unity AudioSource播放完声音后要执行的函数或条件操作-C#/.NET开发

这篇文章主要介绍了unity AudioSource播放完声音后要执行的函数或条件操作，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

将脚本挂在要判断声音是否播放完毕的物体上


using System.Collections;
using UnityEngine;
using UnityEngine.Events;
[RequireComponent(typeof(AudioSource))]
public class AudioManager : MonoBehaviour
{
public static AudioManager instence = null;
private AudioSource _audio;
void Awake()
{
if (instence == null)
{
instence = this;
}
}
void Start()
{
    _audio = GetComponent<AudioSource>();
  
}
void Update()
{
//按下键盘按钮A键执行函数播放语音
if (Input.GetKeyDown(KeyCode.A))
{
PlayAudio（GameObject.GetComponent().clip）
}
}
//接受音频文件和是否重复播放
public void PlayAudio(AudioClip clip, UnityAction callback = null, bool isLoop = false)
{
//获取自身音频文件进行播放并且不重复播放
_audio.clip = clip;
_audio.loop = isLoop;
_audio.Play();
//执行协成获取音频文件的时间
StartCoroutine(AudioPlayFinished(_audio.clip.length, callback));
}
//执行协成函数 并且返回时间
private IEnumerator AudioPlayFinished(float time, UnityAction callback)
{   
    yield return new WaitForSeconds(time);
    //声音播放完毕后之下往下的代码  
    # region   声音播放完成后执行的代码
    print("声音播放完毕，继续向下执行"); 
    #endregion
}
}

补充：Unity 的 AudioSourse 播完的监听

最近涉及到音频结束后的调用问题，unity 原生的音频组件 AudioSourse 没有功能，于是自己写了一个。

下面是代码：


using Assets.Scripts.Entities;
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine; 
public class AudioSourceInfo
{
    private float playTime = 0;
    public AudioSource AudioSource { get; private set; }
    public AudioState AudioState = AudioState.Idle;
    public Action AfterPlaying { get; set; }
    public int ID = 0;
    public AudioSourceInfo(GameObject go)
    {
        this.AudioSource = go.AddComponent<AudioSource>();
    }
    public AudioClip Clip
    {
        get
        {
            return this.AudioSource.clip;
        }
        set
        {
            this.AudioSource.clip = value;
            playTime = 0;
        }
    }
    public bool Loop
    {
        get
        {
            return this.AudioSource.loop ;
        }
        set
        {
            this.AudioSource.loop = value;
        }
    }
    public float Volume
    {
        get
        {
            return this.AudioSource.volume;
        }
        set
        {
            this.AudioSource.volume = value;
        }
    }
    public void Play()
    {
        if (null == this.AudioSource)
        {
            return;
        }
        this.AudioState = AudioState.IsPlaying;
        this.AudioSource.Play();
    }
    public void Pause()
    {
        if (null == this.AudioSource)
        {
            return;
        }
        if(this.AudioSource.isPlaying)
        {
            this.AudioState = AudioState.Pause;
            this.AudioSource.Pause();
        }
    }
    public void Stop()
    {
        if (null == this.AudioSource)
        {
            return;
        }
        this.AudioState = AudioState.Stop;
        this.AudioSource.Stop();
        if(AfterPlaying!= null)
        {
            this.AfterPlaying();
        }
    }
    private void Update()
    {
        if (this.AudioSource != null &&  this.AudioSource.clip!= null && this.AudioState == AudioState.IsPlaying)
        {
            playTime += Time.fixedDeltaTime;
            if (playTime >= this.Clip.length)
            {
                playTime = 0;
                this.Stop();
            }
        }
    }
} 
public enum AudioState
{
    Idle,
    IsPlaying,
    Pause,
    Stop,
}

补充：Unity3d AudioSource如何监听播放完成并处理逻辑

想知道AudioSource什么时候播放完成并处理相关的逻辑，比如切换曲目，而unity又没有提供相应的事件
