    I´m creating a flame using Flint, and it´s goint fine. But I must make the emitter to move on the stage, and make the flame to move as realistic as possible. I imagine that following the tutorials and source files I can´t do that.

    The effect I look is the same as http://d2fhka9tf2vaj2.cloudfront.net/tuts/001_flintParticles/Tutorial/SWFs/BurningFuse.html but using TweenMax to move the MC.

    Any help on this will be great! thanks

    Two options come to mind...

    1. Create a custom activity to position the emitter using TweenMax...

    package
    {
    import org.flintparticles.common.activities.ActivityBase;
    import org.flintparticles.common.emitters.Emitter;
    import org.flintparticles.twoD.emitters.Emitter2D;

    public class CustomActivity extends ActivityBase
    {
    override public function update( emitter : Emitter, time : Number ) : void
    {
    var e:Emitter2D = Emitter2D( emitter );
    // Use TweenMax and time to set e.x and e.y
    // N.B. time is the time since the previous update
    }
    }
    }

    2. Use the FollowDisplayObject activity to make the emitter follow a DisplayObject. Then use TweenMax to update the position of the display object.
