贪吃蛇
四、核心的实现
游戏测试
c
#include <locale.h>
void test()
{
int ch = 0;
srand((unsigned int)time(NULL));//时间戳,用来实现随机数
do
{
Snake snake = { 0 };
GameStart(&snake);
GameRun(&snake);
GameEnd(&snake);
SetPos(20, 15);
printf("再来⼀局吗?(Y/N):");
ch = getchar();
getchar();
} while (ch == 'Y');
SetPos(0, 27);
}
int main()
{
//修改当前地区为本地模式,为了⽀持中⽂宽字符的打印
setlocale(LC_ALL, "");
//测试逻辑
test();
return 0;
}
1、GameStart
(1)控制台窗口大小和名字设置
c
system("mode con cols=100 lines=30");
system("title 贪吃蛇");
(2)光标隐藏
c
HANDLE houtput = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_CURSOR_INFO CursorInfo;
GetConsoleCursorInfo(houtput, &CursorInfo);
CursorInfo.bVisible = false;
SetConsoleCursorInfo(houtput, &CursorInfo);
(3)打印欢迎界面
c
void WelcomeToGame()
{
SetPos(40, 15);
printf("欢迎来到贪吃蛇⼩游戏");
SetPos(40, 25);// "按任意键继续"的出现的位置
system("pause");//可以让页面暂停在这个位置,直到用户按下一个键
system("cls");//清除屏幕
SetPos(25, 12);
printf("⽤ ↑ . ↓ . ← . → 分别控制蛇的移动, F3为加速,F4为减速\n");
SetPos(25, 13);
printf("加速将能得到更⾼的分数。\n");
SetPos(40, 25);
// "按任意键继续"的出现的位置,这里可以让文字出现的位置看起来比较美观
system("pause");
system("cls");
}
(4)创建地图
组成地图的小格子需要用宽字符打印
58行就打印29次
c
#define WALL L'□'
//在头文件中定义
void CreateMap()
{
//上
int i = 0;
for (i = 0; i < 29; i++)
{
wprintf(L"%lc", WALL);
}
//下
SetPos(0, 26);
for (i = 0; i < 29; i++)
{
wprintf(L"%lc", WALL);
}
//左
for (i = 1; i <= 25; i++)
{
SetPos(0, i);
wprintf(L"%lc", WALL);
}
//右
for (i = 1; i <= 25; i++)
{
SetPos(56, i);
wprintf(L"%lc", WALL);
}
}
(5)初始化蛇
c
void InitSnake(pSnake ps)
{
int i = 0;
pSnakeNode cur = NULL;
for (i = 0; i < 5; i++)
{
cur = (pSnakeNode)malloc(sizeof(SnakeNode));//创建蛇身节点
if (cur == NULL)
{
perror("malloc fail");
exit(1);
}
cur->next = NULL;
cur->x = POS_X + 2 * i;//将蛇的节点由蛇尾到蛇头创建好
cur->y = POS_Y;
if (ps->_pSnake == NULL)
{
ps->_pSnake = cur;//若没有蛇身节点则建立的节点为蛇身节点
}
else
{
cur->next = ps->_pSnake;
ps->_pSnake = cur;//若有蛇身节点则新创建的节点成为头节点
}
}
cur = ps->_pSnake;
while (cur)
{
SetPos(cur->x, cur->y);
wprintf(L"%lc", BODY);//将蛇的身体依据链表打印出来
cur = cur->next;
}
ps->_dir = RIGHT;//初始蛇的方向
ps->_food_weight = 10;//每个食物的分数
ps->_sleep_time = 200;//每两次打印蛇身的间隔,也就是蛇身的速度
ps->_sorce = 0;//初始总分数
ps->_status = OK;//蛇的初始状态
}
(6)创建第一个食物
c
void CreateFood(pSnake ps)
{
int x = 0;
int y = 0;
again:
do
{
x = rand() % 53 + 2;//我们要的x坐标值介于2~54间,任意数%53得到的值介于0~52,加上2就在2~56范围
y = rand() % 25 + 1;//我们要的y坐标值介于1~25间,任意数%25得到的值介于0~24,加上1就在1~25范围
