我们平常玩的飞机射击类游戏，这其实很简单，在加载上图片后，实现精灵类碰撞检测，每按键一次，图片显示相应的动作，真的很简单，希望你能从这个简单的游戏获得启发-To play our usual type of plane shooting games, this is a very simple add-on in the picture, the type of collision detection Elven implementation, each button once, the motion picture shows, really easy, I hope you benefit from this simple game get inspired

平滑文字滚动示例 这个文字滚动控件比较不错，滚动比较平滑，没有闪烁现象，支持左右水平、上下垂直滚动。【向左滚动样式一】是循环连续滚动，【向左滚动样式二】则滚动到左端时停止一下继续滚动，【向上滚动样式一】也和前面差不多。-Smooth text scrolling text scrolling control sample in this comparison is true that relatively smooth rolling, no flicker phenomenon, about the level of support, up and down vertical scrolling. [1] style scroll to the left is the cycle of continuous rolling, rolling left style [2] then scroll to the left when you cease to continue rolling, rolling upward [Style] also in front of an almost.

Polygon clipping is one of those humble tasks computers do all the time. It s a basic operation in creating graphic output of all kinds. There are several well-known polygon clipping algorithms, each having its strengths and weaknesses. The oldest one (from 1974) is called the Sutherland-Hodgman algorithm. In its basic form, it is relatively simple. It is also very efficient in two important cases, one being when the polygon is completely inside the boundaries, and the other when it s completely outside.
