我正在 SDL 2 中制作一个有声音的俄罗斯方块版本。我有背景音乐,效果很好。但是,声音效果(移动、旋转等)播放的是静态的,而不是它们应该播放的。

一些代码:

定义:

Mix_Music *music;
Mix_Chunk *move, *rotate, *clear, *difficult, *gameOver;

开头:

if (Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, 4, 2048) != 0) {
    printf("Error: Failed to initiate Mixer subsystem. SDL_Mixer Error: %s\n", Mix_GetError());
    return false;
}

music = Mix_LoadMUS("music.wav");
if (music == NULL) {
    printf("Failed to load Music. SDL_Mixer Error: %s\n", Mix_GetError());
}

move = Mix_LoadWAV("move.wav");
if (move == NULL) {
    printf("Failed to load sound \"move\". SDL_Mixer Error: %s\n", Mix_GetError());
}

rotate = Mix_LoadWAV("rotate.wav");
if (rotate == NULL) {
    printf("Failed to load sound \"rotate\". SDL_Mixer Error: %s\n", Mix_GetError());
}
...
Mix_VolumeMusic((128 * options[0].currentOption * options[1].currentOption) / 10000); // (128 * 20 * 100) / 10000 = 25;
Mix_VolumeChunk(move, (128 * options[0].currentOption * options[2].currentOption) / 10000); // (128 * 20 * 100) / 10000 = 25;
Mix_VolumeChunk(rotate, (128 * options[0].currentOption * options[2].currentOption) / 10000); // (128 * 20 * 100) / 10000 = 25;
...

播放声音代码:

Mix_PlayChannel(-1, move, 0);

关:

Mix_FreeMusic(music);
music = NULL;
Mix_FreeChunk(move);
Mix_FreeChunk(rotate);
Mix_FreeChunk(clear);
Mix_FreeChunk(difficult);
Mix_FreeChunk(gameOver);
move = NULL;
rotate = NULL;
clear = NULL;
difficult = NULL;
gameOver = NULL;

Mix_Quit();

杂项信息:

  • 在 VS 2013 中使用 C++
  • 使用昨天下载的 SDL_mixer 2.0.0
  • 声音约为 11kB,音乐为 94,675kB
  • 声音在 Windows Media Player 中播放良好

如果您需要任何其他信息,请告诉我,并提前致谢!
