Engine-neutral\n  algorithms. Use when the user mentions procedural generation, perlin/simplex\n  noise, random seed, dungeon generator, heightmap/terrain, or loot tables.\n---\n\n# Procedural generation\n\nGenerate levels, terrain, and loot from compact rules and a seed. The throughline\nof good procgen is **determinism**: a single seed reproduces the same world, so\nbugs are repeatable and players can share seeds. This skill owns the core\nalgorithms — noise, seeded RNG, dungeon layout, weighted tables; genres like\n`roguelike` and `survival-crafting` consume it.\n\n## When to use\n\n- Use to generate maps, dungeons, terrain heightmaps, item drops, or any content\n  you do not want to author by hand.\n- Use when results must be **reproducible from a seed** (debugging, daily\n  challenges, shareable worlds).\n- Use to pick weighted random outcomes (loot rarity, spawn tables).\n\n**When *not* to use:** for the engine's tile API to *paint* the result, use\n`godot-tilemap` or `unity-tilemap-2d`. For routing AI through the generated map,\nuse `game-ai`. For carefully hand-paced levels, use `level-design` — procgen and\nauthored design are complementary, not interchangeable.\n\n## Core workflow\n\n1. **Own your randomness.** Create one seeded RNG instance and pass it\n   everywhere. Never call the global/static random in generation code — it makes\n   results irreproducible and order-dependent.\n2. **Pick the technique for the content.** Continuous terrain/heightmaps → noise.\n   Discrete rooms/corridors → space partitioning or agent-based carving.\n   Outcomes with rarities → weighted tables.\n3. **Generate into a plain data grid/array first**, decoupled from rendering.\n   Generation fills `int[][]` or a dict; a separate pass draws it.\n4. **Validate before shipping the result to the player.** Is every room\n   reachable? Is the spawn safe? Is there a path to the exit? Reject or repair\n   layouts that fail; do not hand the player a broken map.\n5. **Tune with the seed fixed** so each parameter change is visible in isolation,\n   then sweep seeds to check the distribution, not just one lucky map.\n\n## Patterns\n\n### 1. Seeded, deterministic RNG (the foundation)\n\n```python\nimport random\nrng = random.Random(seed)        # a dedicated instance — NOT the global random.*\nroom_count = rng.randint(5, 12)  # same seed -> same sequence, every run\n# RIGHT: thread `rng` through every function that makes a choice.\n# WRONG: calling random.randint(...) (global state) — order-dependent, unseedable.\n```\n\nEngine equivalents: Godot `var rng = RandomNumberGenerator.new(); rng.seed = s`;\nUnity `var rng = new System.Random(seed)` (or `UnityEngine.Random.InitState`).\nStore the seed in the save file so a world can be regenerated.\n\n### 2. Fractal (fBm) noise for heightmaps\n\n```python\n# Sum several octaves: each higher octave has higher frequency, lower amplitude.\ndef fbm(noise, x, y, octaves=5, lacunarity=2.0, gain=0.5):\n    total, amp, freq, norm = 0.0, 1.0, 1.0, 0.0\n    for _ in range(octaves):\n        total += amp * noise(x * freq, y * freq)   # noise() returns ~0..1\n        norm  += amp                                # track total amplitude\n        amp   *= gain                               # each octave contributes less\n        freq  *= lacunarity                         # ...at a higher frequency\n    return total / norm                             # normalize back into 0..1\n\n# Redistribute to carve flat valleys / sharpen peaks: higher exp -> more lowland.\nelevation = pow(fbm(noise, nx, ny), 2.2)\n```\n\nUse a real noise library (`FastNoiseLite`, `opensimplex`,\n`Unity.Mathematics.noise`, or `Mathf.PerlinNoise`) — do not implement gradient\nnoise yourself. Seed **elevation and moisture with different seeds** so a\nbiome lookup over both fields isn't perfectly correlated. Full biome lookup and\nisland shaping are in `references/noise.md`.\n\n### 3. Weighted loot table (rarity-correct selection)\n\n```python\n# Roll proportional to weight: common drops far more often than legendary.\ndef weighted_pick(rng, table):           # table: list of (item, weight)\n    total = sum(w for _, w in table)\n    roll = rng.uniform(0, total)          # a point on the cumulative line\n    upto = 0.0\n    for item, w in table:\n        upto += w\n        if roll < upto:                   # first bucket the roll falls into\n            return item\n    return table[-1][0]                   # float-safety fallback\n\nloot = weighted_pick(rng, [(\"common\", 70), (\"rare\", 25), (\"legendary\", 5)])\n```\n\nWeights need not sum to 100 — they are relative. To prevent bad streaks, use a\n\"pity\"/bag system (see `references/dungeon-generation.md` notes on distributions).\n\n### 4. Rooms-and-corridors dungeon (sketch)\n\n```python\n# 1. Place non-overlapping rooms; 2. connect them; 3. carve into the grid.\nrooms = []\nfor _ in range(attempts):\n    r = Rect(rng.randint(1, W-w-1), rng.randint(1, H-h-1), w, h)\n    if not any(r.intersects(o.expand(1)) for o in rooms):  # keep a 1-tile gap\n        rooms.append(r)\nfor a, b in zip(rooms, rooms[1:]):       # connect each room to the next\n    carve_l_corridor(grid, a.center, b.center, rng)   # horizontal then vertical\n```\n\nThe complete generator (BSP partitioning, L-corridors, reachability check, and\nrandom-walk caves) is in `references/dungeon-generation.md`.\n\n## Pitfalls\n\n- **Using the global RNG** inside generation makes worlds unreproducible and\n  breaks the moment call order changes. Always pass a seeded instance.\n- **Correlated noise fields**: sampling elevation and moisture from the *same*\n  seed/offset produces biomes that line up in bands. Offset or reseed each field.\n- **Octave artifacts**: adding octaves without renormalizing pushes values out of\n  `0..1`; divide by the summed amplitude (and beware library output ranges — some\n  return `-1..1`, some `0..1`).\n- **No connectivity check**: rooms or caves can end up isolated. Flood-fill from\n  the spawn and discard/reconnect unreachable regions before play.\n- **Unbounded placement loops**: \"keep trying until N rooms fit\" can spin forever\n  on a small grid. Cap attempts and accept fewer rooms.\n- **Seeding once globally, then relying on frame timing**: any non-deterministic\n  input (time, physics, hash randomization) leaking into generation destroys\n  reproducibility.\n\n## References\n\n- `references/noise.md` — octaves/lacunarity/gain, redistribution, island\n  shaping, two-axis biome lookup, blue-noise object scatter.\n- `references/dungeon-generation.md` — BSP, rooms+corridors, random-walk caves,\n  cellular-automata smoothing, connectivity validation, distribution/pity tables.\n\n## Related skills\n\n- `godot-tilemap`, `unity-tilemap-2d` — paint the generated grid into the engine.\n- `game-ai` — pathfinding over the generated graph.\n- `level-design` — pacing and hand-authored structure that procgen complements.\n- `roguelike`, `survival-crafting` — genres that compose this skill.\n","tagline":"Generate game content procedurally — seeded deterministic RNG, value/Perlin/ Simplex noise for terrain and heightmaps, grid dungeon generation (rooms + corridors, BSP, random walk), and weighted loot/drop tables.
