Trigger Request

[Shamwow]

I need a trigger for a 3rd person camera that follows behind the character even when you turn, what i have is a hero selection system were you pick your hero with a wisp...and i need the camera to switch to the unit that is picked were i have it spawn which is at a diffrent section of the map so if someone could show me a trigger like that or tell me how to find one or make one that would be awsome....
