MinecraftServer.getServer() returns null! [Help]

[Nimolo]

Hey,

 

I noticed when I use MinecraftServer.getServer() on a singleplayer i get the real instance but when I use this method on a multiplayer server it returns me null. Why is that so ?

 

Here my simple code:

public class KeyHandler{

private KeyBinding key = new KeyBinding("Key", Keyboard.KEY_F, "KEY");

        @SubscribeEvent
public void KeyInputEvent(KeyInputEvent event) {
	if(key.getIsKeyPressed())System.out.println(MinecraftServer.getServer() == null); // returns null on multiplayer server, returns the actual instance in singleplayer
}
}

 

I register it in my main class:

FMLCommonHandler.instance().bus().register(new KeyHandler());

 

Why is this always returning null when I try to use it on an actual multiplayer server? That's so frustrating...

 

Can anyone please help me ?

 

Thank you very much.

Keys are handled client side, thus getting the server will be null.

So how can i get the server instance then ?

You need to send packets.

Packets are the easiest things I've used.

Why do you want the server instance on a client anyways ?

The packet stuff is old now (1.6.4) but the concepts are the same.
