Representation of dice for parameters scaled with current level depth.

Frequency distribution for casting dice scaled with level depth

data Dice

Dice for parameters scaled with current level depth. To the result of rolling the first set of dice we add the second, scaled in proportion to current depth divided by maximal dungeon depth. The result if then multiplied by the scale --- to be used to ensure that dice results are multiples of, e.g., 10. The scale is set with |*|.

diceConst :: Dice -> SimpleDice

diceLevel :: Dice -> SimpleDice

diceMult :: Dice -> Int

(|*|) :: Dice -> Int -> Dice infixl 5

Multiplying the dice, after all randomness is resolved, by a constant. Infix declaration ensures that 1 + 2 |*| 3 parses as (1 + 2) |*| 3.

d :: Int -> Dice

A single simple dice.

ds :: Int -> Dice

Dice scaled with level.

dl :: Int -> Dice

intToDice :: Int -> Dice

maxDice :: Dice -> Int

Maximal value of dice. The scaled part taken assuming maximum level.

minDice :: Dice -> Int

Minimal value of dice. The scaled part ignored.

meanDice :: Dice -> Int

Mean value of dice. The level-dependent part is taken assuming the highest level, because that's where the game is the hardest. Assumes the frequencies are not null.

reduceDice :: Dice -> Maybe Int

Dice for rolling a pair of integer parameters representing coordinates.

data DiceXY

Dice for rolling a pair of integer parameters pertaining to, respectively, the X and Y cartesian 2D coordinates.
