This model is free and offers many animations. So get that and lets make anew scene. If you are using Unity 5 you want to go to the prefab and under Animation change it to 'Legacy'. When the dialogue box pops up click "Apply".
First we have to set the scene: our skeleton will need a character controller and a camera.All i did was add a character controller component to the skeleton, set the the Y value 0.7 and holding down the shift key i adjusted the width of the collider using the little green squares on the collider. Make sure that under the Animation component Play Automatically is unchecked.
horizontalX = Input.GetAxis("Horizontal");
verticalY = Input.GetAxis("Vertical");
