Walking?
 

As a beginning Alice programmer, I recently completed an assignment for my class where I had a mummy slowly creep towards a Pharaoh.

Now my question is, how can I make a person walk in a way that looks reasonably looks like real walking?

Most "people" models have a pre-written "walk" method, and all you need to do is call it. If you have a model that has one, use it, but if it doesn't, then find a model that does, and alter the code some, and you should be good! (This is not a very good answer, and I know that, but I am too lazy to research it right now. At least it will help a little.)
