新手學習c# 在博客園上看到后自己模仿打出來的第一個程序 開心，紀念一下
bean ：食物類
block ：蛇塊類
snake ：蛇類
Map ：地圖 圖形類
食物類：
class bean { private Point _origin;//用於畫食物頂端坐標 public Point Origin//封裝字段 { get { return _origin; } set { _origin = value; } } //顯示食物方法 public void showBean(Graphics g) { //定義紅色畫筆 SolidBrush brush = new SolidBrush(Color.Red); //用實心矩形畫食物 g.FillRectangle(brush, _origin.X, _origin.Y, 15, 15); } //食物消失方法 public void unShowBean(Graphics g) { //定義背景色畫筆 SolidBrush brush = new SolidBrush(Color.Red); //用實心矩形畫食物 g.FillRectangle(brush, _origin.X, _origin.Y, 15, 15); } }
蛇塊類：2020-02-16
public class block { //是否是蛇頭 private bool _isHead; public bool IShead { get { return _isHead; } set { _isHead = value; } } //蛇塊編號 private int _blockNumber; public int BlockNumber { get { return _blockNumber; } set { _blockNumber = value; } } //蛇塊在左上角的位置 private Point _origin; public Point Origin { get { return _origin; } set { _origin = value; } } //根據指定位置畫蛇塊 public void showBlock(Graphics g) { Bitmap bitMap; if (IShead) { bitMap = new Bitmap(Image.FromFile("blue.gif")); } else { bitMap = new Bitmap(Image.FromFile("Yellow.gif")); } g.DrawImage(bitMap, Origin.X, Origin.Y, 15, 15); } //蛇塊消除 public void UnShowBlock(Graphics g) { SolidBrush brush = new SolidBrush(Color.Silver); g.FillRectangle(brush,Origin.X,Origin.Y,15,15); } }
蛇類：
public class Snake { //用於存放蛇的集合 private List<block> blockList; //0-1-2-3 上-右-下-左 private int direction = 1; //蛇運動方向屬性 public int Direction { get { return direction; } set { direction = value; } } //蛇右的編號 蛇頭的長度 private int headNumber; //蛇頭左上角坐標 private Point headPoint; //蛇頭坐標只讀屬性 public Point HeadPoint { get { return headPoint; } } private Point mapLeft; //游戲開始時初始的蛇 public Snake(Point map, int count)//填充Blocklist { mapLeft = map; block blockSnake; //定義蛇的起始位置 Point p = new Point(map.X + 15, map.Y + 15); blockList = new List<block>(); //循環畫蛇 用於填充集合 for (int i = 0; i < count; i++) { //X坐標加15 p.X += 15; //實例化蛇塊 blockSnake = new block(); //定義蛇塊左上角的位置 blockSnake.Origin = p; //定義蛇塊編號1,2,3,4 blockSnake.BlockNumber = i + 1; if (i == count - 1) { //蛇頭 headPoint = blockSnake.Origin; //給蛇頭賦值 blockSnake.IShead = true; } blockList.Add(blockSnake); } } //蛇邊長函數 public void snakeGrowth() { //找到蛇頭坐標 Point head = blockList[blockList.Count - 1].Origin; int x = head.X; int y = head.Y; switch (direction) { case 0: y = y - 15; break; case 1: x = x + 15; break; case 2: y = y + 15; break; case 3: x = x - 15; break; } //先把原先蛇塊變為普通蛇塊 blockList[blockList.Count - 1].IShead = false; //實例化新蛇頭 block headNew = new block(); headNew.IShead = true; headNew.BlockNumber = blockList.Count + 1; headNew.Origin = new Point(x, y); blockList.Add(headNew); headNumber++; headPoint = headNew.Origin; } //蛇先前運動 沒有吃到食物 public void Go(Graphics g) { block snakeTail = blockList[0]; //消除蛇塊 snakeTail.UnShowBlock(g); //集合中移除尾巴 blockList.RemoveAt(0); //序號全部減1 foreach (var item in blockList) { item.BlockNumber--; } headNumber--; snakeGrowth(); } //蛇的方向轉換 public void turnDriction(int pDriction) { switch (direction) { //原來向上運動 case 0: { //希望想做運動 if (pDriction == 3) direction = 3; else if (pDriction == 1) direction = 1; } break; case 1: { if (pDriction == 2) direction = 2; else if (pDriction == 0) direction = 0; break; } case 2: { if (pDriction == 1) direction = 1; else if (pDriction == 3) direction = 3; break; } case 3: { if (pDriction == 0) direction = 0; else if (pDriction == 2) direction = 2; break; } } } //蛇顯示函數 public void ShowSnake(Graphics g) { foreach (var item in blockList) { item.showBlock(g); } } //隱藏蛇 public void unShowSnake(Graphics g) { foreach (var item in blockList) { item.UnShowBlock(g); } } //自己是否會碰到自己 public bool IsTouchMyself() { bool isTouch = false; for (int i = 0; i < blockList.Count - 1; i++) { if (headPoint == blockList[i].Origin) { isTouch = true; break; } } return isTouch; } //重置蛇 public void Reset(Point Map, int count) { block blockSnake; //定義蛇的起始位置 Point p = new Point(mapLeft.X + 15, mapLeft.Y + 15); blockList = new List<block>(); //循環畫蛇塊用於填充集合 for (int i = 0; i < count; i++) { //x坐標加15 p.X += 15; //實例化蛇塊 blockSnake = new block(); //定義蛇塊左上角位置 blockSnake.Origin = p; //定義蛇塊編號 blockSnake.BlockNumber = i + 1; if (i == count - 1) { //蛇頭 //給蛇頭位置賦值 headPoint = blockSnake.Origin; blockSnake.IShead = true; } blockList.Add(blockSnake); } } }
