I know that i have to somehow open gui on server but i dont know what exactly i need to do

Container

public class MyModContainer extends Container implements INamedContainerProvider {
    private  IItemHandler playerInventory;

    protected MyModContainer(int id, PlayerInventory playerInventory) {
        super(RegObj.MOD_CONTAINER.get(), id);

        this.playerInventory = new InvWrapper(playerInventory);
        playerInventory.player.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(h -> {

            addSlot(new SlotItemHandler(h,0,79,18));
        });
        layoutPlayerInventory(7,54);
    }


    private int addSlotRange(IItemHandler handler, int index, int x, int y, int amount, int dx)
    {
        for(int i = 0; i < amount;i++)
        {
            addSlot(new SlotItemHandler(handler,index,x,y));
            x+=dx;
            index++;
        }
        return index;
    }

    private int addSlotBox(IItemHandler handler,int index,int x,int y,int horAmount,int dx,int verAmount,int dy)
    {
        for (int j = 0;j<verAmount;j++)
        {
            index = addSlotRange(handler,index,x,y,horAmount,dx);
            y+=dy;
        }
        return index;
    }

    private void layoutPlayerInventory(int leftCol, int topRow)
    {
        addSlotBox(playerInventory,9,leftCol,topRow,9,18,3,18);
        topRow += 58;
        addSlotRange(playerInventory,0,leftCol,topRow,9,18);
    }


    @Override
    public boolean canInteractWith(PlayerEntity playerIn) {
        return true;
    }

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

    @Nullable
    @Override
    public Container createMenu(int p_createMenu_1_, PlayerInventory p_createMenu_2_, PlayerEntity p_createMenu_3_) {
        return null;
    }
}

 

Screen

public class MyModInv extends ContainerScreen<MyModContainer> {
    private static final int WIDTH =179;
    private static final int HEIGHT =151;

    private ResourceLocation GUI = new ResourceLocation(Main.MODID,"textures/gui/my_inv.png");

    public MyModInv(MyModContainer screenContainer, PlayerInventory inv, ITextComponent titleIn) {
        super(screenContainer, inv, titleIn);
    }


    @Override
    public void render(MatrixStack matrixStack, int mouseX, int mouseY, float partialTicks) {
        super.render(matrixStack, mouseX, mouseY, partialTicks);
        this.renderBackground(matrixStack);
        this.renderHoveredTooltip(matrixStack, mouseX, mouseY);
    }

    @Override
    protected void drawGuiContainerBackgroundLayer(MatrixStack matrixStack, float partialTicks, int x, int y) {
        RenderSystem.color4f(1.0F, 1.0F, 1.0F, 1.0F);
        this.minecraft.getTextureManager().bindTexture(GUI);
        int i = (this.width - WIDTH) / 2;
        int j = (this.height - HEIGHT) / 2;
        this.blit(matrixStack, i, j, 0, 0, WIDTH, HEIGHT);
    }


    @Override
    public boolean isPauseScreen() {
        return false;
    }


}

Override MobEntity#func_230254_b_ and the you can open the container via NetworkHooks.openGui().

How i can get my container here

public ActionResultType func_230254_b_(PlayerEntity playerEntity, Hand hand) {
    if (!this.world.isRemote) {
       String en = getOwner();
       String pl = playerEntity.getScoreboardName();





     if(en.equals(pl))

     {
         NetworkHooks.openGui((ServerPlayerEntity) playerEntity,*container*);
     }
     else
         playerEntity.sendMessage(new TranslationTextComponent("You are not  "+en),Util.DUMMY_UUID);

    }

    return ActionResultType.func_233537_a_(this.world.isRemote);
}

Make a new instance of your container.

like this?

 

NetworkHooks.openGui((ServerPlayerEntity) playerEntity,new MyModContainer(0,playerEntity.inventory));

it stil doest work

i am trying to show my gui by clicking on my entity

public ActionResultType func_230254_b_(PlayerEntity playerEntity, Hand hand) {
    if (!this.world.isRemote) {
       String en = getOwner();
       String pl = playerEntity.getScoreboardName();





     if(en.equals(pl))

     {
         NetworkHooks.openGui((ServerPlayerEntity) playerEntity,new MyModContainer(0,playerEntity.inventory));
     }
     else
         playerEntity.sendMessage(new TranslationTextComponent("You are not  "+en),Util.DUMMY_UUID);

    }

    return ActionResultType.func_233537_a_(this.world.isRemote);
}

where i can get uuid. from player entity? Should my entity implement it?

Is it ok that i am saving a player uuid as a string in datamanager

private static final DataParameter<String> OWNER = EntityDataManager.createKey(MyEntity.class, DataSerializers.STRING);


@OnlyIn(Dist.CLIENT)

public UUID getOwner() {
    return UUID.fromString(this.dataManager.get(OWNER));
}

public void setOwner(UUID name) {
    this.dataManager.set(OWNER ,name.toString());

}

So what needs to be implemented? My Entity?

• openGui requires an INamedContainerProvider. It looks like you made your container implement that, which doesn't make much sense.

What should implement INamedContainerProvider 

I dont quite understand what you mean by this. I created a new class. 

