I haven't started doing it but it will be part of my idea.

-Climbing like in Parkour  or like some martial artist also do. 
-Walking up stairs or walking down.

With climbing for example..sure i can just move the character but that won't look good. How would i animate Force? To have a realistic character pushing himself up a wall would require animating the muscles so that they look like they're vibrating as they exert force. This is difficult.

thanks
