C语言实现贪吃蛇游戏代码

一、实现效果
键位：使用wasd四个键位来控制方向，按q键退出（注意在终用英文输入法实现键控）
规则：蛇每吃一个豆会得10分，同时身体边长、移速加快
当蛇碰到墙壁或咬到自身时游戏结束，同时会输出游戏得分
二、部分代码解释
（1）用结构体定义蛇和豆
typedef struct Snakes
{
int x;
int y;
struct Snakes *next;
}snake;
snake *head,*tail;
struct Food
{
int x;
int y;
}food;
（2）打印墙壁
void creatgraph()
{
int i;
for (i = 0; i<58; i += 2)//打印上下边框
{
gotoprint(i, 0);
gotoprint(i, 26);
}
for (i = 1; i < 26; i++)
{
gotoprint(0, i);
gotoprint(56, i);
}
head = (snake*)malloc(sizeof(snake));
head->x = 16;
head->y = 15;
//gotoprint(head->x, head->y);
tail = (snake*)malloc(sizeof(snake));
snake *p = (snake*)malloc(sizeof(snake));
snake *q = (snake*)malloc(sizeof(snake));
p->x = 16;
p->y = 16;
q->x = 16;
q->y = 17;
head->next = p;
p->next = q;
q->next = tail;
//gotoprint(p->x, p->y);
//gotoprint(q->x, q->y);
tail->next = NULL;
tail->x = 4;
tail->y = 2;
}
void gotoxy(int x, int y)
{
COORD pos;
HANDLE hOutput;
pos.X = x;
pos.Y = y;
hOutput = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleCursorPosition(hOutput, pos);
}
void gotoprint(int x, int y)
{
gotoxy(x, y);
printf("■");
}
void gotodelete(int x, int y)
{
gotoxy(x, y);
printf(" ");
}
（3）生成豆
void creatfood()
{
srand((int)time(NULL));
lable:
food.y = rand() % (25 - 1 + 1) + 1;
food.x = rand() % (54 - 2 + 1) + 2;
if (food.x % 2 != 0)
{
food.x = food.x+1;
}
snake *judge = head;
while (1)
{
if (judge->next == NULL) break;
if (food.x == judge->x&&food.y == judge->y)
{
goto lable;
}
judge = judge->next;
}
gotoxy(food.x, food.y);
printf("⊙");
}
（4）点击控制函数
int ClickControl()
{
char c;
while (1)
{
if (Judge()==0) return 0;
if (_kbhit())
{
click = _getch();
}
MovingBody();
Eating();
}
return 1;
}
（5）移动控制
void MovingBody()
{
int count = 0;
int a = head->x, b = head->y;
snake *p = head;
while (1)
{
if (p->next == NULL) break;
gotodelete(p->x, p->y);
count++;
p = p->next;
}
switch (click)
{
case up:
head->y -= 1;
ChangeBody(a,b);
break;
case down:
head->y += 1;
ChangeBody(a,b);
break;
case left:
head->x -= 2;
ChangeBody(a,b);
break;
case right:
head->x += 2;
ChangeBody(a,b);
break;
case stop:
_getch();
break;
}
p = head;
while (1)
{
if (p->next == NULL) break;
gotoprint(p->x, p->y);
p = p->next;
}
p = head;
gotoxy(0, 28);
if (count <= 10) speed = 150;
else if (count > 10 && count <= 20) speed = 100;
else if (count > 20 && count <= 40) speed = 50;
else speed = 10;
Sleep(speed);
}
（6）更改蛇身
void ChangeBody(int a,int b)
{
snake *p = head->next;
int mid1, mid2,_mid1,_mid2;
mid1 = p->x;
mid2 = p->y;
while (1)
{
if (p->next->next == NULL) break;
_mid1 = p->next->x;
_mid2 = p->next->y;
p->next->x = mid1;
p->next->y = mid2;
mid1 = _mid1;
mid2 = _mid2;
p = p->next;
}
p = head->next;
{
p->x = a;
p->y = b;
}
}
