RCWeb Racer App

The RCWeb Racer App (app/racer) is a top-down multiplayer circuit racer built with the Asymmetric Pattern. A shared viewer renders a glowing figure-eight track while phones act as personal steering controls.

What it does

• Five-lap racing: Players race brightly colored cars around a large figure-eight circuit. The first car to finish five laps wins.
• Track-vs-grass handling: Cars accelerate hardest on the tarmac. Grass allows shortcuts in small doses, but it sharply reduces top speed and traction.
• Shortcut protection: If a driver skips a large section of the course, the game triggers an explosion, plays a warning effect, and rewinds that car to the point where it left the track.
• Attract mode: When nobody has joined yet, four demo cars loop around the course so the screen still feels alive and inviting.

How it works

• Sampled track math: script.js builds a procedural figure-eight centerline, measures cumulative lap distance, and projects each car to the nearest point on that path to handle ranking, lap progress, and off-track checks.
• Analog driving model: Cars use continuous speed, steering, acceleration, braking, drag, and surface grip values rather than tile steps, which makes the controller feel closer to a cartoon racing game than an arcade shooter.
• Asymmetric RCWeb messaging: The viewer listens for racer.remoteControl(...) calls from app/racer-control, then sends back player registration, lap, place, and status updates targeted at each phone.
