Defining a method the right way

Just as with variables, we have to let Unity know about a method before we can use it. Depending on who you talk to, some will say "We have to declare a method," others will say "We have to define a method," or even "We have to implement a method." Which is correct? In C#, it doesn't make any difference. Use whichever term helps you learn more easily. I like to say I'm defining a method's code block, nothing like declaring a simple variable on a one-line statement.

The minimum requirements for defining a method

There are three minimum requirements for defining a method:

• The type of information, or data, that a method will return to the place from where it was called
• The name of the method should be followed by a pair of parentheses
• A pair of curly braces should be present to contain the code block:

  returnDataType  NameOfTheMethod ( )
  {
  
  }
