(一)多线程的创建
Thread t = new Thread(new ThreadStart(Go));
Thread t1 = new Thread(Go);
两种创建方式没有区别;
(二)多线程的状态控制和优先级
多线程有4种状态:Start()开始;Abort()终止;Join()阻塞;Sleep()休眠;
有5种优先级:从高到底依次为:Highest,AboveNormal ,Normal ,BelowNormal ,Lowest;
线程的默认优先级为Normal;
多线程实例
- /*
- *
- * 游戏多线程
- * */
- using UnityEngine;
- using System.Threading;
- public class BaseThread{
- private static BaseThread instance;
- object obj = new object();
- int num = 0;
- private BaseThread()
- {
- /*测试线程优先级
- /*/
- Thread th1 = new Thread(Th_test1); //创建一个线程
- Thread th2 = new Thread(Th_test2);
- Thread th3 = new Thread(Th_test3);
- th1.Start();
- th2.Start();
- th3.Start();
- //学习优先级
- th1.Priority = System.Threading.ThreadPriority.Highest; //优先级最高
- th2.Priority = System.Threading.ThreadPriority.Normal;
- th3.Priority = System.Threading.ThreadPriority.Lowest;
- //**/
- ///*测试线程锁
- /*/
- Thread th1 = new Thread(new ThreadStart(Th_lockTest));
- th1.Name = "test1";
- th1.Start();
- Thread th2 = new Thread(new ThreadStart(Th_lockTest));
- th2.Name = "test2";
- th2.Start();
- //*/
- }
- public static BaseThread GetInstance()
- {
- if (instance == null)
- {
- instance = new BaseThread();
- }
- return instance;
- }
- //测试多线程锁
- public void Th_lockTest()
- {
- Debug.Log("测试多线程");
- while (true)
- {
- lock (obj)
- { //线程“锁”
- num++;
- Debug.Log(Thread.CurrentThread.Name + "测试多线程" + num);
- }
- Thread.Sleep(100);
- if (num > 300)
- {
- Thread.CurrentThread.Abort();
- }
- }
- }
- //测试多线程优先级
- public void Th_test1()
- {
- for (int i = 0; i < 500; i++)
- {
- Debug.Log("测试多线程1执行的次数:" + i);
- if(i >200)
- {
- Thread.CurrentThread.Abort();
- }
- }
- }
- public void Th_test2()
- {
- for (int i = 0; i < 500; i++)
- {
- Debug.Log("测试多线程2执行的次数:" + i);
- if (i > 300)
- {
- Thread.CurrentThread.Abort();
- }
- }
- }
- public void Th_test3()
- {
- for (int i = 0; i < 500; i++)
- {
- Debug.Log("测试多线程3执行的次数:" + i);
- if (i > 400)
- {
- Thread.CurrentThread.Abort();
- }
- }
- }
- }
注意:
1,当多个线程同时访问同一数据时要加线程锁lock。
- Object n=new Object();
- long shu = 0;
- // Use this for initialization
- void Start () {
- }
- // Update is called once per frame
- void Update ()
- {
- lock (n)
- {
- xian = 1;
- }
- }
