugin for C2 a while ago here...

This page describes how to do ray casting:

Here's a crude implantation:

I have a slow computer so I made the example with a small display.

@Wastrel Thanks.

Here is an improved example with:
* textured walls
* more precise wall/ray intersections
* angled walls

OK, how in the world is this done? We don't have sprite distortions like that!
