what It's like and how to animate a stickman running around and jumping around an obstacle course. •select a pen size, and start drawing. •select the onion skin option located under the keyframe list if you want to see a transparent image of the previous layer(s). •press F7 to make a new keyframe, or F6 to copy the keyframe to the next. •press enter to see a preview of the animation.
