Reverse timeline code for as3

Question

How would I get to play backwards a timeline from a specific frame to another frame?

I need to be able to play back from frame 62 to 1 and from 101 to 62 depending on what frame I am on. I know I can do 2 if loops with if (currentFrame == 62) etc but what is the code to play the timeline in reverse for AS3?

Answer 1

您可以使用Greensock的TweenLite类沿任一方向补间时间轴的帧。

Tweenlite.to ( mc, 1, {frame:1} );

Answer 2

Something like this:

stop();

var targetFrame:int = 62;
// if we are ahead of the target, start going backwards
if(currentFrame > targetFrame) stage.addEventListener(Event.ENTER_FRAME,goBack);

function goBack(evt:Event):void
{
    prevFrame();
    // kill the event listener when the target is reached
    if(currentFrame <= targetFrame) stage.removeEventListener(Event.ENTER_FRAME,goBack);
}
