继续在不同场景中播放音频 [英] Continues to play audio in different scenes

问题描述

在我的Unity项目中，有不同的菜单，并且每个菜单都是不同的场景.每个场景都有用于控制音乐的按钮.

In my Unity Project, there are different menus, and each menu is a different scene. Each scene has button for controlling the music.

public void musicToggle(GameObject Off){
        if (PlayerPrefs.GetInt ("Music") == 1) {
            musicPlayer.Stop ();
            Debug.Log ("Stop 2");
            PlayerPrefs.SetInt ("Music", 0);
            Off.SetActive(true);
        }
        else {
            musicPlayer.Play ();
            Debug.Log ("Play 2");
            PlayerPrefs.SetInt ("Music", 1);
            Off.SetActive (false);
        }
    }

这是我的musicToogle功能.在每个场景中，音乐都会重新开始；在每个场景中，当我想要打开/关闭音乐时，我都会单击一个部署此代码的按钮.但是，我不希望音乐在每个场景更改时都重新开始，我希望恢复播放，并且希望能够控制每个场景中的音乐(打开/关闭).我怎样才能做到这一点 ?

This is my musicToogle function. In every scene the music restarts, and in every scene when I want to turn on/off the music, I click a button which deploys this code. However, I don't want the music to restart every scene change, I want it to resume, and I want to be able to control the music(turn on/off) in every scene. How can I do this ?

推荐答案

我的答案假设musicPlayer变量是 AudioSource .

My answer assumes that musicPlayer variable is a type of AudioSource.

实际上有两种方法可以做到这一点:

There are really two ways to do this:

1 .

使用musicPlayer.Pause();暂停，然后播放音乐，然后使用musicPlayer.UnPause();取消暂停.这样可以确保音乐恢复播放，而不是重新开始播放.

Use musicPlayer.Pause(); to pause then music then use musicPlayer.UnPause(); to un-pause it. This will make sure that the music resumes instead of restarting it.

在这种情况下，请在每个GameObject中将DontDestroyOnLoad(gameObject);与AudioSource一起使用，以使它们在下一场景中不会被破坏.

In this case, you use DontDestroyOnLoad(gameObject); on each GameObject with the AudioSource so that they are not destroyed when you are on the next scene.

2 .存储AudioSource.time值.下次加载它，然后将其应用到AudioSource上，然后再播放.

2.Store the AudioSource.time value. Load it next time then apply it to the AudioSource before playing it.

您可以使用PlayerPrefs来执行此操作，但是我更喜欢使用json和

You can use PlayerPrefs to do this but I prefer to store with json and the DataSaver class.

保存:

AudioSource musicPlayer;
AudioStatus aStat = new AudioStatus(musicPlayer.time);
//Save data from AudioStatus to a file named audioStat_1
DataSaver.saveData(aStat, "audioStat_1");

加载:

AudioSource musicPlayer;
AudioStatus loadedData = DataSaver.loadData<AudioStatus>("audioStat_1");
if (loadedData == null)
{
    return;
}
musicPlayer.time = loadedData.audioTime;
musicPlayer.Play();

您的AudioStatus课:

[Serializable]
public class AudioStatus
{

    public float audioTime;

    public AudioStatus(float currentTime)
    {
        audioTime = currentTime;
    }
}
