Description

Game state and persistent player diary types and operations.

Synopsis

Game state

data State Source

The state of a single game that can be saved and restored. It's completely disregarded and reset when a new game is started. In practice, we maintain some extra state (DungeonPerception), but it's only temporary, existing for a single turn and then invalidated.

Constructors

State

Fields

splayer :: ActorId: represents the player-controlled actor
scursor :: Cursor: cursor location and level to return to
sflavour :: FlavourMap: association of flavour to items
sdisco :: Discoveries: items (kinds) that have been discovered
sdungeon :: Dungeon: all dungeon levels
slid :: LevelId: identifier of the current level
scounter :: Int: stores next actor index
srandom :: StdGen: current random generator
sconfig :: CP: this game's config (including initial RNG)
stakeTime :: Maybe Bool: last command unexpectedly took some time
squit :: Maybe (Bool, Status): cause of game end/exit
sfaction :: Id FactionKind: our faction
sdebug :: DebugMode: debugging mode

Accessor

slevel :: State -> Level Source

Get current level from the dungeon data.

stime :: State -> Time Source

Get current time from the dungeon data.

Constructor

defaultState :: CP -> Id FactionKind -> FlavourMap -> Dungeon -> LevelId -> Point -> StdGen -> State Source

Initial game state.

State update

updateCursor :: (Cursor -> Cursor) -> State -> State Source

Update cursor parameters within state.

updateTime :: (Time -> Time) -> State -> State Source

Update time within state.

updateDiscoveries :: (Discoveries -> Discoveries) -> State -> State Source

Update item discoveries within state.

updateLevel :: (Level -> Level) -> State -> State Source

Update level data within state.

updateDungeon :: (Dungeon -> Dungeon) -> State -> State Source

Update dungeon data within state.

Player diary

data Diary Source

The diary contains all the player data that carries over from game to game, even across playing sessions. That includes the last message, previous messages and otherwise recorded history of past games. This can be extended with other data and used for calculating player achievements, unlocking advanced game features and for general data mining, e.g., augmenting AI or procedural content generation.

defaultDiary :: IO Diary Source
