PLZ HELP!

for my game I want the zombies to follow my players and attack them for my top-down game. I also have another feature I want so that when players get down, they can’t move until someone comes to revive them.

just don’t confuse them with zombies they are not zombies https://flowlab.io/game/view/1339911

could u maybe be more specific… and i got the follow zombies thing down but i still need help with the player thing where if they run out of health, they get down and they cant move until someone revives them
