c# - 在Unity3D中播放另一个音频时停止音频

Question

播放另一音频时如何停止音频？

public AudioSource audioSource;
public AudioClip audioClip;
private string[,] levelWords;
//public static string glupiaZmienna;
public Text txt;

public void OnPointerClick(PointerEventData eventData)
{
    Debug.Log(gameObject.name);
    WordsLoader w = new WordsLoader();
    levelWords = w.wLevelWords;
    SetCategoryButton scb = new SetCategoryButton();
    int a = scb.Kategoria;
    zupa();

    AudioSource audio = gameObject.AddComponent<AudioSource>();
    audio.Stop();
    audio.clip = (AudioClip)Resources.Load(a+ "/" + WordsLoader.language + "/Sounds/" + gameObject.name);

    audio.Play();


   // txt = gameObject.GetComponent<Text>();
}

public void zupa()
{ WordsLoader w = new WordsLoader();
    SetCategoryButton scb = new SetCategoryButton();
    int a = scb.Kategoria;
    print(w.wHowManyWords);

    for (int i = 0; i < w.wHowManyWords; i++)
    {
        print("jestem tu");
        if (levelWords[i, 0] == gameObject.name)
        {
            txt = GameObject.Find("Text").GetComponent<Text>(); ;
            txt.text = levelWords[i, 2];
        }

    }
}

此代码位于脚本中，单击按钮后便开始播放声音。我想停止较早开始的音频。

编辑:答案必须更改，因为其下方留有注释。覆盖所有内容是有意义的。

您需要一个指向所有AudioSource的引用。将每个ClickAction实例存储在另一个脚本(List)中的PlayerManager中。在播放音频之前，请遍历该List并停止播放(如果正在播放)。之后，您就可以播放音频了。

另外，您当前每次想播放音频时都调用Resources.Load。就性能而言，这是不好的。您应该在Start()函数中执行一次，然后在需要时播放。另外，您的gameObject.AddComponent<AudioSource>()代码也应该只调用一次。

您的新ClickAction脚本:

public class ClickAction : MonoBehaviour
{
    public AudioSource audioSource;
    public AudioClip audioClip;
    private string[,] levelWords;
    //public static string glupiaZmienna;
    public Text txt;

    public AudioSource clickAudioSource;
    PlayerManager playerManager = null;

    void Start()
    {
        //Get PlayerManager from PlayerManager GameObject
        playerManager = GameObject.Find("PlayerManager").GetComponent<PlayerManager>();
        clickAudioSource = gameObject.AddComponent<AudioSource>();
        clickAudioSource.clip = (AudioClip)Resources.Load(a + "/" + WordsLoader.language + "/Sounds/" + gameObject.name);

        //Register this Script to the PlayerManager 
        playerManager.addClickAction(this);
    }

    public void OnPointerClick(PointerEventData eventData)
    {
        Debug.Log(gameObject.name);
        WordsLoader w = new WordsLoader();
        levelWords = w.wLevelWords;
        SetCategoryButton scb = new SetCategoryButton();
        int a = scb.Kategoria;
        zupa();

        //Play Audio
        playAudio();

        // txt = gameObject.GetComponent<Text>();
    }

    private void playAudio()
    {
        playerManager.playAudio(clickAudioSource);
    }

    public void stopAudio()
    {
        //If not null and playing then stop audio
        if (clickAudioSource != null && clickAudioSource.isPlaying)
        {
            clickAudioSource.Stop();
        }
    }

    public void zupa()
    {
        WordsLoader w = new WordsLoader();
        SetCategoryButton scb = new SetCategoryButton();
        int a = scb.Kategoria;
        print(w.wHowManyWords);

        for (int i = 0; i < w.wHowManyWords; i++)
        {
            print("jestem tu");
            if (levelWords[i, 0] == gameObject.name)
            {
                txt = GameObject.Find("Text").GetComponent<Text>(); ;
                txt.text = levelWords[i, 2];
            }

        }
    }

    void OnDisable()
    {
        //Un-Register this Script from the PlayerManager when it is destroyed
        playerManager.removeClickAction(this);
    }
}

PlayerManager脚本。创建一个名为 PlayerManager的GameObject，然后将以下脚本附加到它:

public class PlayerManager : MonoBehaviour
{
    List<ClickAction> clickActions = new List<ClickAction>();

    public void addClickAction(ClickAction clickActionToAdd)
    {
        //Adds clickActionToAdd if it does not exist in the List already
        if (!clickActions.Contains(clickActionToAdd))
        {
            clickActions.Add(clickActionToAdd);
        }
    }

    public void removeClickAction(ClickAction clickActionToAdd)
    {
        //Removes clickActionToAdd if it exist in the List 
        if (clickActions.Contains(clickActionToAdd))
        {
            clickActions.Add(clickActionToAdd);
        }
    }

    public bool clickActionExist(ClickAction clickActionToAdd)
    {
        //Removes clickActionToAdd if it exist in the List 
        return clickActions.Contains(clickActionToAdd);
    }

    public void playAudio(AudioSource audSource)
    {
        //Stop Other Audio
        stopAllClickActionAudio();

        //Now, play the one that was passed in
        audSource.Play();
    }

    void stopAllClickActionAudio()
    {
        //Stop Audio on every ClickAction script
        for (int i = 0; i < clickActions.Count; i++)
        {
            clickActions[i].stopAudio();
        }
    }
}

调用 playAudio函数时，它将停止 AudioSource中存储的 List中的所有音频，然后它将播放传递到其中的当前 AudioSource。
