unity AudioSource播放完聲音后要執(zhí)行的函數(shù)或條件操作

這篇文章主要介紹了unity AudioSource播放完聲音后要執(zhí)行的函數(shù)或條件操作，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

將腳本掛在要判斷聲音是否播放完畢的物體上

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()
{
//按下鍵盤按鈕A鍵執(zhí)行函數(shù)播放語音
if (Input.GetKeyDown(KeyCode.A))
{
PlayAudio（GameObject.GetComponent().clip）
}
}
//接受音頻文件和是否重復(fù)播放
public void PlayAudio(AudioClip clip, UnityAction callback = null, bool isLoop = false)
{
//獲取自身音頻文件進(jìn)行播放并且不重復(fù)播放
_audio.clip = clip;
_audio.loop = isLoop;
_audio.Play();
//執(zhí)行協(xié)成獲取音頻文件的時間
StartCoroutine(AudioPlayFinished(_audio.clip.length, callback));
}
//執(zhí)行協(xié)成函數(shù) 并且返回時間
private IEnumerator AudioPlayFinished(float time, UnityAction callback)
{   
    yield return new WaitForSeconds(time);
    //聲音播放完畢后之下往下的代碼  
    # region   聲音播放完成后執(zhí)行的代碼
    print("聲音播放完畢，繼續(xù)向下執(zhí)行"); 
    #endregion
}
}

補(bǔ)充：Unity 的 AudioSourse 播完的監(jiān)聽

最近涉及到音頻結(jié)束后的調(diào)用問題，unity 原生的音頻組件 AudioSourse 沒有功能，于是自己寫了一個。

下面是代碼：

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,
}

補(bǔ)充：Unity3d AudioSource如何監(jiān)聽播放完成并處理邏輯

想知道AudioSource什么時候播放完成并處理相關(guān)的邏輯，比如切換曲目，而unity又沒有提供相應(yīng)的事件
