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). | Currently, this targeting formula works for simple robots 90% of the time.
