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 components. 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 components. 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.

Components

Components can be used to store data specific to the item stack. Use ComponentHolder.get(net.minecraft.component.DataComponentType<? extends T>) or ComponentHolder.getOrDefault(net.minecraft.component.DataComponentType<? extends T>, T) to get the component values. Use set(net.minecraft.component.DataComponentType<? super T>, T) or remove(net.minecraft.component.DataComponentType<? extends T>) to set the components.

NBT serialization

An Item Stack can be serialized with encode(RegistryWrapper.WrapperLookup), and deserialized with fromNbt(RegistryWrapper.WrapperLookup, NbtCompound).

    • split

      public ItemStack split(int amount)
      Returns the copy of the stack "split" from the current stack with item count being at most amount.

      Splitting an item stack mutates this stack so that the sum of the stacks' item counts does not change. See the example below: 

      
 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
      Returns:
      the copy of the stack "split" from the current stack with item count being at most amount

    • 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:

      Sets the component type for this item stack to value.

    • apply

      @Nullable public <T, U> T apply(DataComponentType<T> type, T defaultValue, U change, BiFunction<T,U,T> applier)
      Sets the component type by passing the current value and change to applier, then setting its return value as the value. If the component is missing, defaultValue is used as the default.

      In practice, applier is a reference to a method of the component class with one parameter, that returns a new instance of the component with the specific value changed to change. For example, adding a lore can be accomplished by passing reference to LoreComponent.with(net.minecraft.text.Text) and the added lore, like stack.apply(DataComponentTypes.LORE, LoreComponent.DEFAULT, text, LoreComponent::with).

      Returns:
      the previous value set
      See Also:

      This is the same as setting applier.apply(stack.getOrDefault(type, defaultValue), change).
