游戏介绍

三个牧师与三个魔鬼想要过河，但是一条船只能同时坐两个人，并且如果一边岸上的魔鬼数量大于牧师（船上的牧师或者魔鬼不算在岸上），那么牧师就会被魔鬼杀死，游戏结束。要想所有人都安全过河，该怎么办呢？

Priests and Devils is a puzzle game in which you will help the Priests and Devils to cross the river within the time limit. There are 3 priests and 3 devils at one side of the river. They all want to get to the other side of this river, but there is only one boat and this boat can only carry two persons each time. And there must be one person steering the boat from one side to the other side. In the flash game, you can click on them to move them and click the go button to move the boat to the other direction. If the priests are out numbered by the devils on either side of the river, they get killed and the game is over. You can try it in many > ways. Keep all priests alive! Good luck!

游戏实现框架

玩家行为

效果

条件

点击角色

（牧师/魔鬼）

上船/下船

上船时船上须有空位，船靠近相应的岸边

点击船

船移动到对岸

船上至少有一个角色(船不能为空）

依然采用MVC框架

model模型包括船boat，角色role（牧师和魔鬼），河岸bank，移动move（用于控制角色和船的运动）

view视图则有GUI，显示游戏失败或者胜利的字样。

controller控制器有boatCtrl，roleCtrl，bankCtrl，moveCtrl，FirstController，SSDirector等。

其中，最关键的是FirstController

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

public class FirstController : MonoBehaviour, ISceneController, IUserAction {
    ShoreCtrl leftShoreController, rightShoreController;
    River river;
    BoatCtrl boatController;
    RoleCtrl[] roleControllers;
    MoveCtrl moveController;
    bool isRunning;
    float time;

    public void LoadResources() {
        //role
        roleControllers = new RoleCtrl[6];
        for (int i = 0; i < 6; ++i) {
            roleControllers[i] = new RoleCtrl();
            roleControllers[i].CreateRole(Position.role_shore[i], i < 3 ? true : false, i);
        }

        //shore
        leftShoreController = new ShoreCtrl();
        leftShoreController.CreateShore(Position.left_shore);
        leftShoreController.GetShore().shore.name = "left_shore";
        rightShoreController = new ShoreCtrl();
        rightShoreController.CreateShore(Position.right_shore);
        rightShoreController.GetShore().shore.name = "right_shore";

        //将人物添加并定位至左岸  
        foreach (RoleCtrl roleController in roleControllers)
        {
            roleController.GetRoleModel().role.transform.localPosition = leftShoreController.AddRole(roleController.GetRoleModel());
        }
        //boat
        boatController = new BoatCtrl();
        boatController.CreateBoat(Position.left_boat);

        //river
        river = new River(Position.river);

        //move
        moveController = new MoveCtrl();

        isRunning = true;
        time = 60;


    }

    public void MoveBoat() {
        if (isRunning == false || moveController.GetIsMoving()) return;
        if (boatController.GetBoatModel().isRight) {
            moveController.SetMove(Position.left_boat, boatController.GetBoatModel().boat);
        }
        else {
            moveController.SetMove(Position.right_boat, boatController.GetBoatModel().boat);
        }
        boatController.GetBoatModel().isRight = !boatController.GetBoatModel().isRight;
    }

    public void MoveRole(Role roleModel) {
        if (isRunning == false || moveController.GetIsMoving()) return;
        if (roleModel.inBoat) {
            if (boatController.GetBoatModel().isRight) {
                moveController.SetMove(rightShoreController.AddRole(roleModel), roleModel.role);
            }
            else {
                moveController.SetMove(leftShoreController.AddRole(roleModel), roleModel.role);
            }
            roleModel.onRight = boatController.GetBoatModel().isRight;
            boatController.RemoveRole(roleModel);
        }
        else {
            if (boatController.GetBoatModel().isRight == roleModel.onRight) {
                if (roleModel.onRight) {
                    rightShoreController.RemoveRole(roleModel);
                }
                else {
                    leftShoreController.RemoveRole(roleModel);
                }
                moveController.SetMove(boatController.AddRole(roleModel), roleModel.role);
            }
        }
    }

    public void Check() {
        if (isRunning == false) return;
        this.gameObject.GetComponent<UserGUI>().gameMessage = "";
        if (rightShoreController.GetShore().priestCount == 3) {
            this.gameObject.GetComponent<UserGUI>().gameMessage = "You Win!";
            isRunning = false;
        }
        else {
            int leftPriestCount, rightPriestCount, leftDevilCount, rightDevilCount;
            leftPriestCount = leftShoreController.GetShore().priestCount ;
            rightPriestCount = rightShoreController.GetShore().priestCount;
            leftDevilCount = leftShoreController.GetShore().devilCount ;
            rightDevilCount = rightShoreController.GetShore().devilCount;
            if (leftPriestCount != 0 && leftPriestCount < leftDevilCount || rightPriestCount != 0 && rightPriestCount < rightDevilCount) {
                this.gameObject.GetComponent<UserGUI>().gameMessage = "Game Over!";
                isRunning = false;
            }
        }
    }

    void Awake() {
        SSDirector.GetInstance().CurrentSceneController = this;
        LoadResources();
        this.gameObject.AddComponent<UserGUI>();
    }

    void Update() {
        if (isRunning) {
            time -= Time.deltaTime;
            this.gameObject.GetComponent<UserGUI>().time = (int)time;
            if (time <= 0) {
                this.gameObject.GetComponent<UserGUI>().time = 0;
                this.gameObject.GetComponent<UserGUI>().gameMessage = "Game Over!";
                isRunning = false;
            }
        }
    }
}

这段代码实现了ISceneController和IUserAction两个接口，其中ISceneController是游戏场景控制器需要实现的接口，IUserAction是用户交互操作需要实现的接口。

该控制器包含了以下功能：
