C#实验四停车场游戏的实现

停车场游戏的实现：

1.实验目的

掌握面向对象程序设计方法和Windows窗体应用程序设计方法。

2.实验内容

设计并实现一款停车场内车辆排位的游戏。停车场中有六个车位，每个车位的颜色都不一样。停车场中有五辆汽车，每辆汽车的颜色都与某一车位颜色相同，但五辆汽车颜色各不相同。玩家可以操纵汽车从当前车位沿设定的路径移动到空闲的车位。当每一辆车与所停车位颜色一致时，游戏成功。

3.实验要求

程序应具有较好的鲁棒性。
第一，要求使用面向对象程序设计方法进行设计。
第二，游戏操作应简单易行，用户体验良好。
第三，玩家移动车辆时，车辆不能移动到车位以外的位置。
第四，当玩家移动车辆不符合游戏规则时，应提示不能这样移动汽车。
第五，当所有汽车与所在车位颜色都一致时，应提示游戏成功，并能结束游戏。

创建Game类代码如下：

 class Game{public Space[] spaces;public Road[] roads;public Car[] cars;public int freeSpaceNum;public int df = 10;public Game(){spaces = new Space[6];roads = new Road[9];cars = new Car[5];spaces = new Space[6];roads = new Road[9];cars = new Car[5];spaces[0] = new Space(new Point(200, 400), Color.Blue);spaces[1] = new Space(new Point(200, 200), Color.Red);spaces[2] = new Space(new Point(500, 100), Color.Yellow);spaces[3] = new Space(new Point(800, 200), Color.Green);spaces[4] = new Space(new Point(800, 400), Color.Pink);spaces[5] = new Space(new Point(500, 500), Color.Black);roads[0] = new Road(0, 1, spaces[0].center, spaces[1].center);roads[1] = new Road(1, 2, spaces[1].center, spaces[2].center);roads[2] = new Road(2, 3, spaces[2].center, spaces[3].center);roads[3] = new Road(3, 4, spaces[3].center, spaces[4].center);roads[4] = new Road(4, 5, spaces[4].center, spaces[5].center);roads[5] = new Road(5, 0, spaces[5].center, spaces[0].center);roads[6] = new Road(0, 3, spaces[0].center, spaces[3].center);roads[7] = new Road(1, 4, spaces[1].center, spaces[4].center);roads[8] = new Road(2, 5, spaces[2].center, spaces[5].center);cars[0] = new Car(spaces[1].center, 1, Color.Blue);cars[1] = new Car(spaces[2].center, 2, Color.Red);cars[2] = new Car(spaces[3].center, 3, Color.Yellow);cars[3] = new Car(spaces[4].center, 4, Color.Green);cars[4] = new Car(spaces[0].center, 0, Color.Pink);freeSpaceNum = 5;}public void PaintParkingLot(Graphics g){foreach(Road r in roads){r.Paint(g);}foreach (Space s in spaces){s.Paint(g);}}public bool Success(){for (int i = 0; i < 5; i++){if (i!= cars[i].spaceNum){return false;}}return true;}public bool MoveCar(int carNum, int start, int end){foreach (Road r in roads){if (r.spaceStartNum == start && r.spaceEndNum == end){cars[carNum].Move(spaces[end].center, end);freeSpaceNum = start;return true;}if (r.spaceStartNum == end && r.spaceEndNum == start){cars[carNum].Move(spaces[end].center, end);freeSpaceNum = start;return true;}}return false;}}

创建Car类代码如下：

 class Car{public Point center;public int spaceNum;public Color color;public Car(Point center, int spaceNum, Color color){this.color = color;this.center = center;this.spaceNum = spaceNum;}public void Move(Point center, int spaceNum){this.center = center;this.spaceNum = spaceNum;}}

创建Space类代码如下：

class Space{public Point center;public const int radius = 50;public Color color;public Space(Point center, Color color){this.center = center;this.color = color;}public void Paint(Graphics g){SolidBrush brush = new SolidBrush(Color.Gray);g.FillRectangle(brush, center.X - radius, center.Y - radius, 2 * radius, 2 * radius);Pen pen = new Pen(color, 10);g.DrawRectangle(pen, center.X - radius, center.Y - radius, 2 * radius, 2 * radius);}}

创建Road类代码如下：

 class Road{public int spaceStartNum;public int spaceEndNum;Point start;Point end;static Color color = Color.DarkOrchid;public Road(int startNum, int endNum, Point p1, Point p2){spaceStartNum = startNum;spaceEndNum = endNum;start = p1;end = p2;}public void Paint(Graphics g){Pen pen = new Pen(color, 10);g.DrawLine(pen, start, end);}}

