Yes, there are apparently multiple Tween classes in Flash 8 (and maybe
MX 2004 -- I didn't check that). The one I've most often seen used is
mx.transitions.Tween, not the one in mx.effects that you imported. Here
is an example of your code (except I used 21 fps instead of 61 so I
wouldn't have to paste 60 lines of output) used with that class.
onMotionFinished does report when it's done, and there's also a
onMotionChanged that apparently reports once per frame. Here is the
frame-based code and output:
import mx.transitions.Tween;
import mx.transitions.easing.*;
function myTweenFunc(){
var tw:Tween = new Tween(myMC,"_x", Regular.easeInOut, -310, 20, 10,
false);
tw.FPS = 21;
tw.onMotionFinished=function(){
trace('finished moving lance');
}
// the time property appears to actually be frame count for
frame-based tweens
tw.onMotionChanged = function() {
trace('changed, time='+this.time+' prevPos='+this.prevPos);
}
}
myTweenFunc();
changed, time=1 prevPos=-310
changed, time=2 prevPos=-303.4
changed, time=3 prevPos=-283.6
changed, time=4 prevPos=-250.6
changed, time=5 prevPos=-204.4
changed, time=6 prevPos=-145
changed, time=7 prevPos=-85.6
changed, time=8 prevPos=-39.4
changed, time=9 prevPos=-6.39999999999998
changed, time=10 prevPos=13.4
finished moving lance
and this is the change to the tween line and output for a time-based
tween (tween dur=1 second, 20 fps movie)
var tw:Tween = new Tween(myMC,"_x", Regular.easeInOut, -310, 20, 1,
true);
changed, time=0.055 prevPos=-310
changed, time=0.109 prevPos=-306.9145
changed, time=0.158 prevPos=-297.88138
changed, time=0.206 prevPos=-284.53672
changed, time=0.259 prevPos=-266.71528
changed, time=0.311 prevPos=-241.57738
changed, time=0.362 prevPos=-211.34458
changed, time=0.414 prevPos=-176.33512
changed, time=0.465 prevPos=-135.17608
changed, time=0.517 prevPos=-89.4505
changed, time=0.567 prevPos=-37.95478
changed, time=0.619 prevPos=8.76121999999998
changed, time=0.671 prevPos=51.93578
changed, time=0.722 prevPos=89.59418
changed, time=0.773 prevPos=121.17032
changed, time=0.824 prevPos=147.44042
changed, time=0.876 prevPos=168.40448
changed, time=0.928 prevPos=184.31648
changed, time=0.989 prevPos=194.71232
changed, time=1 prevPos=199.87658
finished moving lance

Hi
having some difficulty getting the handlers working with the built-in Tween
class
also, does the Tween class actually exist in more than one place?
//CODE START
import mx.effects.*;
import mx.transitions.easing.*;
function myTweenFunc(){
myMC.onTweenUpdate = function(value) {
this._x = value;
}
var tw = new Tween(myMC,-310, 20, 500,false);
tw.easingEquation = Regular.easeInOut;
tw.FPS=61;
//the following handler doesn't work!!!!
tw.onMotionFinished=function(){
trace('finished moving lance');
}
}
myTweenFunc();
//CODE END
Any suggestions?
Thanks in advance
