Lua error in Module:API at line 338: attempt to index local 'class' (a nil value).
In this example, an NPC travels between two points, following paths created by PathfindingService. When following the path, the NPC looks at the Action of the waypoints it is trying to reach. If it encounters a waypoint it cannot get to by walking, the NPC’s Humanoid will be instructed to jump.
This code can be seen in action here. The place is not copy locked.
