Normal GUI

Just a normal GUI without any special functionality.
This example shows how to create one using the GUIBuilder:

KotlinJava

val border = SimpleItem(ItemBuilder(Material.BLACK_STAINED_GLASS_PANE))
val gui = GUIBuilder(GUIType.NORMAL)
    .setStructure(
        "# # # # # # # # #",
        "# . . . . . . . #",
        "# . . . . . . . #",
        "# # # # # # # # #")
    .addIngredient('#', border)
    .build()

Item border = new SimpleItem(new ItemBuilder(Material.BLACK_STAINED_GLASS_PANE));
GUI gui = new GUIBuilder<>(GUIType.NORMAL)
    .setStructure(
        "# # # # # # # # #",
        "# . . . . . . . #",
        "# . . . . . . . #",
        "# # # # # # # # #")
    .addIngredient('#', border)
    .build();
