前言

貪吃蛇游戲是一個(gè)耳熟能詳?shù)男∮螒?本次我們講解他的簡(jiǎn)單的實(shí)現(xiàn),需要掌握基本的API知識(shí)(http://t.csdnimg.cn/uHH6y),簡(jiǎn)單的C語(yǔ)言知識(shí)和基本的數(shù)據(jù)結(jié)構(gòu)鏈表

蛇的節(jié)點(diǎn)

在游戲運(yùn)?的過(guò)程中，蛇每次吃?個(gè)?物，蛇的?體就會(huì)變??節(jié)，如果我們使?鏈表存儲(chǔ)蛇的信 息，那么蛇的每?節(jié)其實(shí)就是鏈表的每個(gè)節(jié)點(diǎn)。每個(gè)節(jié)點(diǎn)只要記錄好蛇?節(jié)點(diǎn)在地圖上的坐標(biāo)就?， 所以蛇節(jié)點(diǎn)結(jié)構(gòu)如下：

typedef struct SnakeNode

{

int x;

int y;

struct SnakeNode* next;

}SnakeNode, * pSnakeNode;

但是這樣不好維護(hù)這一條蛇,要管理整條貪吃蛇，我們?cè)俜庋b?個(gè)Snake的結(jié)構(gòu)來(lái)維護(hù)整條貪吃蛇

typedef struct Snake

{

pSnakeNode _pSnake;維護(hù)整條蛇的指針

pSnakeNode _pFood;維護(hù)?物的指針

enum DIRECTION _Dir;頭的?向默認(rèn)是向右

enum GAME_STATUS _Status;游戲狀態(tài)

int _Socre;當(dāng)前獲得分?jǐn)?shù)

int _Add;默認(rèn)每個(gè)?物10分

int _SleepTime;每??步休眠時(shí)間

}Snake, * pSnake;

開(kāi)始前?void GameStart(pSnake ps)

游戲開(kāi)始,先打印蛇的身體和地圖,以及一些幫助的提示語(yǔ)句,先完成一些準(zhǔn)備工作

void GameStart(pSnake ps)

{

設(shè)置控制臺(tái)窗?的??，30?，100列

//mode 為DOS命令

system("mode con cols=100 lines=30");

//設(shè)置cmd窗?名稱

system("title 貪吃蛇");

//獲取標(biāo)準(zhǔn)輸出的句柄(?來(lái)標(biāo)識(shí)不同設(shè)備的數(shù)值)

HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE); //影藏光標(biāo)操作

CONSOLE_CURSOR_INFO CursorInfo; //打印歡迎界?

WelcomeToGame(); //打印地圖

CreateMap(); //初始化蛇

GetConsoleCursorInfo(hOutput, &CursorInfo);//獲取控制臺(tái)光標(biāo)信息

CursorInfo.bVisible = false; //隱藏控制臺(tái)光標(biāo)

SetConsoleCursorInfo(hOutput, &CursorInfo);//設(shè)置控制臺(tái)光標(biāo)狀態(tài)

InitSnake(ps);

//創(chuàng)造第?個(gè)?物

CreateFood(ps);

}

void WelcomeToGame()

在游戲正式開(kāi)始之前，做?些功能提醒,來(lái)讓玩家了解游戲方法與規(guī)則,其中SetPos是一個(gè)已經(jīng)封裝后的函數(shù),可以把這個(gè)字體打在這個(gè)坐標(biāo)

void WelcomeToGame()

{

SetPos(40, 15);

printf("歡迎來(lái)到貪吃蛇?游戲");

SetPos(40, 25);//讓按任意鍵繼續(xù)的出現(xiàn)的位置好看點(diǎn)

system("pause");

system("cls");

SetPos(25, 12);

printf("? ↑ . ↓ . ← . → 分別控制蛇的移動(dòng)， F3為加速，F(xiàn)4為減速\n");

SetPos(25, 13);

}

void CreateMap()

創(chuàng)建地圖就是將強(qiáng)打印出來(lái)，因?yàn)槭菍捵址蛴。惺?wprintf函數(shù)，打印格式串前使?L 打印地圖的關(guān)鍵是要算好坐標(biāo)，才能在想要的位置打印墻體。

{

SetPos(0, 0);

} //左//x是0，y從1開(kāi)始增?
