Zoom & Pan

Question

I have a new project at work that I want to improve the interactivity on. Let's say I have a country map with icon-buttons representing cities.

Click on a button, and you zoom in and pan across to that city, close up. (Not unlike searching on Google maps.) A talkbox of information appears, including a X close button, which would return you to the zoomed out and centered state or position.

How can I do this?

I imagined using different MC's, placed on frames across the timeline. Click on a button, go to frame _ and play the MC. The MC would include the zoom in and pan (transform scale and position).

But what if I could use Flash "math" to zoom directly into the city, not MC involved? How do I script that?

Anyone?

Thanks so much.

i think that would be easier and more satisfactory to use code instead of timeline frames. each city could be a child movieclip (transparent works, too) of the main map parent.

when a you want to zoom and/or pan to a city, you would determine how much its x and y need to change to center it on-stage. you would then apply that transform to its parent map.
