@Duta, thanks for the suggestion! I understand what you are saying. I started working on this a while ago, but only got as far as the file reader. When I got back to it, I COMPLETELY forgot that the file reader actually divided my code up into the proper chunks for me! This made everything vastly more complicated and I used the substrings and such just so I could follow along. I will edit my code to create the vertices and such using these smaller lines. I will not be copying your code directly, but thank you very much for the idea.

Thanks for the encouragement Gamemaniac. You guys are creating actual, refined games, while all I am doing is making very small demos. However, I do hope to realize a 3d first person shooter with this. I am distracted by school and android right now, summer is only about two months away and when that hits, I'll do way more Greenfoot.

There is a bug: on the final scene, you can't shoot towards the far left part of the screen, leaving the troopers almost invincible.

Very nice. This is what I was referring to when I recommended you draw polygons instead of squares. I wasn't referring to raycasting (which is entirely different) but merely suggesting you draw each vector as a polygon. It looks very smooth this way.
