I see. Ok thanks. I have a couple of suggestions, if you don't mind. First off, it would be cool to ignore any "-" named morphs. I added this on line to do that: if Name == "-": continue Second, it looks like the HandleMoves method is using the wrong names for "Xacc", "Yacc" and "Zacc". I got a script error (but not consistently). I found that you use "XAcc", "YAcc" and "ZAcc" elsewhere, and when I changed the case for those variables in just that method, the error went away.
