For a walk cycle to work a walk one walk cycle would be made and then looped.
Animators work on the legs and then the body and arms afterwards in a walk cycle.
We move up and down in a wave like line that the head flows though when we walk.
The starting position is called contact of a walk cycle is the foot closest to the “camera” having contact with the ground.
The second frame is the down point will be the figure having full contact with the ground and the back leg being raised.
The third frame is known as passing
The fourth frame is the up
The fifth frame is contact again.
When animating a walk cycle from the front the up and down frames should be done first.
When animating a walk cycle from the side the contact and passing is drawn first.
Animators used a lot of walk cycles references
