Gcombat ballistic computer help

Hi, ive got gcombat and ive noticed that there is somthing called the ballistic computer. to make it work you put in a targets distance and the projectile violocity and it out puts and angle. what i dont no is how to make that into a artillery cannon. if anyone could tell me i would be very happy.

I’m not very good with wire (too busy with LUA and mapping to learn wire) but from what I’ve gathered about it, use a target locator to guide missles with wire. I’d guess its the gps but like I said before, idk.
