Additional Info
There are three examples in this .gmk: one that shows how to draw a sprite, tiled, across the entire room, one showing how to draw an array, and one showing how to create, then draw the created array.
Code is pretty well commented.


If you see any flaws, please point them out!
If you have any trouble, PM me and I'll try to get to you with that.
Suggestions for another example? Leave a post here.

Thanks!

Very useful to a new GML programmer. I would just add some more practical uses to using a for loop. Such as looping through a data structure, or show how to do a 2d array with a nested for loop.

Edit: just noticed you DID do a nested for loop. Sorry.

Yes, hehe. Thanks for the kind words.

The problem is, I don't want to create a data structure. XD

if you can make a for-loop in gmk can you make a while-loop?

Yup. While-loops are very simple.

while (statement-is-true) {
  //run some code
}

Careful, they will freeze up your game if you don't use it very well.
