I have an AI team that works its way through a town checking various locations. The human team provides Sniper overwatch. Currently the AI team holds at a locations until certain enemy groups are killed, it then progresses along its waypoint path. What I would like to do is that if the enemy group is killed, the AI team moves, if 15 mins passes, the team moves on regardless. I kind of have a way to do it in my head, but I can't quite formulate it.
Any help appreciated
