Game.LambdaHack.Server.ItemRev

Creation of items on the server. Types and operations that don't involve server state nor our custom monads.

Documentation

data ItemKnown

The essential item properties, used for the ItemRev hash table from items to their ids, needed to assign ids to newly generated items. All the other meaningul properties can be derived from them. Note: item seed instead of AspectRecord is not enough, becaused different seeds may result in the same AspectRecord and we don't want such items to be distinct in UI and elsewhere.

type ItemRev = HashMap ItemKnown ItemId

Reverse item map, for item creation, to keep items and item identifiers in bijection.

type UniqueSet = EnumSet (ContentId ItemKind)

buildItem :: COps -> AspectRecord -> FlavourMap -> DiscoveryKindRev -> ContentId ItemKind -> Item

Build an item with the given kind and aspects.

newItemKind :: COps -> UniqueSet -> Freqs ItemKind -> AbsDepth -> AbsDepth -> Int -> Frequency (ContentId ItemKind, ItemKind)

Roll an item kind based on given Freqs and kind rarities

newItem :: COps -> Frequency (ContentId ItemKind, ItemKind) -> FlavourMap -> DiscoveryKindRev -> AbsDepth -> AbsDepth -> Rnd (Maybe (ItemKnown, ItemFullKit))

Given item kind frequency, roll item kind, generate item aspects based on level and put together the full item data set.

Item discovery types

data DiscoveryKindRev

The reverse map to DiscoveryKind, needed for item creation. This is total and never changes, hence implemented as vector. Morally, it's indexed by ContentId ItemKind and elements are ItemKindIx.

Instances

Methods

showsPrec :: Int -> DiscoveryKindRev -> ShowS

show :: DiscoveryKindRev -> String

showList :: [DiscoveryKindRev] -> ShowS

Binary DiscoveryKindRev

Defined in Game.LambdaHack.Server.ItemRev

Methods

put :: DiscoveryKindRev -> Put

get :: Get DiscoveryKindRev

putList :: [DiscoveryKindRev] -> Put

emptyDiscoveryKindRev :: DiscoveryKindRev

serverDiscos :: COps -> Rnd (DiscoveryKind, DiscoveryKindRev)

The FlavourMap type

data FlavourMap

Flavours assigned by the server to item kinds, in this particular game. This is total and never changes, hence implemented as vector. Morally, it's indexed by ContentId ItemKind and elements are Flavour.

Instances

Show FlavourMap

Defined in Game.LambdaHack.Server.ItemRev

Methods

showsPrec :: Int -> FlavourMap -> ShowS

show :: FlavourMap -> String

showList :: [FlavourMap] -> ShowS

Binary FlavourMap

Defined in Game.LambdaHack.Server.ItemRev

Methods

put :: FlavourMap -> Put

get :: Get FlavourMap

putList :: [FlavourMap] -> Put

emptyFlavourMap :: FlavourMap

dungeonFlavourMap :: COps -> Rnd FlavourMap

Randomly chooses flavour for all item kinds for this game.
