如何在 Unity 3D 中播放多个声音

Question

我正在使用 Vuforia 和 Unity 4.6 开发增强现实钢琴。该应用程序将是一款游戏，其中手机 phone 会说出一个音符，例如："C"，用户将有 5 秒的时间在带有虚拟按钮的纸钢琴上弹奏该音符。

我遇到的问题是按下按钮时听不到钢琴键的声音。我确实在 switch 语句中输入了所需的情况，但是没有声音是 played.Neither Update 函数或 OnButtonPressed() 上的 play() 方法正在播放。但是在方法 generarNota() 上。我总是听 phone 说音符的声音。

这是我的代码：

public class ButtonControl : MonoBehaviour,IVirtualButtonEventHandler {
    public AudioSource c;
    public AudioSource cSharp;
    public AudioSource d;
    public AudioSource dSharp;
    public AudioSource e;

    public AudioSource c2;
    public bool gameOn;
    string currentNote; //Nota genereada por el sistema
    string inputNote; //Nota presionada por el usuario
    public float waitTime; //Tiempo de espera entre notas
    public float resetWait; // Para reiniciar el tiempo de espera
    public int totalNotes;
    public int correctNotes;
    public int incorrectNotes;
    bool firstNote;
    bool beingHandled;
    public bool blackNotes;
    bool notePressed;
    //Use this for initialization
    void Start () {
        c.PlayOneShot(c.clip);
        blackNotes = false;
        this.notePressed = false;
        beingHandled = false;
        currentNote="NONE";
        waitTime = 0;
        firstNote = true;
        VirtualButtonBehaviour[] vbs = GetComponentsInChildren<VirtualButtonBehaviour>();
        for (int i = 0; i < vbs.Length; ++i) {
            // Register with the virtual buttons TrackableBehaviour
            vbs[i].RegisterEventHandler(this);
        }

    }
    void generarNota(){
        if (blackNotes) {
                        int num = Random.Range (1, 13);

        }
    }
        //If para cada tecla del piano

        //audio.PlayOneShot(myClip);

        //Comparamos si las notas son iguales.
        //Si son iguales, sonido correcto+generar una nueva nota+sumar contador de puntos


        //Si no son iguales--> sonido de error+ terminar juego




    public void OnButtonReleased(VirtualButtonAbstractBehaviour vb){
        notePressed = false;
        this.inputNote = "NONE.";
        Debug.Log ("BUTTON UNPRESSED");



    }
}

这也是我的编辑器屏幕截图，因此您可以检查我是否为每个音频源附加了音频剪辑。

谁能帮我找出问题所在？

Answer 1

制作一个数组，而不是多个AudioSource。 2 关于代码结构的主要问题。

1 - 仅适用于可多次点击的移动设备。您没有使用 Touches

2 - 因为您没有使用数组。您总是必须用新的 Audio Source 移除当前播放的 Audio Source，而不是从 AudioSource Array 迭代。 audio.clip 将始终删除当前正在播放的那个。

AudioSource[] myNotes;
myNotes[0].PlayOnce();
myNotes[3].PlayOnce();

//Don't do this. 
// audio.clip = <---- NO!!!
