I hope you do it and I just hope you do that function to make a zombie rpg I have functions to make them on the ground and those things but only lack the NPC I hope and do that functions soon :D :D ;)

Too bad we don't have real npcs' functions.
No matter how much you try to make them feel real, they are still moving objects. Im dealing myself with this problem, but it's easier in my case.
