Audio

Sound system: channels, assets, and playback.

Overview

Audio is handled by the SoundManager class (src/GalaxyEggbert/Game/SoundManager.hpp/.cpp). It wraps the Urho3D audio subsystem and provides 93 named sound channels matching the original game's sound table.

Sound Assets

93 WAV files are stored in Content/sounds/: sound000.wav … sound092.wav. The file indices map directly to SoundChannel enum values. These are the same WAV files as the original Speedy Blupi game.

SoundChannel Enum

Defined in include/GalaxyEggbert/def/SoundChannel.hpp. Values range from SoundChannel0 (reserved) to SoundChannel92. Do not renumber — indices must match the original game's sound table.

Wired Sound Events

Playback Behavior

• Same-channel conflict policy: a playing channel is not restarted, except SoundChannel10 (treasure pickup).
• Volume per channel is taken from the tableVolumePitch table ported from mobile-eggbert. Needs verification: exact volume values are in SoundManager.cpp.
• When sound is disabled (SoundManager::SetEnabled(false)), Play() is a no-op and all channels are stopped.
• Sound can be toggled from the settings screen (S key) and is persisted in the save file.

API

class SoundManager {
    void Play(SoundChannel channel, bool loop = false);
    void Stop(SoundChannel channel);
    void StopAll();
    void SetEnabled(bool enabled);
    bool IsEnabled() const;
};

Urho3D Integration

Each channel corresponds to a Urho3D::Sound resource and a Urho3D::SoundSource component on an audio node in the scene. The SoundManager creates all 93 channels at construction by loading resources from the cache.

Web / Browser Audio

Browsers require a user gesture before audio starts. If no sound is heard in the Web build, click the canvas once. This is a browser security policy, not a bug in Galaxy Eggbert.
