With great sandwich comes great responsibility

There are a few rules and best practices to follow when declaring functions. They are as follows:

• Your function name should start with a capital letter.

• You must never start a function with a number or some weirdo character like the Rod of Asclepius or you will get an error. An error is a written notice that Unity sends you when something you typed doesn't work or doesn't make sense.

• You can press the Enter key to drop the top sandwich bun down a line. Some programmers (like me) prefer writing code this way so that they can see the open or closed sandwich buns lined up, but other programmers prefer code that doesn't spread out too much.

  

In this book, we'll use both approaches just to keep you on your toes.
