Can you change player starting units?

Is there any way to change player starting units?

Preplace them in the editor....

Elaborate on what is troubling you....maybe you want a melee map like situation where each player in the game gets units spawned for him?

I knew that, Its just that whenever they're pre-placed, they show up even if that player's slot is open(no computer or player). I could use triggers, but I would prefer an easier way.

Use Triggers, there is no other way.
