This question is probably stupid but im new here.
So here is the problem:
I want to make RPG map. The Hero is Goliath and..... well this is not inportant.
I want to make trigger that activates when Hero kill specific unit. It should give him money (minerals). I tryed to make condition like this: Player 1 kils at least 1 Zerg Ultralisk.
Actions were like this: Add Player 1 500 minerals (or something like this); Preserve trigger.
Result: Hero kills Ultralisk and gets 500 minerals, but it get 500 more and 500 more....
Can you help me make trigger right?
