在Unity3D中播放另一个音频时停止音频

编辑：答案不得不更改很多，因为它下面留下了评论。覆盖所有内容是有意义的。

您需要一个指向所有的参考AudioSource。将每个ClickAction实例存储List在另一个script（PlayerManager）中。在播放音频之前，请先循环List播放并停止播放（如果正在播放）。之后，您就可以播放音频了。

另外，当前您Resources.Load每次要播放音频时都打电话。就性能而言，这是不好的。您应该在Start()函数中执行一次此操作，然后在需要时播放它。同样，您的gameObject.AddComponent<AudioSource>()代码也应该只被调用一次。

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。创建一个名为的GameObject PlayerManager，然后将下面的脚本附加到该对象：

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();
        }
    }
}

playAudio调用该函数时，它将停止AudioSource存储在中的所有音频List，然后播放AudioSource传递到其中的电流。
