Following waypoints in a sequence

Waypoints are often used as a guide to make an autonomously moving NPC follow a path in a general way (but be able to respond with other directional behaviors, such as flee or seek, if predator/prey is sensed nearby). The waypoints are arranged in a sequence, so that when the character reaches or gets close to a waypoint, it will then select the next waypoint in the sequence as the target location to move towards. This recipe demonstrates an Arrow object moving towards a waypoint, and then when it gets close enough, choosing the next waypoint in the sequence as the new target destination. When the last waypoint has been reached, it starts again heading towards the first waypoint.
