Unity3D閃光燈效果的實現程式碼：

using UnityEngine;
using System.Collections;

//定義一個Light類
public class Light : MonoBehaviour {
    //定義一個時間長度
    public float duration = 1.0F;
    //定義一個紅色（顏色自取）
    public Color colorRed = Color.red;
    //定義一個藍色（顏色自取）
    public Color colorBlue = Color.blue;

    // Update is called once per frame
 

    void Update () {
        float phi = Time.time / duration * 2 * Mathf.PI;

        //使用數學函式來實現閃光燈效果
        float amplitude = Mathf.Cos(phi) * 0.5F + 0.5F;
        light.intensity = amplitude;
        float x = Mathf.PingPong (Time.time, duration) / duration;
        light.color = Color.Lerp (colorRed, colorBlue, x);
    }
}
