首先先建立3个文件。
Snake.h 函数的声明
Snake.c 函数的定义
Test.c 贪吃蛇的测试
我们分析这整个项目
首先在我们实现游戏开始的部分之前,我们要先创建贪吃蛇的节点,再由此创建整个贪吃蛇所包含的一些信息:
#pragma once
//蛇身节点
typedef struct SnakeNode
{
int x;
int y;
struct SnakeNode* next;
}SnakeNode,* pSnakeNode;
//SnakeNode 是struct SnakeNode的重命名
//pSnakeNode 是struct SnakeNode *的重命名
//我们再根据此来创建整条蛇
typedef struct Snake
{
pSnakeNode pSnake;//维护整条蛇的指针
pSnakeNode pFood; //维护食物的指针
int score;//当前的分数
int foodWeight;//食物的权重
int SleepTime;//休眠时间(其实就是你肉眼能看到的一眨一眨的)
enum DIRECTION Dir;//蛇重生默认方向
enum GAMESTATUS Status;//游戏状态
}Snake,*pSnake;
我们枚举一下这个贪吃蛇中所有的一些状态:
//方向
enum DIRECTION
{
UP=1,
DOWN,
LEFT,
RIGHT
};
//游戏状态
enum GAME_STATUS
{
OK=1,//正常运行
ESC, //按了ESC键退出,正常退出
KILL_BY_WALL,//撞墙
KILL_BY_SELF //撞到自身
};
然后我们就能书写测试函数中的内容了
根据这张图来写
#define _CRT_SECURE_NO_WARNINGS 1
#include "Snake.h"
#include
void test()
{
int ch=0;
srand((unsigned int)time(NULL));
do
{
//先创建一条贪吃蛇(不是物理上的,是物理上乃至整个游戏的地基)
Snake snake = { 0 };
//GameStart(&snake);//游戏开始
//GameRun(&snake);//游戏中
//GameEnd(&snake);//游戏结束
SetPos(20, 15);
printf("本局结束,是否再来一局?(Y/N)--");
ch = getchar();
getchar();
} while (ch == 'Y' || ch == 'y');
SetPos(0, 27);//打印程序退出以及代码所在文件地址,这里设置一下是为了美观
}
int main()
{
//修改当前地区模式,支持中文地区的打印
setlocale(LC_ALL, "");
//测试贪吃蛇
test();
return 0;
1.其中的SetPos:封装⼀个设置光标位置的函数,他的头文件为#include
//设置光标的坐标
void SetPos(short x, short y)
{
COORD pos = { x,y };
HANDLE hOutput = NULL;
//获取标准输出的句柄(⽤来标识不同设备的数值)
hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
//设置标准输出上光标的位置为pos
SetConsoleCursorPosition(hOutput, pos);
}
2.其中的setlocale为:
提供的函数⽤于控制C标准库中对于不同的地区会产⽣不⼀样⾏为的部分。 setlocale 函数⽤于修改当前地区,可以针对⼀个类项修改,也可以针对所有类项。setlocale 的第⼀个参数可以是前⾯说明的类项中的⼀个,那么每次只会影响⼀个类项,如果第⼀个参 数是LC_ALL,就会影响所有的类项。C标准给第⼆个参数仅定义了2种可能取值:"C"和" "。当地区设置为"C"时,库函数按正常⽅式执⾏,⼩数点是⼀个点。当程序运⾏起来后想改变地区,就只能显⽰调⽤setlocale函数。⽤" "作为第2个参数,调⽤setlocale 函数就可以切换到本地模式,这种模式下程序会适应本地环境。⽐如:切换到我们的本地模式后就⽀ 持宽字符(汉字)的输出等。
接下来我们实现GameStart函数
void GameStart(pSnake ps)
{
//设置控制台窗口的大小,50行,150列
system("mode con cols=150 lines=50");
//设置窗口名称
system("title 贪吃蛇大作战");
//获取标准输出的句柄(⽤来标识不同设备的数值)
HANDLE hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
//隐藏光标操作
CONSOLE_CURSOR_INFO CursorInfo;
GetConsoleCursorInfo(hOutput, &CursorInfo);//获取控制台光标信息
CursorInfo.bVisible = false; //隐藏控制台光标
SetConsoleCursorInfo(hOutput, &CursorInfo);//设置控制台光标状态
//打印欢迎界面
WelcomTOGame();
//打印地图
CreateMap();
//初始化蛇
InitSnkae(ps);
//创造第一个食物
CreateFood(ps);
}
我们再实现GameStart的
//打印欢迎界面
WelcomTOGame();
//打印地图
CreateMap();
//初始化蛇
InitSnkae(ps);
//创造第一个食物
CreateFood(ps);
void WelcomTOGame()
{
SetPos(80, 30);
printf("欢迎来到贪吃蛇大作战");
SetPos(80, 50);
system("pause");
system("cls");
SetPos(50, 25);
printf("⽤ ↑.↓.←.→ 分别控制蛇的移动, F1为加速,F2为减速\n");
SetPos(50, 26);
