Minecraft - Java | Find out the version of the player?

I wanted to ask how you can find out which version the player is playing with (e.g. 1.8.8).

You can find out via the protocol version (47 is e.g. 1.8 - 1.8.9).

I would have to look again how exactly that works.

If you have ViaVersion on it you can also check it with a command: / viaver list

I think that's what you're looking for:

ProtocolLibrary.getProtocolManager () getProtocolVersion (Player).

((CraftPlayer) player) .getHandle (). PlayerConnection.networkManager.getVersion ();

I would choose the first option. You have to use ProtocolLib for this
