Not sure if you posted on the correct forum either

Are you using Dark Physics or want to implement character movement in general?
Easiest way in Dark Physics is to have a physics "character controller" that you hide and position your model on the character controllers coordinates.
If you don't need physics, use Cloggys collision plugin (
http://forum.thegamecreators.com/?m=forum_view&t=74762&b=5 it has some very nice example code) the method is similar here, you hide the object used for environment collisions and position a model on it's coordinates.
Forget about the model for a while and look in to the character movement code first, just get a box or sphere moving and interacting with some other boxes or a plane as a floor, then when you have it working add the model and animations.
