I'm trying to get data from tileentity for the gui, but I can't figure out how to get the tileentity (or the position) from the gui.
I'm using network to get data, but I really don't know how to receive those.

GuiCode: https://github.com/Insane-96/XpHolder/blob/master/common/net/insane96mcp/xpholder/gui/TestGui.java#L108
Packet Used: https://github.com/Insane-96/XpHolder/blob/master/common/net/insane96mcp/xpholder/network/DepositMessage.java

And handler: https://github.com/Insane-96/XpHolder/blob/master/common/net/insane96mcp/xpholder/network/DepositMessageHandler.java

 

I'm stuck because I don't know how to get the pos from the gui.

But how can I set a field in the TestGui from the packet handler? https://github.com/Insane-96/XpHolder/blob/master/common/net/insane96mcp/xpholder/network/GetXpHeldMessageHandler.java#L29

Just had to send a response packet, get the gui and set the value
 

Spoiler

@Override
	public IMessage onMessage(GetXpHeldResponse message, MessageContext ctx) {
		EntityPlayerSP player = Minecraft.getMinecraft().player;
		int xpHeld = message.xpHeld;
		GuiScreen guiScreen = Minecraft.getMinecraft().currentScreen;
		if (guiScreen instanceof TestGui) {
			TestGui testGui = (TestGui) guiScreen;
			System.out.println("xp held: " + xpHeld);
			testGui.xpHeld = xpHeld;
		}

		
		return null;
	}

 

But now I'm having another problem.
I get a classCastException when trying to open the gui at https://github.com/Insane-96/XpHolder/blob/master/common/net/insane96mcp/xpholder/block/BlockXpHolder.java#L43

I don't need a container that's why I've extended a TileEntity and not a Container

Also, your message handlers are broken, read the warnings in the documentation.

Should I send a reply to a packet manually since I can't return a packet from the Runnable?

Tileentity data to the client

Try to use this to sync your tileentity to the client side:

IBlockState state = getWorld().getBlockState(getPos());
getWorld().notifyBlockUpdate(getPos(), state, state, 3);

But you are already sending a packet to open the GUI. Send whatever data you need with that packet.

Yeah but I need to update data during the use of the tile entity

I have a strange problem. In LAN when a non-host opens the GUI, the GUI opens for the host too.

EDIT: doesn't happen on SMP
