@SubscribeEvent
    public static void gauntletGUI(final TickEvent.PlayerTickEvent event) {
        PlayerEntity player = event.player;
        ItemStack stack = event.player.getMainHandItem();

        if (keyOpenGauntlet.isDown() && keyOpenGauntlet.consumeClick() && stack.getItem().equals(ItemInit.INFINITY_GAUNTLET.get())) {
            Main.NETWORK.sendToServer(new InputMessage(stack));
        }
    }

This is the event

 

    public static void handle(InputMessage message, Supplier<NetworkEvent.Context> contextSupplier) {
        NetworkEvent.Context context = contextSupplier.get();
        context.enqueueWork( () ->
                {
                    ServerPlayerEntity player = context.getSender();
                    INamedContainerProvider ncp = new InfinityGauntlet.InfinityGauntletContainerProvider(player.getMainHandItem().getItem(), message.stack);
                    NetworkHooks.openGui(player, ncp);
                }
                );
        context.setPacketHandled(true);

    }

This opens the GUI.

 

So the problem is that when I press the key in this case is B the GUI opens and instantly closes.

are you sure stillValid returns true, use debugger to check?

because of the error you described I would say it returns false

It was that, thanks 

Ok, so I have put this code and it doesn't work, I have to forms of opening the GUI one is on the useOn  void of the item and this  form work but the other form is to press 'B' but when the GUI opens it closes. If I put "return true;" in stillValid the GUI didn't close so it's obvious that the problem is there but I dont understand why 

    @Override
    public boolean stillValid(PlayerEntity player) {
        return (player.getMainHandItem().equals(heldItem));

    }

 

stillValid() runs on the server, where are you storing "heldItem" when you press B?

ItemStack does not override equals, this means the == operator is used,
you need to use IForgeItemStack#equals (requires an ItemStack and a boolean)

or you check the Item of the ItemStack, therefore you can use a instanceof check, equals or the == operator depends on your purpose

There is defined the heldItem https://github.com/Manueh333/Marvel-MOD/blob/1.16.5/src/main/java/manueh/marvel_themod/common/containers/InfinityGauntletContainer.java#L42
This is the one that works https://github.com/Manueh333/Marvel-MOD/blob/1.16.5/src/main/java/manueh/marvel_themod/common/items/InfinityGauntlet.java#L259-L260

This don't work https://github.com/Manueh333/Marvel-MOD/blob/1.16.5/src/main/java/manueh/marvel_themod/client/ClientEvents.java#L88

when exactly should the player be able to open the container?
please be as detailed as possible

is the Packet received on server and how did you test if it works?

I tested it with a breakpoint and pressing B at the game

You said I have to use a IForgeItemStack#equals with a ItemStack and a boolean so how?

Edited July 6, 20223 yr by Grookey

 

You want to retrieve the held item on the server.

Instead you are retrieving it on the client which will not be the same item stack as the held item on the server. It will be a copy. So == will be false.

 

But I think you actually just need the following

        return (player.getMainHandItem().sameItem(heldItem));

to check the items are the same type. You are not interested in the stack count or tags?

Actually, yes the Item is a container that contains items so its important that

 

But I tried and It worked

Also it would be good to make the item cant be moved in the inventory when my GUI is opened is there any form to do this?

Edited July 6, 20223 yr by Grookey

Then use one of the ItemStack.matches() or the equals(ItemStack, boolean) defined by the IForgeItemStack interface.

I am not sure of your requirements so you will have to figure out which one yourself 🙂

I thought that I need the tags but not because the item contain items if you add or remove some of the item it closes the GUI and the content of the container is not updated so I finally used this code

Any of the codes worked for me because when i change a Item of the inside of the container it closes and not updates, and like after the problem is only when I use the key B to open the GUI

    @SubscribeEvent
    public static void gauntletGUI(TickEvent.PlayerTickEvent event) {
        PlayerEntity player = event.player;
        ItemStack stack = event.player.getItemBySlot(EquipmentSlotType.MAINHAND);

        if (keyOpenGauntlet.isDown() && keyOpenGauntlet.consumeClick() && stack.getItem().equals(ItemInit.INFINITY_GAUNTLET.get())) {
            Main.NETWORK.sendToServer(new InputMessage(stack));
        }
    }

KeyBindings are client side only, you need to use TickEvent.ClientTickEvent instead

why did you call KeyBinding#consumeClick, you should only check KeyBinding#isDown?

last but not least i would recommend you to check the Item also on server side (in the handle method of the Message), since you should never trust the client

In ClickTickEvent i dont know how to get the player

            INamedContainerProvider ncp = new InfinityGauntlet.InfinityGauntletContainerProvider((InfinityGauntlet) gauntlet.getItem(), gauntlet);
            NetworkHooks.openGui(player, ncp);
            context.setPacketHandled(false);
        }


    }

You were right I check the item on the server and this code works 
Thanks

on client you always can use Minecraft.getInstance(), then you be able to get the local player

            if (keyOpenGauntlet.isDown() && stack.getItem().equals(ItemInit.INFINITY_GAUNTLET.get())) {
                Main.NETWORK.sendToServer(new InputMessage(stack));
            }
        }

    }

It works. Thanks!

Oh I forget to remove that part hehe
