The main focus of this chapter was learning about
NodePaths, where they come from, and what we can do with them.
Specifically, we covered:
NodePathsto play around with. We used
loader.loadModelto bring our track and, later, two cycles into the scene.
NodePathswith the position, rotation, and scale methods. We also learned about how each
NodePathhas its own coordinate system, and how parent child relationships affect that.
