Hi! It looks like NoteBlockAPI is not initialized or running. That is most commonly caused by shading. Make sure that you are not shading the NoteBlockAPI in your pom or build.gradle file. Also I assume that you added the NoteBlockAPI as depend or softdepend in your plugin.yml.

charlie-moomoo commented 4 months ago

I'm not shading it, and yes, I add the API to depend.

koca2000 commented 4 months ago

Would you show me your pom or build.gradle file?

Sure.

Any updates on this?

charlie-moomoo commented 2 months ago

I just found where the problem is. It's because I'm not creating the player in onEnable.
