Above image. is to illustrate the four pose walk cycle there are two over lapping legs where one leg at a time supports the whole body and then two striking poses. then to make it a smooth action the inbetweens are drawn. these poses are spaced five frames apart in the video below.
My first play on flash. just got the program and before my taught workshop on monday i thought I'd create a short animation to show the four poses behind a walk cycle. the animation is not smooth because there is only four key frames. repeated. two keys of a stride on opposite legs and two passing leg poses. enjoy
