《Pong》是一款游戏,内容简单,只有一个拍子和球
游戏是需要不断更新界面的,这种更新叫做游戏循环,把游戏封装成一个类就是Game类

这是一个项目模板,至于详细内容,下期再讲,你只需知道GameHz是1秒内游戏刷新的次数,gamename是游戏的名字。
警告:运行过程不要修改gamename
我们将在第二章好好讲讲Game类
《Pong》需要什么?
拍子,球,界面
拍子不用封装,一个int就够了
球得用两个int,和一个enum,把它封装成一个class ball类
警告:不要习惯用struct封装,不要习惯定义一个变量来代表一个对象
拍子:
int wally=0,wallwindy=4;
class Ball:
class Ball{
public:
int x,y;
enum{
up=1,donw=-1,left=2,right=-2,
ul=3,ur=-3,dl=4,dr=-4
}status;
void out(){
gotoxy(x,y);
cerr<<"○";
}
}ball;
警告:不要把所有成员变量设成公用,我这是为了方便......
void Input(){//检测
if(GetConsoleWindow()==Gwin){
//...
if(kd(VK_ESCAPE)){
GameEnd();

if(kd(107)){

if(kd(109)){
GameHz--;
}

int &bx=ball.x,&by=ball.y;
switch(ball.status){
case Ball::up:

if(by-wally==4){
//..

这些代码是检测发生的事件,其中有一部分未完成,为了方便。
void Output(){//输出
ball.out();
for(int i=0;i
输出球和拍子
#include
#include

#include
#include

#include
#define kd(VK_NONAME) ((GetAsyncKeyState(VK_NONAME) & 0x8000) ? 1:0)
using namespace std;
const char *gamename="Pong";
int GameHz=60;
HWND Gwin;
#define ISRUN 1//...
void gotoxy(int x, int y){
COORD pos={(short)x,(short)y};
HANDLE hOut=GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleCursorPosition(hOut,pos);
}
void noedit(){
HANDLE hStdin=GetStdHandle(STD_INPUT_HANDLE);
DWORD mode;
GetConsoleMode(hStdin,&mode);
mode&=~ENABLE_QUICK_EDIT_MODE;
mode&=~ENABLE_INSERT_MODE;
mode&=~ENABLE_MOUSE_INPUT;
SetConsoleMode(hStdin,mode);
}
void HideCursor(){
CONSOLE_CURSOR_INFO cur={1,0};
SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE),&cur);
}
void ShowCursor(){
CONSOLE_CURSOR_INFO cur={1,1};
SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE),&cur);
}
gotoxy是一个很好的函数,特有用
noedit是禁止快速编译插入模式
另外2个是影藏/显示光标
int wally=0,wallwindy=4;
class Ball{
public:
int x,y;
enum enums{
up=1,donw=-1,left=2,right=-2,
ul=3,ur=-3,dl=4,dr=-4
}status;
void out(){
gotoxy(x,y);
cerr<<"○";
}
Ball(){
x=rand()%60;
y=rand()%30;
status=left;
}
}ball;
定义了一个Ball类,一个Ball类对象ball,int变量wally,和宽度

Game是一个very very good的封装类,我们将在第二章好好讲讲Game类
int main(){
HideCursor();
noedit();
Gwin=GetConsoleWindow();
Game game;
game.GameLoop();
}
虽然Game是一个very very good的封装类,但程序的入口一定是main/WinMain函数

本章内我们做了《Pong》这个游戏但仍不完善,我也不会完善,我们将会在之后讲讲这里面的Bug
我是杨某一辰,期待你的关注!
