I have started messing around with the engine and I have some things I would like to change to fit my needs but don't know how. Question 1: I would like to replace the spindash with a super peel-out like move,I have already changed the animations, I just need to figure out how to get Sonic to run after letting go of the buttons instead of rolling. Question 2: Like most people know, when running, if you press down you start rolling. I would like to remove that. I tried deleting the 'rolling' part out of the events but that doesn't work. All help is appreciated, Can anyone figure out my problems?
