C#不会循环响应的Action设计与实现

一、简述

特点：

不光是能防止直接的死循环调用；
还能防止间接的死循环调用；
还支持对不同参数判定，不同参数的调用可以不当循环调用；

消息事件系统中必备，拒绝死循环
简明、高效、实用
其它编程语言也可以参考实现

二、测试代码

测试代码只为展示组件功能，也完美的展示组件功能。测试用例是完全的

using UnityEngine;namespace Main
{/// <summary>/// 将脚本挂到一个空对象上即可测试/// </summary>public class SimpleTest_NonLoopAction : MonoBehaviour{private void Start(){// 测试逻辑: [->A ->A]Logic01.Run();// 测试逻辑：[->A ->B ->C ->A]Logic02.Run();// 测试逻辑：[->A ->A(1) ->A(1,2) ->A(1,2,3) ->A(1)]// (注：中间相同的消息但参数不一样，只有出现一样的参数的消息，都会中断)Logic03.Run();}static class Logic01{static NonLoopAction _nonLoopActionA;/// <summary>/// 执行逻辑 [->A ->A]/// </summary>public static void Run(){Debug.Log("===== Logic01: [->A ->A] ===========");_nonLoopActionA = new NonLoopAction(OnResponseA, "A消息响应者", true);_nonLoopActionA.Invoke();}static void OnResponseA(params object[] args){Debug.Log("==> On Response A");_nonLoopActionA.Invoke();}}static class Logic02{static NonLoopAction _nonLoopActionA;static NonLoopAction _nonLoopActionB;static NonLoopAction _nonLoopActionC;/// <summary>/// 执行逻辑:[->A ->B ->C ->A]/// </summary>public static void Run(){Debug.Log("===== Logic02: [->A ->B ->C ->A] ===========");_nonLoopActionA = new NonLoopAction(OnResponseA, "A消息响应者", true);_nonLoopActionB = new NonLoopAction(OnResponseB, "B消息响应者", true);_nonLoopActionC = new NonLoopAction(OnResponseC, "C消息响应者", true);_nonLoopActionA.Invoke();}static void OnResponseA(params object[] args){Debug.Log("==> On Response A");_nonLoopActionB.Invoke();}static void OnResponseB(params object[] args){Debug.Log("==> On Response B");_nonLoopActionC.Invoke();}static void OnResponseC(params object[] args){Debug.Log("==> On Response C");_nonLoopActionA.Invoke();}}static class Logic03{static NonLoopAction _nonLoopActionA;/// <summary>/// 执行逻辑：[->A ->A(1) ->A(1,2) ->A(1,2,3) ->A(1)]/// (注：中间相同的消息但参数不一样，只出现一样的参数的消息，都会中断)/// </summary>public static void Run(){Debug.Log("===== Logic03: [->A ->A(1) ->A(1,2) ->A(1,2,3) ->A(1)] ===========");_nonLoopActionA = new NonLoopAction(OnResponseA, "A消息响应者", true);_nonLoopActionA.Invoke();//A}static void OnResponseA(params object[] args){Debug.Log("==> On Response A");int args_count = args.Length;if (args_count == 0){_nonLoopActionA.Invoke(1);//A(1)}else if (args_count == 1){_nonLoopActionA.Invoke(1,2);//A(1,2)}else if (args_count == 2){_nonLoopActionA.Invoke(1,2,3);//A(1,2,3)}else if (args_count == 3){_nonLoopActionA.Invoke();//A}}}}
