使用计算机图形设计积木游戏的程序
在 C 图形中， graphics.h 函数用于绘制不同的形状，如圆形、矩形等，以不同的格式（不同的字体和颜色）显示文本（任何消息）。通过使用 graphics.h 程序，可以设计动画和游戏。这些对初学者很有用。
使用的功能：
- rectangle(l, t, r, b) ：来自 graphics.h 头文件的函数，它从左（l）到右（r）和从上（t）到下（b）绘制一个矩形。
- line(a1, b1, a2, b2) : graphics.h 头文件中的一个函数，它从 (a1, b1) 点到 (a2, b2) 点绘制一条线。
- setfillstyle(pattern, color) : graphics.h 头文件中的一个函数，通过它可以给出绘图模式和特定颜色。
- floodfill(a, b, c)：来自 graphics.h 头文件的一个函数，通过它可以为特定的有界区域着色，以 (a, b) 为中心，c 是边框颜色。
- outtextxy(int x, int y, char * 字符串) : graphics.h 头文件中的一个函数，通过它可以打印任何语句，其中 x, y 是点的坐标，第三个参数包含字符串的地址要显示。
- settextstyle(int font, int direction, int font_size) ： graphics.h 头文件中的函数，可用于可打印文本的样式，其中 font 参数指定文本的字体。方向可以是 HORIZ_DIR（从左到右）或 VERT_DIR（从下到上）。
方法：
- 这是一个砖块游戏，从上面来的砖块是随机颜色的。
- 有3个 可以放置砖块的柱子。
- 如果两块相同颜色的积木相邻，它们都会消失，分数会增加 10 分。
- 如果砖块接触到游戏区域的顶部，那么游戏就结束了。下面是一段视频来解释游戏的运作方式。
