Vizzy question

This video explains it quite well. I personally use another script, so I didn‘t test his script, but I can‘t find the video for my script anymore. If you just want to copy my script (not created by myself though) you can find it in my Starship vizzy.

Try downloading this craft and reverse-engineering the code. I haven't done this sort of stuff before, so this link is the only thing I could think of.
