WARNING: This project does lead to scratch crashing. This is an example of a bug report i have made on the forum. I have found an extremely odd bug where using this specific script the text javascript on the page hangs for some odd reason, leading the tab to completely crash. If you dont put a negative number into the if statement when checking the x position, scratch appears to be fine. my guess is creating a new clone while having a clone is something scratch doesn't like.