printf("加速是给勇士的奖励.");
SetPos(40, 25);
system("pause");
system("cls");
getchar();//此时加一个getchar()是为了让他在这里停下,否则我们看不到这个过程,只是为了更
//好的测试
}
我们这时候运行一下程序看下结果
这里的 ↑.↓.←.→是用的搜狗输入法符号大全里的
void CreateMap()
{
int i = 0;
//上下左右
SetPos(0, 0);
for (i = 0; i < 114; i += 2)
{
wprintf(L"%c", WALL);
}
SetPos(0, 52);
for (i = 0; i < 114; i += 2)
{
wprintf(L"%c", WALL);
}
for(i = 1; i < 52; i++)
{
SetPos(0, i);
wprintf(L"%c", WALL);
}
for (i = 1; i < 52; i++)
{
SetPos(112, i);
wprintf(L"%c", WALL);
}
//打印提⽰信息
SetPos(128, 30);
printf("不能穿墙,不能咬自己\n");
SetPos(128, 32);
printf("利用↑.↓.←.→分别控制蛇的移动.");
SetPos(128, 34);
printf("F1 为加速,F2 为减速\n");
SetPos(128, 36);
printf("ESC :退出游戏.space:暂停游戏.");
SetPos(128, 40);
printf("@你小子别偷懒了");
}
这里的WALL在.h文件中用宏定义说明一下
#define WALL L'◇'
这个时候我们再次运行一次代码
跟上次不同的是:这次多了一个规则的地图
void InitSnake(pSnake ps)
{
//创建一个单独的节点,这是为了创建蛇的身体
pSnakeNode cur = NULL;
int i = 0;
//创建蛇身节点,并初始化坐标,利用头插法
for (i = 0; i < 5; i++)
{
cur = (pSnakeNode)malloc(sizeof(SnakeNode));
if (cur == NULL)
{
perror("malloc fail");
return;
}
//如果cur不为空,就设置坐标
cur->next = NULL;
cur->x = POS_X + i * 2;
cur->y = POS_Y;
//然后给本游戏的蛇进行设置
if (ps->pSnake == NULL)
{
ps->pSnake = cur;
}
else
{
cur->next = ps->pSnake;
ps->pSnake = cur;
}
}
//打印蛇
cur = ps->pSnake;
while (cur)
{
SetPos(cur->x, cur->y);
wprintf(L"%c", BODY);
cur = cur->next;
}
ps->SleepTime = 200;
ps->score = 0;
ps->status = OK;
ps->dir = RIGHT;
ps->foodWeight = 10;
getchar();
}
我们再次运行:此时就有蛇的存在了
到这里我们还差创建食物
void CreateFood(pSnake ps)
{
int x = 0;
int y = 0;
again:
//x坐标为2的倍数,如果他一直不为2的倍数就一直算
do
{
x = rand() % 109 + 2;
y = rand() % 52 + 1;
} while (x % 2 != 0);
pSnakeNode cur = ps->pSnake;//获取指向蛇头的指针
//食物不能和蛇身冲突
while (cur)
{
if (cur->x == x && cur->y == y)
{
goto again;
}
cur = cur->next;
}
pSnakeNode pFood = (pSnakeNode)malloc(sizeof(SnakeNode));//创建食物
if (pFood == NULL)
{
perror("malloc fail");
return;
}
pFood->x = x;
pFood->y = y;
ps->pFood = pFood;
SetPos(x, y);
wprintf(L"%lc", FOOD);
}
这个时候我们再次运行代码
食物出现了,也就是说我们游戏开始的过程完成了,接下来就是游戏中的代码了。
void GameRun(pSnake ps)
{
do
{
//当前的分数情况
SetPos(124, 20);
printf("总分:%5d\n", ps->score);
SetPos(124, 22);
printf("食物的分值:%02d\n", ps->FoodWeight);
//检测按键
//上、下、左、右、ESC、空格、F1、F2
if (KEY_PRESS(VK_UP) && ps->dir != DOWN)
{
ps->dir = UP;
}
else if (KEY_PRESS(VK_DOWN) && ps->dir != UP)
{
ps->dir = DOWN;
}
else if (KEY_PRESS(VK_LEFT) && ps->dir != RIGHT)
{
ps->dir = LEFT;
}
else if (KEY_PRESS(VK_RIGHT) && ps->dir != LEFT)
{
ps->dir = RIGHT;
}
else if (KEY_PRESS(VK_ESCAPE))
{
ps->status = ESC;
break;
}
else if (KEY_PRESS(VK_SPACE))
{
//游戏要暂定
pause();//暂定和回复暂定
}
else if (KEY_PRESS(VK_F1))
{
if (ps->SleepTime >= 80)
{
ps->SleepTime -= 30;
