game-audio

Purpose

This skill enables real-time audio processing in game engines, managing sound effects, music playback, and spatial audio for immersive experiences. It integrates with engines like Unity or Unreal to handle audio streams, effects, and positioning, ensuring low-latency performance in games.

When to Use

• Developing games that require dynamic audio, such as responsive sound effects for player actions.

• Implementing spatial audio for VR/AR games to simulate 3D sound environments.

• Optimizing audio for performance in resource-constrained mobile games.

• When you need to mix audio layers, like background music with in-game effects, using engine-specific APIs.

Key Capabilities

• Process real-time audio streams with effects like reverb, echo, and pitch shifting via the processAudio function.

• Handle spatial audio using vector-based positioning, e.g., calculating sound attenuation based on player coordinates.

• Support multiple audio formats (WAV, MP3, OGG) and dynamic volume control.

• Integrate with game loops for event-driven audio triggers, such as playing a sound on collision detection.

• Provide audio analysis tools, like frequency spectrum detection for adaptive music.

Usage Patterns

To use this skill, first initialize it in your game engine script, then call methods for audio playback or processing. Always check for audio context availability before operations. For CLI usage, run commands from the project root directory. Pattern: Import the skill, set up authentication with $GAME_AUDIO_API_KEY , and use event handlers for audio events.

Common Commands/API

• CLI Command: claw audio play --file assets/sound.wav --volume 0.8 --loop true

• Flags: --file specifies the audio file path; --volume sets level (0.0-1.0); --loop enables looping.

• API Endpoint: POST /api/game-audio/play with JSON body: {"file": "assets/sound.wav", "position": [0, 0, 0]}

• Requires header: Authorization: Bearer $GAME_AUDIO_API_KEY

• Code Snippet (Python): import claw_audio claw_audio.init(key=os.environ['GAME_AUDIO_API_KEY']) claw_audio.play_sound('assets/sound.wav', volume=0.5)

• Code Snippet (C# for Unity): using ClawAudio; void Start() { AudioManager.Instance.Play("assets/music.mp3", loop: true); }

• Config Format: JSON for audio settings, e.g., {"effects": {"reverb": 0.3}, "spatial": true} . Load via claw_audio.load_config('config.json') .

Integration Notes

Integrate by adding the skill as a dependency in your project (e.g., via npm for Node.js or Unity package manager). Ensure audio hardware is detected using claw_audio.check_device() . For cross-engine compatibility, wrap calls in abstraction layers. If using with other OpenClaw skills, pass audio events via the cluster (e.g., link to "game-dev" skills). Set env var for auth: export GAME_AUDIO_API_KEY=your_key. Test integration in a sandbox environment before production.

Error Handling

Always wrap audio calls in try-catch blocks to handle exceptions like file not found or API failures. Common errors: "Audio device unavailable" – check with claw_audio.is_device_ready() and retry after 2 seconds. For API errors, verify status codes (e.g., 401 for unauthorized) and log with claw_audio.log_error(message) . Use custom handlers: e.g., in code:

try: claw_audio.play_sound('file.wav') except AudioError as e: print(f"Error: {e}. Retrying...") claw_audio.retry_operation()

Monitor for latency issues by setting timeouts on commands, e.g., --timeout 5000 in CLI.

Concrete Usage Examples

Playing a sound effect on player jump in a Unity game:

• Code: void OnJump() { AudioManager.Instance.Play("jump.wav", position: playerTransform.position); }

• Steps: Initialize AudioManager in Start(), ensure $GAME_AUDIO_API_KEY is set, and call OnJump() on input event.

Implementing spatial audio for enemy detection in a 3D game:

• Code: def detect_enemy(): position = [enemy_x, enemy_y, enemy_z] claw_audio.play_spatial('alert.mp3', position=position, radius=5.0)

• Steps: Call detect_enemy() in the game loop, pass player position for attenuation, and adjust radius for sound fade.

Graph Relationships

• Related to: "game-dev" cluster (e.g., skills like game-rendering for synchronized audio-visual effects).

• Connected via tags: "audio" links to skills like speech-recognition; "sound" to audio-editing tools.

• Dependencies: Requires "core-audio" for base functionality; integrates with "game-physics" for spatial calculations.
