播放游戏音频的类（AudioSource）

using System.Collections;

using UnityEngine;

public class NO17AudioSource : MonoBehaviour
{
    private AudioSource audioSource;//音频组件
    public AudioClip clip;//音频文件
    public AudioClip clip2;
    bool mutestate;
    bool pausestate;
    // Start is called before the first frame update
    void Start()
    {
        audioSource = GetComponent<AudioSource>();
        audioSource.clip = clip;
        audioSource.Play();
        //设置音乐的播放开始的时间轴位置
        audioSource.time = 3;
    }

    // Update is called once per frame
    void Update()
    {
        //实现按下W键静音，再次按下恢复音量
        if (Input.GetKeyDown(KeyCode.W))
        {
            mutestate = !mutestate;
            audioSource.mute = mutestate;
        }
        if (Input.GetKeyDown(KeyCode.P))
        {
            pausestate = !pausestate;
            //暂停播放
            if (pausestate)
            {
                audioSource.Pause();
            }
            else
            {
                //继续播放
                audioSource.UnPause();
            }
        }
        //停止播放
        if (Input.GetKeyDown(KeyCode.S))
        {
            audioSource.Stop();
        }
        //播放一次
        if (Input.GetKeyDown(KeyCode.K))
        {
            audioSource.PlayOneShot(clip2);
        }
        //静态方法
        //在指定位置创建音频
        if (Input.GetKeyDown(KeyCode.Q))
        {
            AudioSource.PlayClipAtPoint(clip2,transform.position);
        }
    }
}

注：

1. audioSource.Stop()这个函数一旦执行就停止音频播放，想要重新播放音频就只有执行audioSource.Play()这条命令

2. 使用音频文件的前提是，要在相应的组件上装AudioListener组件
