I'm working on GUI to play pong and I want to add multiplayer to it. I don't want the multiplayer menu to show up when the player is in singleplayer. I have mc.getMinecraft().isSingleplayer() called in the GUI's constructor to check if the player is playing singleplayer or not, but I'm having an issue.

 

This works perfectly fine with dedicated servers, but when playing LAN, players who join isSingleplayer() is false, but true for the host.

 

Is there any other way to fix this? (Or maybe a different way to check if on a server?)

Here is a simple condition to check if you are on a server: true.

In all seriousness: Please clarify, Minecraft is always using a server.

I meant if the player is in singleplayer or multiplayer. mc.getMinecraft().isSingleplayer() is false when I connect to a dedicated server or when I join a LAN server, but true if I host one. I thought once I turned on LAN to host, mc.getMinecraft().isSingleplayer() would become false, but it stays true, even if a player joins.

 

Basically, when I host a LAN, I need someway to tell the GUI that the player is no longer playing singleplayer

So you want to check if more than one player is playing?

On the client:

NetHandlerPlayClient::getPlayerInfoMap().size() > 1

 

On the server:

PlayerList::getPlayers().size() > 1

That works. Thanks
