Hi there,
Here is the first version of GAF Player for PixiJs. If you know Flump or Dragon Bones, take a look at GAF, it's so much more powerful !!! https://gafmedia.com/
At the moment, GAF Player for PixiJS is available for Haxe-Pixi but I will deliver a pure js lib soon .

Enjoy 
PS: I'm really interested in bug reports !
