Hello!
I’m not sure if this is the right place to request this but here goes:
I was wondering if it would be possible to add a feature into sponge to allow music streaming for radios like Hive365 and for servers to have there own radios, maybe have songs play in areas without having to download a custom resource pack (bit like Wynncraft)
Sponge is an api, or coremod, it will run in the background and does not have any user-visible features. all the features will be background for plugin devs.
There’s no way that you could get music to play in-game without a client mod, other than songs made entirely of noteblock sounds or possibly other sounds in minecraft, or just C418 disc songs. You could simply require users to download a resource pack with custom music, however, that would mean you would be fairly limited with the kind of music you could play to players, it would not really be an authentic “Radio” type of experience because you’re limited to just a few songs with resource packs.
One thing I recommend… Just set up a plug.dj for your server. It’s a cool little website
