I am trying to animate the mask_mc from left to right using TimelineMax. I need a simple setup to set the position then move it across. Help is greatly appreciated. var mask_mc = this.mask_mc; var maskedContent = this.maskedContent; //AlphaGradientMask maskedContent.filters = [ new createjs.AlphaMaskFilter(mask_mc.cacheCanvas) ]; maskedContent.updateCache(); // create timeline var tl = new TimelineMax(); tl.to(mask_mc.getChildAt(0), 3,{x:400, onUpdate:updateMask}, 'start') //AlphaMaskFilter needs to be updated on every tick if it has to tween. function updateMask(){ mask_mc.updateCache(); exportRoot.maskedContent.filters = [ new createjs.AlphaMaskFilter(mask_mc.cacheCanvas) ]; exportRoot.maskedContent.updateCache(); console.log('updating'); }
