eem to be my only other choices. How can I specify that even-number “strength” property of Sine easing in the code?

Hi Jen,
I really like the ability to ease a property “there and back” by using Sine easing and setting the strength to an even number. Is there a way to do this in AS3 code rather than through the motion editor? I’ve tried it this way:

tweenRotX = new Tween(targetSprite, “rotationX”, Sine.easeIn, 0, 90, 20);

The result is that it tweens rotationX from 0 to 90, instead of 0 to 90 and back to 0. Results are similar if I use “Sine.easeOut” or “Sine.easeInOut”, which seem to be my only other choices. How can I specify that even-number “strength” property of Sine easing in the code?

PS: I know it’s possible to do it in the motion editor first, then “copy motion as AS3″. That would make sense for truly custom easing or for a complex tween of several properties at once, but I’m only tweening one property here, in a way that doesn’t seem to be outside the normal capabilities of the Sine class. So if there’s a way to do it without resorting to “copy motion as AS3″ (and the resulting AnimFactory code that I don’t understand) please let me know.

@MC: Yep. What’s happening is the instance you have selected is auto-keyframing at the location, thus creating the tween. It’s telling the tween “at frame XX, tween to this size”. While that’s useful for creating tweens and makes them so easy now, but you have to accommodate for it if you want to modify the entire instance.

First of all, if necessary, you can remove any tween you have already for scale that you don’t want - go to the Motion Editor, and click the Reset button in the Transformation row (it looks like a blue round arrow). Or, you can delete the keyframes in the Scale X/Y rows. Make sure all the keyframes are gone (except for the first, which you can’t remove anyway).

And to change the scale (or any property) for an entire tween, you just want to make sure you make the change on the first frame of the tween. So just move the playhead there, and make the modification - no tween will be created, and every frame of the tween will be the same.

Now I will note that you do need to make sure that you don’t have any keyframes later in the span for that particular property, or you will end up tweening between the new value on frame 1, and whatever keyframe is later in the span (this is no different than any other tweening though, so should make sense :)

Hope that helps!

I have a question about scaling in regards to the new tweens. I have a tween that I created while the symbol was at 2x scale just to make things easier to see (I should have zoomed). Now I want to scale it back to the size I want but I am struggling to get anything to work.

I don’t want to change the scale property on a frame within the tween, I want to globally scale every size property so that the tween looks exactly the same, just smaller. I can not figure out how to do this, using the scaling tools in the usual manner does not appear to work and always changes the scale property on a frame of the tween.

Anyone know?

Cool, thank you. I spoke with John Mayhew briefly at Flash Camp. I was planning on checking in with him this week. At this point, I’m looking for a way to access/create an object tween. Any kind of access to an armature would be cool too.

Cool, love to hear that! Well, this blog represents the Motion part of the Flash team (I’m the Motion QA), so let us know if we can help.

Thanks, Jen! I’m hoping to stay in contact with members of the Flash team to get at some possible undocumented features as well. I’ve got several (motion-specific) CS4 extension ideas at the moment, but they’re not all available in the documented JSFL. I’ll keep you updated on any progress.

Hey Justin! Wow - that is a GREAT extension! I know I’ll be using that one a lot. I really dug the text extension you built too (and voted for it in the judging room). Love that you’re building really useful tools for Flash - and even love it more that you did one for motion :)

Hi, I was at Flash Camp this weekend, but I missed a lot of the sessions while I was working on my hackathon projects. So I’m really grateful that you put this content online. I love the ability to save and reapply a Motion Preset. I decided to create an extension to generate a live preview for a custom preset:

I’m loving the Flashthusiast content and I’m looking forward to seeing more. Thanks!
