01:介绍

一天，小编没事干，想做一个游戏，于是参考了大量内容，制作了这个飞行模拟器。

02:资源

02.01:准备

1、python
python IDLE (3.7 32-bit)
其他版本没有太大影响

2、panda3d（python库）
pip安装方法

pip3 install panda3d

02.02:参考

1、panda3d
panda3d官网
谷歌翻译

2、三角学
大学数学-平面三角学.pdf

03:上代码

可全屏

玩法：
鼠标向上往下飞
鼠标向下往下飞
鼠标往左往左转
鼠标往右往右转
碰到地面会退出

如果您想鼠标往上往上飞，请将第92行改成：

        (mx0,my0)=(size[0]-mouse.getX(),size[1]-mouse.getY())

1、感兴趣的网友可以给这个程序化简一下，或者加上物理效应
2、感兴趣的网友可以找我要一下详细过程
