Working on it. Also working it a GDExtension, which is so much worse than just a minor version bump. Not sure I'll live to see it completed.
Support for Godot 4.3
Welp, that was easy enough. Currently building 4.3 binaries, you can download them once this workflow is complete:
EsotericSoftware/spine-runtimesactions/runs/10452919280
Yeah, had to rejigger some things. Building again!
EsotericSoftware/spine-runtimesactions/runs/10467909475
Yes, but it will take a while for that to materialize.
Looking forward to the GDExtension! Hopefully that'll fix the missing icons for spine assets.
It is indeed not as straight forward. It's actually a massive pain going from an engine module to an extension, as the API exposed is what you get in GDScript, not what you get in C++ when writting an engine module. It's similar enough, but requires tons of specializing if you want to keep both a module and extension build. We'll keep providing both.
The web and C# story is still pretty much up in the air. However, W4 Games seem to be working on (or at least looking into?) that. We've been exchanging emails about spine-godot as an extension for a few months now, so I keep reporting the pain points. Whether that means Godot itself, which isn't owned or managed by W4 Games, will fix this up, I don't know.
I actually kept asking for a guide or build system template to cover all bases. But nothing like that exists at the moment.
