MovieClip that doesn't loop

[eigenface]

I often want to play through a MovieClip once and then not loop again. Flash appears to have built-in behavior for this, because you can use the right-click menu on a running swf to uncheck "loop", and then the MovieClip will stop once it gets to its last frame. However, I cannot find any way to access this behavior using actionscript. The best I can do is listen for enterFrame events and check if currentFrame == totalFrames on each and every frame, then stop the clip and remove the listener on the final frame. Am I missing something? Is there a better way?

 

The reason I bring this up here is I've been using TweenMax as an alternative, like so:

 

clip.gotoAndStop(1);

TweenMax.to(clip, clip.totalFrames, { frame:clip.totalFrames, useFrames:true });

 

Will this produce exactly the same result as listening for enterFrame events and stopping the clip when currentFrame == totalFrames? Or is there some timing/delta-frames weirdness with FramePlugin and useFrames?

I guess potentially, since I'm tweening from frame 1 to totalFrames instead of from frame 0 (which doesn't exist) to totalFrames, I should do:

 

clip.gotoAndStop(1);

TweenMax.to(clip, clip.totalFrames - 1, { frame:clip.totalFrames, useFrames:true });

 

This that right?

Sure you can use TweenMax that way, but it's not necessary. All you need to do is go to the last frame of your MovieClip in the Flash IDE, add a blank keyframe, and add one simple line of ActionScript there: stop();

 

By the way, make sure you use the Linear.easeNone ease if you're going to use TweenMax. Otherwise, it'll apply a Quad.easeOut (the default) ease across the whole tween. That can be a very cool effect in certain cases, but if you want it to play linearly, use Linear.easeNone.

Thanks, I'd done that in the past, but recently I've been trying not to put any code in on the timeline. I guess one line wouldn't hurt.

So should duration be totalFrames or totalFrames - 1?

totalFrames - 1
