我在SDL 2中制作了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)会播放静态而不是它们应该播放的声音。
一些代码:
说明:
Mix_Music *music;
Mix_Chunk *move, *rotate, *clear, *difficult, *gameOver;
一开始:
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);
关闭:
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();
