You've heard right, I have an Extenstion Package for Game Maker 8.0! It's in .LIB format. You can only use some of the action blocks in the Pro version, for example, the "Rotate Sprite" only can be used in the Pro edition.
There are 3 parts of my Extenstion Package. You can download them at the bottom of this page.
Frequently Asked Questions:
Q: How do I put them to Game Maker?
A: It's easy! All you do is just go to your Game Maker program folder, and then drag the .LIB file into the "lib" folder. After that, open your Game Maker and tada! You now have the Extenstion Package installed into your Game Maker.
Q: The Extenstion Package does not show up. What do I do?
A: If you are in Simple Mode, it will not show up. Only Advanced Mode is required to make the extenstion package show up.
Known Errors:
#1 - (Part 1 error) The "Make Platformer Object" action is (maybe) not working. I might remove it sometime.
