We learned a lot in this chapter about the different types of variables and how to use them.
Specifically, we covered:
The different types of variables including ints and floats, strings, vectors, and rotators.
How structs and arrays are created and how to use them.
How to set default properties for variables and use config files.
Common operators used with variables.
The various flow control statements to do different things under different circumstances.
Now that we've learned about variables, we're ready to start learning about the class tree and the commonly used classes in a UDK project. By the end of the next chapter we will be running our own custom game!
