Runs over 3000 pixels, impossible Scratch. So I added a script that teaches over 40 sprites how to "frame-skip" [number of sprites]% faster. As if there were more if you added more, you would cause lag. One by one, I counted exactly how many sprites there should be to make it faster. Why aren't "Random Landscape Generator" creators so lazy to make over 40 sprites for there INSTANT landscape generator? Well, once I can calculate the sprite number, you will be able to make INSTANT NON-LAG RANDOM LANDSCAPE GENERATORS! So (i'm in it too, so give credit) you NEVER have to wait testing your games, players playing your games, & more to get featured, and sorry about the bad picture. But, this is the FIRST one ever! So I am pretty sure this will get featured, and you can use it too! But like a said, give credit!
