声音系统，管理音效

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SoundManager : SingletonMono<SoundManager>
{private AudioSource backgroundMusic = null;private float backgroundValue = 1;private float soundValue = 1;private GameObject soundObj = null;private List<AudioSource> soundList = new List<AudioSource>();public SoundManager(){MonoMgr.GetInstance().AddUpdateListener(SoundUpdate);}public void SoundUpdate(){for (int i = soundList.Count - 1; i > 0; i--){if (!soundList[i].isPlaying){GameObject.Destroy(soundList[i]);soundList.RemoveAt(i);}}}public void PlayBackgroundMusic(string name){if (backgroundMusic == null){GameObject obj = new GameObject("backgroundMusic");backgroundMusic = obj.AddComponent<AudioSource>();}//异步加载背景音乐并且加载完成后播放ResManager.GetInstance().LoadAysnc<AudioClip>("Music/" + name, (clip) =>{backgroundMusic.clip = clip;backgroundMusic.loop = true;backgroundMusic.volume = backgroundValue;backgroundMusic.Play();});}public void ChangeBackgroundMusicValue(float v){backgroundValue = v;if (backgroundMusic == null)return;backgroundMusic.volume = backgroundValue;}public void PauseBackgroundMusic(){if (backgroundMusic == null)return;backgroundMusic.Pause();}public void StopBackgroundMusic(){if (backgroundMusic == null)return;backgroundMusic.Stop();}public void PlaySound(string name, bool isLoop, Action<AudioSource> callback = null){if (soundObj == null){soundObj = new GameObject();soundObj.name = "Sounds";}AudioSource source = soundObj.AddComponent<AudioSource>();ResManager.GetInstance().LoadAysnc<AudioClip>("Music/" + name, (clip) =>{source.clip = clip;source.loop = isLoop;source.volume = soundValue;source.Play();//音效异步加载结束后，将这个音效组件加入集合soundList.Add(source);if (callback != null)callback(source);});}public void ChangeSoundValue(float v){soundValue = v;for (int i = 0; i < soundList.Count; i++){soundList[i].volume = v;}}public void StopSound(AudioSource source){if (soundList.Contains(source)){soundList.Remove(source);source.Stop();GameObject.Destroy(source);}}}

核心：

1.背景音乐：专门的AudioSource存储bgm，在调用方法后创建声音对象。

2.普通音效：list存储audiosource，在调用后通过update检查是否播放完毕，播放完毕则移除list并销毁。

测试: 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SoundTest : MonoBehaviour
{private bool isPlayBackgroundMusic = false;private bool isPlaySound = false;// Update is called once per framevoid Update(){if (Input.GetMouseButtonDown(0) && !isPlayBackgroundMusic){isPlayBackgroundMusic = true;SoundManager.GetInstance().PlayBackgroundMusic("BGM");}if (Input.GetMouseButtonDown(0) && !isPlaySound){isPlaySound = true;SoundManager.GetInstance().PlaySound("BGM", false);}}
}
