[1.12.2] How can I close GUI in Forge?


Filip4223

Recommended Posts

I am trying to write an Minecraft Forge (1.12.2) mod. It should work like that:

OnGuiOpen: If GUI title is equals to constant string value then close GUI (like ESC). That must be known by the server exactly like closing a GUI by clicking E/ESC.

 

My code (doesn't work - I'm seeing 'Turning off' in console but gui is still turned on)
 

public class ModEventHandler {
	@SubscribeEvent
	public void onGuiOpen(GuiOpenEvent event)
	{
		if(event.getGui() instanceof GuiContainer) {
			checkGui((GuiContainer) event.getGui());
		}
	}

	private void checkGui(GuiContainer gui) {
		if(gui.inventorySlots instanceof ContainerChest) {
			ContainerChest _gui = (ContainerChest)gui.inventorySlots;
			
			String text = _gui.getLowerChestInventory().getDisplayName().getUnformattedText().toString();
		
			if(text.contains(" ")) {
				System.out.println("Turning off");
				Minecraft.getMinecraft().player.closeScreen();
				Minecraft.getMinecraft().displayGuiScreen(null);

				KeyBinding.onTick(Keyboard.KEY_ESCAPE);
			}
		}
	}
}

 

Thank u in advance for help ;)

To prevent the GUI from opening in GuiOpenEvent you need to cancel the event.

I did it, but I think it's only clientside prevention. I gotta send real packet "close gui" to trigger serverside InventoryCloseEvent (or something like that).

Then you must first let the GUI open (GuiOpenEvent fires before its open!) and then call:

OK, it works.Tthanks. :) 

 

I wonder is there better way for doing it instead of creating new thread? 

 

System.out.println("Turning off");

Thread thread = new Thread(new CloseGui());
thread.start();


//CloseGui class

public void run() {
  try {
    Thread.sleep(500);
  } catch (InterruptedException e) {
    e.printStackTrace();
  }

  System.out.println("closing");
  Minecraft.getMinecraft().player.closeScreen();
}
