C++反弹球消砖块

游戏描述
一款用C++语言加上EasyX写的小游戏

游戏效果：

定义变量

#define width 400
#define high 600

int ball_x, ball_y;  //小球中心坐标
int vx, vy;    //小球速度
int radius;   //小球半径
int wood_x, wood_y;  //木板中心坐标
int brick_count;   //砖块数量
int brick_x, brick_y;  //砖块长宽
int tag[5][10];    //标记数组

初始化

void startup()
{
	
	initgraph(width, high);

	ball_x = 200;
	ball_y = 580;
	radius = 10;
	vx = 1;
	vy = -1;
	wood_x = 200;
	wood_y = 595;
	brick_count = 50;
	brick_x = 40;
	brick_y = 20;

	//做标记
	for (int i = 0; i < 5; i++)
		for (int j = 0; j < 10; j++)
			tag[i][j] = 0;

	BeginBatchDraw();
}

	//擦出圆
	setfillcolor(BLACK);
	solidcircle(ball_x, ball_y, radius);
	ball_x = ball_x + vx;
	ball_y = ball_y + vy;

				}
				if (ball_y + radius+1 >= i*brick_y&&ball_y - radius-1 <= (i + 1)*brick_y)
				{
					vy = -1 * vy;
				}
				
				tag[i][j] = 1;
				brick_count--;
				setfillcolor(BLACK);    //将击中的砖块用黑色覆盖掉
				fillrectangle(j*brick_x,i*brick_y,(j+1)*brick_x,(i+1)*brick_y);
				break;
			}
		}

	//结束游戏,砖块为零时，成功；挡板坐标大于高度，失败
	if (brick_count == 0||ball_y+radius>=high)
	{
		if (brick_count > 0)
			 MessageBox(NULL, L"You Lose!", L"打砖块", MB_RETRYCANCEL);
		else
		     MessageBox(NULL, L"You Win!", L"打砖块", MB_RETRYCANCEL);
	}

	FlushBatchDraw();
}

总结
在CSDN中，很少能够看到用C++和EasyX写的小程序，感觉对新手来说不是很友好
