I want to make a character and his physical model is a box. But it will bounce like a box when the box fall on the ground. Because a character will not fall over, it must be always plumb the ground. So how to make the character plumb the ground and don't make it fall over?
I'm not sure that this is even possible to do with physics like ODE. At least I don't think I ever saw a game that did this but I may be wrong. Most games using characters use approximated physics with simple gravity but nothing more.
