Unity获取麦克风音量（实现音效波浪效果）

1.每个方块（Cube）为一个波浪添加脚本MusicDance

2.整体获取马克风音量大小脚本MusicManager

MusicDance

public class MusicDance : MonoBehaviour{    private float targetPosY;    private float speed;    [HideInInspector]public bool isDance;    void Start()    {        RandomTargetPosY();    }    void Update()    {        if (isDance)        {            if (Mathf.Abs(transform.localScale.y - targetPosY) >= 1f)            {                transform.localScale = new Vector3(1, Mathf.SmoothDamp(transform.localScale.y, targetPosY, ref speed, Random.Range(0.2f,1f)), 1);            }            else            {                RandomTargetPosY();            }        }        else        {            //没有声音时,从当前高度下落到正常高度            if (Mathf.Abs(transform.localScale.y - targetPosY) >= 0.1f)            {                transform.localScale = new Vector3(1, Mathf.SmoothDamp(transform.localScale.y, 1f, ref speed, Random.Range(0.2f, 1f)), 1);            }        }    }    void RandomTargetPosY()    {        targetPosY = UnityEngine.Random.Range(1f, 12f);    }}

MusicManager

public class MusicManager : MonoBehaviour{    [SerializeField]private MusicDance[] musicDances;    private AudioClip audioClip;    private string strs;    private void Awake()    {        audioClip = Microphone.Start(strs, true, 999, 44100);        strs = Microphone.devices[0];    }    void Start()    {            }    private void Update()    {        for (int i = 0; i < musicDances.Length; i++)        {            musicDances[i].isDance = DanceOrNot();        }    }    bool DanceOrNot()    {        float[] datas = new float[128];        int startPos = Microphone.GetPosition(strs) - 127;        if (startPos < 0) return false;        audioClip.GetData(datas, startPos);        float max = -1f;        for (int i = 0; i < datas.Length; i++)        {            if (max < datas[i])            {                max = datas[i];            }        }        max *= 1000;        if (max > 20)        {            return true;        }        else        {            return false;        }     }}
