Tweening Boolean value

[timteka]

Hi, guys, couldn't find the answer on the forum. is there any way to tween (trigger) boolean value? e.g. i have and a sprite on stage (AS3) and what to hide and show it several times. Of course i can tween the object's alpha, but it would be much more effective to tween just visibility. for example:

var tw_circle:TweenMax = new TweenMax(mc_circle, 3, {repeat:5, visible:true});

You could either make your own plugin for that or use an onUpdate like this:

 

mc.alpha = 0;
var tw_circle:TweenMax = new TweenMax(mc, 1, {repeat:5, alpha:1, onUpdate:updateVisible, ease:Linear.easeNone});
function updateVisible():void {
mc.visible = Boolean(mc1.alpha > 0.5);
mc.alpha = 1;
}

 

I'm just using alpha as a tool to determine the visible Boolean value, but I set it back to 1 each time, so visually the alpha won't actually change. You could do this with a generic object instead, but hopefully this demonstrates the concept okay.

didn't understand your answer concerning alpha, but thank u very much for the idea, 'cos TweenMax is working even without setting implicit tween params:

tw_circle = new TweenMax(circle, .3, { repeat:3, onComplete:doSmth, onUpdate:function():void{ circle.visible = !circle.visible; } } );
