well one thing i don't get is you're guy can go max, and that will make smooth exceleration, but there is no medium as in you can't keep the speed meter in the middle to make him go a modrate speed or so.
Still i find this system quite intriguing? How did you manage to use his walking anmation bevcause it's never worked when i've done it.
This is definetly the smoothest movement code I've seen. Is there anyway possible you can implement like a cruise control? Or perhaps a more zoomed camera to give off the illusion of higher speeds?
I think its really cool and very well written, I wish you c/would use it for a bullet dodger type game.
