消砖块游戏（EasyX重构进阶版）

如果没看过这篇文章的朋友可以先去这里反弹球消砖块C语言重构函数封装
因为这篇是C语言和EasyX结合的版本，也不是很难理解和实现

一个“屏保”

详细代码如下：

#include<conio.h>
#include<graphics.h>

#define high 480
#define width 640

int x, y;
int vx, vy;
int radius;

void startup()
{
	x = width / 2;
	y = high / 2;
	vx = 1;
	vy = 1;
	radius = 20;

	initgraph(width, high);
	BeginBatchDraw();
}

void clean()
{
	setcolor(BLACK);
	setfillcolor(BLACK);
	fillcircle(x, y, radius);
}

void show()
{
	setcolor(BLUE);
	setfillcolor(YELLOW);
	fillcircle(x, y, radius);
	FlushBatchDraw();
	Sleep(3);
}

void updateWithoutInput()
{
	x += vx;
	y += vy;
	
	if(x <= radius || x >= width - radius)
		vx = -vx;
	if(y <= radius || y >= high - radius)
		vy = -vy;
}

void updateWithInput()
{
}

void gameover()
{
	EndBatchDraw();
	closegraph();
}

int main()
{
	startup();
	while(1)
	{
		clean();
		updateWithoutInput();
		updateWithInput();
		show();
	}
	gameover();
	return 0;
}

添加一块挡板

效果演示如下：

详细代码如下：

#include<conio.h>
#include<graphics.h>

#define high 480
#define width 640

int x, y;					//小球's situation
int vx, vy;
int radius;
int x2, y2;					//挡板's central situation
int high2, width2;
int left, right, top, bottom;		

void startup()
{
	x = width / 2;				
	y = high / 2;
	vx = 1;
	vy = 1;
	radius = 20;

	high2 = high / 20;
	width2 = width / 5;
	x2 = width / 2;
	y2 = high - high2 / 2;
	left = x2 - width2 / 2;
	right = x2 + width2 / 2;
	top = y2 - high2 / 2;
	bottom = y2 + high2 / 2;

	initgraph(width, high);
	BeginBatchDraw();
}

void clean()			//擦除的效果
{
	setcolor(BLACK);
	setfillcolor(BLACK);
	fillcircle(x, y, radius);
	bar(left, top, right, bottom);
}

void show()
{
	setcolor(BLUE);
	setfillcolor(YELLOW);
	fillcircle(x, y, radius);
	setfillcolor(BROWN);
	bar(left, top, right, bottom);

	FlushBatchDraw();
	Sleep(3);
}

void updateWithoutInput()
{
	x += vx;
	y += vy;
	
	if(x <= radius || x >= width - radius)
		vx = -vx;
	if(y <= radius || y >= high - radius)
		vy = -vy;
}

void updateWithInput()
{
}

void gameover()
{
	EndBatchDraw();
	closegraph();
}

int main()
{
	startup();
	while(1)
	{
		clean();
		updateWithoutInput();
		updateWithInput();
		show();
	}
	gameover();
	return 0;
}

控制挡板接球

效果演示如下：

这一块只是完善了用户输入部分的函数

详细代码：

#include<conio.h>
#include<graphics.h>

#define high 480
#define width 640

int x, y;					//小球's situation
int vx, vy;
int radius;
int x2, y2;					//挡板's central situation
int high2, width2;
int left, right, top, bottom;		

void startup()
{
	x = width / 2;				
	y = high / 2;
	vx = 1;
	vy = 1;
	radius = 20;

	high2 = high / 20;
	width2 = width / 5;
	x2 = width / 2;
	y2 = high - high2 / 2;
	left = x2 - width2 / 2;
	right = x2 + width2 / 2;
	top = y2 - high2 / 2;
	bottom = y2 + high2 / 2;

	initgraph(width, high);
	BeginBatchDraw();
}

void clean()			//擦除的效果
{
	setcolor(BLACK);
	setfillcolor(BLACK);
	fillcircle(x, y, radius);
	bar(left, top, right, bottom);
}

void show()
{
	setcolor(BLUE);
	setfillcolor(YELLOW);
	fillcircle(x, y, radius);
	setcolor(BLUE);
	setfillcolor(BROWN);
	bar(left, top, right, bottom);

	FlushBatchDraw();
	Sleep(3);
}

void updateWithoutInput()
{		//考虑到球位于挡板上或挡板下的情况
	if(((y + radius >= top) && (y + radius < bottom - high2 / 3)) || (( y - radius <= bottom) && (y - radius > top - high2 / 3)))
		if((x >= left) && (x <= right))
			vy = -vy;

	x += vx;
	y += vy;
	
	if(x <= radius || x >= width - radius)
		vx = -vx;
	if(y <= radius || y >= high - radius)
		vy = -vy;
}

void updateWithInput()
{
	char input;
	if(kbhit())
	{
		input = getch();
		if(input == 'a' && left > 0)
		{
			x2 -= 15;
			left = x2 - width2 / 2;
			right = x2 + width2 / 2;
		}
		if(input == 'd' && right < width)
		{
			x2 += 15;
			left = x2 - width2 / 2;
			right = x2 + width2 / 2;
		}
		if(input == 'w' && top > 0)
		{
			y2 -= 15;
			top = y2 - high2 / 2;
			bottom = y2 + high2 / 2;
		}
		if(input == 's' && bottom < high)
		{
			y2 += 15;
			top = y2 - high2 / 2;
			bottom = y2 + high2 / 2;
		}
	}
}

void gameover()
{
	EndBatchDraw();
	closegraph();
}

int main()
{
	startup();
	while(1)
	{
		clean();
		updateWithoutInput();
		updateWithInput();
		show();
	}
	gameover();
	return 0;
}
