• Draw2D, Assets, Audio, Storage, and Math Exact Reference

Fast Routing

Namespace Map

• lifecycle: aura.setup, aura.update(dt), aura.draw, aura.onResize, aura.onFocus, aura.onBlur, aura.onQuit
• runtime shell: aura.window, aura.input
• 2D render path: aura.draw2d, 2D camera helpers
• content and persistence: aura.assets, aura.audio, aura.storage, aura.fs
• primitives and values: aura.rgb, aura.rgba, aura.Color, aura.vec2, aura.vec3

Exact Reading Order

1. Use the matching handbook section above.
2. If you already know the subsystem, move to one of the narrower split routes above.
3. Confirm the exact method or option shape in ../api-contract.md.

Practical Rule

If the work is in a normal first game loop, start here before opening the full contract from the top. This family covers most early AuraJS work.
