Architecture

AudioManager

Gère la musique de fond et les effets sonores.

class AudioManager {
    std::map<std::string, Sound> sounds_;
    Music* currentMusic_ = nullptr;
    float masterVolume_ = 0.8f;
    float musicVolume_ = 0.6f;
    float sfxVolume_ = 1.0f;

public:
    void loadSound(const std::string& name, const std::string& path);
    void playSound(const std::string& name);
    void playMusic(const std::string& path, bool loop = true);
    void stopMusic();

    void setMasterVolume(float vol);
    void setMusicVolume(float vol);
    void setSfxVolume(float vol);
};

VoiceChatManager

Gère la capture, l'encodage Opus et la transmission UDP.

class VoiceChatManager {
    OpusEncoder* encoder_;
    OpusDecoder* decoder_;
    PaStream* inputStream_;
    PaStream* outputStream_;
    UDPSocket& socket_;

public:
    void startCapture();
    void stopCapture();
    void processIncoming(const VoicePacket& packet);
    void setMode(VoiceMode mode);  // PTT or VAD
    void setMuted(bool muted);
};
