i'm still trying to only animate certain part of a image and i've seen it explained like 2-3 times already but
i really need someone to break it down for me.

i've tried animating only the background and pasting it in my image, but it's never in the exact same position and it's shaky.
how can i make it so its in the exact same part for every frame?
or is their an easier way to animate selected parts?

i use psp7 and AS3

thanks
