Unity音效系统控制

unity可设置audiosource组件对象添加音源，通过audioClip来获取音效。

这是一个用来控制播放的soundmanager。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SoundManager : MonoBehaviour
{
    public AudioSource efxSource;
    public AudioSource musicSource;
    public static SoundManager instance = null;
    public float lowPitchRange = 0.95f;
    public float highPitchRange = 1.05f;

    void Start()
    {
        if (instance == null)
            instance = this;
        else if (instance == this)
            Destroy(gameObject);

        DontDestroyOnLoad(gameObject);
    }

    public void PlaySingle(AudioClip clip)
    {
        efxSource.clip = clip;
        efxSource.Play();
    }

    public void RandomizeSfx(params AudioClip[] clips)//params是一个计算机函数，表示函数的参数是可变个数的，即可变的方法参数，就像DELPHI 里 WRITELN 函数一样，用于表示类型相同，但参数数量不确定。例如，params(int a) 
    {
        int randomIndex = Random.Range(0, clips.Length);
        float randomPitch = Random.Range(lowPitchRange, highPitchRange);

        efxSource.pitch = randomPitch;
        efxSource.clip = clips[randomIndex];
        efxSource.Play();
    }
}
