Hi! I’m not planning to publish the editor’s source code for now, but there are already several community integrations for other engines, so the format is fairly simple to figure out and work with.
I definitely plan to add more documentation about how the SpriteLoop format works (spla), which should make integrations even easier.
For now, you can take a look at how the Defold extension works: https://github.com/Balkan-Ram-Games/spriteloop-defold
You can also check out some of the integrations already created by the community: https://balkanramgames.itch.io/spriteloop/devlog/1642187/community-integrations-tools
Thanks for considering adding SpriteLoop support to your engine! I’d love to check it out too.
