[Papervision3D] Stoping a DAE Loop

[Andre Assalino]

Easy fix actually! I hadn't looked at the DAE class in detail.

So basically I added the following to the class:


        private var _loop:Boolean = false;


My Dae constructor now has a 3rd parameter, for loops:

        public function DAE(autoPlay:Boolean=true, name:String=null, loop:Boolean = false)
        {
            super(name);
            _autoPlay = autoPlay;
            _rightHanded = Papervision3D.useRIGHTHANDED;
            _loop = loop;
        }


And then the "project" function gets an if statement, where before it was:

                var time:Number = elapsed / duration;

                for each(var channel:AbstractChannel3D in _channels)
                {
                    channel.updateToTime(time);
                }

It changes to:

                var time:Number = elapsed / duration;

                if (time == 0 && !_loop)
                {
                    stop();
                }
                else
                {
                    for each(var channel:AbstractChannel3D in _channels)
                    {
                        channel.updateToTime(time);
                    }
                }

It works like a charm.

Hope it helps someone else too :)

Cheers

sorry, rewind needs to be updateToFrame, not updateToTime ;)

I've been doing this when the ANIMATION_COMPLETE fires (which I was believing was when the animation frames had all been parsed, not when the animation had completed playing):

private function handleAnimationComplete(e:FileLoadEvent):void
        {
            _channels = animatedAirplane.getAnimationChannels();

            trace("channel count", _channels.length);
            rewind();

            _numFrames = 0;
            _currentFrame = 1;

            for each(var channel:AbstractChannel3D in _channels)
            {
                _numFrames = Math.max(_numFrames, channel.keyFrames.length);
                channel.updateToFrame(_currentFrame);
            }

            //trace("read the channels");
            dispatchEvent(e);
        }

I also have these helper functions:

public function rewind():void
        {
            trace("channels length", animatedAirplane.getAnimationChannels().length);
            for each(var channel:AbstractChannel3D in _channels)
            {
                channel.updateToTime(1);
            }
        }

        public function gotoFrame(frame:Number):void
        {
            for each(var channel:AbstractChannel3D in _channels)
                channel.updateToFrame(frame);
        }


but to be honest, it's not working very well, I can't see to get the animation to stop on the first frame successfully.  On top of that, the false flag for autoplay doesn't seem to work either.  I've talked to Tim about it just this last week, and there's only one line in DAE that deals with that flag.  So I'm not sure what the issue is.

Thanks for the tips.

Cristoph, your's wouldn't work because I want it to NOT loop and what you're saying just affects the autoPlay.

And Avery, using a timer could be bad, because if there's cpu lag, it might affect the animation and stop before it reaches the end. Right?

So there should be an animation listener and I could just go ON_FINISH, dae.stop();

I'm guessing that doesn't exist then?

Cheers,
Andre

You could set up a timer with a stop action

var t = new Timer(3000, 1);

you can use the autoplay flag

var dae:DAE = new DAE(false);

then then the first frame of your animation will be displayed unless
 you
switch to play
