Automatic footstep creation is the easiest way to create a walk or run cycle. You can use this method to make the biped climb or descend a flight of stairs, hop repeatedly, and do a variety of motions. Automatic footstep creation places the footsteps for you, generating perfectly timed and spaced footsteps.
To create footsteps automatically:
You are now in Footstep mode, where you can create, activate, or edit footsteps.
The selected gait determines the timing pattern of the automatically placed footsteps.
The Create Multiple Footsteps dialog appears. This dialog determines various aspects of the footstep sequence, such as how far each footstep will be placed from the previous footstep.
This places footstep icons in the scene. To make the biped move through the footsteps, you must create keys for the footsteps.
