Hey,

I’ve already figured why its not showing. Its seems that you just have to register the conversion of the movie clip symbol to top left and not center. Anyway, thanks for this review! Hopefully i could come up with something great with this! Peace!

Yow,

I’m new here today. i hope you could still reply. I’m reviewing your example 3 and practicing it. I’m trying to use Oval shapes but i can’t seem to show the whole circle when i place this code:

“var dt:DistortionTweener = new DistortionTweener(c, oval_mc1, new Point(0, 0), new Point(oval_mc1.width, 0), new Point(oval_mc1.width, oval_mc1.height), new Point(0, oval_mc1.height), 5);”

whenever i do this without continuing the remaining bottom parts of the script it seems to show only 1/4 of the whole object(from center of the oval to bottom right). I’m not really sure if there should be a change on the x and y axis, i’ve tried but it seems to distort it way to much and still shows 1/4 of the whole oval.

Do you think its possible to Distort Ovals? if it is what should i change to show the whole oval?

ooops. i’m sorry the holder of cource need to be at least a DisplayObjectContainer for the addchild method. stupid me.

hi there,

great class. i just been think that you could replace the type of both the holder and the mc by DisplayObject. there is no need for a MovieClip, and the holder has to be a DisplayObject. anyways thanks for your effort, i will definitely use this class in upcoming projects.

cheers, jan

Kristian,
Sure, before calling the tweenTo method just set your delay or call tweenTo anywhere you want it to happen in your code.

Hi.

i`m kinda new to this, But is it possible to add a delay beefore the animation starts..?

Evan,
I think something to look into which would maybe give you a similar effect (or something close) would be perlin noise and applying it to the movie clip you want to distort. Unfortunately I don’t know off the top of my head how exactly youd go about it but if you play with it you may be able to get something close.

Have you downloaded and looked at Grant Skinner’s file? I didn’t but I’d imagine you could probably repurpose that somehow. Grant is a great coder so I’m sure you could go off of his files or maybe even ask him for some help.

Thanks for your prompt reply Matt and your generous contribution of Distortion Tweener to actionscripters. Your answer was a surprise to me as I had expected you to say that Mac style effect was doable but I definitely take your word for it.

I was hoping to have a Mac OS style “swoosh” transition effect for a little app I’m working on using the Distort Image or DistortionTweener but I now know better. I had thought that maybe DistortImage could do the trick with different easing and/or tweening values for top-r/l and bottomr/l at different rates but I have been saved a lot of frustration and time by knowing now that it is not doable.

The other displacement map way of doing it I found was too processor intensive on slower computers (even in AS3).

In your estimation, would the something similar way of doing it with Distortion Tweener be as spectacular? What kind of even more spectacular slide transitions could be developed with Distortion Tweener then?

Hey Evan,
Unfortunately you can’t achieve that effect with it. You can get something similar (because the distortion is only applied to four points) but not that exact thing. You can use it to distort it into a trapezoidal shape and then tween the two top points out to form a rectangle, but thats about it.

Hi Matt,

Can distortionTweener be used to recreate the Mac style squeeze transition as displayed here:

http://www.gskinner.com/blog/archives/2007/11/squeeze_effect.html

If so how? I’ve been trying at it but can’t get it. Seems like easing for the top and bottom parts of the the slide are different in the osx style transition. And I don’t think two distortionTweens can be applied to the same mc at the same time.

Is this effect possible with DistortionTweener or DistortImage classes?
