主要本人初学C语言做的简易小游戏,许多地方还需改进并且有不足之处,在以后将更加完善。
一、功能介绍
(1)蛇可以上下左右移动(速度可以更改),且颜色可以更改;
(2)食物随机出现;
(3)有加分数功能的实现;
(4)将食物吃掉之后蛇的长度也随之改变;
二、编写步骤
主要的相关步骤不在此复述,代码如下。
#define _CRT_SECURE_NO_WARNINGS 1
#include
#include
//包含easyx图形库
#include
#define WIN_WIDTH 640
#define WIN_HEIGHT 480
#define MAX_SNAKE 300 //蛇的最大节数
//枚举
enum DIR//枚举蛇的方向
{
UP,
DOWN,
RIGHT,
LEFT,
};
struct Food//食物
{
int x;
int y;
DWORD color;
bool flag;//是否被吃掉,是否重新生成食物
}food;
struct Pos
{
int x;
int y;
DWORD color;
};
struct Snake
{
int num;//当前节数
int dir;//蛇的方向
int score;//分数
int size;//蛇的高和宽
int speed;//蛇的移动速度
//表示每一节蛇的坐标、数组
struct Pos coor[MAX_SNAKE];
}snake;
void GameInit()
{
//设置随机数种子
srand(GetTickCount());
snake.num = 3;
snake.dir = RIGHT;
snake.score = 0;
snake.size = 10;
snake.speed = 10;
snake.coor[2].x = 0;
snake.coor[2].y = 0;
snake.coor[2].color = RGB(rand() % 256, rand() % 256, rand() % 256);//随机生成三个数,表示颜色
snake.coor[1].x = 10;
snake.coor[1].y = 0;
snake.coor[1].color = RGB(rand() % 256, rand() % 256, rand() % 256);//随机生成三个数,表示颜色
snake.coor[0].x = 20;
snake.coor[0].y = 0;
snake.coor[0].color = RGB(rand() % 256, rand() % 256, rand() % 256);//随机生成三个数,表示颜色
//初始化食物
food.x = rand() % (WIN_WIDTH / 10) * 10;
food.y = rand() % (WIN_HEIGHT / 10) * 10;
food.color = RGB(rand() % 256, rand() % 256, rand() % 256);//随机生成三个数,表示颜色
food.flag = true;
}
void GameDraw()
{
cleardevice();
for (int i = 0; i < snake.num; i++)
{
//设置填充颜色
setfillcolor(snake.coor[i].color);
//矩形
fillrectangle(snake.coor[i].x, snake.coor[i].y, snake.coor[i].x + 10, snake.coor[i].y + 10);
}
//绘制食物
if (food.flag)
{
setfillcolor(food.color);
solidellipse(food.x, food.y, food.x + 10, food.y + 10);
}
//分数
char temp[20] = " ";
sprintf(temp, "分数:%d", snake.score);
outtextxy(10, 10, temp);
}
void GameMove()
{
for (int i = snake.num - 1; i > 0; i--)
{
snake.coor[i].x = snake.coor[i - 1].x;
snake.coor[i].y = snake.coor[i - 1].y;
}
switch (snake.dir)
{
case UP:
snake.coor[0].y -= snake.speed;
if (snake.coor[0].y < 0)
{
snake.coor[0].y = WIN_HEIGHT;
}
break;
case DOWN:
snake.coor[0].y += snake.speed;
if (snake.coor[0].y > WIN_HEIGHT)
{
snake.coor[0].y = 0;
}
break;
case LEFT:
snake.coor[0].x -= snake.speed;
if (snake.coor[0].x < 0)
{
snake.coor[0].x = WIN_WIDTH;
}
break;
case RIGHT:
snake.coor[0].x += snake.speed;
if (snake.coor[0].x>WIN_WIDTH)
{
snake.coor[0].x = 0;
}
break;
}
}
void GameControl()
{
//获取键盘输入,_getch();
char key = _getch();
switch (key)
{
case 72:
if (snake.dir != DOWN)
{
snake.dir = UP;
}
break;
case 80:
if (snake.dir != UP)
{
snake.dir = DOWN;
}
break;
case 75:
if (snake.dir != RIGHT)
{
snake.dir = LEFT;
}
break;
case 77:
if (snake.dir != LEFT)
{
snake.dir = RIGHT;
}
break;
}
printf("%d\n", key);
}
void Creatfood()
{
if (!food.flag)
{
food.x = rand() % (WIN_WIDTH / 10) * 10;
food.y = rand() % (WIN_HEIGHT / 10) * 10;
food.color = RGB(rand() % 256, rand() % 256, rand() % 256);
food.flag = true;
}
}
void EatFood()
{
if (food.flag&&snake.coor[0].x == food.x&&snake.coor[0].y == food.y)
{
food.flag = false;
snake.num++;
snake.score += 10;
snake.coor[snake.num - 1].color = RGB(rand() % 256, rand() % 256, rand() % 256);//随机生成三个数
Creatfood();
}
}
int main()
{
//创建窗口,Init初始化 graphics图形窗口
initgraph(WIN_WIDTH, WIN_HEIGHT, SHOWCONSOLE);
setbkcolor(RGB(207, 214, 299));//设置颜色
cleardevice();//刷新窗口
GameInit();
while (1)
{
GameDraw();
GameMove();
if (_kbhit())
{
GameControl();
}
EatFood();
Sleep(90);
}
getchar();
return 0;
}
三.效果展示
视频将不在此展示,只上传图片样式。
本次制作的简易游戏有许多功能尚未完善,之后将弥补空缺功能,而且游戏还可以扩大开发效果。
