API & Schema Reference

The reference is auto-generated from the engine’s own definitions, so it always matches the code:

• Engine API — phase ordering and the GameComponent contract (from engine-api.json).
• Scene Schema — the full .vscn.json format (from the Zod schemas via generate-schema).
• Prefab Schema — the full .prefab.json format.

Engine API Phases + GameComponent lifecycle

Scene Schema Every .vscn.json field, described

Prefab Schema Every .prefab.json field, described

Single source of truth

Schemas live in packages/engine/src/scene/schema/ as Zod objects. Every field has a .describe() call; those descriptions power this reference, JSON-Schema autocomplete in VS Code, and the editor inspector.
