3D遊戲編程與設計 Week8

這次的作業是跟着這位師兄：@MokHoYin來做的，加上了自己的一些理解，師兄博客地址：http://blog.csdn.net/qq_33000225/article/details/70045292

我就直接貼代碼了，不過有點長-_-

1.GameEventManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Com.Patrols;

public class GameEventManager : MonoBehaviour {
    public delegate void GameScoreAction();
    public static event GameScoreAction myGameScoreAction;

    public delegate void GameOverAction();
    public static event GameOverAction myGameOverAction;

    private SceneController scene;

    void Start () {
        scene = SceneController.getInstance();
        scene.setGameEventManager(this);
    }
	
	void Update () {
		
	}

    //hero逃離巡邏兵，得分
    public void heroEscapeAndScore() {
        if (myGameScoreAction != null)
            myGameScoreAction();
    }

    //巡邏兵捕獲hero，遊戲結束
    public void patrolHitHeroAndGameover() {
        if (myGameOverAction != null)
            myGameOverAction();
    }
}

        detectKeyInput();
    }
