#上个月为了推广游戏花2天半搞的一个，算是第一次接触伪3D，自己想的公式，所以玩起来还会有些奇怪现象（有些敌机越追越近，有些则越远）。当时只用过一次就不用了，现在觉得扔了浪费，就先上传当一个小项目，不知未来能进化到什么程度…其实是想做成伪3D空间引擎，并不是away3d那样，而是更倾向于易用和展现。

待处理
@优化代码，模块化。
@容易找不到最后一架敌机。
@相对移动速度有错误。
@敌机坐标可显示（雷达）
@攻击时射击轨迹计算（远近规律、移动中抛物线规律）
@副武器可用。
@敌人会进行攻击。
@空间角度及距离计算要精确。
@使用AS3编写，学习Point3D类。
@流畅度优先
@游戏基本说明
@生命槽,不知道怎么死
@鼠标的上移和你的飞行速度挂钩
@连击系统,你在一定时间内 连续的击破敌机可以获得比单独击破一架获得更高的分数
@积分系统,用这些积分 还可以变成游戏中的金钱 购买和升级武器,飞机的生命槽 推进器 武器威力 装填时间 冷却时间,都会消耗大量的积分.
@购买武器