主窗体代码：

 public Form1(){InitializeComponent();game = new Game();for(int i=0;i<5;i++){string name = "pictureBox" + i.ToString();PictureBox pBox = (PictureBox)this.Controls.Find(name, false)[0];pBox.Location = new Point(game.cars[i].center.X - pBox.Width / 2, game.cars[i].center.Y - pBox.Height / 2);pBox.Visible = true;}}

在窗体中拉五个pictureBox控件代码分别为：

private void pictureBox0_Click(object sender, EventArgs e){PictureBox pBox = (PictureBox)sender;if (game.MoveCar(0,game.cars[0].spaceNum, game.freeSpaceNum)){pBox.Location = new Point(game.cars[0].center.X - pBox.Width / 2, game.cars[0].center.Y - pBox.Height / 2);if (game.Success()){MessageBox.Show("恭喜你！游戏通关了");}}else{MessageBox.Show("不能移动");}}

private void pictureBox1_Click(object sender, EventArgs e){PictureBox pBox = (PictureBox)sender;if (game.MoveCar(1, game.cars[1].spaceNum, game.freeSpaceNum)){pBox.Location = new Point(game.cars[1].center.X - pBox.Width / 2, game.cars[1].center.Y - pBox.Height / 2);if (game.Success()){MessageBox.Show("恭喜你！游戏通关了");}}else{MessageBox.Show("不能移动");}}

 private void pictureBox2_Click(object sender, EventArgs e){PictureBox pBox = (PictureBox)sender;if (game.MoveCar(2, game.cars[2].spaceNum, game.freeSpaceNum)){pBox.Location = new Point(game.cars[2].center.X - pBox.Width / 2, game.cars[2].center.Y - pBox.Height / 2);if (game.Success()){MessageBox.Show("恭喜你！游戏通关了");}}else{MessageBox.Show("不能移动");}}

 private void pictureBox3_Click(object sender, EventArgs e){PictureBox pBox = (PictureBox)sender;if (game.MoveCar(3, game.cars[3].spaceNum, game.freeSpaceNum)){pBox.Location = new Point(game.cars[3].center.X - pBox.Width / 2, game.cars[3].center.Y - pBox.Height / 2);if (game.Success()){MessageBox.Show("恭喜你！游戏通关了");}}else{MessageBox.Show("不能移动");}}

 private void pictureBox4_Click(object sender, EventArgs e){PictureBox pBox = (PictureBox)sender;if (game.MoveCar(4, game.cars[4].spaceNum, game.freeSpaceNum)){pBox.Location = new Point(game.cars[4].center.X - pBox.Width / 2, game.cars[4].center.Y - pBox.Height / 2);if (game.Success()){MessageBox.Show("恭喜你！游戏通关了");}}else{MessageBox.Show("不能移动");}}

pictureBox的图片可以自己换，方法如下：

button控件图片：

button控件（再玩一次）的代码如下：

private void button2_Click(object sender, EventArgs e){game = new Game();for (int i = 0; i < 5; i++){string name = "pictureBox" + i.ToString();PictureBox pBox = (PictureBox)this.Controls.Find(name, false)[0];pBox.Location = new Point(game.cars[i].center.X - pictureBox0.Width / 2, game.cars[i].center.Y - pictureBox0.Height / 2);pBox.Visible = true;}}

添加事件Form1_Paint如下：
代码如下：

private void Form1_Paint(object sender, PaintEventArgs e){game.PaintParkingLot(this.CreateGraphics());//画笔工具，把线路画出来}

4.实验测试计划

一、Space的生成和显示
1、测试程序是否能在游戏开始时，生成5个车位；
2、测试程序是否能在游戏开始时，显示5个车位。

二、Road的生成和显示
1、测试程序是否能在游戏开始时，生成X个通道，且通道首位分别连接两个车位；
2、测试程序是否能在游戏运行中，显示X个通道。

三、Car的生成、显示和移动
1、测试程序是否能在游戏开始时，生成X辆车，且每个车位都在一个车位内；
2、测试程序是否能在游戏开始时，将车沿着通道移动到空闲的车位上；
3、测试程序是否能在游戏开始时，出现车移动到车位以外的情况。
4、测试程序是否能在所有车都位于相同颜色的车位时，结束游戏。

5.实验测试结果

1、每一辆车都能移动到相邻的空车位；
2、如果没有相邻车位，车不能移动；
3、游戏成功显示游戏成功；
4、实现再来一次功能；
