We will write a script called Path.cs and store all the waypoint positions in a Vector3 array. Then, from the editor, we will enter those positions manually. It's a bit of a tedious process right now, but we don't want to make things too complicated. Fortunately, since the number of waypoints that we are creating here is not that substantial, the operation should not take too much time: ...
