The first thing I would do is build my noob model. After that, I would make whatever the noob is going to come out of. To get the noob to spawn I would use :clone. Then I would use Roblox’s pathfinding service (Character Pathfinding) or SimplePath (SimplePath - Pathfinding Module) Then I would check if one of the noobs touched the AI building and remove 1 point of health. With this, though you might want to do a remote event so that way it syncs with the server overall just better if you are gonna use datastores or updating for all players.
