So I made a game that has a character that shoots zombies. The zombies spawn because of a triggered timer; so whenever the timer triggers a zombie spawns. I need the zombies to die after they get shot, I set a collision system, however, I can only shoot one the zombies and the rest don't get killed.
Here is my code...
