Well I've been messing around with particles for the last 12 hours, I got several different problems on different contexts, but right now I wanna talk about the Particle Testmod not working at all.

Well, I copy/pasted the mod in a separated repository to make things easiers, because I couldn't figure out how to run it from the module provided in this repository.

Even before the game starts with the exact same workspace of the example mod repository template (currently in this revision) the game crashes with this: https://gist.github.com/NathanPB/c00dbb93ee6adcc7720374ed8e636d4f

If I remove the "textures" entry of the JSON file at src/main/resources/assets/modid/particles/custom.json the game just loads, but just as expected the particle doesn't have a texture and its transparent (so, useless)

I'd like someone to assert me if the API is broken or I'f I'm just missing some steps or something. Thank you all

Indeed it is out of date. #593 will refactor test mods, so we can get a working particle test mod again.

This issue is now in a state where someone can whip up a particles testmod if they wish.
