I want to create an item with inventory in [1.12.2]. What should I do now? I would like to know sites that can be referenced.

I especially want to know the flow from opengui.

Please elaborate. What are you trying to describe by "the flow"?

I am sorry. I am not goot at English. I want to know the "series of flows" from opengui.

I am Japanese. So it is “流れ(nagare)” when expressed in Japanese.

I want to know about the event after right-clicking an item. The ”流れ" is about events.

I think OP means the workflow of opening an inventory that has a container.

Basically “how should I achieve creating an item that opens up an inventory”?

I want to make an item that opens an inventory with a slot by right clicking.

I make a chest program with reference. However, since the chest is Minecraft, I don't know how to use Forge's IItemHandler.

Temporarily, the item name is a backpack.

public class GuiHandler implements IGuiHandler
{
    @Override
    public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
    {
        if (ID == 1)
        {
            return new ContainerBackPack(player.inventory);        
		}
        return null;
    }

    @Override
    public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
    {
        if (ID == 1)
        {
            return new GuiBackPack(player.inventory);
        }
        return null;
    }
}

public class GuiBackPack extends GuiContainer
{
    private static final ResourceLocation TEXTURE = new ResourceLocation("textures/gui/container/generic_54.png");

	public GuiBackPack(InventoryPlayer inventory)
	{
		super(new ContainerBackPack(inventory));
        this.ySize = 222;
	}

	@Override
	protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY)
	{
		GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
        this.mc.getTextureManager().bindTexture(TEXTURE);
        int k = (this.width - this.xSize) / 2;
        int l = (this.height - this.ySize) / 2;
        this.drawTexturedModalRect(k, l, 0, 0, this.xSize, this.ySize);
	}

And now I'm wondering how to make "ContainerBackPack".

Is it public class ContainerChest extends Container?
