boy,… i hate posting on here so often… and actually this is still related to my last question. just a different approach that I’m unsure of.

So… i’ve made two scrollbars… one on the right and one on bottom… horiz, and vert… that scroll a main movieclip that is big, about 2800px wide by 2000 tall…

BUT… I’m don’t know how to update the scroll bars if I were to tween the main clip to a position not using the scrollbars… like if i had a navigation button, that tells the main clip to move to a certain x, y position…

i suppose i need a public function in the scroll bar class that tells it to adjust the track buttons accordingly on the nav event…

well once again, any pointers would be appreciated. thanks a lot.