 

 

NetworkHooks.openGui((ServerPlayerEntity) playerEntity,new MyModContainer(0,new anonymousInnerClass()
{

},playerEntity.inventory));

 

 

public class anonymousInnerClass implements INamedContainerProvider {

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

    @Nullable
    @Override
    public Container createMenu(int id, PlayerInventory playerInventory, PlayerEntity playerEntity) {
        return new MyModContainer(id,playerInventory);
    }
}

I ve seen an example of it but i dont understand how i can apply this to my problem. Do I need to call createmenu from new class in networkhooks.opengui method? 

No, it is looking for a container provider, so just pass an instance of it.

is it correct
 

INamedContainerProvider in = new INamedContainerProvider() {
    @Override
    public ITextComponent getDisplayName() {
        return new StringTextComponent("Name");
    }

    @Nullable
    @Override
    public Container createMenu(int id, PlayerInventory playerInventory, PlayerEntity playerEntity) {
        return new MyModContainer(id,playerInventory);
    }
};

         if(en.equals(pl))

         {
             NetworkHooks.openGui((ServerPlayerEntity) playerEntity, in,(Consumer<PacketBuffer>) playerEntity.inventory);
         }
         else
             playerEntity.sendMessage(new TranslationTextComponent("You are not  "+en),Util.DUMMY_UUID);

        }

With out it java gave an error "Cant resolve method openGui". What i did  wrong here?

Ok i messed up few things, idk where did i get a player inventory parameter in openGui. So thanks it's working now
But how i can correctly get the entity inside the container class to get capabilities to add a slot. I know how to do it with the player i can just get the player from the player inventory but with a mob i am not sure. Should i get the entity from world somehow?
 

is it correct?

//MyModEntity     
public ITextComponent getDisplayName() {
         return new StringTextComponent("Name");
     }

     @Nullable
     @Override
     public Container createMenu(int id, PlayerInventory playerInventory, PlayerEntity playerEntity) {
         return new MyModContainer(id,playerInventory, world);
     }
 };


 PacketBuffer buf = new PacketBuffer(Unpooled.buffer());
 buf.writeVarInt(this.getEntityId());
NetworkHooks.openGui((ServerPlayerEntity) playerEntity,iNamedContainerProvider,(Consumer<PacketBuffer> buf);

 

and how can i get it in my container class

//MyModContainer
world.getEntityByID().getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(h -> {

    addSlot(new SlotItemHandler(h,0,79,18));
});

In my IContainerFactory? Where i can get it in my container class 

I don't understand. Where i should have container factory

Thanks it seems to be working. 
But i didnt understand one thing. if this line sending the EntityId to my container

return new MyModContainer(id,playerInventory, world,extraDataWriter);

so what do that line with EntityId 

NetworkHooks.openGui((ServerPlayerEntity) playerEntity,iNamedContainerProvider, buf -> buf.writeInt(getEntityId()));

 

PacketBuffer extraDataWriter = new PacketBuffer(Unpooled.buffer());

 extraDataWriter.writeInt(getEntityId());
 INamedContainerProvider iNamedContainerProvider = new INamedContainerProvider() {
     @Override
     public ITextComponent getDisplayName() {
         return new StringTextComponent("loh");
     }

     @Nullable
     @Override
     public Container createMenu(int id, PlayerInventory playerInventory, PlayerEntity playerEntity) {
         return new MyModContainer(id,playerInventory, world,extraDataWriter);
     }
 };



NetworkHooks.openGui((ServerPlayerEntity) playerEntity,iNamedContainerProvider, buf -> buf.writeInt(getEntityId()));

why

I get it but my container have a data parametr now
 

protected MyModContainer(int id, PlayerInventory playerInventory,World world,PacketBuffer data) {
    super(RegObj.MOD_CONTAINER.get(), id);

    this.playerInventory = new InvWrapper(playerInventory);


    world.getEntityByID( data.readInt()).getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(h -> {

        addSlot(new SlotItemHandler(h,0,79,18));
    });
    layoutPlayerInventory(7,54);
}

 

and my anonymous inner class asks for data parametr  too. if i'll leave it null container wont work

INamedContainerProvider iNamedContainerProvider = new INamedContainerProvider() {
    @Override
    public ITextComponent getDisplayName() {
        return new StringTextComponent("loh");
    }

    @Nullable
    @Override
    public Container createMenu(int id, PlayerInventory playerInventory, PlayerEntity playerEntity) {
        return new MyModContainer(id,playerInventory, world,extraDataWriter);
    }
};

how else i can get my id. 

protected MyModContainer(int id, PlayerInventory playerInventory,World world,PacketBuffer data) {
    super(RegObj.MOD_CONTAINER.get(), id);

    this.playerInventory = new InvWrapper(playerInventory);


    world.getEntityByID( data.readInt()).getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent(h -> {

        addSlot(new SlotItemHandler(h,0,79,18));
    });
    layoutPlayerInventory(7,54);
}

 

 

public static final RegistryObject<ContainerType<MyModContainer>> MOD_CONTAINER = CONTAINERS.register("my_con", () -> IForgeContainerType.create((windowId, inv,data) -> {
            World world = inv.player.getEntityWorld();
            return new MyModContainer(windowId, inv,world,data);
        }));

Well, since 

    public Container createMenu(int id, PlayerInventory playerInventory, PlayerEntity playerEntity <--------) {
        return new MyModContainer(id,playerInventory, world,extraDataWriter);
    }

you already have the player, why don't you just pass the player in?

Also getEntityByID is using entityID not UUID, use ServerWorld#getEntityByUuid/getPlayerByUuid although it is not necessary because you've got the player already.
