Hi Lex,

I see it has been a while since the last post. I have just downloaded your AS2 version, all working fine thanks. I see there were a few posts re adding Zoom functionality. My knowledge on AS is limited, so would not really no where to start. You may have already created something along these lines or no where I can get more help. Please advise.

Thanks.

I responded to your question at kirupa (see here) as well as provided (or tried to) an explanatory FLA showing how scrollRect responds to a scaled clip. Hopefully that helps get you on the right track.

Great class! I’m trying to add zoom functionality to this for a project I’m working on, and have run into a small issue. I want to keep the viewable area locked when zooming, and only affect the mc, however, even with setting dimensions for the _rectangle, and defining the aperture width and height as the same, when I scale mc, I get a scale for the viewing window as well. Any ideas?

HI Ricardo—my classes aren’t set up for that type of functionality. You’d have to dig into the AutoPan Class and add that type of functionality. Basically, the _aw and _ah (aperture width and height) properties would need to be set to the stage.stageWidth stage.stageHeight. But you’d also have to set the width and height of the _rectangle object that is use for the scrollRect. And lastly, set _clip.scrollRect = _rectangle; Hope this helps lead you in the right direction.

Theres a way to use it relaative to the Stage width and height, replacing the visibleWidth and visibleHeight with onResize handler?

Tanks in advance

Hi, I’m new to as3. It seems than you have used flash cs4 to create this. I’m trying to use it in a project I’m working on. If I save the file to cs3 and reopen it and publish an error message appears: 1046: Type was not found or was not a compile-time constant: MovieClip.
Do you know what should I fix to make it work again? Thanks

Hi Lex,

Thanks for the code! I am trying to invoke the public methods, stopMotion(),etc. to buttons within the mc instance.

My goal was to stop the panning when I click on the thumbnail that creates the child and then return to panning when I close the child.

I have tried things like this.parent.stopMotion() and MovieClip(this.parent).stopMotion()
I get various errors.

TypeError: Error #1034: Type Coercion failed: cannot convert com.lextalkington.autopan::AutoPanDocument@3d102681 to flash.display.MovieClip.

1061: Call to a possibly undefined method stopMotion through a reference with static type flash.display:DisplayObjectContainer.

Lex, phenominal class.

A world of help and just exactly the type of effect I was looking for.

Thanks so much.

@Chris – You should be able to play with this line within the constructor:

1	_easeSlideTo = ease*0.5;

The easing value you pass into the constructor is cut in half there – if you change 0.5 to something else, you’ll have some control over the speed. Hope this helps!

Fantastic class! Any way to control the speed of the slideToPoint function?

I reposted the AS2 version - however, it has a few bugs, mainly the one FireFox bug that has been repaired in the AS3 version - so you may have to deal with that, but you can download the AS2 version here

Hi there!

Really cool panning tool. Do you possibly still have the AS2 version somewhere?

Thanks
