Also, I'm trying to code in customization of the controls, and I tried to do this by having strings like key_forw, for moving forward. Then I set the string to "key_w," and whenever key_forw was needed, I used engine_getscript(_chr(key_forw)), which, if I understand correctly, is supposed to use the contents of the string as code. This didn't work, so how should I accomplish this? Thank you!

However, I would use something different since calling engine_getscript() every keystroke is probably pretty slow. Shitlord by trade and passion. Graphics programmer at Laminar Research.
