Opening ender chest gui causes ghost items. [1.12]

[naturaGodhead]

Hi everyone, 

 

I'm using the following code to open an enderchest via an item. However it seems like the inventories aren't synced and it causes ghost items and other glitches.

 

if(player.world.isRemote) {
			if(player.isSneaking() && Keyboard.isKeyDown(Keyboard.KEY_SPACE)){
			
			EntityPlayer playerE = (EntityPlayer)player;
			InventoryEnderChest inventoryenderchest = playerE.getInventoryEnderChest();
			
			if (inventoryenderchest != null)
				playerE.displayGUIChest(inventoryenderchest);
			}
		}

Thanks for the reply. I was under the impression gui was client side for some reason

It is, but containers (chests, things that hold an inventory) hold their items on the server, and for the game to synchronize what you're doing in the client-side-gui with the server, the server has to know that you're interacting with that container.

 

So you open the "gui" on the server.

 

What actually happens is that the server goes "cool, got the container, sending a packet to the client to open the actual gui, and maintain synchronization."
