Tracking a Target

I'm trying to get my "Bots" to chase their targets over a terrain. The thing is, I cant just use point entity, because I want the bots to utilize the same control system/characteristics as the real players. So I pass messages to the control system to bank left or right. Here-in lies the problem. How to determine which direction my bot should turn. I thought I could use TFormVector, but it isn't working so well for me. Basicly, I just need to know if the bot's target is to the right, left, or behind the bot on an x,z grid. Any ideas?

Ahh.. Nevermind.. Figured out another way to do it.
