Question

我正在Unity3d上开发一款游戏。在这里我有5张牌，而我正试图用震动来移动它们，但是，在我的代码中，当执行摇动时卡片正在洗牌，我需要该功能可以延迟或在摇动结束时开始。这是我的代码：

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class Shake1 : MonoBehaviour {

    int numTimes = 50;

    public Image personajes;
    public Image lugares;
    public Image situaciones;
    public Image emociones;
    public Image objetos;
    public GameObject camShake;


    float accelerometerUpdateInterval;
    // The greater the value of LowPassKernelWidthInSeconds, the slower the filtered value will converge towards current input sample (and vice versa).
    float lowPassKernelWidthInSeconds;
    // This next parameter is initialized to 2.0 per Apple's recommendation, or at least according to Brady! ;)
    float shakeDetectionThreshold ;

    float lowPassFilterFactor;

    Vector3 lowPassValue;
    Vector3 acceleration;
    Vector3 deltaAcceleration;

    void Start () {
        lowPassKernelWidthInSeconds = 1.0f;
        accelerometerUpdateInterval = 1.0f / 60.0f;
        lowPassValue  = Vector3.zero;
        lowPassFilterFactor = accelerometerUpdateInterval / lowPassKernelWidthInSeconds;
    }
    public Vector3 LowPassFilter(Vector3 newSample){
        lowPassValue = Vector3.Lerp (lowPassValue, newSample,lowPassFilterFactor);
        return lowPassValue;    
    }

    void Update () {
        acceleration = Input.acceleration;
        deltaAcceleration = acceleration - LowPassFilter (acceleration);

        if (Mathf.Abs (deltaAcceleration.x) >= 0.2 && Mathf.Abs (deltaAcceleration.y) >= 0.2 && Mathf.Abs (deltaAcceleration.z) >= 0.2) {
            for (int i = 0; i < numTimes; i++) {
                Handheld.Vibrate();
                if (personajes.transform.parent.name == "Panel_Superior") {
                    personajes.sprite = Resources.Load<Sprite> ("Cartas/pillow-cards-" + Random.Range (2, 13)) as Sprite;
                }
                if (situaciones.transform.parent.name == "Panel_Superior") {
                    situaciones.sprite = Resources.Load<Sprite> ("Cartas/pillow-cards-" + Random.Range (28, 39)) as Sprite;
                }
                if (emociones.transform.parent.name == "Panel_Superior") {
                    emociones.sprite = Resources.Load<Sprite> ("Cartas/pillow-cards-" + Random.Range (41, 52)) as Sprite;
                }
                if (lugares.transform.parent.name == "Panel_Superior") {
                    lugares.sprite = Resources.Load<Sprite> ("Cartas/pillow-cards-" + Random.Range (15, 26)) as Sprite;
                }
                if (objetos.transform.parent.name == "Panel_Superior") {
                    objetos.sprite = Resources.Load<Sprite> ("Cartas/pillow-cards-" + Random.Range (54, 68)) as Sprite;
                }
            }
        }
    }

}

当Update()以60Hz调用时，您可以创建一个计数器（让我们称之为zeroAcc），每当加速度低于触发阈值时，该计数器就会增加＆＃34;摇＆＃34 ;.
在触发震动的同时，您可以在此时存储zeroAcc的值，让我们说accTri。
现在你需要决定延迟，这个例子可以是Update()的30次调用，然后触发回调。
它看起来像这样：

void Update(){
//keep your code you already have and add this:
    if (zeroAcc - accTri > 30) {
        callback ();
        accTri = int.MaxValue; //we don't want to trigger again
    }
}

在处理设备结束抖动后如何延迟功能？
