[DeathCloaker 0]

So i was trying to figure how ai troops when in the radius of a  trigger the trigger activates the hint and my way point as squad leader. it weird it only works for the player that is the radius of the trigger which I know but im trying to know its possible for ai in the radius of the trigger to activate not just only for the player.
