Problems with goto label and play

[Dennis Laupman]

Hi,

 

Maybe I did smthng terribly wrong, but  I think I found an issue in GSAP 1.14.2. play('label1') doesn't work correctly. If I use the GSAP version: beta 1.8.2 it does.

 

Thank you!

Hi dennislaupman 

 

try this :

var red = $("#red");
var tl = new TimelineMax({paused:true});
		tl.to(red, 1, {left:100}, "label1")
		  .addPause()
		  .to(red, 1, {rotation:360}, "label2")
		  .addPause()
		  .to(red, 1, {scale:.5}, "label3")
		  .addPause()
		  .to(red, 1, {backgroundColor:"green"}, "label4");

$('#nextLabel').on('click', function(){
    tl.play();
})
$('#label2').on('click', function(){
    tl.play("label2",false);
})

HI, Diaco.AW,

 

You made my day! Thanks for the fast solutions. Where is the tl.play("label2",false); false used for?

Thank you very much

Hello Dennis.. Welcome to the GreenSock Forum

That second parameter is if you want events suppressed.

Checkout play() docs:

http://greensock.com/docs/#/HTML5/GSAP/TweenMax/play/
:

.play()
.play( from:*, suppressEvents:Boolean ) : *
Begins playing forward, optionally from a specific time (by default playback begins from wherever the playhead currently is).

Parameters:

from : *
(default = null) — The time (or label for TimelineLite/TimelineMax instances) from which the animation should begin playing (if none is defined, it will begin playing from wherever the playhead currently is).

suppressEvents : Boolean
(default = true) — If true (the default), no events or callbacks will be triggered when the playhead moves to the new position defined in the from parameter.

Returns : *
self (makes chaining easier)

I hope this helps

Hi Jonathan!

 

Thank you! It helps me a lot!

 

As I understand it,  the needle is set at the position in front of the "labeled" timeline action? In my case at addPause(); The second param (false) in .play() prevents this function to execute. Right?

Nice example Diaco.AW

 

Dennis, you are correct.. the addPause() method is a special callback. So if you look at

See the Pen WbbXML by MAW (@MAW) on CodePen

.. and if you remove the second param (false) in the #label2 buttons event handler. You will see how it allows the special callback to be triggered.. in this case addPause(). So by using false in the second param it allows you to jump to that label ("label2") and trigger the rotation for that tween.

 

Here is a modified pen of Diaco.AW codepen example but with an extra button.

 

One suppresses events for label 2 and the other doesnt:

 

See the Pen QwwaKW by anon (@anon) on CodePen

 

To test:

• Click Run in codepen . then click the second button called playLabel2 using false (suppressEvents)

To test again:

• Click Run in codepen . then click the third button called playLabel2 using default true  (suppressEvents)

I hope this helps!