ps->FoodWeight += 2;
}
}
else if (KEY_PRESS(VK_F2))
{
if (ps->FoodWeight > 2)
{
ps->SleepTime += 30;
ps->FoodWeight -= 2;
}
}
//走一步
SnakeMove(ps);
//睡眠一下
Sleep(ps->SleepTime);
} while (ps->status == OK);
}
上述代码有pause函数和虚拟按键,和SnakeMove函数没有介绍到
void pause()//暂停
{
while (1)
{
Sleep(300);
if (KEY_PRESS(VK_SPACE))
{
break;
}
}
}
在程序中需要添加宏定义:#define KEY_PRESS(VK) ( (GetAsyncKeyState(VK) & 0x1) ? 1 : 0 )
void SnakeMove(pSnake ps)
{
pSnakeNode pNext = (pSnakeNode)malloc(sizeof(SnakeNode));
if (pNext == NULL)
{
perror("SnakeMove()::malloc()");
return;
}
pNext->next = NULL;
switch (ps->dir)
{
case UP:
pNext->x = ps->pSnake->x;
pNext->y = ps->pSnake->y - 1;
break;
case DOWN:
pNext->x = ps->pSnake->x;
pNext->y = ps->pSnake->y + 1;
break;
case LEFT:
pNext->x = ps->pSnake->x - 2;
pNext->y = ps->pSnake->y;
break;
case RIGHT:
pNext->x = ps->pSnake->x + 2;
pNext->y = ps->pSnake->y;
break;
}
//下一个坐标处是否是食物
if (NextIsFood(ps, pNext))
{
//是食物就吃掉
EatFood(ps, pNext);
}
else
{
//不是食物就正常一步
NotEatFood(ps, pNext);
}
//检测撞墙
KillByWall(ps);
//检测撞到自己
KillBySelf(ps);
}
这里面又有5个函数不知道:NextIsFood EatFood NotEatFood KillByWall KillBySelf
//pSnakNode psn 是下一个节点的地址
//pSnake ps 维护蛇的指针
int NextIsFood(pSnake ps, pSnakeNode pNext)
{
if (ps->pFood->x == pNext->x && ps->pFood->y == pNext->y)
return 1;//下一个坐标处是食物
else
return 0;
}
void EatFood(pSnake ps, pSnakeNode pNext)
{
pNext->next = ps->pSnake;
ps->pSnake = pNext;
//打印蛇
pSnakeNode cur = ps->pSnake;
while (cur)
{
SetPos(cur->x, cur->y);
wprintf(L"%lc", BODY);
cur = cur->next;
}
ps->score += ps->FoodWeight;
//释放旧的食物
free(ps->pFood);
//新建食物
CreateFood(ps);
}
void NotEatFood(pSnake ps, pSnakeNode pNext)
{
//头插法
pNext->next = ps->pSnake;
ps->pSnake = pNext;
//释放尾结点
pSnakeNode cur = ps->pSnake;
while (cur->next->next)
{
SetPos(cur->x, cur->y);
wprintf(L"%lc", BODY);
cur = cur->next;
}
//将尾节点的位置打印成空白字符
SetPos(cur->next->x, cur->next->y);
printf(" ");
free(cur->next);
cur->next = NULL;//易错
}
//检测是否撞墙
void KillByWall(pSnake ps)
{
if (ps->pSnake->x == 0 ||
ps->pSnake->x == 112 ||
ps->pSnake->y == 0 ||
ps->pSnake->y == 52)
{
ps->status = KILL_BY_WALL;
}
}
//检测是否撞自己
void KillBySelf(pSnake ps)
{
pSnakeNode cur = ps->pSnake->next;//从第二个节点开始
while (cur)
{
if (cur->x == ps->pSnake->x && cur->y == ps->pSnake->y)
{
ps->status = KILL_BY_SELF;
return;
}
cur = cur->next;
}
}
此时程序总体还差一个GameEnd函数
void GameEnd(pSnake ps)
{
SetPos(30, 24);
switch (ps->status)
{
case ESC:
printf("主动退出游戏,正常退出\n");
break;
case KILL_BY_WALL:
printf("很遗憾,撞墙了,游戏结束\n");
break;
case KILL_BY_SELF:
printf("很遗憾,咬到自己了,游戏结束\n");
break;
}
pSnakeNode cur = ps->pSnake;
//释放蛇身的节点
while (cur)
{
pSnakeNode del = cur;
cur = cur->next;
free(del);
}
}
