give everyting a name (every playns, every soldier)
And wright this in the trigger activation.
name_1 setDammage 1;name_2 setDammage 1;name_3 setDammage 1;......................
name_1 is the name of one of the soldiers/unit/plain that is going to die when the trigger is activated.
ThatÂ's one way, alot of writing, but it works.
