clearInterval() equivalent

[Jonathan 5,176 Likes (Superhero)]

hello hello..

 

i know instead of using setInterval(), we can use delayedCall() for GSAP.. what would be the clearInterval() equivalent in GSAP.

 

In setInterval() when you declare it in a variable, returns an ID (unique identifier) which is used in clearInterval() to cancel the timer

var intervalID = window.setInterval(animate, 500);

// later called to cancel the timer
window.clearInterval(intervalID);

so my question is.. 

• what is the equivalent in GSAP to cancel a specific delayedCall() instances... since if i use killAll()

//kill only delayedCalls
TweenMax.killAll(false, false, true, false);

it kills all delayed calls, but not just a specific delayedCall()..

 

I could use killDelayedCallsTo() which kills all of the delayedCalls to a particular function..

• but is there a method to kill specific instances of delayedCalls that might have multiple delayedCall() being used, like when using clearInterval?
• does delayedCall() return a unique identifier like setInterval() does to reference later for cancelling / killing?

Below i can use the following to cancel timers at different times due to the instances referenced with the setInterval() ..

var intervalID = window.setInterval(animate, 500),
    intervalID2 = window.setInterval(animate, 1000);

// later called to cancel timer 1
window.clearInterval(intervalID);

// called again later to cancel timer 2
window.clearInterval(intervalID2);

• so what would be the equivalent to cancelling the delayedCall() on different instances like above using setInterval().. instead of cancelling all tweens associated with a function that you pass to killDelayedCallsTo() ?

let me know if i need to clarify more, and if the way im explaining my question is long winded?

HI Jonathan,

 

I think TweenLite.killTweensOf() will do the trick

 

Kills all the tweens (or specific tweening properties) of a particular object or delayedCalls to a particular function. 

 

...

 

To kill all the delayedCalls that were created like TweenLite.delayedCall(5, myFunction);, you can simply call TweenLite.killTweensOf(myFunction); because delayedCalls are simply tweens that have their target and onComplete set to the same function (as well as a delay of course).

 

TweenLite.delayedCall(2, someFunction);
//to kill
TweenLite.killTweensOf(someFunction);

If you have remaining questions, just let us know.

thanks Carl.. i will test that out..

 

do you know if delayedCall() returns anything when used in a variable instance like setInterval() does ??

Yup, delayedCall() returns a TweenLite instance.

 

delayedCall docs

 

delayedCall(delay:Number, callback:Function, params:Array = null, scope:* = null, useFrames:Boolean = false):TweenLite

 

...

 

Returns

TweenLite — TweenLite instance

 

 

 

So, since its a tween you could kill it by name:

var myDelayedCallback = TweenLite.delayedCall(2, someFunction);


myDelayedCalback.kill();

Awesome .. I missed that.. thanks again Carl..

Also, just to clarify, TweenLite.delayedCall() is an analog to setTimeout(), not setInterval().

// setTimeout()
var timeout = TweenMax.delayedCall(2, function() {
  // do something once after 2 seconds
});

// setInterval()
var interval = new TimelineMax({ repeat: -1 }).call(function() {
  // do something every 2 seconds
}, null, null, 2);
...
interval.kill();
