Hello dear modders,

I started to do stuff with tilentities and guis. My problem is, that i can't access the data on my tileentities from the gui, because it is not the same tile entity as the block i clicked on to open the gui.

I have coordinates stored in an nbt integer array in a controller block and i want to display how many coordiantes i have stored on the gui. I created a `int ID` which is set in the constructor to check if it gets instantiated more than I would want, and I was right about that.

Any idea why that is happening?

 

In my screen class:

@Override
protected void drawGuiContainerForegroundLayer(MatrixStack matrixStack, int mouseX, int mouseY) {
	GateControllerContainer container = getContainer();
	GateControllerTileEntity tileEntity = container.tileEntity;
	int placerCount = tileEntity.getPlacerCount();
	
	font.drawString(matrixStack, title.getString(), 8.0f, 6.0f, 4210752);
	font.drawString(matrixStack, "Bound to " + placerCount + " placers", 8.0f, 50.0f, 4210752);
	font.drawString(matrixStack, playerInventory.getDisplayName().getString(), 8.0f, 70.0f, 4210752);
}

I set the tileEntitiy variable in my container class in its constructor

And in my TileEntities class:

@Override
protected Container createMenu(int id, PlayerInventory player) {
	return new GateControllerContainer(id, player, this);
}

 

Thanks in advance for your tips

On loadup i can see that 4 of my tileentities have loaded their data:

the first number is the ID of the tileEntity.

when i access the guis of these i always have a higher ID than that and the tileEntities don't have data on them

This is what i am doing to open the gui:

 

@Override
public ActionResultType onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player,
		Hand handIn, BlockRayTraceResult hit) {
	if(!worldIn.isRemote) {
		TileEntity tileEntity = worldIn.getTileEntity(pos);
		ItemStack heldItemStack = player.getHeldItemMainhand();
		if(heldItemStack.getItem() instanceof BlockItem) {
			BlockItem heldBlockItem = (BlockItem)heldItemStack.getItem();
			if(heldBlockItem.getBlock() instanceof GatePlacer) {
				GatePlacer heldPlacer = (GatePlacer)((BlockItem)heldItemStack.getItem()).getBlock();
				heldPlacer.setController(this);
				player.sendStatusMessage(new StringTextComponent("Set new controller"), false);
			}
		} else if(tileEntity instanceof GateControllerTileEntity) {
			NetworkHooks.openGui((ServerPlayerEntity)player, (GateControllerTileEntity)tileEntity, pos);
			return ActionResultType.SUCCESS;
		}
	}
	return ActionResultType.FAIL;
}

is that correct?

Ok, i'll try it. Thanks for the lightning fast help 🙂

Ok so I found the method @diesieben07 meant and it works now, thanks for the help, again.

Just for anyone stumbling over this:

In the onBlockActivated method of the block that has the gui, do something like this:

NetworkHooks.openGui((ServerPlayerEntity)player, controllerTileEntity, 
	(buffer) -> { 
		buffer.writeBlockPos(pos); 
		// write to it whatever you want
	} 
);

And then on the Container for that TileEntity:

public GateControllerContainer(final int windowID, final PlayerInventory playerInventory, final PacketBuffer data) {
	// in the data variable lies the information you sent when calling openGui
}

As far as I know you have to have this constructor anyways, because you cannot register the container otherwise (but I am not sure about this)
