DevC++ 小游戏 代码

DevC++ 是一款非常受欢迎的编程软件，很多程序员都在使用它开发各种应用程序、小工具和游戏，今天我们来分享一款使用 DevC++ 编写的小游戏代码。

这款小游戏是一款经典的贪吃蛇游戏，玩家通过控制一条蛇来吃掉屏幕上的食物，每吃掉一块食物，蛇的长度就会增加一些。同时，玩家需要避开蛇头碰到屏幕边缘或者蛇的身体，否则游戏就会结束。

以下是该游戏的代码实现：

#include<graphics.h>
#include<stdlib.h>
#include<conio.h>
#include<time.h>
#define UP 72
#define DOWN 80
#define LEFT 75
#define RIGHT 77
struct SnakeNode
y;
;
struct Snake
{
    SnakeNode snakeBody[400];
    int length;
    int direction;
};
void GameOver();
void InitGame();
void DrawSnake(Snake *snake);
void DrawFood(int x,int y);
void MoveSnake(Snake *snake);
bool EatFood(Snake *snake,int x,int y);
int main()
{
    InitGame();
    setbkcolor(EGERGB(0,0,0));
    cleardevice();
    Snake *snake=new Snake;
    DrawSnake(snake);
    srand((unsigned)time(NULL));
    int x=rand()%60*10+30,y=rand()%40*10+30;
    DrawFood(x,y);
    while(1)
    {
        if(EatFood(snake,x,y))
        {
            snake->length++;
            x=rand()%60*10+30;
            y=rand()%40*10+30;
            DrawFood(x,y);
        }
        MoveSnake(snake);
        if(snake->snakeBody[0].x<20||snake->snakeBody[0].x>630||snake->snakeBody[0].y<20||snake->snakeBody[0].y>430)
            GameOver();
        for(int i=1;i<snake->length;i++)
            if(snake->snakeBody[0].x==snake->snakeBody[i].x&&snake->snakeBody[0].y==snake->snakeBody[i].y)
                GameOver();
        cleardevice();
        DrawSnake(snake);
        DrawFood(x,y);
        delay(200);
        if(kbhit())
            switch(getch())
            {
            case UP:
                if(snake->direction!=DOWN)snake->direction=UP;
                break;
            case DOWN:
                if(snake->direction!=UP)snake->direction=DOWN;
                break;
            case LEFT:
                if(snake->direction!=RIGHT)snake->direction=LEFT;
                break;
            case RIGHT:
                if(snake->direction!=LEFT)snake->direction=RIGHT;
                break;
            case 27:
                delete []snake;
                closegraph();
                exit(0);
                break;
            }
    }
}
void InitGame()
{
    initgraph(640,480);
    setbkcolor(EGERGB(0,0,0));
    setcolor(EGERGB(255,255,255));
    settextstyle(18,0,"Arial");
    outtextxy(260,200,"Press Any Key To Start!");
    getch();
}
void GameOver()
{
    setbkcolor(EGERGB(0,0,0));
    setcolor(EGERGB(255,255,255));
    settextstyle(18,0,"Arial");
    outtextxy(270,220,"Game Over!");
    getch();
    delete []snake;
    closegraph();
    exit(0);
}
void DrawSnake(Snake *snake)
{
    snake->snakeBody[0].x=320;
    snake->snakeBody[0].y=240;
    snake->length=3;
    snake->direction=RIGHT;
    for(int i=1;i<snake->length;i++)
    {
        snake->snakeBody[i].x=snake->snakeBody[0].x-i*10;
        snake->snakeBody[i].y=snake->snakeBody[0].y;
    }
    for(int i=0;i<snake->length;i++)
    {
        setfillcolor(EGERGB(255,255,255));
        fillcircle(snake->snakeBody[i].x,snake->snakeBody[i].y,5);
    }
}
void DrawFood(int x,int y)
{
    setfillcolor(EGERGB(255,0,0));
    solidcircle(x,y,5);
}
void MoveSnake(Snake *snake)
{
    for(int i=snake->length-1;i>0;i--)
    {
        snake->snakeBody[i].x=snake->snakeBody[i-1].x;
        snake->snakeBody[i].y=snake->snakeBody[i-1].y;
    }
    switch(snake->direction)
    {
    case UP:
        snake->snakeBody[0].y-=10;break;
    case DOWN:
        snake->snakeBody[0].y+=10;break;
    case LEFT:
        snake->snakeBody[0].x-=10;break;
    case RIGHT:
        snake->snakeBody[0].x+=10;break;
    }
}
bool EatFood(Snake *snake,int x,int y)
{
    if(snake->snakeBody[0].x-10<=x&&snake->snakeBody[0].x+10>=x&&snake->snakeBody[0].y-10<=y&&snake->snakeBody[0].y+10>=y)
        return true;
    else
        return false;
}

以上代码非常详细地实现了贪吃蛇游戏的核心逻辑，包括初始化游戏、绘制蛇身和食物、移动蛇身、检测吃掉食物、检测游戏结束等功能。如果你也想开发一个自己的小游戏，可以通过对这个代码进行理解和修改来实现自己的创意游戏。
