Thanks for the advice concerning the texture sizes. I'll look into modifying the sample.

So, is anyone allowed to use this for their projects?

This is really cool, but I would really like to see it working with some sort of side-scrolling physics.

Feel free to use it for whatever you want except making stupid games like FarmVille, which I hate with all of my being. Of course, if you use it to make a game that makes buzillions of dollars... maybe you can buy me a beer.

I actually developed this sample because the course I'm teaching will have the students modify a side-scrolling space shooter styled game and I needed a way to check for collisions between the ship's image and the terrain's image which will be too irregular to use the simpler bounding box technique.

Unfortunately, I'm not ready to release any of that code because I'm still working out the level loading mechanism which will load and scroll the terrain images.

I've found a little issue with your code, if you don't use rounded numbers like: 1, 2, 3 .. then
y2 can be zero because it get's floored and thus line 144 will give an error saying there's a nil value, I think that if you change math.floor to math.floor(n+0.5) (round the number) then the error will get solved (or maybe math.ceil, I don't know :))

P.S. sorry for the bad English :(
