最初步的模型以及算法.空格是发射,发射的具体效果没写,呵呵~~我个人觉得还有以下地方可以改:

1.飞碟的路径可以变化大些

2.飞碟出现的方向

3.每次飞碟出现后有规定子弹

4.闯关

-initial model and algorithm. Space is fired, and the launch specific effects I did not write, Ha ha ~ ~ I think there can be changes to the following areas : 1. UFO paths can change these two big. the direction of the flying saucer 3. After each flying saucer provides four bullets. slipped
