Knowra Procedural generation Procedural generation Procedural generation creates game content through algorithms rather than manually specifying every instance. It can produce terrain, levels, objects, narratives, or other content at runtime or during development.
Pseudorandom number generator : A deterministic algorithm that produces a sequence of numbers with statistical properties resembling randomness. Seeds let a game reproduce generated content while varying it across runs.
Procedural terrain generation : The algorithmic creation of landforms, elevation, and terrain features. Terrain is a prominent use of generated noise, rules, and spatial constraints.
Level design : The design of playable spaces, including their layout, pacing, and challenges. Hand-authored levels offer deliberate control over sequence and player experience.
Replay value : The capacity of a game to remain engaging across repeated playthroughs. Variation can make successive runs feel different, though not necessarily meaningful.
Perlin noise : A gradient-noise algorithm that creates smoothly varying values across space. Its continuous variation helps generate natural-looking terrain and textures.
Procedural level generation : The algorithmic creation of playable spaces, layouts, or sequences of challenges. Levels can be assembled to offer variation beyond hand-authored layouts.
Randomness : The absence of a predictable outcome under a specified model or process. Procedural generation may use randomness, but rules constrain its results.
Game balance : The design of fair and coherent relationships among a game's challenges, abilities, and resources. Generated combinations must remain playable and avoid unfair difficulty spikes.
Cellular automaton : A grid-based system whose cells change state according to local rules. Repeated local updates can turn random maps into cave-like spaces.
Procedural animation : Animation produced by rules or computation rather than solely by authored keyframes. Games use runtime rules to make motion respond to changing situations.
