lab05：Preists and Devils 牧师与魔鬼游戏

游戏简介

《牧师与魔鬼》是一款益智游戏，目标是帮助三个牧师和三个魔鬼在规定时间内安全过河。游戏中只有一艘船，每次只能容纳两个人，而且船的移动必须由一个人完成。需要注意的是，如果河岸上的牧师人数多于魔鬼，魔鬼会被牧师杀死，导致游戏失败。因此，在游戏中需要运用策略，巧妙地安排牧师和魔鬼的上下船顺序，以确保所有牧师都能够安全过河。

Objects

• 河岸地形×2，
• 河流地形
• 船对象
• 牧师对象x3
• 魔鬼对象x3

玩家动作表

MVC结构组织

• Model：存储数据对象，以及基本的对数据操作的方法
• Controller：接受用户事件，操作Model数据
• View：视图模型，将事件转发到Controller

制作预制prefabs

在这里采用了一些免费的unity素材，大家可以到assests store下载免费的资源

• 魔鬼和牧师
  
• 船只
  
• 河岸
  
• 河流
  
  另外我还添加了一个天空盒挂载在摄像机上
  

制作完成后将他们拖入Assets中成为预制

程序UML图

这里我们使用的是umlet这个工具
当然staruml之类的工具都可以

MODELS

在这里每类只放出代表性的几个类，不然文章太长
├─Models

│ Boat.cs 定义了船模型，挂载了click组件
│ Click.cs 定义了点击模型，重载了monobehavior里的点击事件函数
│ DefaultPosition.cs 存储了一些static的预设位置信息
│ Land.cs 定义了河岸模型
│ Move.cs 定义了移动gameobject的模型
│ River.cs 定义了河流模型
│ Role.cs 定义了人物模型

using System.Collections;
using System.Collections.Generic;
using UnityEngine;// 船只模型
public class Boat
{//船对象public GameObject boat;//关联船上人员public Role[] roles;public bool isRight;public int priestCount, devilCount;public Boat(Vector3 position){// 载入船预制件boat = GameObject.Instantiate(Resources.Load("Prefabs/Boat", typeof(GameObject))) as GameObject;// 设置属性boat.name = "boat";boat.transform.position = position;boat.transform.localScale = new Vector3(2.8f, 0.4f, 2);// 人员对象创建roles = new Role[2];isRight = false;priestCount = devilCount = 0;// 添加碰撞盒与点击组件boat.AddComponent<BoxCollider>();boat.AddComponent<Click>();}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Move : MonoBehaviour
{public bool isMoving = false;public float speed = 5;// 需要经过的轨迹点public Vector3 destination;public Vector3 mid_destination;// Update is called once per framevoid Update(){// 已到达终点 do nothingif (transform.localPosition == destination){isMoving = false;return;}// else movingelse if (transform.localPosition.x != destination.x && transform.localPosition.y != destination.y){transform.localPosition = Vector3.MoveTowards(transform.localPosition, mid_destination, speed * Time.deltaTime);}else{transform.localPosition = Vector3.MoveTowards(transform.localPosition, destination, speed * Time.deltaTime);}isMoving = true;}
}

VIEWS

─Views

UserGUI.cs 视图类

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class UserGUI : MonoBehaviour
{// 用户动作接口实例IUserAction userAction;public string message;GUIStyle msgStyle, titleStyle;bool isGameEnd;public void SetMessage(string msg) { message = msg; }void Start(){// 侧向转型实例化用户动作对象userAction = SSDirector.GetInstance().CurrentSceneController as IUserAction;// 设置一些stylemsgStyle = new GUIStyle();msgStyle.normal.textColor = Color.red;msgStyle.fontSize = 40;titleStyle = new GUIStyle();titleStyle.normal.textColor = Color.white;titleStyle.fontSize = 50;isGameEnd = false;}void OnGUI(){// 检查游戏是否结束isGameEnd = userAction.Check();// 设置游戏标题GUI.Label(new Rect(Screen.width * 0.3f, Screen.height * 0.1f, 50, 200), "Preists and Devils", titleStyle);// 设置游戏的提示信息GUI.Label(new Rect(Screen.width * 0.4f, 150, 50, 200), message, msgStyle);// 重新开始if (isGameEnd && GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.5f, 100, 50), "Restart")){Restart();}}void Restart(){userAction.Restart();}
}

CONTROLLERS

─Controllers

│ BoatController.cs 船控制相关的控制器
│ FirstController.cs 场记，控制对象的加载与总控其他控制器
│ IClickAction.cs 接口，定义了一个点击动作接口
│ ISceneController.cs 接口，控制布景、演员的上下场、管理动作等执行
│ IUserAction.cs 接口，定义了玩家的操作
│ LandController.cs 陆地相关控制器
│ MoveController.cs 移动相关控制器
│ RoleController.cs 人物相关控制器
│ SSDirector.cs 总导演，关联ISceneController的一个对象
