Currently, this targeting formula works for simple robots 90% of the time. It's rubbish against most advanced robots. Feel free to improve/comment on it so I can learn (since tutorials are utterly useless on me, I need visual aids).

GITS Targeting (Source) - from version 0.5-051509


I took down the source because I'm going to rewrite the GhostGun using classes to extend the plug-ability. I will post that when I get a (most likely horrible) working version.
