    Okay, so the problem is that I want Sonic to curl into a ball after shooting off ramps.

    Is there a way to make this happen?

    (using Hivebrain 2005 disassembly)

    I'd assume so. The Sonic object's status variable has a bit which tracks whether Sonic's in the air or not. If you track down where that bit is set, you should find the code that runs when Sonic leaves the ground. From there, you can set the bit that indicates Sonic's in a ball, and change his animation to the curled one.

    Okay, so I found that there's a couple lines that tell sonic to change his animation frames from vertical running to horizontal after exiting ramps, I think if I could add a invincibility tick and change the line that loads the animation to play the roll animation it might work.

    Actually, no.
    The game is programmed like that so as soon as Sonic uses the rolling animation, he automatically gets its properties as well.

    You can add some code in ObjectFall that checks if the object is Sonic (which can be done with cmpi.b #1,(a0)) and then if so, change to his falling animation. If you want it to be only when going off ramps, you will need check if his angle is greater than a certain value and less than the opposite of that value.
