Idea for Turrets:
Have Bot player have the base of the turret
Next, mount another AI Bot Player (with another mount slot on it for weapons) that shoots nearby enemies, kinda like radius trigger or something
(If you need SG's code back from v8 you can ask it from me).
Mount Weapon Images to it ( So we can save up model download time ). Then, Put up a wrench *weapon that when you fire it, it selects which you want to build, or stuff like that. It can be easily done throught the server chat by using / commands.
*WEAPON not a tool!
