-Developed flappy bird game using javascprit allow users using easliy space and click complished the bird fly
- Implements movement of objects (sky, land, bird, pipes) using some Physical knowledge and mathematical formulas
-Realize the visualization of the game using canvas technology
-Using an object-oriented approach, where concrete objects are created using constructors, and methods are put into the original object of the constructor.
-Added some technical optimizations where the bird will click, fly up, or sprint down as it goes up and down
-Utilized : JavaScript,Canvas,WebStorm for IDE

难点:
小鸟对象 (哪张小鸟图片,小鸟在哪)
而这只鸟其实是根本不会飞的……所以玩家每点击一下小鸟就会飞高一点,不点击就会下降,玩家必须控制节奏,拿捏点击屏幕的时间点
1.小鸟煽动翅膀 :每隔一个很小的时间单位更新鸟的图片 (一共三种)
2.小鸟的下落 : 其实是不停的刷新小鸟在坐标轴上y的位置,而x的位置是不变的
3.小鸟的旋转:低头飞翔 加速冲刺
管道的绘制
1.管道有上下两个柱子,中间间隔150.
(x,this.r-420)是上面柱子的左上角坐标 柱子高度420 ( x,this.r+150) 是下面柱子的左上角坐标
