Procedural generation

Generate levels, terrain, and loot from compact rules and a seed. The throughline of good procgen is determinism: a single seed reproduces the same world, so bugs are repeatable and players can share seeds. This skill owns the core algorithms — noise, seeded RNG, dungeon layout, weighted tables; genres like roguelike and survival-crafting consume it.

When to use

• Use to generate maps, dungeons, terrain heightmaps, item drops, or any content you do not want to author by hand.
• Use when results must be reproducible from a seed (debugging, daily challenges, shareable worlds).
• Use to pick weighted random outcomes (loot rarity, spawn tables).

When not to use: for the engine's tile API to paint the result, use godot-tilemap or unity-tilemap-2d. For routing AI through the generated map, use game-ai. For carefully hand-paced levels, use level-design — procgen and authored design are complementary, not interchangeable.
