I'm curious how I can create a delay that is not affected by the timeScale property. For instance, I'd like a variable that changes the overall speed of each animation, but not the amount of time that it pauses for. In my example, the timeSpeed constant could go from .5 to 3.


Is there an easy way to tell timeScale to ignore delays?

const timeSpeed = .5;
const pauseTime = 1;

const tl = new TimelineMax({repeat: -1});
tl.timeScale( timeSpeed );

tl.to("div", .5, {x: "+=100", y: "+=100"})
  .to("div", .5, {x: "-=200", delay: pauseTime})
  .to("div", .5, {x: "+=100", y: "-=100", delay: pauseTime})
  .to("div", 0, {delay: pauseTime})

Adding delay to tweens using delay method does not get affected by the TimeScale but it seems like it does get affected by globalTimeScale or timeScale of parent timeline. So you will need to set timescale on individual tweens instead of timeline.

if you want to change globalTimeScale or parent timeline's timeScale and want the tweens to keep delay then you will need to update delay and multiply it with timeScale.

Yep, exactly. If you change the timeScale of a timeline, it would of course affect all of its children (including delays) because the parent playhead is literally moving at a different pace. It would be really weird if the delays weren't affected because that would totally change their placement in the timeline (their startTime()) in relation to each other. 


That would be sorta like if you moved a <div> to new coordinates, but you only wanted its children to move without factoring in their padding or margin values. See what I mean? 


But yeah, you can totally get the effect you want, you'd just need to adjust each of the delays or startTimes accordingly, as @Sahil mentioned. 


Here's a function that might be helpful:

function timeScaleSkipDelays(tl, timeScale) {
    var children = tl.getChildren(),
        ratio = timeScale / tl.timeScale(),
    for (i = 0; i < children.length; i++) {
        children[i].delay( children[i].delay() * ratio );


Then you can just use that function to change the timeScale and it'll automatically alter the delays to compensate. Is that what you're looking for?
