Creating a simple GUI

Setting up the GUI

public class MyGuiClass {
    public static Gui create() {
        return new Gui.Builder(MenuType.GENERIC_9x6, Component.text("title"))
                .addFlags(GuiFlag.DISABLE_ADVANCEMENTS, GuiFlag.DISABLE_ITEM_PICKUP)
                .set(SlotPosition.top(3), GuiButton.of(ItemStack, (view, clickType) -> {
                    // Logic
                }))
                .set(SlotPosition.top(7), GuiButton.of(ItemStack, (view, clickType))
                .build();
    }
}

Afterwards open it any time like so:

GuiManager.open(Player, MyGuiClass.create());

Adding a Paginated Elements Layer:

public static Gui create() {
    int[] slots = {
            1, 2, 4, 5, 6, 8, 9
    };
    PaginatedElements elems = new PaginatedElements(elementsList, slots, GuiView.Segment.TOP);
        
    return new Gui.Builder(MenuType.GENERIC_9x6, Component.text("title"))
            .addFlags(GuiFlag.DISABLE_ADVANCEMENTS, GuiFlag.DISABLE_ITEM_PICKUP)
            .addLayer(elems)
            .set(SlotPosition.top(3), GuiButton.of(ItemStack, (view, clickType) -> {
                // Logic
            }))
            .set(SlotPosition.top(7), GuiButton.of(ItemStack, (view, clickType))
            .build();
}

You can also extend AbstractGui in case you dont want to use builder.

public class MyGui extends AbstractGui {
    public MyGui() {
        super(MenuType.FURNACE, Component.text("title"));
    }
    
    @Override
    protected void init() {
        /*
                set(..)
                addFlag(..)
                etc
         */
    }
    
    @Override
    protected void onOpen() {}
    
    @Override
    protected void onClose() {}
}
