Associate tween to Sprite but don't tween?

Recommended Posts

Hello,

 

I'm new to GSAP and have only begun to use it so this will probably be a pretty simple question. I didn't know what terms to search on, but it's probably been asked in the past.

 

I am using a for loop to create a set of training module display objects (ModuleWindow). They all contain unique content, and they all must start out offscreen, at y=stage.stageHeight+10. When the user clicks a menu button, the appropriate module needs to tween up so it's visible, and whatever one is visible needs to go back down (reverse).

 

All I know how to do at the moment is create a TweenMax instance using .to, and that of course causes the display object to begin tweening immediately. So clearly this won't work:

for (var i:int = 0; i < contentArray.length; i++) {
     var module:ModuleWindow = new ModuleWindow(contentArray[i]);
     addChild(module);
     module.y = stage.stageHeight + 10;
     var moduleTween:TweenMax = TweenMax.to(module, 0.5, {y:10});
}

...because I want each module to stay put until the appropriate button is clicked to bring it up.

 

What I want to do is create a TweenMax instance that I can associate with each module (hopefully by assigning it as a get/set property of the module, such as module.tweenUpDown) and then invoke each module's TweenMax instance whenever I want.

 

How do I do that?

 

Thank you!

Sounds like you can just make the tween a property of the module and create it in a paused state like

 

for (var i:int = 0; i < contentArray.length; i++) {
     var module:ModuleWindow = new ModuleWindow(contentArray[i]);
     addChild(module);
     module.y = stage.stageHeight + 10;
     module.moduleTween = TweenMax.to(module, 0.5, {y:10, paused:true});
}
//later
someModule.moduleTween.play();
//or
someModule.moduleTween.reverse();
