如何在Unity 3D中播放多个声音
我正在使用Vuforia和Unity 4.6开发增强现实钢琴。该应用程序将是一个游戏，手机会说一个音符，例如：“C”，用户将有5秒钟在带有虚拟按钮的纸钢琴中弹奏音符。
我遇到的问题是，当我按下按钮时，我没有听到钢琴键的声音。我在switch语句中输入了所需的大小写，但没有播放声音。更新函数或OnButtonPressed（）上的play（）方法都在播放。但是关于方法generarNota（）。我总是听着电话里的声音说出来。
这是我的代码：

这也是我的编辑器截图，因此您可以检查我是否有附加到每个音频源的音频剪辑。
有谁能帮我找到问题所在？
1 个答案:
答案 0 :(得分：3)
创建一个数组，而不是多个AudioSource。 2关于代码结构的主要问题。
1 - 仅适用于使用可以使用多个分接头的移动设备。你没有使用Touches
2 - 因为你没有使用Array。您总是必须使用新的音频源删除当前正在播放的音频源，而不是从AudioSource阵列进行迭代。 audio.clip将始终删除正在播放的当前播放。
AudioSource[] myNotes;
myNotes[0].PlayOnce();
myNotes[3].PlayOnce();
//Don't do this.
// audio.clip = <---- NO!!!
