RCWeb Spacewar 3D Control App

The RCWeb Spacewar 3D Control App (app/spacewar3d-control) is the dedicated smart-controller for the 3D arcade shooter. It operates within the Asymmetric Pattern, delivering physical button feedback and synchronized native audio synthesis.

What it does

• Classic Arcade Interface: Retains the reliable, latency-free three-button layout (Left, Right, Fire) utilized in previous Spacewar iterations to maintain precision steering over the 3D ships on the main screen.
• Audio Duplication: Synthesizes and plays complex mathematical waveforms (like laser blasts and descending minor piano chord explosions) directly out of the phone's speaker in real-time correlation with the 3D action viewed on the primary display.
• Bi-directional Scores: Passively listens for WebSocket updates indicating user score bumps or deaths and visually updates its internal LCD-style score tracker interface.

How it works

The engine relies heavily on syncing browser physics and handling strict mobile browser policy workarounds.

• Audio Context Priming: Since Apple Safari and Google Chrome rigidly block all synthetic audio creation unless triggered immediately by a user input, it establishes an invisible initAudio listener attached exclusively to the first touchstart event on the entire document via { once: true }. This guarantees the AudioContext is unlocked well before the user attempts to furiously fire their laser.
• Mathematical Sound Design: The playSound('explosion') function doesn't play a file, it chains multiple audioCtx.createOscillator() instances set to triangle wave frequencies. It staggers their execution times (t, t+0.2, t+0.4) and modulates their gain using exponentialRampToValueAtTime to build a complex, multi-layered sad notification chord perfectly inside native Javascript.
