Programming is a vast and versatile field, and while mastering the profession may takes years, the basic concepts are simple enough to pick up and utilize.

The primary components that will make up your programs are:

• Comments
• Variables
• Functions
  
• Expressions
• Statements

This tutorial will teach you what the above are, and how you can use them to write your own scripts and programs, and soon enough, your MMORPG.

An important concept to understand before even starting this tutorial is that code is placed within "Execute Code" actions. When an event is triggered, the instructions you've written within the code block are executed. Review our Introduction to Game Maker tutorial before continuing if that doesn't make sense to you.
