Question

我无法通过单击一次按钮来找出播放和暂停音频源的正确代码。

这是我的代码

ButtonAction.GetComponent().onClick.AddListener(delegate
                     {
                         if (soundTarget.isPlaying)
                         {
                             soundTarget.Pause();
                         }
                         else if(!soundTarget.isPlaying)
                         {
                             soundTarget.Play();
                             playSound("sounds/English");
                         }
                     });

注意：默认情况下它不会播放，因为如果我默认情况下播放，它只会循环播放。它可以正常工作，但我需要多次单击按钮才能播放或暂停。

救救我。

这很简单：

您的Unity场景应该是这样的：

对于我称为“ UnityUI”的脚本，如下所示：

public AudioSource MyAudioSource;
public Button PlayBtn;
public PlayButtonText;

void Start()
{
    PlayBtn.onClick.AddListener(() =>
    {
        if (MyAudioSource.isPlaying)
        {
            MyAudioSource.Stop();
            PlayButtonText.text = "Play me!";
        }
        else
        {
            MyAudioSource.Play();
            PlayButtonText.text = "Stop me!";
        }
    });
}

希望这对您有所帮助！

编码愉快！

Answer 2

我的代码应该是这样的。单击该按钮时，它将播放声音，再次单击时，它将暂停。

void Update()
    {
            StateManager sm = TrackerManager.Instance.GetStateManager();
            IEnumerable<TrackableBehaviour> tbs = sm.GetActiveTrackableBehaviours();

            foreach (TrackableBehaviour tb in tbs)
            {
                string name = tb.TrackableName;
                ImageTarget it = tb.Trackable as ImageTarget;
                Vector2 size = it.GetSize();

                Debug.Log("Active image target:" + name + "  -size: " + size.x + ", " 
                + size.y);

                ButtonAction.gameObject.SetActive(true);
                TextDescription.gameObject.SetActive(true);
                PanelDescription.gameObject.SetActive(true);
                ButtonMute.gameObject.SetActive(true);

                if (name == "quezon")
                {
                    ButtonAction.GetComponent<Button>().onClick.AddListener(delegate
                    {
                        if (soundTarget.isPlaying)
                        {
                            soundTarget.Pause();
                            btn.image.overrideSprite = Play;
                        }
                        else
                        {
                            btn.image.overrideSprite = Pause;
                            playSound("sounds/English");
                            soundTarget.Play();
                        }
                    });

                TextDescription.GetComponent<Text>().text = "Manuel L. Quezon was 
                born on August 19, 1878, and died on August 1, 1944. He was a 
                Filipino statesman, soldier, and politician who served as president 
                of the Commonwealth of the Philippines from 1935 to 1944.";
                Narrator.gameObject.SetActive(true);

                void playSound(string ss)
                     {
                       clipTarget = (AudioClip)Resources.Load(ss);
                       soundTarget.clip = clipTarget;
                       soundTarget.loop = false;
                       soundTarget.playOnAwake = false;     
                       soundTarget.ignoreListenerPause = true;
                     }

Unity播放暂停音频效果不佳
