Question

到目前为止，我有一个立方体，Y刻度对正在播放的音乐作出反应，但它的运动是非常零星的，一秒钟它将非常高，而下一个非常低。我怎样才能使它只取最高值并按比例缩放，然后慢慢向下移动到初始比例，除非调用高于其当前比例的另一个值。

public class _FFT_Obstacles : MonoBehaviour {

public GameObject cube01;
public GameObject cube02;
public GameObject cube03;
public GameObject cube04;
public GameObject cube05;

private float juice = 40f;
private float speed = 5f;

public float[] spec;

public float specMag01;
public float specMag02;
public float specMag03;
public float specMag04;
public float specMag05;

private Vector3 localScale;
private Vector3 newScale;
//The velocity that the cubes will drop  
private Vector3 gravity = new Vector3(0.0f, 0.25f, 0.0f);

// Use this for initialization
void Start()
{
    localScale = cube01.gameObject.transform.localScale;
}

// Update is called once per frame
void Update()
{
    spec = AudioListener.GetSpectrumData(64,0,FFTWindow.Hamming); // this works on audio source
   // spec = AudioListener.GetOutputData(64, 0);  // this gives much  better values.

    specMag01 = spec[2] + spec[4];
    specMag02 = spec[12] + spec[14];
    specMag03 = spec[22] + spec[24];
    specMag04 = spec[32] + spec[34];
    specMag05 = spec[57] + spec[60];

    lerpScale();

    cube01.gameObject.transform.localScale = new Vector3(1f, 1f + (specMag01 * juice), 1f);
    //cube02.gameObject.transform.localScale = new Vector3(1f, 1f + (specMag01 * juice), 1f);
    //cube03.gameObject.transform.localScale = new Vector3(1f, 1f + (specMag01 * juice), 1f);
    //cube04.gameObject.transform.localScale = new Vector3(1f, 1f + (specMag01 * juice), 1f);
    //cube05.gameObject.transform.localScale = new Vector3(1f, specMag05 * juice, 1f);
}

void lerpScale()
{
   newScale = cube01.gameObject.transform.localScale = new Vector3(1f, 1f + (specMag01 * juice), 1f);
  //  cube01.gameObject.transform.localScale = Vector3.Lerp(originalScale, newScale, Time.deltaTime * speed);
   // newScale.Set(1f, cube01.gameObject.transform.localScale.y, 1f);

    if (newScale.y >= localScale.y)
    {
        localScale.y = newScale.y;
    }
    else
    {
        localScale.y -= gravity.y;
    }
}

}

    public float[] spec;

    public float specMag01;
    public float specMag02;
    public float specMag03;
    public float specMag04;
    public float specMag05;

    private void Update()
    {
        spec = AudioListener.GetSpectrumData(64, 0, window); // this works on audio source
        // spec = AudioListener.GetOutputData(64, 0);  // this gives much  better values.

        specMag01 = spec[2] + spec[4];
        specMag02 = spec[12] + spec[14];

        UpdateCubeScale(cube04, specMag04);

    }

    private void UpdateCubeScale(GameObject cube, float specMag)
    {
        var currentScale = cube.transform.localScale;
        var newScale = new Vector3(1f, 1f + (specMag * juice), 1f);

        if (newScale.y < currentScale.y)
        {
            newScale.y = currentScale.y - falloff * Time.deltaTime;
        }

        if (newScale.y < 0f)

            newScale.y = 0f;
        }

        cube.transform.localScale = newScale;
    }
}
