This chapter has been a fast descent from the basic theory of programming and its building blocks into the strata of real code and C# syntax. We've seen good and bad forms of code formatting, learned how to debug information to the Unity console, and created our first variables. C# types, access modifiers, and variable scope weren't far behind, as we worked with member variables in the Inspector and started venturing into the realm of methods and actions.
Methods helped us to understand written instructions in code, but more importantly how to properly harness their power into useful behaviors. Input parameters, return types, and method signatures are all important topics, but the real gift is the potential for new kinds of actions. You're now armed with the two fundamental building blocks of programming; almost everything you'll do from now on is an extension or application of these two concepts.
In the next chapter...
