Ok here is my collision event.
And here is the experience point event.
The damage works fine. The strange thing is, also the experience points work fine, but only when i kill the first enemy, after the second one the exp will be added continiously.
The question is, how to make it just happen one time. Even "trigger once" didnt work, cause the enemy is set to state 11 "dead" and will continiously give exp. So how can i stop it?
