[1.16.5] Help with Capability (Inventory)

Luis_ST · February 14, 2021

I want to overwrite the vanilla ender chest container that the enderchest uses the double chest container.

I looked in the enderchest class vanilla uses PlayerEntity#getInventoryEnderChest

to open the gui so my question how to creat my own enderchest gui with 54 slots?

I know that I have to create my own capability. do I have to create a completely new one or can I use IItemHandler in my TileEntity?

because in the forge doc to capabilities it says that I can use persisting capabilities.

if I can use an existing capability, is this capability unique for each player?

(this is the first time that i use capabilities so i have no experience with them).

So you need to make an interface that extends IItemHandler

do I have to overwrite any method?

So you have to use a capability that's attached to the player.

using the AttachCapabilitiesEvent?

No, you just need a separate interface because you can't have two capabilities with the same interface.

Now i have my custom Interfacce and a class which extends ItemStackHandler and implements my interface

now i have to create a new capability like forge doc:

@CapabilityInject(MyInterface.class)
public static Capability<MyInterface> ITEM_HANDLER_CAPABILITY = null;

but should the class in which i created the capability extends / implements another class

I'm not sure I understand what you mean by this. Which class are you referring to?

I created the classes as described above.

how do I create or register the capability?

This is described in the docs on capabilities.

i just read this, and i created this but i'm not sure if this is correct:

public class ModCapability {
	
	public ModCapability() {
		
		CapabilityManager.INSTANCE.register(IModItemHandler.class, new Storage(), null);
		
	}
	
	private static class Storage implements IStorage<IModItemHandler> {

		@Override
		public INBT writeNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side) {
			
			return null;
			
		}

		@Override
		public void readNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side, INBT nbt) {
			
			
		}
		
	}
	
}

The last parameter for register must not be null.

do i need the factory?

and what's wrong with the factory?

	public ModCapability() {
		
		CapabilityManager.INSTANCE.register(IModItemHandler.class, new Storage(), new Factory());
		
	}
	
	private static class Storage implements IStorage<IModItemHandler> {

		@Override
		public INBT writeNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side) {
			
			return null;
			
		}

		@Override
		public void readNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side, INBT nbt) {
			
			
		}
		
	}
	
	private static class Factory implements Callable<IModItemHandler> {

		@Override
		public IModItemHandler call() throws Exception {
			// what is here wrong?
			return new IModItemHandler();
			
		}
		
	}

The Storage and Factory will most likely go away in the future, it was a flawed concept.

You can just make them throw exceptions.

this is now my complet class is this corect:

	@CapabilityInject(IModItemHandler.class)
	public static Capability<IModItemHandler> ITEM_HANDLER_CAPABILITY = null;
	
	public ModCapability() {
		
		CapabilityManager.INSTANCE.register(IModItemHandler.class, new Storage(), new Factory());
		
	}
	
	private static class Storage implements IStorage<IModItemHandler> {

		@Override
		public INBT writeNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side) {
			
			return null;
			
		}

		@Override
		public void readNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side, INBT nbt) {
			
			
		}
		
	}
	
	private static class Factory implements Callable<IModItemHandler> {

		@Override
		public IModItemHandler call() throws Exception {
			
			return null;
			
		}
		
	}

That's not what I meant by make it throw an exception, but I guess it'll work.

do I have to register the capability or will it be registered automatically when I add it to the player

You already register it...

Another question how to add the extendsEnderChestGui (Generic9x3 ChestContainer) to the Capability (with this two methode \/ )

do I have to synchronize the gui between the server and the client and if so how do I do it since I looked at a few mods on github that use SimpleChannel and an interface is there another way to do this?

		@Override
		public INBT writeNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side) {
			
			CompoundNBT nbt = new CompoundNBT();
			return nbt;
			
		}

		@Override
		public void readNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side, INBT nbt) {
			
			
			
		}

No. Container already does this for you.

okay thanks, if I don't want to overwrite the block (ender chest).

can I open the gui with the PlayerInteractEvent#RightClickBlock (using NetworkHooks)

the container and when closing save them in the capability?

do i have to creat a container with screen or an inventory because the ender chest use an inventory

The Container will already modify the capability (IItemHandler) directly.

so i just have to open the container / inventory and forge saves the gui from automatically?

