Like you can choose if they get targetted by the Aimbot or not and if they are on the radar system.
Like DarkRP jobs? I dont think it's a good idea, each server has a ton of jobs, and it will reset everytime you join another server..
My method of doing it right now is just to compare Team ID's, if they aren't the same as your player then it's an Enemy.
If you want, I can make some hidden feature that lets you whitelist some teams.. or something.
