Get All players on a Server in a 'KeyHandler'

[Nimolo]

Hey,

 

Can anyone tell me how I can get all players on a Server ?

I try to make something like this:

When I push 'F' I should get a list with all players currently on the server and their current position.

The problem is that the server is null because the KeyHandler is called client side but how can I fix this ?

I don't want to send packets and stuff like this. I just need all players... Can I somehow run this server side ?

public class KeyHandler{

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

        @SubscribeEvent
public void KeyInputEvent(KeyInputEvent event) {
	MinecraftServer server = MinecraftServer.getServer(); //Server return null? 
                List<EntityPlayerMP> list = server.getConfigurationManager().playerEntityList;
                for (int i = 0; i < list.size(); i++) {
			EntityPlayerMP player = list.get(i);
			System.out.println(player.getDisplayName() + ": x:" + player.posX + " y:" + player.posY + " z:" + player.posZ);
		}
}
}

 

I would really appreciate any help. Thank you.

You need to send packets to get server data on the client and vice versa.

Looks like something that could be handled in a server command.

You'll be able to set a permission level, as a bonus.
