DRIVING SIMULATOR

Controls

Action	Key	Range
Throttle Up	=	0 – 10
Throttle Down	-	0 – 10
Brake Up	A	0 – 5
Brake Down	Z	0 – 5
Steer Left	←	-10 to 10
Steer Right	→	-10 to 10
Restart	R	—

All controls are tap-to-set — each press adjusts the value by 1 step. Steering stays at the set angle until changed.

Scoring

• +10 Pass through a gate (between consecutive cones)
• -10 Hit a cone (also voids the next gate)
• FAIL Drive off the road

Weave between the centre-line cones to collect gates and maximise your score. Reach the chequered finish line to complete the course.

Vehicle Configuration

Power

Affects acceleration rate — higher power reaches target speed faster

Weight

Affects braking performance — heavier vehicles carry more momentum and brake slower

Turning Circle

Affects steering responsiveness — higher values give tighter, more responsive turns

Default configuration: Power 5, Weight 5, Turning Circle 5. The throttle sets a target speed (each level = 15 px/s), and the vehicle accelerates toward it based on power.

The Engine

Built on pb-galaga engine patterns — decoupled game logic and rendering for clean architecture and headless testing.

Language

TypeScript (strict mode)

Rendering

Canvas 2D — no framework

Audio

Procedural synthesis (Web Audio API)

Physics

60 Hz fixed timestep with interpolation

Build

15 KB single-file — zero runtime dependencies

Testing

75 unit tests (Vitest, headless)
