public class Item extends Object implements ToggleableFeature, ItemConvertible
An item usable by players and other entities.

Like Block, this class handles logics for a type of item, and does not hold any data. Any data about a particular stack of item in a world, such as item count, is held by an ItemStack which represents a stack of specific item. Therefore, there is one - and only one - instance of Item for one item (like apples, oak planks, etc), while there can be infinite amounts of ItemStack instances. This also means that items themselves cannot hold NBT data.

Items with no custom behavior, like diamonds, can call the constructor of Item directly. If a custom behavior is needed, this should be subclassed. Items also have to be registered in the Registries.ITEM registry.

Many methods of this class are called on both the logical client and logical server, so take caution when using those methods. The logical side can be checked using World.isClient. See also the Fabric Wiki article. It is also important that methods that take LivingEntity as an argument can be called by non-players (such as foxes eating food), which causes a crash if the code performs unchecked casting.

    • getMiningSpeedMultiplier

      public float getMiningSpeedMultiplier(ItemStack stack, BlockState state)
      Returns the multiplier applied to the mining speed of stack when mining state.

      The default value is 1.0f. Returning larger integer will cause the block to be mined faster. Enchantments, status effects, and other effects that affect mining speed are instead handled in PlayerEntity.getBlockBreakingSpeed(net.minecraft.block.BlockState).

      Returns:

    • use

      public TypedActionResult<ItemStack> use(World world, PlayerEntity user, Hand hand)
      Called when the player uses (or starts using) the item. The use action, by default, is bound to the right mouse button. This method checks the player's hunger when the item is a food, and will pass in all other cases by default.

      If the item can be used for multiple ticks, then this will only be called when the player starts using it. After that, usageTick(net.minecraft.world.World, net.minecraft.entity.LivingEntity, net.minecraft.item.ItemStack, int) is called every tick until the player finishes using the item.

      This method is called on both the logical client and logical server, so take caution when overriding this method. The logical side can be checked using world.isClient().

      Parameters:
      world - the world the item was used in
      user - the player who used the item
      hand - the hand used
      Returns:
      a typed action result that specifies whether using the item was successful. The action result contains the new item stack that the player's hand will be set to.

    • finishUsing

      public ItemStack finishUsing(ItemStack stack, World world, LivingEntity user)
      Called when an entity finishes using the item, such as eating food or drinking a potion. This method handles eating food by default.

      This method is called on both the logical client and logical server, so take caution when overriding this method. The logical side can be checked using World.isClient.

      user might not be a player in some cases. For example, this occurs when a fox eats food or when a wandering trader drinks milk.

      public boolean onClicked(ItemStack stack, ItemStack otherStack, Slot slot, ClickType clickType, PlayerEntity player, StackReference cursorStackReference)
      Called when the item at slot gets clicked by the cursor holding otherStack.

      stack - the slot's stack
      otherStack - the stack the cursor holds
      slot - the clicked slot

      public boolean isSuitableFor(BlockState state)
      Determines whether this item can be used as a suitable tool for mining the specified block. Depending on block implementation, when combined together, the correct item and block may achieve a better mining speed and yield drops that would not be obtained when mining otherwise.

      Note that this is not the only way to achieve "effectiveness" when mining. Other items, such as shears on string, may use their own logic and calls to this method might not return a value consistent to this rule for those items.
