[GSAP in Flash Canvas - Null Target Error on Masks]

Thanks Carl. We ended up just dropping out the masks for now. But I'll check with CreateJS for future attempts.

No, and a new error message:

 

Uncaught TypeError: Cannot set property 'y' of undefined.

 

It doesn't seem to recognize the movieclip instance. The movieclip holds a vector shape, which is the mask. This is a file that I converted from Flash AS3/Greensock to a HTML5 Canvas doc, if that matters.

[GSAP in Flash Canvas - Null Target Error on Masks]

Hi All,

 

I am trying to animate a mask in a Flash HTML5 Canvas document using TweenLite. I am trying to animate a symbol that is in a mask layer. But when I try I get a JavaScript console error:

 

TweenLite.min.js:12 Uncaught Cannot tween a null target.

 

My other objects animate fine. I believe I have all the proper .js files loaded in the HTML (easelJS, tweenJS, movieclip, preloadJS) and the Tweenlite files (CSSPlugin, EasePack, Tweenlite). 

 

Here is the code I used that throws the error. 

TweenLite.to(this.leftYellowStripeMask, .5, {y:-9, ease:Quad.easeOut, delay:.3});

I'm guessing masks are not supported this way?

 

Thanks,
