StrangeIOC特性介紹

Strange框架的目的是為了在混亂的Unity項目代碼中，設計支持響應式編程設計模式
Strange框架中提供的特性大部分都是可選性的

使用EventDispatcher完成事件分發功能

EventDispatcher是strange框架內的默認分發系統。將會有Signals信號能夠添加到一個分發系統內。

EventDispatcher的使用步驟

• 創建EventDispatcher對象

  private EventDispatcher dispatcher = new EventDispatcher();
  

• 添加Listener監聽對象

  void Start () {
      //當遇到分發的事件為'Fire'時,會自動調用CallBack事件
      dispatcher.AddListener ("Fire", ((IEvent payload) => {
          Debug.Log(payload.data);
      }));
  }
  

• 分發Fire類型的字符串

  //UGUI按鈕完成點擊事件
  public void DidClickButton()
  {
      dispatcher.Dispatch ("Fire", "點擊了按鈕");
  }
  

• 刪除響應的監聽者Listener

  dispatcher.RemoveListener ("Fire", ecb);
  

完成一個具體的需求

當程序內的一個游戲對象需要通過鍵盤控制時，我們可以通過如下代碼完成功能

• HHGameController.cs

      using UnityEngine;
      using System.Collections;
      using strange.extensions.dispatcher.eventdispatcher.impl;
      using strange.extensions.dispatcher.eventdispatcher.api;
  
      public class HelloView : MonoBehaviour {
  
          // Use this for initialization
          //指定物體對象
          public HHPlayer Player;
  
          //當前事件對象
          private Event e;
          void OnGUI()
          {
              e = Event.current;
  
              if (e == null) {
                  return;
              }
  
              Player.Dispatcher.Dispatch (e.keyCode);
          }
      }
  

• HHPlayer.cs

      using UnityEngine;
      using System.Collections;
      using strange.extensions.dispatcher.eventdispatcher.impl;
      using strange.extensions.dispatcher.eventdispatcher.api;
  
      public class HHPlayer:MonoBehaviour
      {
          private EventDispatcher _dispatcher = null;
          public EventDispatcher Dispatcher{
              get{ 
                  if (_dispatcher == null) {
                      _dispatcher = new EventDispatcher ();
                  }
  
                  return _dispatcher;
              }
          }
  
          void Start()
          {
              this.InitDispatcher ();
          }
  
          private void InitDispatcher()
          {
              EventCallback vertical_callback = ((IEvent payload) => {
                  Vector3 translate = new Vector3 ();
                  translate.x = 0f;
                  translate.y = 0f;
                  translate.z = Input.GetAxis ("Vertical") * 0.03f;
                  this.transform.Translate (translate);
              });
  
              EventCallback horizontal_callback = ((IEvent payload) => {
  
                  Vector3 rotate = new Vector3();
                  rotate.x = 0f;
                  rotate.y = 1f;
                  rotate.z = 0f;
                  this.transform.Rotate(rotate,Input.GetAxis("Horizontal"));
              });
  
              this.Dispatcher.AddListener (KeyCode.W, vertical_callback);
              this.Dispatcher.AddListener (KeyCode.S, vertical_callback);
              this.Dispatcher.AddListener (KeyCode.A, horizontal_callback);
              this.Dispatcher.AddListener (KeyCode.D, horizontal_callback);
          }
      }
