To make a person walk in alice, you have to put in code that moves the leg limbs or if you want it rrealistic, sway the arms at the same time. A lazy way to do it if to capture three poses: One pose of the person standing still, one with its arms and legs moved one way and the third with the arms and legs in the opposite positions as if they have been flipped from the second pose. Then you can set the poses to change in order like this: 1st pose, 2nd pose, 1st pose, 3rd pose, and then repeat.
Actually moving the limbs with code is a much better way of making the person walk, but using the poses is quicker.
