Runtime License / CLA

joa

Hey,

I am interested in building a Spine runtime based on one of the existing Java/AS3 implementations.

Since it would be a derivative work, I'd like to know who I can contact regarding this stuff or of if you guys have some sort of CLA I could sign.

Cheers,
Joa

Hi Joa, you can go ahead and create a new runtime that makes use of the official Spine Runtimes, you just need to include the Spine Runtimes license.

Fantastic, Thanks! I'll keep you posted on the progress

Runtime works like a charm. You can see a sample here: https://www.defrac.com/sample-spine/
Code is available here: https://github.com/defrac/defrac-gaming/

I noticed during debugging that you're calculating unnecessary vertex information. For example in the raptor, a SkinnedMeshAttachment uses only triangle indices in the range [0, 30], yet there are 80 vertices for which the whole weight-calculation is performed.

I'm not sure if this is old news to you and maybe this has already been fixed? The simple solution would be to emit only used vertices in the exporter.

Looks cool! Java that runs in a browser? What magic is this?

I noticed you have ported the spine-libgdx runtimes, but your project has an Apache license. You'll need to include the Spine Runtimes license with your project.

Which attachment on the raptor has vertices that aren't used in the triangles?

It's called defrac. We compile any Java bytecode to JavaScript, native iOS, Android and JVM of course. We also include a standard library for multi-platform development. Hence the addition of some gaming utilities.

Done

My mistake, it's all good. Just checked again and I must have had a broken state.

defrac looks neat! FWIW, I'm co-author of libgdx, which is also a Java framework. We use GWT to compile for browsers, Java for desktop and Android, and RoboVM for iOS.
