I figured out how to make scrolling with no variables. This way of scrolling uses very little math, and in fact the only math is greater than and less than (and the and block, but that's not really math). Please use this in your games, but if you do please give me credit. This uses two terrains, but you can make as many as you want as long as you just copy the script from one of the others and make a few changes. You can also make the cat move faster, but again you would need to make changes in the scripts. This only uses three sprites and three scripts, but please remix and give me a link if you can make it any simpler, or you can just post a comment. Thank you.
