Features

Dice Rolling

Dice rolling is very simple:

Single Die:

using RPGHelper

result = roll(d10)
sumOfRoll = result[]

Multiple of the same type of die:

using RPGHelper

result = roll(2d4)
sumOfRoll = result[]

Multiple different types of dice:

using RPGHelper

# Add the results
result = roll(d4 + d8)
sumOfRoll = result[]

# Subtract the results
result = roll(d8 - d4)
sumOfRoll = result[]

# Any Combination
result = roll(2d10 - d4 + d8)
sumOfRoll = result[]

Other simple operators: *, /, ^, %, abs, floor, ceil, abs

Add Integer Constants:

using RPGHelper

# Add a constant
result = roll(d4 + 2)
sumOfRoll = result[]

# Subtract a constant
result = roll(d10 - 3)
sumOfRoll = result[]

Each of the standard dice have been defined:

• d2
• d4
• d8
• d10
• d12
• d20
• d100
• dF

To create a die of any side count, N:

const weirdDie = RPGHelper.Die(15)

To create non-uniform dies:

const dNonUnifrom = NonUniformDie(1,2,2,3,3,0)

Modifiers

A standard set of roll modifiers are available. Modifiers only affect Single Dies or multiples of the Same Die Type

Explode:

# Explode on highest roll
results = 3d6 |> Explode() |> roll
sumOfRoll = results[]

# Explode on number
results = 3d8 |> Explode(5) |> roll

# Explode on condition
results = 3d10 |> Explode(x->3 <= x <= 5) |> roll

# Explode Chaining
results = 3d20 |> Explode(1) |> Explode(2) |> roll

# Explode Once
results = 3d4 |> Explode(once = true) |> roll

There are explode variants:

• Compounding: Explode(compounding = true)
• Penetrating: Explode(penetrating = true)

They variants can be combined

Reroll:

# Reroll on lowest roll
results = 3d6 |> Reroll() |> roll
sumOfRoll = results[]

# Reroll on number
results = 3d8 |> Reroll(5) |> roll

# Reroll on condition
results = 3d10 |> Reroll(x->3 <= x <= 5) |> roll

# Reroll Chaining
results = 3d20 |> Reroll(1) |> Reroll(2) |> roll

# Reroll Once
results = 3d4 |> Reroll(once = true) |> roll

Keep:

# Keep the 4 highest rolls
results = 8d6 |> Keep(4) |> roll
results = 8d6 |> Keep(:high, 4) |> roll

# Keep the 4 lowest rolls
results = 8d6 |> Keep(:low, 4) |> roll

Drop:

# Drop the 4 lowest rolls
results = 8d6 |> Drop(4) |> roll
results = 8d6 |> Drop(:low, 4) |> roll

# Drop the 4 highest rolls
results = 8d6 |> Drop(:high, 4) |> roll

Modifiers can be chained together. They follow the order of:

1. Explode, Penetrating, Compounding
2. Reroll
3. Keep
4. Drop