地圖類：
public class Map { private Point mapLeft; private static int unit = 15; //定義地圖長度為28個蛇塊 private readonly int length = 30 * unit; //定義地圖寬度為20個蛇塊 private readonly int width = 25 * unit; //定義分數 public int score = 0; //定義蛇 private readonly Snake snake; public bool victory = false; public Snake Snake { get { return snake; } } bean food; public Map(Point start) { //把地圖左上角的點賦值給全局變量 mapLeft = start; //實例化蛇 snake = new Snake(start, 5); //實例化食物 food = new bean(); food.Origin = new Point(start.X + 30, start.Y + 30); } //產生一個新食物 private bean foodRandom() { Random d = new Random(); int x = d.Next(0, length / unit); int y = d.Next(0, width / unit); Point Origin = new Point(mapLeft.X+x*15,mapLeft.Y+y*15); bean food = new bean(); food.Origin = Origin; return food; } //顯示新食物方法 public void showNewFood(Graphics g) { //消除原先食物 food.unShowBean(g); //產生隨機位置的食物 food = foodRandom(); //顯示新食物 food.showBean(g); } //畫地圖 public void showMap(Graphics g) { //創建一支紅筆 Pen pen = new Pen(Color.Blue); //畫地圖框 g.DrawRectangle(pen, mapLeft.X, mapLeft.Y, length, width); //顯示食物 food.showBean(g); if (cheakBean()) { //吃到了食物 //顯示新食物 showNewFood(g); //蛇變長 snake.snakeGrowth(); //加分 score += 10; //顯示蛇 snake.ShowSnake(g); } else { snake.Go(g); snake.ShowSnake(g); } } //判斷是否吃到食物 public bool cheakBean() { return food.Origin.Equals(snake.HeadPoint); } //檢查蛇是否撞牆 public bool checkSnake() { return !(Snake.HeadPoint.X > mapLeft.X - 5 && Snake.HeadPoint.X < (mapLeft.X + length - 5) && Snake.HeadPoint.Y > mapLeft.Y - 5 && Snake.HeadPoint.Y < (mapLeft.Y + width - 5)); } //重新開始 public void Resect(Graphics g) { Snake.unShowSnake(g); Snake.Reset(mapLeft,5); } }
窗體代碼：
public partial class Form1 : Form { public Form1() { InitializeComponent(); //定義地圖 map = new Map(new Point(50, 50)); this.BackColor = Color.Silver; } private readonly Map map; private int gradeNum = 100; private int pink; private void timer1_Tick(object sender, EventArgs e) { this.開始游戲ToolStripMenuItem.Text = "重新開始"; this.label1.Text = map.score.ToString(); if (map.score > 500) { this.timer1.Enabled = false; MessageBox.Show("通關"); } Bitmap bmp =new Bitmap(this .Width,this.Height); BackgroundImage = bmp; Graphics g = Graphics.FromImage(bmp); map.showMap(g); if (map.checkSnake() || map.Snake.IsTouchMyself()) { this.timer1.Enabled = false; MessageBox.Show("失敗"); } } private void Form1_Load(object sender, EventArgs e) { SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true); UpdateStyles(); } private void Form1_KeyDown(object sender, KeyEventArgs e) { int k, d = 0; k = e.KeyValue; if (k == 37) { d = 3; } if (k == 40) { d = 2; } if (k == 38) { d = 0; } if (k == 39) { d = 1; } map.Snake.turnDriction(d); } private void 開始游戲ToolStripMenuItem_Click(object sender, EventArgs e) { if (this.label2.Text == "") { MessageBox.Show("請選擇級別"); return; } if(this .開始游戲ToolStripMenuItem.Text =="開始") { this.開始游戲ToolStripMenuItem.Text = "重新開始"; timer1.Enabled = true; } else if(this .開始游戲ToolStripMenuItem.Text=="重新開始") { this.開始游戲ToolStripMenuItem.Text = "開始"; this.繼續ToolStripMenuItem.Text = "暫停"; this.timer1.Enabled = true; map.Resect(CreateGraphics()); map.score = 0; } } private void 繼續ToolStripMenuItem_Click(object sender, EventArgs e) { if (this.繼續ToolStripMenuItem.Text == "暫停") { this.繼續ToolStripMenuItem.Text = "繼續"; this.timer1.Enabled = true; } else if (this.繼續ToolStripMenuItem.Text == "繼續") { this.繼續ToolStripMenuItem.Text = "暫停"; this.timer1.Enabled = false; } } private void 低級ToolStripMenuItem_Click(object sender, EventArgs e) { gradeNum = 200; this.label2.Text = "菜鳥"; this.timer1.Interval = gradeNum; } private void 中級ToolStripMenuItem_Click(object sender, EventArgs e) { gradeNum = 150; this.label2.Text = "平民"; this.timer1.Interval = gradeNum; } private void 高級ToolStripMenuItem_Click(object sender, EventArgs e) { gradeNum = 100; this.label2.Text = "高手"; this.timer1.Interval = gradeNum; } private void 大神ToolStripMenuItem_Click(object sender, EventArgs e) { gradeNum = 50; this.label2.Text = "大神"; this.timer1.Interval = gradeNum; } }
不是自己想的 但是我弄懂了
