LambdaHack- A game engine library for roguelike dungeon crawlers

Safe HaskellNone




Actors in the game: heroes, monsters, etc. No operation in this module involves the State or Action type.


Actor identifiers and related operations

data ActorId Source

A unique identifier of an actor in the dungeon.

monsterGenChance :: AbsDepth -> AbsDepth -> Int -> Int -> Rnd Bool Source

Chance that a new monster is generated. Currently depends on the number of monsters already present, and on the level. In the future, the strength of the character and the strength of the monsters present could further influence the chance, and the chance could also affect which monster is generated. How many and which monsters are generated will also depend on the cave kind used to build the level.

partActor :: Actor -> MU.Part Source

The part of speech describing the actor.

partPronoun :: Actor -> MU.Part Source

The part of speech containing the actor pronoun.

The Actor type

data Actor Source

Actor properties that are changing throughout the game. If they are dublets of properties from ActorKind, they are usually modified temporarily, but tend to return to the original value from ActorKind over time. E.g., HP.

individual map symbol

individual name

individual pronoun

bcolor :: !Color

individual map color Resources

btime :: !Time

HP delta this turn * 1M

bcalm :: !Int64

current calm * 1M

bcalmDelta :: !ResDelta

calm delta this turn * 1M Location

bpos :: !Point

current position

boldpos :: !Point

previous position

braced :: Actor -> Bool Source

waitedLastTurn :: Actor -> Bool Source

The actor waited last turn.

unoccupied :: [Actor] -> Point -> Bool Source

Checks for the presence of actors in a position. Does not check if the tile is walkable.


type ActorDict = EM.EnumMap ActorId Actor Source

All actors on the level, indexed by actor identifier.

smellTimeout :: Delta Time Source

How long until an actor's smell vanishes from a tile.

mapActorItems_ :: Monad m => (ItemId -> ItemQuant -> m a) -> Actor -> m () Source
