You know how there is a randomize button in the player menu?:Well, why don't you hit it and do the /applyav command?Wrench the spawn, unwrench, type /applyav, then spawn a bot!
I know, but this is a event.
I have to agree with you. I would like to make random bots chase people around. That would be about as crazy as the time when I chased my brother with HUGE clone ducks!
Doesn't the Gamemode_zombie already do this, maybe you could look inside the Server.cs file for your answer.
