I'm trying to implement a 'Town Guard' feature seen in Oblivion and other classic RPG's: when the player commits a crime (shoplifting, hitting a harmless commuter etc.), a couple of guards soon show up to arrest him. But they don't just appear from thin air, they tail the player starting off from their barracks, so the player has a chance to evade them.
What's the best way to implement this?.. Thanks.
