Coroutine 协同程序

 Coroutine  StartCoroutine (routine : IEnumerator) :该方法返回 Coroutine  类型的值。

例子：执行协同，只在场景开始时运行一次。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	IEnumerator Start() {
		print("Starting " + Time.time);
		yield return StartCoroutine(WaitAndPrint(2.0F));
		print("Done " + Time.time);
	}
	IEnumerator WaitAndPrint(float waitTime) {
		yield return new WaitForSeconds(waitTime);
		print("WaitAndPrint " + Time.time);
	}
}

需求：在条件中，执行。满足条件即可：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
public class DelayToInvoke : MonoBehaviour {

    public static IEnumerator DelayToInvokeDo(Action action01,Action action02, float delaySeconds)
   {
   	 action01();
     yield return new WaitForSeconds(delaySeconds);
     action02();
   }
}

在条件中执行下一句即可：

StartCoroutine(DelayToInvoke.DelayToInvokeDo(() =>
                     {
                     NGUITools.SetActive(dongwulight,true);
                   },() =>{
                     NGUITools.SetActive(dongwulight,false);
                   }, 3.0f));//3秒之后执行第二个函数 NGUITools.SetActive(dongwulight,false)

注意方法:

 StartCoroutine();

DelayToInvoke.DelayToInvokeDo()方法中参数格式：()=>{},()=>{},delaySeconds

A aGetLambda = () => a;//等价于()=>{return a;}
