I looked around Google, but I can't find anything for this. I wanna be able to spawn a character/creature, do stuff to it, and then turn the AI on and watch hilarity ensue. Can I do this? This is GMod 10, btw.
its built into the interface of Garrys mod! hold down the menu button * i think the default is Q *> on the right side find "NPC spawn"> you can spawn NPC from there and toggle ai_disable on and off from there with a nice little clickable button.
