[1.7.10]Gui openable only for one player


Recommended Posts

My GuiLobby class:


public class GuiLobby extends GuiScreen{
    public boolean doesGuiPauseGame()
        return false;
int guiWidth = 256;
int guiHeight = 168;

public void drawScreen(int x, int y, float ticks){
int guiX = (width - guiWidth) /2 ;
int guiY = (height - guiHeight) /2 ;
GL11.glColor4f(1, 1, 1, 1);
mc.renderEngine.bindTexture(new ResourceLocation(Main.MODID + ":" + "textures/gui/Lobby.png"));
drawTexturedModalRect(guiX, guiY, 0, 0, guiWidth, guiHeight);
fontRendererObj.drawString("CRIME.NET", guiX + 40, guiY + 5, 0x404040);
super.drawScreen(x, y, ticks);


This is what the gui looks like for now by the way...

width=800 height=418http://s30.postimg.org/v3tnvkze9/2015_09_06_18_19_03.png[/img]


So how can I make it that when another player is already in the gui, nobody else can open it(on a LAN/server of course)?

Look at how a chest works.  It knows how many people are in it so it can animate open and closed.  You should do something similar, only then disallow the interaction when the player attempts to open the GUI if there's already someone in it.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.
