當遊戲的某一對象屬性改變時,全局需要用到或已經註冊該屬性的地方都要即時改變,EventSystem使用通過事件監聽的方法,實現了即時更新屬性的功能

基本框架圖解如下:

實現該功能的步驟如下:

1. 需要引用以下三個腳本,(來源於GameFrameWork的GameMain\Scripts\Event文件夾)

2.在EventKey中寫入需要註冊事件系統的屬性(作為事件監聽的索引鍵值,單一類),例如:

3.創建一個玩家屬性腳本(即圖解中的屬性管理區);例如

 1 using System.Collections;
 2 using
 
 System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class PlayerInfoManagerTest
 6 {
 7     #region 單例模式
 8     private static PlayerInfoManagerTest instance;
 9 
10     public static PlayerInfoManagerTest Instance
11     {
12         get
13         {
14             if (instance == null)
 
15             {
16                 instance = new PlayerInfoManagerTest();
17             }
18             return instance;
19         }
20     }
21     private PlayerInfoManagerTest() { }
22     #endregion
23 
24 
25     private int playerGold;
26 
27     private string playerName;
28 
29     public
 
 int PlayerGold
30     {
31         get { return playerGold; }
32         set
33         {
34             //之前玩家金幣數值  !=  設置過來的數值
35             if (playerGold != value)
36             {
37                 playerGold = value;
38                 //數值發生變化  通知註冊當前 金幣發生變化的 界面
39                 EventDispatcher.TriggerEvent<int>(EventKeyTest.OnPlayerGoldChange, playerGold);
40 
41             }
42         }
43     }
44     public string PlayerName {
45         get { return playerName; }
46         set {
47             //if (!playerName.Equals(true))          
48             if (playerName!=value)
49             {
50                 playerName = value;
51                 EventDispatcher.TriggerEvent<string>(EventKeyTest.OnPlayerNameChage, playerName);
52             }
53         }
54     }
55 }

4.創建事件管理腳本,用於註冊事件,並寫入事件發生時執行的方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;


public class EventTest : MonoBehaviour {

    public Text goldText;
    public Text playerNameText;

    private string[] names = {"張三","李四","王五","趙柳","二哈","狗子" };
    // Use this for initialization
    void Start()
    {
        EventDispatcher.AddEventListener<int>(EventKeyTest.OnPlayerGoldChange, OnPlayerGoldValueChange);
        EventDispatcher.AddEventListener<string>(EventKeyTest.OnPlayerNameChage, OnPlayerNameChange);
    }

    void OnPlayerGoldValueChange(int gold)
    {
        goldText.text = gold.ToString();
    }
    void OnPlayerNameChange(string name)
    {
        playerNameText.text = name;
    }
    // Update is called once per frame
    void Update() {

    }
    private void OnDestroy()
    {
        EventDispatcher.RemoveEventListener<int>(EventKeyTest.OnPlayerGoldChange, OnPlayerGoldValueChange);
        EventDispatcher.RemoveEventListener<string>(EventKeyTest.OnPlayerNameChage, OnPlayerNameChange);
    }  
    //unityBtn事件
    public void OnClickToAddGold()
    {
        PlayerInfoManagerTest.Instance.PlayerGold += 100;
    }
    public void ClickReduceBtn() {
        PlayerInfoManagerTest.Instance.PlayerGold -= 50;
    }

    public void ClickChangeNameBtn() { 
        PlayerInfoManagerTest.Instance.PlayerName=names[Random.Range(0,names.Length)];
    }
}

5.創建需要註冊監聽玩家屬性改變的界面的腳本;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class TextPlayerGold : MonoBehaviour {

    // Use this for initialization
    void Start()
    {

        EventDispatcher.AddEventListener<int>(EventKeyTest.OnPlayerGoldChange, OnPlayerGoldChange);
    }

    private void OnPlayerGoldChange(int aaa)
    {
        gameObject.GetComponent<Text>().text = aaa.ToString();
    }
    // Update is called once per frame
    void Update () {
        
    }
}

完成.
