The Way of the Waypoint - YouTube

In this tutorial we will be adding a way system to an existing scene. Way systems are made up of two parts: Way borders and Way points. Way borders are a set of lines that the player character can't cross. This can be used to define an area that the player can walk within or an area that they are prevented from entering. Way points, on the other hand, are points that act as landmarks within the scene. How those points are connected together will act as a path that guides the player character around obstacles within the scene.
