      Sets the type of this item

      Note that in doing so you will reset the MaterialData for this stack.

      type - New type to set the items in this stack to

    • setDurability

      @Deprecated(since="1.13") public void setDurability(short durability)
      Deprecated.
      durability is now part of ItemMeta. To avoid confusion and misuse, getItemMeta(), setItemMeta(ItemMeta) and Damageable.setDamage(int) should be used instead. This is because any call to this method will be overwritten by subsequent setting of ItemMeta which was created before this call.
      Sets the durability of this item
      Parameters:
      durability - Durability of this item

    • getDurability

      Returns:
      Durability of this item

    • getMaxStackSize

      public int getMaxStackSize()
      Get the maximum stack size for this item. If this item has a max stack size component (ItemMeta.hasMaxStackSize()), the value of that component will be returned. Otherwise, this item's Material's default maximum stack size will be returned instead.
      Returns:
      The maximum you can stack this item to.
