About Dice Roller Pro - Dice Notation Parser, Exploding Dice & Roll History for RPGs
KEY FEATURES
Comprehensive Dice Notation Parser - Standard NdX, percentile (d% / d100), Fate/Fudge (dF), custom faces (d[2,4,6,8]), and full mathematical expressions: + - * / %, parentheses, unary minus, and grouping {...}.
Every Modifier You Need
- Keep / Drop - kh, kl, dh, dl (D&D 5e ability scores, advantage, disadvantage)
- Exploding - ! basic, !! compound, !p penetrating
- Reroll - r recursive, ro once, rr reroll-and-keep (Great Weapon Fighting)
- Min / Max Clamp - mi, ma ("treat damage of less than 2 as 2")
- Critical / Fumble - cs, cf with full comparator support (cs>=19cf=1)
- Success Counting - 5d10>=8 for Storyteller / WoD / dice pools, with f botch subtraction
- Display Sort - s / sa / sd (cosmetic, totals unchanged)
- Math Functions - min, max, abs, floor, ceil, round for advantage rolls and capped damage
Three Editor Windows
- Expression Builder - form-style composer with a dice-kind picker, full modifier coverage in collapsible sections, live canonical-notation preview, Test Roll, and Save as Asset. No more memorising kh3 vs dl1.
- Expression Validator - instant parser feedback with severity-graded warnings.
- Probability Analyzer - Monte Carlo simulator (1k - 1M iterations, seedable) with mean / stddev / 95 % CI / ASCII histogram and a side-by-side two-expression compare mode.
ScriptableObject-First Workflow - Every dice type is a Unity asset. Drag into Inspector slots, share across prefabs, version-control as text. Custom inspectors with reorderable lists for groups and sequences, an inline Roll Preview (seed + histogram) on every dice asset, and per-type asset icons.
Pluggable RNG - Cross-platform deterministic RNG, snapshot / restore for save-games, and record / replay for bug repros and regression tests. Critical for multiplayer authoritative rolls and competitive game determinism.
Async + Bulk Rolling - Run any roll on the thread pool. Roll millions of iterations into a stats snapshot (count / min / max / mean / histogram) without stalling the main thread. Provides blazing fast running statistics.
Validation Framework - Catch invalid expressions, conflicting modifiers, and performance pitfalls before runtime. Severity-graded (Critical / Error / Warning / Info), category-tagged, with inline suggestions. Safe for user-generated content and modding scenarios.
Programmatic API - Static and fluent ModifiersBuilder for typed, validating, frozen-on-Build configuration. One-line API for game code; full extensibility when you need it.
Performance-First - Span-based parsing (zero-allocation hot paths), expression cache (auto-prewarmed), per-thread RNG. Designed for thousands of rolls per frame.
PERFECT FOR
- Tabletop RPG implementations - D&D 5e, Pathfinder, Call of Cthulhu, Storyteller / WoD, Fate, custom systems
- Board & strategy games - advantage rolls, dice pools, weighted outcomes
- Roguelikes & procedural generators - exploding loot tables, weighted custom dice, deterministic seeded runs
- Multiplayer & competitive games - authoritative rolls with snapshot / restore RNG
- Game prototypes & jams - go from "I need a dice roll" to working code in one line
- Tools and editors - modders and designers compose expressions visually instead of editing code
Stop reinventing the dice wheel. Drop in Dice Roller Pro and ship the dice mechanics your game deserves - validated, performant, and easy to author.
