C#編程 [“貪吃蛇”小游戲]

1、C#編程 “貪吃蛇”小游戲一、項目內(nèi)容及要求編程實現(xiàn)一個“貪吃蛇”小游戲，具體要求如下：1）程序啟動后，蛇身默認(rèn)向右移動，直到用戶按下方向鍵改變運動方向。2）玩家通過鍵盤上的上、下、左、右四個方向鍵控制蛇在地圖上尋找豆，蛇吃下豆后，蛇身加長一節(jié)。 3）界面上任意時刻同時會有三個豆，豆的位置隨機生成，定時刷新。4）在游戲過程中，若蛇頭碰到場地邊界或自己的身體，則游戲失敗。二、算法分析一、控件設(shè)計1）主菜單控件 MenuStrip2）面板控件 Panel：背景色為黃色3）標(biāo)簽控件 Label1、Label2 二、類設(shè)計1）Game類，入口主窗體、游戲界面類。Game類的主要功能包括控制游戲的開始與

2、暫停、選擇游戲關(guān)卡、聲明并創(chuàng)建蛇的行為及豆的行為線程，啟動線程。2）Block類：代表蛇和豆一個節(jié)點的塊類，游戲中需要繪制的塊分為以下三種情況：（1）蛇頭：紅色橢圓（2）蛇身：紅色矩形 （3）豆：綠色橢圓添加類的屬性：塊的顏色、是否蛇頭、是否豆，橫坐標(biāo)X、縱坐標(biāo)Y添加類的行為：繪制塊draw（）方法，構(gòu)造函數(shù)（判斷是否豆），重載構(gòu)造函數(shù)3）Snake類：定義游戲中的蛇。其屬性包括蛇移動的方向以及蛇身的集合（泛型集合List<>）；其行為成員包括蛇吃豆、吃過豆之后蛇身增長、蛇身移動以及判斷蛇是否死亡等。4）Beans類：定義游戲中的豆。其屬性包括3個豆組成的列表（List<&g

3、t;）；其行為成員包括定時刷新豆的集合以及移除某個豆。三、界面及運行過程四、關(guān)鍵代碼（代碼要求注釋完整，例如：變量的作用，語句的作用，方法的功能等都要加注釋說明）namespace 項目5 public partial class Form1 : Form Food food = new Food(); Snake snake = new Snake(); private int score; public Form1() InitializeComponent(); timer1.Enabled = false;/timer是否可用 timer1.Interval = snake.Speed