?

and where i have to put the container/inventory into the capability because when i use the AttachCapabilitiesEvent i got an NullPointerException:

event:

	@SubscribeEvent
	public static void AttachCapabilities(AttachCapabilitiesEvent<Entity> event) {
		
		if (event.getObject() instanceof PlayerEntity && !(event.getObject() instanceof FakePlayer)) {
			
			event.addCapability(new ResourceLocation("cave:extended_enderchest_gui"), new ModCapability.Provider());
			
		}
		
	}

The container is completely unrelated to the capability. The inventory (i.e. IItemHandler) is the capability implementation.

so i have to use IItemHandler to get and open the gui inside there:

NetworkHooks.openGui(serverPlayer, /*here*/, pos);

and:

public class ModCapability {
	
	@CapabilityInject(IModItemHandler.class)
	public static Capability<IModItemHandler> CAPABILITY = null;
	
	public ModCapability() {
		
		CapabilityManager.INSTANCE.register(IModItemHandler.class, new Storage(), new Factory());
		
	}
	
	public static class Storage implements IStorage<IModItemHandler> {
		@Override
		public INBT writeNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side) {
			return null;
		}

		@Override
		public void readNBT(Capability<IModItemHandler> capability, IModItemHandler instance, Direction side, INBT nbt) {
		}
	}
	
	public static class Factory implements Callable<IModItemHandler> {
		@Override
		public IModItemHandler call() throws Exception {
			return null;
		}
	}
	
	public static class Provider implements ICapabilityProvider {

		private final LazyOptional<IModItemHandler> lazyOptional = LazyOptional.of(CAPABILITY::getDefaultInstance);
		
		@Override
		public <T> LazyOptional<T> getCapability(Capability<T> cap, Direction side) {
			
			return cap == CAPABILITY ? lazyOptional.cast() : LazyOptional.empty();

No, you need to implement INamedContainerProvider.

do i only have to implement Named ContainerProvider because i currently extends Chest Container / Container and i think thats wrong

34 minutes ago, diesieben07 said:

Obviously you can't do this if your default factory returns null. Use a normal constructor.

so like this:

	public static class Provider implements ICapabilityProvider {
		
		@Override
		public <T> LazyOptional<T> getCapability(Capability<T> cap, Direction side) {
			
			return null;
			
		}
		
	}

You need both. You need a Container (and the corresponding ContainerType and ScreenFactory) and you need to implement INamedContainerProvider for openGui.

I already have that, but how do I open the container in my event?

what do I have to hand over to the method at "null"?

	@SubscribeEvent
	public static void PlayerInteract(PlayerInteractEvent.RightClickBlock event) {
		
		PlayerEntity player = event.getPlayer();
		BlockPos pos = event.getPos();
		World world = event.getWorld();
		BlockState state = world.getBlockState(pos);
		EnderChestInventory enderChestInventory = player.getInventoryEnderChest();
		
		if (state.getBlock() == Blocks.ENDER_CHEST) {
			
			if (!enderChestInventory.isEmpty()) {
				
				InventoryHelper.dropInventoryItems(world, pos, enderChestInventory);
				
			} else {
				
				if (player instanceof ServerPlayerEntity) {
					
					event.setCanceled(true);
					ServerPlayerEntity serverPlayer = (ServerPlayerEntity) player;
					NetworkHooks.openGui(serverPlayer, null, pos);
					
				}
				
			}
			
		}

A new instance of your INamedContainerProvider implementation.

then like this:

					NetworkHooks.openGui(serverPlayer, new SimpleNamedContainerProvider((id, inventory, playerIn) -> {
						return new ModEnderChestContainer(id, inventory);
					}, ModEnderChestContainer.getContainerName()), pos);

Why do you do this?

This checks whether the player's Enderchest inventory is already in use, as the player may add the mod later. If this is the case,

the existing inventory will be dropped and the new one will be opened with the next click.

Or... you could just make your inventory an extension of the ender chest inventory (just like how chests that are next to each other merge together). That way their existing inventory (if any) stays and if they uninstall the mod at least the "normal" part still stays.

Like I already suggested...

what do I have to change so that it works like a double chest inventory?

Your ICapabiltiyProvider needs a field that holds your capability instance (the inventory). It also needs a field that holds a LazyOptional to be returned from getCapability.

like this?

Yes, but do not make a new LazyOptional every time, like I already told you.

so I store save them in a field?

and how do I add my extended enderchest inventory and that of the enderchest beacuse when i try this:

CombinedInvWrapper invWrapper = new CombinedInvWrapper(inventory);

1. i got an error: "The constructor CombinedInvWrapper(IModItemHandler) is undefined"

2, how to get the ernderchest inventory?

How would you get the ender chest without a player?

i add an constructor an remove the static of the LazyOptional so this is now my Provider:

but i can't combined the Inventories in this way.

Also: You still completely ignore the CombinedInvWrapper that you create.

1. What do I have to do with it or how do I create IItemHandlerModifiable
2. I have to add the container that I have created to my IModItemHandler.

because I have not yet passed anything to the IModItemHandler (it is empty) or I think that it is empty

then i have to creat a field?

I have to do the following:
1. Combination of inventories
2. Creat a IItemHandlerModifiable from the combination
3. Retrun the IItemHandlerModifiable in getCapability
