As I said on another thread, this looks hot. I hope the staff plans on adding slope physics. Let me explain what I mean by that.
1. In the classic series, Sonic's jump was relative to the slope, not just gravity. If Sonic was moving up a slope, he could jump higher and yet his horizontal movement was practically halted. Sonic's jump while moving down a slope made less vertical distance, but he was moving forward at almost full speed.
2. Rolling down a hill. Pretty standard idea, should only take a simple formula to get it to work, I would think.
3. Running up and down a slope. Sonic could run up a slope, but he'd eventually slow to a stope. While moving down a slope, he'd just keep getting faster and faster. Sonic probably won't be able to maintain a speed higher than his maxspeed in SRB2, but those physics still should be set in place.
Thotts?
