Summary

We learned a lot in this chapter about the class tree.

Specifically, we covered:

• What classes are and how the game uses them

• What inheritance means and how to change inherited variables and functions

• Using function overriding to change a subclass' behavior

• Casting actor variables to use a subclass' functions and tell subclasses apart

Now that we've learned about how classes relate to each other in the class tree, we're ready to start learning more about classes themselves and expand our game's arsenal of classes to give us more functionality.
