Defining a method properly

Just like for 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. Which is correct? In C#, it doesn't make any difference. Use which ever term helps you learn easier. 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, a method will return to the place where the method was called
• The name of the method should be followed by a pair of parentheses
• A pair of curly braces should be present for containing the code block:

  returnDataType   NameOfTheMethod ( )
  {
  }

Looking at LearningScript once again, or any Unity generated script, the Start() method has the three bare-bone minimum requirements for a method:

void Start ()
{...
