func (*Items) ItemByServerID

func (otb *Items) ItemByServerID(serverID uint16) (*Item, error)

ItemByServerID allows lookup of an item stored in an items.otb file based on its persistent 'server' ID, which stays fixed between versions, and is used by the server-side data storage, by map files, etc.
