game-audio

You are an expert game audio engineer. You use the Web Audio API for both background music (looping sequencer) and one-shot sound effects. Zero dependencies — everything is built into the browser.

How to use game-audio on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add game-audio

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/opusgamelabs/game-creator --skill game-audio

Fetches game-audio from opusgamelabs/game-creator and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/game-audio

Restart Cursor to activate game-audio. Access via /game-audio in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

✓

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

✓

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

File Structure

src/ ├── audio/ │ ├── AudioManager.js # AudioContext init, BGM sequencer, play/stop │ ├── AudioBridge.js # Wires EventBus → audio playback │ ├── music.js # BGM patterns (sequencer note arrays) │ └── sfx.js # SFX (one-shot oscillator + gain + filter)

AudioManager (BGM Sequencer + AudioContext)

The AudioManager owns the AudioContext (created on first user interaction for autoplay policy) and runs a simple step sequencer for BGM loops.

// AudioManager.js — Web Audio API BGM sequencer + SFX context class AudioManager { constructor() { this.ctx = null; this.currentBgm = null; // { stop() } this.masterGain = null; } init() { if (this.ctx) return; this.ctx = new (window.AudioContext || window.webkitAudioContext)(); this.masterGain = this.ctx.createGain(); this.masterGain.connect(this.ctx.destination); } getCtx() { if (!this.ctx) this.init(); return this.ctx; } getMaster() { if (!this.masterGain) this.init(); return this.masterGain; } playMusic(patternFn) { this.stopMusic(); try { this.currentBgm = patternFn(this.getCtx(), this.getMaster()); } catch (e) { console.warn('[Audio] BGM error:', e); } } stopMusic() { if (this.currentBgm) { try { this.currentBgm.stop(); } catch (_) {} this.currentBgm = null; } } setMuted(muted) { if (this.masterGain) { this.masterGain.gain.value = muted ? 0 : 1; } } } export const audioManager = new AudioManager();

AudioBridge (wiring EventBus -> audio)

import { eventBus, Events } from '../core/EventBus.js'; import { audioManager } from './AudioManager.js'; import { gameplayBGM, gameOverTheme } from './music.js'; import { scoreSfx, deathSfx, clickSfx } from './sfx.js'; export function initAudioBridge() { // Init AudioContext on first user interaction (browser autoplay policy) eventBus.on(Events.AUDIO_INIT, () => audioManager.init()); // BGM transitions eventBus.on(Events.MUSIC_GAMEPLAY, () => audioManager.playMusic(gameplayBGM)); eventBus.on(Events.MUSIC_GAMEOVER, () => audioManager.playMusic(gameOverTheme)); eventBus.on(Events.MUSIC_STOP, () => audioManager.stopMusic()); // SFX (one-shot) eventBus.on(Events.SCORE_CHANGED, () => scoreSfx()); eventBus.on(Events.PLAYER_DIED, () => deathSfx()); }

Integration Checklist

Create src/audio/AudioManager.js — AudioContext + sequencer + master gain

Create src/audio/music.js — BGM patterns as note arrays + sequencer calls

Create src/audio/sfx.js — SFX using Web Audio API (oscillator + gain + filter)

Create src/audio/AudioBridge.js — wire EventBus events to audio

Wire initAudioBridge() in main.js

Emit AUDIO_INIT on first user click (browser autoplay policy)

Emit MUSIC_GAMEPLAY, MUSIC_GAMEOVER, MUSIC_STOP at scene transitions

Add mute toggle — AUDIO_TOGGLE_MUTE event, UI button, M key shortcut

Test: BGM loops seamlessly, SFX fire once and stop, mute silences everything
