Class ItemStack

java.lang.Object
net.minecraft.item.ItemStack
All Implemented Interfaces:
ComponentHolder
public final class ItemStack extends Object implements ComponentHolder
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
invalid reference 
#writeNbt(NbtCompound)
, and deserialized with
invalid reference 
#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 NBT
invalid reference 
#hasNbt()
Returns whether the item stack has custom NBT.
Custom NBT
invalid reference 
#getNbt()
Returns the custom NBT of the item stack.
Custom NBT
invalid reference 
#getOrCreateNbt()
Returns the custom NBT of the item stack, or creates one if absent, mutating the stack.
Custom NBT
invalid reference 
#setNbt(NbtCompound)
Sets the custom NBT of the item stack.
Sub Custom NBT
invalid reference 
#getSubNbt(String)
Returns the sub NBT compound at the specified key.
Sub Custom NBT
invalid reference 
#getOrCreateSubNbt(String)
Returns the sub NBT compound at the specified key, or create one if absent, mutating the stack.
Sub Custom NBT
invalid reference 
#removeSubNbt(String)
Removes the sub NBT element at the specified key.
Sub Custom NBT
invalid reference 
#setSubNbt(String, NbtElement)

 ItemStack stack = new ItemStack(Items.APPLE, 64);
 ItemStack newStack = stack.split(10);
 // stack has 54 apples
 // newStack has 10 apples

 ItemStack smallStack = new ItemStack(Items.APPLE, 4);
 ItemStack newSmallStack = smallStack.split(10);
 // smallStack is now empty
 // newSmallStack has 4 apples

    • damage

      public void damage(int amount, Random random, @Nullable @Nullable ServerPlayerEntity player, Runnable breakCallback)
      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.

      When the item "breaks", that is, the stack's damage is equal to or above the maximum damage, breakCallback is run. Callers should decrement the stack size inside the callback.

      Parameters:
      player - the player that damaged the stack, or null if no player is involved
      breakCallback - a callback run when the item "breaks"

    • damage

      public void damage(int amount, LivingEntity entity, EquipmentSlot slot)
      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 send the equipment break status, decrement the stack, and increment Stats.BROKEN if the stack is held by a player.

      Parameters:
