[1.14.4] [SOLVED] Gui Slots Behave Weird

[StefanDeSterke]

Hi, I have this weird bug where I can't move items properly around in my custom Gui. I'm trying to create a Gui with a container without the block being used being a TileEntity. Something like a crafting table. However, as I just said, I can't move the inventory items properly around. Here's a video of me trying to do something in the  gui:

 

 

Container Class:

package mod.sds.terrariamod.containers;

import org.apache.logging.log4j.LogManager;

	private final FurnaceInventory inventory;
	private final World world;
	private final BlockPos blockPos;

	public ContainerFurnace(int id, PlayerInventory playerInv, World worldIn, BlockPos pos) 
	{
		super(ContainerList.furnace, id);
		
		this.inventory = new FurnaceInventory(this);
		this.world = worldIn;
		this.blockPos = pos;

Changed Container Class:

	private final IItemHandler inventory;
	private final World world;
	private final BlockPos blockPos;

	public ContainerFurnace(int id, PlayerInventory playerInv, World worldIn, BlockPos pos) 
	{
		super(ContainerList.furnace, id);
		
		this.inventory = new ItemStackHandler(3);
		this.world = worldIn;
		this.blockPos = pos;
		
		this.addSlot(new SlotItemHandler(this.inventory, 0, 39, 35));
		this.addSlot(new SlotItemHandler(this.inventory, 1, 57, 35));
		this.addSlot(new SlotItemHandler(this.inventory, 2, 124, 35));
		
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 9; j++) {
                this.addSlot(new Slot(playerInv, j + i * 9 + 9, 8 + j * 18, 84 + i * 18));
            }
        }
        for (int i = 0; i < 9; i++) {
            this.addSlot(new Slot(playerInv, i, 8 + i * 18, 142));
        }
	}

 

I open the GUI in my custom Stone Furnace Class in the onBlockActivated method:

	@SuppressWarnings("deprecation")
	@Override
	public boolean onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) 
	{	

		Minecraft.getInstance().displayGuiScreen(new StoneFurnaceGUI(new ContainerFurnace(guiId, player.inventory, worldIn, pos), player.inventory, new StringTextComponent("Stone Furnace")));
		
		return super.onBlockActivated(state, worldIn, pos, player, handIn, hit);
	}

This is not how you open GUIs.

[StefanDeSterke]

I kind of know, but then I need to use NetworkHooks.openGui(), and I need an INamedContainerProvider, and I don't know how to use that and where to implement that.

Yes, that is valid. But my point was that's not how (generic) you do the thing (generic) you are trying to do right now.

Which I found by searching this (which is in a banner at the top of every page here on the forums) for "container"

[StefanDeSterke]

Ok, but since I don't have a tileentity class, where would I implement INamedContainerProvider? (I don't have one because I don't need to store inv data to the block)

Er, what are those slots in your GUI in your very first post for, if not for displaying your block's inventory?  You need a tile entity and there is absolutely no way around that.

I want to create an empty container when you open the block (Like a crafting table). When you close out of the inventory, then all the items that are in the slots of the furnace will pop back into your inventory,

Ah, ok.  What diesieben said, then

[StefanDeSterke]

Ok thank you, but now I'm getting this error when I'm opening the Furnace:

 

java.lang.UnsupportedOperationException: Unable to construct this menu by type

 

I think it has to do with the container type registration not being correct, so here's the code for that:

		@SubscribeEvent
		public static void onContainerRegistry(final RegistryEvent.Register<ContainerType<?>> event) 
        	{
			event.getRegistry().registerAll(
					
					IForgeContainerType.create((windowId, inv, data) -> {
						
						BlockPos pos = data.readBlockPos();
						return new ContainerFurnace(windowId, inv, TerrariaMod.proxy.getClientWorld(), pos);
						
					}).setRegistryName("container_furnace")
					
					
					);
		}

 

[StefanDeSterke]

What do I have to put as second argument in ScreenManager.registerFactory? It's asking me to put an IScreenFactory in there.

[Draco18s]

As an example:

https://github.com/Draco18s/ReasonableRealism/blob/1.14.4/src/main/java/com/draco18s/harderores/client/ClientEventHandler.java#L19

A "factory" is just a method that returns a given type, in this case your GuiScreen. Most of the time you will be able to do this through a 0-parameter constructor.

[StefanDeSterke]

Nope, still getting the same error.

 

Registry class:

	@Mod.EventBusSubscriber(modid = TerrariaMod.modid, bus = EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
	public static class ClientRegistryEvents {
		
		@SubscribeEvent
		public static void FMLClientSetupEvent(FMLClientSetupEvent event){
			
			ScreenManager.registerFactory(ContainerList.furnace, StoneFurnaceGUI::new);
			
		}
		
		
	}

Did you do this? Show the corresponding code.

Here's the code:

	@Override
	public boolean onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) 
	{	
		if(!worldIn.isRemote) 
		{
			NetworkHooks.openGui((ServerPlayerEntity) player, new Furnace(pos, worldIn), buf -> buf.writeBlockPos(pos));
			return true;
		}
		return false;
		
	}

What does this class do?

Oh, my bad. I've given it a very wrong name. It's a class that implements INamedContainerProvider. If you want to see it, here it is:

package mod.sds.terrariamod.inamedcontainerproviders;

import mod.sds.terrariamod.containers.ContainerFurnace;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.entity.player.PlayerInventory;
import net.minecraft.inventory.container.Container;
import net.minecraft.inventory.container.INamedContainerProvider;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.text.ITextComponent;
import net.minecraft.util.text.StringTextComponent;
import net.minecraft.world.World;

public class Furnace implements INamedContainerProvider {

	private BlockPos pos;
	private World world;
	
	public Furnace(BlockPos pos, World world) {
		this.pos = pos;
		this.world = world;
	}
	
	
	@Override
	public Container createMenu(int windowId, PlayerInventory inv, PlayerEntity player) {
		return new ContainerFurnace(windowId, inv, this.world, this.pos);
	}

	@Override
	public ITextComponent getDisplayName() {
		return new StringTextComponent("Furnace Container");
	}

}

I did pass the correct Container Type, right?

[StefanDeSterke]

Ok, so am I just stupid (I think I am :\ ) or doesn't this initialize the field?

		@SubscribeEvent
		public static void FMLClientSetupEvent(FMLClientSetupEvent event)
		{
			
			ScreenManager.registerFactory(ContainerList.furnace, StoneFurnaceGUI::new);
			
		}

How would that initialize the field? You are not assigning it a value there.

Idk, but where would I initialize the field then and with what?

[StefanDeSterke]

You need to set it to your ContainerType instance. You can either do that manually or use @ObjectHolder.

Yay, works!  Thank you all so much for the help
