G'day all,

Hoping someone can help me with this! I'm trying to get an mc to tween a certain way, then tween another way, using actionscript.

Here's what I've got so far:

stop();
#include "lmc_tween.as"
sun_mc.tween("_y",195,25,"easeOutSine",5);
sun_mc.brightOffsetTo(75,15,"linear",15);
moon_mc.tween("_x",225,25,"easeOutSine",5);
moon_mc.brightOffsetTo(-65,15,"linear",15);

Once the above mcs have finished tweening, I want them to do this:

sun_mc.tween("_y",325,25,"easeInSine",0);
sun_mc.brightOffsetTo(0,15,"linear",15);
moon_mc.tween("_x",100,25,"easeInSine",0);
moon_mc.brightOffsetTo(0,15,"linear",15);

...or something similar. In other words, I've got a sun and a moon - I want them to converge (creating an eclipse), and then continue moving. The reason I want to do 2 separate tweens for the movement is that I want them to slow down into the eclipse, and then speed up out of it - that can't be done in a single tween, right? Same applies for the brightness - I want the moon (for example) to get darker as it eclipses, and then brighter as it moves away.

Hope I've been clear enough - any help would be much appreciated! I'm trying to do all this stuff in Actionscript, rather than timeline motion tweens.

Cheers in advance!

You can use the onMotionFinished method with the tween class. Try the following code:

var oTweenListener:Object = new Object();
oTweenListener.onMotionFinished = function(){
	// do the next tween here.
	var tweeny:Tween = new Tween(blah blah blah);
	tweeny.addListener(oTweenListener2);
	
	var oTweenListener2:Object = new Object();
		oTweenListener.onMotionFinished = function(){
		// do the next tween here.
	}
}
var tweeny:Tween = new Tween(blah blah lbah);
tweeny.addListener(oTweenListener);

You may need to pass scope into the objects, because when the onMotionFinished is called, they lose scope. so just do:

oTweenListener._target = // my target movieclip to tween

I don't really get what you mean, sorry!

Can you use my above actionscript in yours...?

Cheers!

stop();
#include "lmc_tween.as"

// delete these import lines if you have them elsewhere.
import mx.transitions.Tween;
import mx.transitions.easing.*;
//

var sunTween:Tween = new Tween(sun_mc, "_y",195,25,"easeOutSine",5);
sun_mc.brightOffsetTo(75,15,"linear",15);
var moonTween:Tween = new Tween(moon_mc, "_x",225,25,"easeOutSine",5);
moon_mc.brightOffsetTo(-65,15,"linear",15);

var oListener:Object = new Ojbect();
oListener.sun = sun_mc;
oListener.moon = moon_mc;

oListener.onMotionFinished = function(){
var sunTween:Tween = new Tween(this.sun, "_y",325,25,"easeInSine",0);
this.sun.brightOffsetTo(0,15,"linear",15);
var moonTween:Tween = new Tween(this.moon, "_x",100,25,"easeInSine",0);
this.moon.brightOffsetTo(0,15,"linear",15);
}
sunTween.addListener(oListener);

G'day mate,

Thanks heaps for your help - I've ended up using Fuse, which is doing the trick nicely!

Good call there mate. Fuse is much, much better.

Yes, it seems very lovely so far :)
