type ItemMap = IntMap ([Item], [Item])Source

Actual and remembered item lists on map tiles.

type TileMap = Array Point TileKind Source

Tile kinds on the map.

data Level Source

A single, inhabited dungeon level.

Level update

updateHeroes :: (Party -> Party) -> Level -> Level Source

Update the hero and monster maps.

updateMonsters :: (Party -> Party) -> Level -> Level Source

Update the hero and monster maps.

updateHeroItem :: (PartyItem -> PartyItem) -> Level -> Level Source

Update the hero items and monster items maps.

updateMonItem :: (PartyItem -> PartyItem) -> Level -> Level Source

Update the hero items and monster items maps.

updateSmell :: (SmellMap -> SmellMap) -> Level -> Level Source

Update the smell map.

updateIMap :: (ItemMap -> ItemMap) -> Level -> Level Source

Update the items on the ground map.

updateLMap :: (TileMap -> TileMap) -> Level -> Level Source

Update the tile and remembered tile maps.

updateLRMap :: (TileMap -> TileMap) -> Level -> Level Source

Update the tile and remembered tile maps.

dropItemsAt :: [Item] -> Point -> Level -> Level Source

Place all items on the list at a location on the level.

Level query

at :: Level -> Point -> Id TileKind Source

Query for actual and remembered tile kinds on the map.

rememberAt :: Level -> Point -> Id TileKind Source

Query for actual and remembered tile kinds on the map.

atI :: Level -> Point -> [Item]Source

Query for actual and remembered items on the ground.

rememberAtI :: Level -> Point -> [Item]Source

Query for actual and remembered items on the ground.

stdRuleset :: Ops RuleKind -> RuleKind Source

The standard ruleset used for level operations.

accessible :: COps -> Level -> Point -> Point -> Bool Source

Check whether one location is accessible from another, using the formula from the standard ruleset.

openable :: Ops TileKind -> Level -> SecretStrength -> Point -> Bool Source

Check whether the location contains a door of secrecy lower than k and that can be opened according to the standard ruleset.

findLoc :: TileMap -> (Point -> Id TileKind -> Bool) -> Rnd Point Source

Find a random location on the map satisfying a predicate.

findLocTry Source

Arguments

:: Int	the number of tries
-> TileMap	look up in this map
-> [Point -> Id TileKind -> Bool]	predicates to satisfy
-> Rnd Point

Try to find a random location on the map satisfying the conjunction of the list of predicates. If the premitted number of attempts is not enough, try again the same number of times without the first predicate, then without the first two, etc., until only one predicate remains, at which point try as many times, as needed.
