Scratch

Well on scratch paint it's really hard to draw something moving, Because you either have to redraw all of it, make it have a very jerky movement, or make the waiting time between the costumes 0.008 or something like that. Making the movement barely noticable. The solution would be making layers. With layers you could start out on layer 1 and draw say a cat sprite.Then you could click a button adding a new layer called layer 2. This would allow you to see the drawing you've already made, but not interfering with the drawing on layer 1.So you could easily trace your cat and make a small change to make the movements flow togther. This would cut down the amount of time it would take to make a your object move, spin, ect. Just a suggestion! :3
