Class ItemStack

java.lang.Object
net.minecraft.item.ItemStack
public final class ItemStack extends Object
Represents a stack of items. This is a data container that holds the item count and the stack's NBT. Logics for items (such as the action for using it) are delegated to the stack's logic container, Item. Instances can be created using one of the constructors and are usually stored in an Inventory.

Item stacks should never be compared using == operator or equals method. This also means they cannot be used as a map key. To check if an item stack is of a certain item, use isOf(Item). To compare two item stacks, use areItemsEqual(net.minecraft.item.ItemStack, net.minecraft.item.ItemStack) to check the item only, or areEqual(net.minecraft.item.ItemStack, net.minecraft.item.ItemStack) to also check the item count and the NBT. Use isEmpty() to check if an item stack is empty instead of doing stack == ItemStack.EMPTY.

When storing an item stack in an inventory or other places, make sure that an instance is never stored in multiple places. When two inventories hold the same instance, it will duplicate the item stack (and become two instances) when one is saved and reloaded.

NBT operations

NBT serialization

An Item Stack can be serialized with writeNbt(NbtCompound), and deserialized with fromNbt(NbtCompound).
Serialized NBT Structure
KeyTypePurpose
idNbtStringThe identifier of the item.
CountNbtByteThe count of items in the stack.
tagNbtCompoundThe item stack's custom NBT.

Custom NBT

The item stack's custom NBT may be used to store extra information, like the block entity data for shulker boxes, or the damage of a damageable item, etc.

Various methods are available to interact with the custom NBT, some methods might refer to a "sub NBT", a sub NBT is a child element of the custom NBT.

Custom NBT operations
CategoryMethodSummary
Custom NBThasNbt()Returns whether the item stack has custom NBT.
Custom NBTgetNbt()Returns the custom NBT of the item stack.
Custom NBTgetOrCreateNbt()Returns the custom NBT of the item stack, or creates one if absent, mutating the stack.
Custom NBTsetNbt(NbtCompound)Sets the custom NBT of the item stack.
Sub Custom NBTgetSubNbt(String)Returns the sub NBT compound at the specified key.
Sub Custom NBTgetOrCreateSubNbt(String)Returns the sub NBT compound at the specified key, or create one if absent, mutating the stack.
Sub Custom NBTremoveSubNbt(String)Removes the sub NBT element at the specified key.
Sub Custom NBTsetSubNbt(String, NbtElement)Sets the sub NBT element at the specified key.

    • damage

      public boolean damage(int amount, Random random, @Nullable @Nullable ServerPlayerEntity player)
      Damages this item stack. This method should be used when a non-entity, such as a dispenser, damages the stack. This does not damage non-damageable stacks, and the unbreaking enchantment is applied to amount before damaging.

      If player is not null, this triggers Criteria.ITEM_DURABILITY_CHANGED.

      This method does not decrement the item count when the item "breaks". Callers should check the returned value and decrement themselves.

      Parameters:
      player - the player that holds the stack to be damaged, or null if inapplicable
      Returns:
      whether the stack's damage is equal to or above the maximum damage (i.e. whether the item is "broken")

    • damage

      public <T extends LivingEntity> void damage(int amount, T entity, Consumer<T> breakCallback)
      Damages this item stack. This method should be used when an entity, including a player, damages the stack. This does not damage non-damageable stacks, and the unbreaking enchantment is applied to amount before damaging. Additionally, if entity is a player in creative mode, the stack will not be damaged.

      If entity is a player, this triggers Criteria.ITEM_DURABILITY_CHANGED.

      If the stack's damage is equal to or above the maximum damage (i.e. the item is "broken"), this will call breakCallback, decrement the stack, and increment Stats.BROKEN if the stack is held by a player. The callback should call LivingEntity.sendEquipmentBreakStatus(net.minecraft.entity.EquipmentSlot) or LivingEntity.sendToolBreakStatus(net.minecraft.util.Hand).

      Parameters:
      entity - the entity that holds the stack to be damaged
      breakCallback - the callback that takes the entity holding the stack and is executed when the item breaks
