[_doc.visibilityState on node.js]

Thanks -  I notice the change you made from:

_doc.visibilityState !== "hidden"

to

((_doc || {}).visibilityState  !== "hidden" 

 

I suspect that will fix it.  Nice work!

 

Since I was  only using TimelineMax I ended up changing it so that I only required the TimelineMax module

// var gsap = require('gsap');

// don't need the entire suite, so I'll just require TimelineMax on its own

var TimelineMax = require('./node_modules/gsap/TimelineMax');

 

So that way there is no TweenMax initialized which I think was an easier fix in my case.

By the way, first time poster, but long-time user of GreenSock (used to use AS version). I was delighted to discover it actually worked in node.js and was able to use it for orchestrating timelines of events on the server. Brilliant stuff! 

 

[_doc.visibilityState on node.js]

Hi, thanks, a codepen wont replicate this issue because as I said, it is running in a node.js script, but the code is:

 

var gsap = require('gsap');
TweenMax.ticker.fps(24);
TweenMax.lagSmoothing(0);

var timeline = new TimelineMax({
				//repeat: -1
				onStart: () => {
					console.log('timeline started');
				}
			});

timeline.add(() => { console.log ('test');}, 10 );
timeline.add(() => { console.log ('test');}, 20 );
timeline.add(() => { console.log ('test');}, 30 );
timeline.add(() => { console.log ('test');}, 40 );

 

It runs fine until the CPU gets under stress and then TweenMax seems to run into that issue where it is looking for a visibilityState on a _doc that doesnt exist.

 

[_doc.visibilityState on node.js]

i am using TimelineMax in node and occasionally getting this:

 

 

I am assuming this is because there is no doc with a visibilityState....

 

Anyone have any ideas how I could fix this? Ideally without having to modify the gsap source
