ItemInstance

Remarks

A bank of ten thousand items is a real number. Doc 28 § Items: an instance carrying a materialised stat block is fifty times the memory for data that is a pure function of the seed. So an instance is a definition, a stack count, a durability, a roll seed and a bound state — and every affix, every stat and every tooltip line is recomputed from those when somebody actually looks.

⚠ The seed is the item's identity as far as its affixes are concerned. Two instances with the same definition and the same seed roll identically, in every process, for ever — which is what makes a trade window, a client's tooltip and a realm's damage calculation agree without any of them sending a stat block.

⚠ What is not here is anything of variable size — no socketed gems, no custom name, no transmog override. Those are per-copy extras that most copies do not have, and a side table kept by whatever owns the instance is where they belong; putting them here would cost every one of the ten thousand.

Fields and properties (8)

• public static ItemInstance Empty

  The empty slot. A definition of None is nothing at all.

• public DefId Definition

  Which item this is a copy of.

• public uint Seed

  What its affixes rolled from. Zero is an unrolled copy — a stack of ore.

• public ushort Stack

  How many are in this stack. Never zero for a real instance.

• public ushort Durability

  How much wear is left. Meaningless when the definition is indestructible.

• public ItemBinding Binding

  Whether it is still tradeable, and what will stop it being so.

• public bool IsSome

  Whether this is a real item rather than an empty slot.

• public bool IsTradeable

  Whether it can still change hands.

Methods (4)

• public static ItemInstance Of(DefId definition, int stack = 1)

  Makes a stack of something with no affixes to roll.

• public ItemInstance WithStack(int stack)

  The same item with a different stack count.

• public ItemInstance Bind()

  The same item, bound.

• public override string ToString()

  Returns the fully qualified type name of this instance.