//随机数时间戳,根据时间计算的数据,由于时间是不可修改切没有相同时候的,所以它产生的数字被认为是随机数
} while (x % 2 != 0);
pSnakeNode cur = ps->_pSnake;//记录蛇头结点
while (cur)
{
if (x == cur->x && y == cur->y)
{
goto again;
}
cur = cur->next;
}//如果食物与蛇身上某一节点重合了,则回到again处重新生成
pSnakeNode pFood = (pSnakeNode)malloc(sizeof(SnakeNode));//不重合就生成食物
if (pFood == NULL)
{
perror("malloc fail");
exit(2);
}
pFood->x = x;
pFood->y = y;
pFood->next = NULL;
SetPos(x, y);
wprintf(L"%lc", FOOD);//在对应位置处打印食物
ps->_pFood = pFood;
}
最终的GameStart
c
void GameStart(pSnake ps)
{
//设置控制台窗⼝的⼤⼩,30⾏,100列
//mode 为DOS命令
system("mode con cols=100 lines=30");
//设置cmd窗⼝名称
system("title 贪吃蛇");
//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);
//影藏光标操作
CONSOLE_CURSOR_INFO CursorInfo;
//获取控制台光标信息
GetConsoleCursorInfo(hOutput, &CursorInfo);
//隐藏控制台光标
CursorInfo.bVisible = false;
//设置控制台光标状态
SetConsoleCursorInfo(hOutput, &CursorInfo);
//打印欢迎界⾯
WelcomeToGame();
//打印地图
CreateMap();
//初始化蛇
InitSnake(ps);
//创造第⼀个⻝物
CreateFood(ps);
}
2、GameRun
(1)定义一个宏来检测按键状态
c
#define KEY_PRESS(VK) ((GetAsyncKeyState(VK)&0x1) ? 1 : 0)
在上一篇博文中我们介绍了GetAsyncKeyState函数,我们封装一个宏可以判断某个键是否被按下
(2)PrintHelpInfo
c
void PrintHelpInfo()
{
SetPos(64, 14);
wprintf(L"%ls", L"不能穿墙,不能咬到自己");
SetPos(64, 16);
wprintf(L"%ls", L"用 ↑. ↓ . ← . → 来控制蛇的移动");
SetPos(64, 18);
wprintf(L"%ls", L"按F3加速,F4减速");
SetPos(64, 20);
wprintf(L"%ls", L"按ESC退出游戏,按空格暂停游戏");
SetPos(64, 24);
wprintf(L"%ls", L"s_little_monster_倾情制作");
}
(3)SnakeMove
c
void SnakeMove(pSnake ps)
{
pSnakeNode pNextNode = (pSnakeNode)malloc(sizeof(SnakeNode));//开辟预测的下一个节点
if (pNextNode == NULL)
{
perror("malloc fail");
exit(3);
}
switch (ps->_dir)//用switch语句判断此时蛇的走向
{
case UP:
pNextNode->x = ps->_pSnake->x;
pNextNode->y = ps->_pSnake->y - 1;
break;
case DOWN:
pNextNode->x = ps->_pSnake->x;
pNextNode->y = ps->_pSnake->y + 1;
break;
case LEFT:
pNextNode->x = ps->_pSnake->x - 2;//注意左右移动是加减2
pNextNode->y = ps->_pSnake->y;
break;
case RIGHT:
pNextNode->x = ps->_pSnake->x + 2;
pNextNode->y = ps->_pSnake->y;
break;
}
if (NextIsFood(pNextNode, ps))
{
EatFood(pNextNode,ps);
}
else
{
NoFood(pNextNode, ps);
}
//判断下一个位置是否为食物,是则进入EatFood,不是则进入NoFood
KillBySelf(ps);
KillByWall(ps);//检查是否撞到自己或墙而死亡
}
(4)NextIsFood
c
int NextIsFood(pSnakeNode pn,pSnake ps)
{
return (ps->_pFood->x == pn->x && ps->_pFood->y == pn->y);
//如果当前位置是食物则返回非0值,不是返回0
