Re: FLASH: Dynamic Magnification demo

[Cheri Harder]

Yes, same setup as mine except my images are MC's not SWF's, but still easy

to change.  And I have two controllers as well.   I did find that the whole

thing has to be pretty well optimized or it gets very jerky.  I had one that

was a "take-apart" object that you could remove pieces of.   It worked well,

but that level of complexity really made it jerky.  Found that you could

improve it a bunch by setting visibility off for those pieces of the

underlying object that weren't under the glass/mask.  Seemed weird that it

would help, but "visibility off" actually makes the object "not exist" so it

doesn't have to be moved around....


So, I still need to play around with my code to get the positioning correct

based on the scale.  I am using scale in the calculations, but my code is

based more on "movement of the dragged object" rather than "position" - so

I'll have to really re-think that one!


Thanks for the hints, Branden! (Oh, and I knew where your zoom control was,

I was asking if you had any positioning code in the zoom control, or if all

was in the drag action)
