Controlling and Choosing Positions

In this chapter, we will introduce a few recipes and demonstrate a selection of approaches to character control, spawn points, and checkpoints. In the next chapter, we’ll look at waypoints for AI-controlled characters traversing Unity navigation meshes.

For example, objects follow the path of a waypoint, or seek (move toward) or flee (away) from the current position of a character.
