精细绘图及动画 制个程序是本人自己编写，所以这里能后做出详细解释。程序运行后会在屏幕上用triplex_font显示“press any key for set off”，下方是用基本的线条画出的发射架（有点粗糙），即程序中的DrawGun()函数，当按下任意键后，将在发射架上方出现一个用横线填充的飞机，同时背景被繁星填充，此时必须按住任意键不放，否则飞机将不会发射。发射完成后，即飞机坐标小于0，将出现一句话：\"successfully!!!,press ESC to quit\",若中途按ESC退出，则飞机Y坐标不小于0，将出现\"failue,...\"这句话。-sophisticated graphics and animation system procedure is the preparation of my own, here is an ability to make a detailed explanation. After running on the screen with triplex_font shows that the "press any key for set off", is the bottom line with the basic head of the launcher (somewhat rough), that the procedures DrawGun () function, when pressed any button, will be on the launch pad tower side there with a hyphen Filled with the aircraft, while the background was filled with stars, this time to be arbitrary button is pressed it, it will not launch aircraft. Fired Upon completion, the coordinates of the aircraft is less than 0, there will be one sentence : "successfully! ! ! , Press ESC to quit. "If we withdraw from the half-way by the ESC, Y coordinates of the aircr
