Once again, to help anyone who might need it, here are some handy tutorial articles I wrote up on using GameMaker, for anyone who needs to brush up on their skills or take a crash course:

1. Leveling Up as a GameMaker dev.  A guide to your progress as you learn the tool.
2. Position and Motion Tutorial.  The basics of moving objects around the room.
3. Wave Motion Tutorial. Getting that nice sine-wave sway.
4. String Handling and Drawing Text.
5. Draw Rich Text. A handy script for more powerful formatting of text  you draw to the screen.
6. Building a GameMaker extension. How to write your GML for reusability, and how to use the GameMaker Extension builder.

And, if you’d like a whole book on GameMaker development, I helped out with editing HTML5 Game Development with GameMaker, ©2013 Jason Elliott, Packt Publishing, and can recommend it as a worthwhile book that will teach you some useful things, particularly the new Box2D Physics engine features.
