I wish to use UTE at the server side.

Requirement:
I will have dynamic user data with which I will be creating animation frames in a batch. Those animation frames I will be using to create videos.

Current Problem
I am using LIBGDX which renders the frame on the screen and I am able to see the Window Frame. I don't want that frame to come up instead it should be an Headless Application just generating the frames in the file systems.

Anyone can help me accomplish this?

I'm using Google PlayN(Java)

(1) Am I creating the timelines correctly? all of my timelines are generally created this way.
//****************************************************************************************************************
public static Timeline doSexyZoomScaleIn(ImageLayerContainerLocal ilc,float delay){
Timeline animationTimeline = Timeline.createParallel().beginParallel()
.push(Tween.from(ilc, TweenEngineAccessorContainer.SCALE, 400.0f).target(5f, 5f).ease(TweenEquations.easeOutBack))
.push(Tween.to(ilc, TweenEngineAccessorContainer.ALPHA, 200).target(0.4f).ease(TweenEquations.easeOutBack))
.end();
return animationTimeline;
}
//********************************************************************************************************

(2) I see you have a fix for this bug 2 years ago, and switching to 6.3.3 really made a big difference in the frequency the issues occurs but It did not stop it. Is it something I'm doing that may cause the issue to occur?

I'm also attaching callbacks so I can trigger events in my app. any insight will be greatly appreciated, even if it to point me to where the timelines are managed in the api and I'll try fixing it myself(I have tried).

Hey,

I am running into a pretty weird problem: I have two TweenAccessors that handle totally different classes and that live inside two different classes as well. But when I create tweens for both accessors at the same time, it happens that the values seem to intersect.

My specific example looks like this (I'm working with LibGDX):

• My AnswersSelection actor has 4 sprites that are being modified by a SpriteAccessor. It scales the buttons up (to 1.f) on .show() and fades them out on .hide(). This works fine.
• My QuestionTitle actor has a PositionOffsetAccessor (with x,y values) which modifies a custom PositionOffset object. The actor creates a new tween that animates the PositionOffset to (0,0) on .show and animates the offset to (0, 150) on .hide().

Now, if I animate both Accessors at the same time, it looks like they are intersecting. One of the buttons suddenly has a default scaleY of 150.f and scales down to 1.f which totally distorts everything.

I hope you get what I'm trying to explain and I hope you can help me.

I've posted a question on stackoverflow.

Is it possible to end a tween before killing it?

Please add maven support

The demo site mentioned in the readme ( http://www.aurelienribon.com/universal-tween-engine/gwt/demo.html ) redirects to the main website.

What is the correct way of creating custom easings like you can in GSAP? It seems the library has been prepared for it as for example there is a param_s in the BACK equation class and it has a method which can set it.

public Back s(float s) {
    param_s = s;
    return this;
}

However when instantiating it, I get a 'Non-static method s(float) cannot be referenced from a static context' error.

private Back customBack = Back.s(.5f);

Tried with and without the new keyword.
