Hi guys, I've made my own crab scenario but I've a problem. When my crab eats a burger, he's supposed to enter in a "godMode" for 5 seconds and he's supposed to be able to eat Lobsters during that time.
But in fact when he eats a burger he can't be eaten by Lobsters but he can't eat them, I don't know why.
Here's my code:
Thank you for helping me :)