}
(5)EatFood
c
void EatFood(pSnakeNode pn, pSnake ps)
{
ps->_pFood->next = ps->_pSnake;
ps->_pSnake = ps->_pFood;//吃掉食物,让食物成为蛇的头节点
free(pn);//因为节点pn与节点_pFood是一个节点,所以free掉其中的一个
pn = NULL;
pSnakeNode cur = ps->_pSnake;
while (cur)
{
SetPos(cur->x, cur->y);
wprintf(L"%lc", BODY);
cur = cur->next;
}//打印蛇身
ps->_sorce += ps->_food_weight;//加分
CreateFood(ps);//重新制造食物
}
(6)NoFood
c
void NoFood(pSnakeNode pn, pSnake ps)
{
pn->next = ps->_pSnake;
ps->_pSnake = pn;//同EatFood,将下一节点成为头结点
pSnakeNode cur = ps->_pSnake;
while (cur->next->next != NULL)
{
SetPos(cur->x, cur->y);
wprintf(L"%lc", BODY);
cur = cur->next;
}//将除了尾节点以外的节点打印
SetPos(cur->next->x, cur->next->y);
printf(" ");//将尾节点打印为空格
free(cur->next);//free掉尾节点
cur->next = NULL;
}
(7)KillBySelf
c
void KillBySelf(pSnake ps)
{
pSnakeNode pur = ps->_pSnake->next;
while (pur)
{
//当此时的蛇头位置与蛇身某一节点重合时
if (pur->x == ps->_pSnake->x && pur->y == ps->_pSnake->y)
{
ps->_status = KILL_BY_SELF;//修改状态为 KILL_BY_SELF
break;
}
pur = pur->next;
}
}
(8)KillByWall
c
void KillByWall(pSnake ps)
{
//当此时的蛇头位置与墙体重合时
if (ps->_pSnake->x == 0 || ps->_pSnake->x == 56 || ps->_pSnake->y == 0 || ps->_pSnake->y == 26)
{
ps->_status = KILL_BY_WALL;//修改状态为 KILL_BY_WALL
}
}
最终的GameRun
c
void GameRun(pSnake ps)
{
PrintHelpInfo();//游戏玩法帮助打印
do
{
SetPos(64, 10);
printf("总分数:%d\n", ps->_sorce);
SetPos(64, 11);
printf("当前食物的分数:%2d\n", ps->_food_weight);
//检测键是否被按下
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_SPACE))
{
Pause();//暂停,等待再按下空格继续
}
else if (KEY_PRESS(VK_ESCAPE))
{
ps->_status = END_NORMAL;
}
else if (KEY_PRESS(VK_F3))//F3为加速,休眠时间变少也就是蛇的速度变快,每个食物分数增加2
{
if(ps->_sleep_time > 80)//速度不能太快
{
ps->_sleep_time -= 30;
ps->_food_weight += 2;
}
}
else if (KEY_PRESS(VK_F4))//F4为减速,休眠时间变多也就是蛇的速度变慢,每个食物分数减少2
{
if(ps->_food_weight > 2)//食物分数要在2分以上
{
ps->_sleep_time += 30;
ps->_food_weight -= 2;
}
}
SnakeMove(ps);//蛇每走一步要进行的活动
Sleep(ps->_sleep_time);//走一步休眠的时间,也就是蛇的速度
} while (ps->_status == OK);//当游戏状态为OK时循环继续
}
3、GameEnd
当游戏状态不为OK时,告知游戏结束的原因并释放蛇身
c
void GameEnd(pSnake ps)
{
SetPos(24, 12);
switch (ps->_status)
{
case END_NORMAL:
wprintf(L"主动结束游戏");
break;
case KILL_BY_SELF:
wprintf(L"撞到自己了,游戏结束");
break;
case KILL_BY_WALL:
wprintf(L"撞到墙了,游戏结束");
break;
}
pSnakeNode pur = ps->_pSnake;
while (pur)
{
pSnakeNode del = pur;
pur = pur->next;
free(del);
}
}
