There are a couple of things to check for: 1. Did you remember to attach your behaviors to the enemies/player? 2. Is the player hitting the enemy? If they pass through each other, then in the game center, check your collision groups, in the player, and make sure the actor button is green so they will hit each other. If neither of those two, feel free to send me a screenshot of the behaviors and I can try to help. BTW, I like your avatar :)
