In this blogpost I will explain the theory behind an ItemStack so you can use it in Visual Bukkit (and Spigot). Let’s start by explaining what an ItemStack actually is:

Itemstacks in Spigot can be easily explained using an hierarchy:

ItemStack
│
├── Material
│
├── Amount
│
└── ItemMeta
├── Display Name
├── Lore
├── Enchantments
├── ItemFlags
├── CustomModelData
├── PersistentDataContainer
├── Unbreakable
└── AttributeModifiers

The itemstack is an object in the SpigotAPI that is created with new Itemstack();. It contains the Material (the item itself), the amount, and the ItemMeta (the propreties).

Element	Type	Description
ItemStack	org.bukkit.inventory.ItemStack	The core object representing an item in Minecraft.
Material	org.bukkit.Material	The type of the item (e.g., DIAMOND_SWORD, APPLE, etc.).
ItemMeta	org.bukkit.inventory.meta.ItemMeta	Metadata associated with an ItemStack. Must be cast to specific meta types for tools, books, etc.
Display Name	String	Custom name for the item shown in-game. Set via ItemMeta#setDisplayName().
Lore	List<String>	Description lines shown below the display name.
Enchantments	Map<Enchantment, Integer>	Enchantments like DAMAGE_ALL, EFFICIENCY, etc.
ItemFlags	Set<ItemFlag>	Flags to hide enchantments, attributes, etc.
CustomModelData	int (optional)	Used for resource packs to apply custom models.
PersistentDataContainer	PersistentDataContainer	Key-value storage for plugin-specific data.
Unbreakable	boolean	If true, the item never takes durability damage.
Amount	int	The quantity of the item (max 64 normally, some exceptions like ender pearls)
AttributeModifiers	Collection<AttributeModifier>	Alters stats like attack speed, damage, etc.

Visual Bukkit

Visual Bukkit offers you two ways of creating an ItemStack. Both options create exactly the same: an itemstack. The chosen option doesn’t affect any possibilities, but rather simplify things.

Option 1:

As I told you before, an ItemStack is an object. To create one, add an ‘New Object‘ from the ItemStack Class. There select new ItemStack(…).

To find all the possible constructors/options, go here.

You can change the displayed name or enchantments via methods. Check out my GUI video here where I create a new ItemStack and change the enchantment via ItemMeta.

Option 2:

Visual Bukkit 6 also offers the ability to create an ItemStack via an orange block. This allows you to change some commonly used parts of the itemmeta like the DisplayName and Lore. Note, that it gives you automatically one bamboo. Or should I say… Cool Bamboo?
