Oestus TTRPG Random Number Generator

Developed for UltraSkull1000/Malaco-5 as a universal ttrpg dice solution. Written in C# with .NET 8.0.

Screenshot of a Discord Bot User, named Malaco, responding to a slash command, /roll, run by a user nickanamed Mac. The bot responded with @Mac rolled d20+6 for a total of 8! with a breakdown of how that result was achieved.

Usage

Oestus Provides a number of ways to roll TTRPG Dice, for both backend and frontend uses.

To roll dice in the backend, you can use the method Oestus.Dice.RollDice(int faces) to roll one die of the specified size, or its overload, Oestus.Dice.RollDice(int faces, int count, out List<int> result) to roll many dice, with the return providing a sum and the output list providing the individual dice.

Similarly, rolling fudge dice is done with the method Oestus.Dice.RollFudgeDice() for one die, and Oestus.Dice.RollFudgeDice(int count, out List<int> result) for multiple.

You can use the result lists with the helper methods, such as Oestus.Dice.Drop() to modify their results. Additionally, for a user-readable view of the dice, you can use List<int>().ToDiceString() as provided by Oestus.Dice to produce a formatted list.

For user-interactible dice rolling, it is recommended to use the OestusRNG.Dice.Parse(string query, out string resultString) to parse dice strings in the following format:

Format Description Example Sample Result
d(f) Rolls one die with (f) faces. d20 6 (1d20 = 6)
(c)d(f) Rolls (c) dice with (f) faces. 3d8 15 (3d8 = 15 {(2) + (6) + (7)})
(c)dF Rolls (c) fudge dice. 6dF 0 (6dF = 0 {(1) + (-1) + (0) + (1) + (0) + (-1)})
(roll) + (i) Rolls a die/dice, then adds (i) to the result. d20+6 8 (1d20 = 2) + 6
(roll)a Rolls a die with Advantage. d20a 11 (1d20a = 11 ̶2)
(roll)s Rolls a die with Disadvantage d20s 5 (1d20s = 5 ̶18)
(roll)dl(mn) Rolls dice, then drops the lowest (mn) results. 4d6dl1 12 (4d6dl1 = 12 {(6), (5), (1), (̶1)})
(roll)dh(mx) Rolls dice, then drops the highest (mx) results. 4d6dl1 10 (6d8dh2 = 10 {(1), (3), (3), (3), (̶6), (̶8)})
(roll)dm(mn) Rolls dice, then replaces any results below (mn) with (mn). d20dm10 10 (1d20dm10 = (̶3 10))
(roll)dx(mx) Rolls dice, then replaces any results above (mx) with (mx). 3d8dx6 15 (3d8dx6 = 15 {((̶7 6), 3, (̶8 6))})
(roll) + (roll) Any number of rolls can be added together. d20 + 1d4 6 (1d20 = 2) + (1d4 = 4)
(c)d(f1)d(f2) Trivial Nesting. For when you want to use shorthand for nesting. 1d4d12 23 (3d12 = 23 {(12) + (1) + (10)})
(subquery)d20 Queries can be nested using parenthesis, queries within parenthesis will be calculated first.[^1] (3d6+2)d20 161 ((3d6 = 11 {(2) + (3) + (6)}) + 2) (13d20 = 161 {(4) ...

[^1]: Subqueries can also be nested within. It is recommended not to go more than 8 levels deep, but it should be fine.
