The company I work for (Masque) is trying to use Spine in Haxe. I've been able to view the example assets for the owl, raptor, spineboy, dragon, and coin example animations by simply loading the .atlas file (which loads the .png files) and loading the json file, and then just playing the animations.
Note that I got these files from the spine-runtimes download (spine-runtimes\spine-haxe\example\assets) and use spine-haxe from git (https://github.com/EsotericSoftware/spine-runtimes/tree/4.1/spine-haxe).
However, several of the sample animations do not just plug and play.
spineboy is missing his feet
tank is missing the treads
vine, stretchyman, mix and match all throw an error in "PathConstraint" when attempting to load them.
Is there example code somewhere (even if in another language) that shows how to properly load and play these animations?
