TweenLite tint flickering

[shanethehat]

Hi,

 

I'm trying to change the tint on a sprite in a loop. This works fine, but when I place another sprite at a higher depth that contains a gradient, the tint animation flickers. Any idea why, or how to prevent it?

 

package  {
import com.greensock.plugins.TintPlugin;
import com.greensock.plugins.TweenPlugin;
import com.greensock.TweenLite;
import flash.geom.Matrix;
import flash.display.GradientType;
import flash.events.Event;
import flash.display.Sprite;
public class Background extends Sprite
{
	private var colorClip			:Sprite;
	private var gradClip			:Sprite;

	private var nextColor			:int = 1;

	private var colors			:Array = new Array(0xff0000,
										     0x00ff00,
										     0x0000ff
										     );

	public function Background():void
	{
		TweenPlugin.activate([TintPlugin]);
		if(stage) {
			init();
		} else {
			addEventListener(Event.ADDED_TO_STAGE,init);
		}
	}

	private function init(evt:Event = null):void
	{
		colorClip = addChild(new Sprite()) as Sprite;
		colorClip.graphics.beginFill(colors[0]);
		colorClip.graphics.drawRect(0,0,654,274);

		var mat:Matrix = new Matrix();
		mat.createGradientBox(654,274,toRad(-90));
		gradClip = addChild(new Sprite()) as Sprite;
		gradClip.graphics.beginGradientFill(GradientType.LINEAR, [0x000000,0x000000], [.7,0], [0,255],mat);
		gradClip.graphics.drawRect(0,0,654,274);
		gradClip.cacheAsBitmap = true;

		startColorTimer();
	}

	private function startColorTimer():void
	{
		TweenLite.delayedCall(4,changeColor);
	}

	public function changeColor():void
	{
		TweenLite.killTweensOf(changeColor);
		TweenLite.to(colorClip,1,{tint:colors[nextColor],onComplete:startColorTimer});
		(nextColor+1 < colors.length)?nextColor++:nextColor=0;
	}

               private function toRad(a:Number):Number 
	{
		return a*Math.PI/180;
	}
}
}

hmm, not really. my gut says this is more of a Flash Player issue than a GreenSock issue.

 

if you attach and fla or swf, perhaps one of us can verify whether or not it happens for everyone.

 

very strange.

Thanks for the reply. It does seem to happen on all the machines I've tested on, I guess I'll just have to do it differently.
