标题: unity3d中脚本运行顺序的个人研究(荐)
为一个场景对象添加上三个脚本，在场景开始运行时，脚本中的Start方法将会按照脚本添加的顺序来依次运行，而Update方法却是完全相反

   比如：有A1、A2、A3三个脚本，它们的添加顺序是A1、A3、A2，那么在场景运行时，程序运行顺序是A1.Start()、A3.Start()、 A2.Start()、A2.Update()、A3.Update()、A1.Update()……，即使A1.Start()或A2.Update ()运算时间超过其它的方法，那么其它的方法也会等待其运行完成后才会开始运行之……

下面是三个脚本文件的例程：

jxxh01.cs

using UnityEngine;

using System.Collections;

public class jxxh01 : MonoBehaviour

{

// Use this for initialization

void Start()

{

   for (int temp02 = 0; temp02 < 5; temp02++)

   {

      for (int temp01 = 0; temp01 < 5; temp01++)

      {

         int a01 = 0;

         for (int temp = 0; temp < 50000; temp++)

         {

               a01++;

               a = a01;

         }

         a01 = 0;

      }

   }

   print(Time.time + " This is jxxh01 : " + a);

}

public int ForValue=10000;

int a = 0;

// Update is called once per frame

void Update () {

   for (int temp = 0; temp < ForValue; temp++) { a = temp; }

   print(Time.time + " This is jxxh01 : " + a);

}

}

jxxh02.cs

using UnityEngine;

using System.Collections;

public class jxxh02 : MonoBehaviour

{

   // Use this for initialization

void Start()

{

   for (int temp = 0; temp < 10000; temp++)

   {

      a++;

   }

   print(Time.time + " This is jxxh02 : " + a);

}

public int ForValue = 100;

int a = 0;



   // Update is called once per frame

   void Update () {



   print(Time.time + " This is jxxh02 : " + a);

   }

}

jxxh03.cs

using UnityEngine;

using System.Collections;

public class jxxh03 : MonoBehaviour

{

   // Use this for initialization

void Start()

{

   for (int temp = 0; temp < 10000; temp++)

   {

      a++;

   }

   print(Time.time + " This is jxxh03 : " + a);

}

public int ForValue = 100;

int a = 0;



   // Update is called once per frame

   void Update () {



   print(Time.time + " This is jxxh03 : " + a);

   }

}
