AddStack adds another stack to the stack and returns both stacks. The first stack returned will have as many items in it as possible to fit in the stack, according to a max count of either 64 or otherwise as returned by Item.MaxCount(). The second stack will have the leftover items: It may be empty if the count of both stacks together don't exceed the max count. If the two stacks are not comparable, AddStack will return both the original stack and the stack passed.

func (Stack) AttackDamage 

func (s Stack) AttackDamage() float64

AttackDamage returns the attack damage of the stack. By default, the value returned is 2.0. If the item held implements the item.Weapon interface, this damage may be different.

func (Stack) Comparable 

func (s Stack) Comparable(s2 Stack) bool

Comparable checks if two stacks can be considered comparable. True is returned if the two stacks have an equal item type and have equal enchantments, lore and custom names, or if one of the stacks is empty.

func (Stack) Count 

func (s Stack) Count() int

Count returns the amount of items that is present on the stack. The count is guaranteed never to be negative.

func (Stack) CustomName 

func (s Stack) CustomName() string

CustomName returns the custom name set for the Stack. An empty string is returned if the Stack has no custom name set.

func (Stack) Damage 

func (s Stack) Damage(d int) Stack

Damage returns a new stack that is damaged by the amount passed. (Meaning, its durability lowered by the amount passed.) If the item does not implement the Durable interface, the original stack is returned. The damage passed may be negative to add durability. If the final durability reaches 0 or below, the item returned is the resulting item of the breaking of the item. If the final durability reaches a number higher than the maximum durability, the stack returned will get the maximum durability.

func (Stack) Durability 

func (s Stack) Durability() int

Durability returns the current durability of the item stack. If the item is not one that implements the Durable interface, BaseDurability will always return -1. The closer the durability returned is to 0, the closer the item is to breaking.

func (Stack) Empty 

func (s Stack) Empty() bool

Empty checks if the stack is empty (has a count of 0).

func (Stack) Enchantment 

func (s Stack) Enchantment(enchant Enchantment) (Enchantment, bool)

Enchantment attempts to return an enchantment set to the Stack using Stack.WithEnchantment(). If an enchantment is found, the enchantment and the bool true is returned.

func (Stack) Enchantments 

func (s Stack) Enchantments() []Enchantment

Enchantments returns an array of all Enchantments on the item.

func (Stack) Equal 

func (s Stack) Equal(s2 Stack) bool

Equal checks if the two stacks are equal. Equal is equivalent to a Stack.Comparable check while also checking the count.

func (Stack) Grow 

func (s Stack) Grow(n int) Stack

Grow grows the Stack's count by n, returning the resulting Stack. If a positive number is passed, the stack is grown, whereas if a negative size is passed, the resulting Stack will have a lower count. The count of the returned Stack will never be negative.

func (Stack) Item 

func (s Stack) Item() world.Item

Item returns the item that the stack holds. If the stack is considered empty (Stack.Empty()), Item will always return nil.

func (Stack) Lore 

func (s Stack) Lore() []string

Lore returns the lore set for the Stack. If no lore is present, the slice returned has a len of 0.

func (Stack) MaxCount 

func (s Stack) MaxCount() int

MaxCount returns the maximum count that the stack is able to hold when added to an inventory or when added to an item entity.

func (Stack) MaxDurability 

func (s Stack) MaxDurability() int

MaxDurability returns the maximum durability that the item stack is able to have. If the item does not implement the Durable interface, MaxDurability will always return -1.

func (Stack) String 

func (s Stack) String() string

String implements the fmt.Stringer interface.

func (Stack) Value 

func (s Stack) Value(key string) (val interface{}, ok bool)

Value attempts to return a value set to the Stack using Stack.WithValue(). If a value is found by the key passed, it is returned and ok is true. If not found, the value returned is nil and ok is false.

func (Stack) WithCustomName 

func (s Stack) WithCustomName(a ...interface{}) Stack

WithCustomName returns a copy of the Stack with the custom name passed. The custom name is formatted according to the rules of fmt.Sprintln.

func (Stack) WithDurability 

func (s Stack) WithDurability(d int) Stack

WithDurability returns a new item stack with the durability passed. If the item does not implement the Durable interface, WithDurability returns the original stack. The closer the durability d is to 0, the closer the item is to breaking. If a durability of 0 is passed, a stack with the item type of the BrokenItem is returned. If a durability is passed that exceeds the maximum durability, the stack returned will have the maximum durability.

func (Stack) WithEnchantment 

func (s Stack) WithEnchantment(ench Enchantment) Stack

WithEnchantment returns the current stack with the passed enchantment. If the enchantment is not compatible with the item stack, it will not be applied and will return the original stack.

func (Stack) WithLore 

func (s Stack) WithLore(lines ...string) Stack

WithLore returns a copy of the Stack with the lore passed. Each string passed is put on a different line, where the first string is at the top and the last at the bottom. The lore may be cleared by passing no lines into the Stack.

func (Stack) WithValue 

func (s Stack) WithValue(key string, val interface{}) Stack

WithValue returns the current Stack with a value set at a specific key. This method may be used to associate custom data with the item stack, which will persist through server restarts. The value stored may later be obtained by making a call to Stack.Value().

WithValue may be called with a nil value, in which case the value at the key will be cleared.

WithValue stores values by encoding them using the encoding/gob package. Users of WithValue must ensure that their value is valid for encoding with this package.

func (Stack) WithoutEnchantment 

func (s Stack) WithoutEnchantment(enchant Enchantment) Stack

WithoutEnchantment returns the current stack but with the passed enchantment removed.
