Mouse Event TweenEvent animations help
I have a scrollbar that animates in yoyo to 100% alpha and back to 0%. On the Roll Over I add a glow effect but I'm having trouble getting the yoyo alpha effect to stay at 100% once the roll-over happens. Currently it adds the glow but still animates the alpha back-and-forth. New to AS3 and not sure how to do it. Little help would be much appreciated!
