Thanks for the help

Apologies for the (somewhat)vague thread title but, how do you code in KH2 Drive Form esque transformations? I have this KH2 Sora that I've heavily edited, and I want to make this Sora as faithful to the original game as possible. To do this, I have to attempt to make the aforementioned Drive Forms. The raw Sora files already had Drive Forms(Both Wisdom and Limit) implemented, but they lasted for as long as you wanted once transformed, unlike the game which gave you a limited time to be in these forms(Hence the reason why I made this thread). So with all that said, do any of you know of any ways on how to help me with this?(I can give you the files to my Sora if need be.)
