@Cassie , no problem. Let me explain
The gsap v3 docs for Easel https://greensock.com/docs/v3/Plugins/EaselPlugin
has the following segment:
//setup a "tick" event listener so that the EaselJS stage gets updated on every frame/tick
gsap.ticker.addEventListener("tick", stage.update, stage);
stage.update();
If we try to run it, it doesn't work.
Why? The solution is on this other gsap v3 doc page. https://greensock.com/docs/v3/GSAP/gsap.ticker
Which I only found the connection via this post. After googling for a while.
I only asked for a code snippet update to properly reflect v3's notation.
Also, I'm asking on this thread since I didn't find a better place to request documentation updates.
The opacity solution can be ignored. I figure the tintAmount prop on the code snippet does the same.
