[transformMatrix3D Plugin]

hi,

 

i need to tween the scale of an image, which simple to do via the scaleX/Y properties. However due to performance (iOS) i wish to examine using the transform.matrix3D which enables the gpu. The transformMatrix works as expected yet just not hardware accelerated.

 

TweenMax.to(imgInstance, 0.3, {transformMatrix:{scaleX:scale, scaleY:scale}});

unfortunately i cannot find much on tweening 3Dmatrix properties. How would you do it?

 

I did found reference to QuaternationPlugin but documentation on that subject is scarse and I am unsure on how to proceed with that (is it even possible to scale, with that?)

 

Would it be difficult to add such a plugin by modifying a copy of transformMatrixPlugin?

TweenMax.to(imgInstance, 0.3, {transformMatrix3D:{scaleX:scale, scaleY:scale}});

 

any insight/hint/code would be very much appreciated, thanks

[TweenMaxVars.startAt bug [SOLVED]]

cool - thanks - however

 

i still get an exception, it seems because vars is an instance of TweenMaxVars

 

ReferenceError: Error #1037: Cannot assign to a method overwrite on com.greensock.data.TweenMaxVars.

which originates from in TweenMax.as

override protected function init():void {
		if (this.vars.startAt) {
			this.vars.startAt.overwrite = 0;

 

my suggested patch was to extract the anonymous vars object from the TweenMaxVars instance before calling the _set method... That solves it, but perhaps it could be done differently...

 

suggested change (works for me):

public function startAt(vars:TweenMaxVars):TweenMaxVars {
return _set("startAt", vars);
}

to

public function startAt(vars:TweenMaxVars):TweenMaxVars {
return _set("startAt", vars.vars);
}

[TweenMaxVars.startAt bug [SOLVED]]

hi i found a possible bug with TweenMaxVars (version 5.1) and the startAt method. The generated object in the vars property contains a repeatDelay property while utilizing the startAt method, not - as one would expect - an startAt property.

 

consider the following

 

vars = new TweenMaxVars().prop('z', 0).startAt(new TweenMaxVars().prop('z', -200)).vars;
trace(ObjectUtil.toString(vars));

(Object)#0
 repeatDelay = (com.greensock.data::TweenMaxVars)#1
   isGSVars = true
   vars = (Object)#2
     z = -200
 z = 0

 

change in data.TweenMaxVars

public function startAt(vars:TweenMaxVars):TweenMaxVars {
    return _set("repeatDelay", vars);
}

to

public function startAt(vars:TweenMaxVars):TweenMaxVars {
    return _set("startAt", vars.vars);
}

and the vars object is what is expected

trace(ObjectUtil.toString(vars));
(String) = (Object)#0
 startAt = (Object)#1
   z = -200
 z = 0

top thanks! works...

[Timeline issue - second tween not playing]

I did not mean to do bad form especially on my first post. my apologies...

 

"Could someone please confirm this is a problem or not?" wasn't an invitation then?

 

recreating the timeline does work fine. For this iOS project I try to reuse as much objects as possible (object pooling) that was why I choose this route. I also kind of like the idea of creating several timelines as 'behaviors' and trigger them when needed... My reason for posting here is that this seems like a bug to me. The invalidate method doesn't correctly invalidate... But perhaps it is just a side effect of the way the timeline works and is it not intended by design for what i want. I you agree i would like to hear about it someday...

 

anyway thanks! I love the library!

[Timeline issue - second tween not playing]

I seem to have a similar problem

 

I have are three tweens in a timeline (zoom in, rotate, zoom out). I create this timeline once per object and would ideally 'rewind' and play it every time. According to the documentation I need to use myTimeline.invalidate() and myTimeline.restart(). I think I understand why that is, however something goes wrong with the relative rotationY value in the seconds tween.

 

The point is that the third animation only runs once. A second time it gets skipped, but the sprite IS set to it z=0 position... When i change the rotationY value to be relatively changed the animation runs flawless (but i need it to run relative to it value) every time.

 

Any pointers would be appreciated.
