Correct way to add, remove and re-add child- to parent-timeline?

[powtoon]

Hi,

 

i am sequencing timelines on a master timeline which tween graphic objects (UIComponents) in a flex application.

 

sometimes i want to move a child timeline on the master timeline, so instead of say at second 5 it will start at second 8.

 

so i do something like this:

 

private var master:TimelineMax = new TimelineMax();

private var child1:TimelineMax = new TimelineMax();
//add tweens to child1

private var child2:TimelineMax = new TimelineMax();
// add tweens to child2, fading in and out objects.

master.insert(child1, 0);
master.insert(child2, 5);

//some function calls:
master.play();

//and another this:
master.stop();
master.remove(child2);
master.insert(child2, 8);

// and again another function calls:
master.gotoAndPlay(0);

 

after i remove and re-add the timeline, the objects tweened by the second timeline are not visible any more. i can see in the debugger that they still exist but they seem to being set to visible false or something like that...

 

any ideas highly appreciated.

 

thanks,

This is not something I often do, but I made an example and had no problems.

Instead of removing and re-inserting your child2, you can alternately just change child2's startTime.

 

my sample looks like this:

 

import com.greensock.*;

var mainTl:TimelineMax = new TimelineMax({onUpdate:showTime});
mainTl.insert(TweenLite.to(black, 5, {x:520}));

var blueTl:TimelineLite = new TimelineLite();
blueTl.insert(TweenLite.to(blue, 1, {y:0}));

mainTl.insert(blueTl, 4);

TweenLite.delayedCall(2, shiftBlue);

function shiftBlue(){
 trace("remove");
 mainTl.remove(blueTl);
 mainTl.insert(blueTl, 3);
//or instead of removing and re-inserting you can change the startTime
//blueTl.startTime = 3;
}

function showTime(){
    time_txt.text = mainTl.currentTime.toFixed(2);
}

 

cs4 attached.

 

if you continue to experience weird results, please provide a very simple file that illustrates the error. thanks
