C语言实现反弹球游戏分享！

C语言小游戏——反弹球（简单的图形化界面），供大家参考，具体内容如下

1.环境准备和安装

2.Eaxy X功能的简单介绍

3.反弹球游戏主函数框架

  int main (void)  {   starup();//数据初始化   while(1)   {    show();//画面初始化    updateWithoutInput();//与用户输入无关的更新    updateWithInput();//与用户输入有关的更新    }     }

4.头文件的加载和全局变量的设定

  #include <graphics.h>  #include <conio.h>  #include <stdlib.h>  #include <time.h>    //全局变量  int high,width;//游戏尺寸  int ball_x,ball_y,ball_r;//球  int board_x,board_y,board_long,board_bottom;//木板  int gaol_x,gaol_y,gaol_long;//目标  int velocity_x,velocity_y;//速度

5.第一个函数starup() 全局变量的初始化

  void startup()  {   high=540;width=480;//游戏尺寸   ball_y=30;ball_x=width/3;ball_r=15;//球的坐标     board_y=high/2;board_x=width/2;//木板   board_long=150;board_bottom=10;     gaol_y=2;   gaol_x=width/2;   gaol_long=20; //目标第一个点的坐标      velocity_x=1,velocity_y=1;//速度     initgraph(width,high);  }

6.第二个函数show() 打印画面

  void show()  {   setbkcolor(RGB(255,255,255));   cleardevice();//清屏     setfillcolor(RGB(0,0,255));   fillcircle(ball_x,ball_y,ball_r);     setfillcolor(RGB(0,0,0));   fillrectangle(board_x,board_y,board_x+board_long,board_y+board_bottom);     setfillcolor(RGB(255,0,0));   fillrectangle(gaol_x,gaol_y,gaol_x+gaol_long,gaol_y+gaol_long);      }

7.第三个函数updateWithoutInput();与输入无关的更新

  void updateWithoutInpurt()  {   ball_x+=velocity_x;   ball_y+=velocity_y;     if(ball_x==1||ball_x==width-2)//碰壁反弹     velocity_x=-velocity_x;   if(ball_y==1||ball_y==high-2)    velocity_y=-velocity_y;     if(ball_y==board_y&&(ball_x>=board_x&&ball_x<board_x+board_long))//碰木板反弹     velocity_y=-velocity_y;   if(ball_y==board_y+board_bottom&&(ball_x>=board_x&&ball_x<board_x+board_long))//碰木板反弹     velocity_y=-velocity_y;     if((ball_x>gaol_x&&ball_x<gaol_x+gaol_long)&&(ball_y>gaol_y&&ball_y<gaol_y+gaol_long))//如果球击中目标   {    srand((unsigned)time(NULL));/*做随机数产生种子*/    gaol_y=rand()%(high/2-gaol_long)+1;    gaol_x=rand()%(width/2-gaol_long)+1;   }    }

功能：

* 碰壁反弹
* 碰木板反弹
* 如果球碰到目标，目标重新刷新

8.第四个函数 updateWithInput();与用户输入有关的更新

  void updateWithInpurt()  {    char input;   if(kbhit())   {    input=getch();    if(input=='w'&&board_y>1)     board_y-=10;    if(input=='s'&&board_y+board_bottom<high-2)     board_y+=10;    if(input=='a'&&board_x>1)     board_x-=10;    if(input=='d'&&board_x+board_long<width-2)     board_x+=10;   }   }

因为是以像素为单位绘画，所以每次移动10个单位

完整代码

  #include <graphics.h>  #include <conio.h>  #include <stdlib.h>  #include <time.h>    //全局变量  int high,width;//游戏尺寸  int ball_x,ball_y,ball_r;//球  int board_x,board_y,board_long,board_bottom;//木板  int gaol_x,gaol_y,gaol_long;//目标  int velocity_x,velocity_y;//速度    void startup()  {   high=540;width=480;//游戏尺寸   ball_y=30;ball_x=width/3;ball_r=15;//球的坐标     board_y=high/2;board_x=width/2;//木板   board_long=150;board_bottom=10;     gaol_y=2;   gaol_x=width/2;   gaol_long=20; //目标第一个点的坐标      velocity_x=1,velocity_y=1;//速度     initgraph(width,high);        }     void show()  {   setbkcolor(RGB(255,255,255));   cleardevice();//清屏     setfillcolor(RGB(0,0,255));   fillcircle(ball_x,ball_y,ball_r);     setfillcolor(RGB(0,0,0));   fillrectangle(board_x,board_y,board_x+board_long,board_y+board_bottom);     setfillcolor(RGB(255,0,0));   fillrectangle(gaol_x,gaol_y,gaol_x+gaol_long,gaol_y+gaol_long);    }    void updateWithoutInpurt()  {   ball_x+=velocity_x;   ball_y+=velocity_y;     if(ball_x==1||ball_x==width-2)//碰壁反弹     velocity_x=-velocity_x;   if(ball_y==1||ball_y==high-2)    velocity_y=-velocity_y;     if(ball_y>board_y&&(ball_x>=board_x&&ball_x<board_x+board_long))//碰木板反弹     velocity_y=-velocity_y;   if(ball_y==board_y+board_bottom&&(ball_x>=board_x&&ball_x<board_x+board_long))//碰木板反弹     velocity_y=-velocity_y;     if((ball_x>gaol_x&&ball_x<gaol_x+gaol_long)&&(ball_y>gaol_y&&ball_y<gaol_y+gaol_long))//如果球击中目标   {    srand((unsigned)time(NULL));/*做随机数产生种子*/    gaol_y=rand()%(high/2-gaol_long)+1;    gaol_x=rand()%(width/2-gaol_long)+1;   }    }    void updateWithInpurt()  {    char input;   if(kbhit())   {    input=getch();    if(input=='w'&&board_y>1)     board_y-=10;    if(input=='s'&&board_y+board_bottom<high-2)     board_y+=10;    if(input=='a'&&board_x>1)     board_x-=10;    if(input=='d'&&board_x+board_long<width-2)     board_x+=10;   }   }    int main(void)  {   startup();   while(1)   {    show();    updateWithoutInpurt();    updateWithInpurt();   }   }
