invalidateBfs :: ActorId -> EnumMap ActorId (Bool, Array BfsDistance, Point, Int, Maybe [Point]) -> EnumMap ActorId (Bool, Array BfsDistance, Point, Int, Maybe [Point])

getCacheBfsAndPath :: forall m. MonadClient m => ActorId -> Point -> m (Array BfsDistance, Maybe [Point])

Get cached BFS data and path or, if not stored, generate, store and return. Due to laziness, they are not calculated until needed.

getCacheBfs :: MonadClient m => ActorId -> m (Array BfsDistance)

accessCacheBfs :: MonadClient m => ActorId -> Point -> m (Maybe Int)

unexploredDepth :: MonadClient m => m (Int -> LevelId -> Bool)

closestUnknown :: MonadClient m => ActorId -> m (Maybe Point)

Closest reachable unknown tile position, if any.

closestSuspect :: MonadClient m => ActorId -> m [Point]

Closest (wrt paths) suspect tile.

closestSmell :: MonadClient m => ActorId -> m [(Int, (Point, SmellTime))]

Finds smells closest to the actor, except under the actor.

furthestKnown :: MonadClient m => ActorId -> m Point

Furthest (wrt paths) known position.

closestTriggers :: MonadClient m => Maybe Bool -> ActorId -> m (Frequency Point)

Closest (wrt paths) triggerable open tiles. The level the actor is on is either explored or the actor already has a weapon equipped, so no need to explore further, he tries to find enemies on other levels.

closestItems :: MonadClient m => ActorId -> m [(Int, (Point, Maybe ItemBag))]

Closest (wrt paths) items and changeable tiles (e.g., item caches).

closestFoes :: MonadClient m => [(ActorId, Actor)] -> ActorId -> m [(Int, (ActorId, Actor))]

Closest (wrt paths) enemy actors.
