今天去面试..面试官竟然说子线程的Action不能发送到主线程执行... ...废话不说上干货
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using System.Threading;
public class ActionDemo : MonoBehaviour {
public static List<Action<string>> actionlist = new List<Action<string>>();
void Start()
{
actionlist.Add( curname => {
Debug.Log ("action1 :" + curname);
});
actionlist.Add( curname => {
Debug.Log ("action2 :" + curname);
});
//开启子线程
Thread th = new Thread(ThreadChild);
th.Start();
}
static void ThreadChild()
{
//循环三次 关闭线程,养成良好习惯
for (int i = 0; i < 3; i++) {
//锁住保证线程安全
lock(actionlist){
actionlist.Add( curname => {
//这里填子线程中 想去主线程调用的代码 ,例如改变UI
Debug.Log ("ThreadChild :" + curname);
});
Thread.Sleep(1000);
}
}
}
void Update(){
//遍历action 在Update中调用action自然是主线程调用
for (int i = 0; i < actionlist.Count; i++) {
ActionDemo.actionlist [i] (Time.time+"");
}
actionlist.Clear();
}
}
