Here’s a simple wrapper around the ‘C’ API for spine, courtesy of c2mx2 (completely untested but it builds!):

Note: You’ll need to get the contents of the spine-c dir from github:
https://github.com/EsotericSoftware/spine-runtimes
The spine runtimes are ‘evaluation only’, so I don’t think it’s suitable to include this with monkey2 as I want anyone to be able to use monkey2 without having to worry about any licensing headaches.
I’m sure there is some way this can be made available (probably including the spine-c code) possibly via a ‘licensed modules’ page or something. I’ve contacted the spine guys about this.
