Hello,

I've created a fade in with the timeline, calling it in a function with object.play();
How can I, with another function, reverse the timeline?

So that I get a fade-out instead of fade-in?

So instead of playing frame 1-30, it goes 30-1

Create a recursive function like this:
function reverse():void
{
   if( object.currentFrame > 1 ){
        object.gotoAndStop( object.currentFrame - 1 );
        reverse();
   }
}

I've done the following
function btnOutFunction(e:MouseEvent) {
	   if( txtObjectMC.currentFrame > 1 ){
        trace(txtObjectMC.gotoAndStop( txtObjectMC.currentFrame - 1 ));
        btnOutFunction(e);
   }
}

Open in new window


But it gives as output "undefines, undefined, undefined, etc."
maybe it needs a delay? but how?

try this:
function btnOutFunction(e:MouseEvent) {
          reverse();
}

function reverse() {
           if( txtObjectMC.currentFrame > 1 ){
        trace(txtObjectMC.gotoAndStop( txtObjectMC.currentFrame - 1 ));
        reverse();
   }
}

Try this..

function btnOutFunction(e:MouseEvent) {
   txtObjectMC.addEventListener(Event.ENTER_FRAME, onObjEnterFr);
}
function onObjEnterFr(e:Event):void{
	if( txtObjectMC.currentFrame > 1 ){
		 txtObjectMC.gotoAndStop( txtObjectMC.currentFrame - 1 );
	}else{
		txtObjectMC.removeEventListener(Event.ENTER_FRAME, onObjEnterFr);
	}
}

sorry the code is:
function reverse() {
           if( txtObjectMC.currentFrame > 1 ){
        txtObjectMC.gotoAndStop( txtObjectMC.currentFrame - 1 );
        reverse();
   }
}

or try this:
function reverse() {
           if( txtObjectMC.currentFrame > 1 ){
        txtObjectMC.prevFrame();
        reverse();
   }
}

Hi deepanjandas, The time taken for every iteration while recursive call will not update the stage. So it will look like a jump to first frame. I think better way to use Enter_Frame event. Please correct me if i'm wrong.

Hmm..may smabudhahir is right.. ErnstJacobs you may use the ENTER_FRAME event to run the reverse functiion and clear it on the condition achieved.
