1、前言这是我的第一篇技术博客，希望能为大家提供些有用信息。概述前段时间有一项工作是通过游戏手柄控制云台，通过google 和 msdn 搞定了，在这吧就总结一下吧。问题对于手柄控制主要有以下几个问题在合适的时机获取游戏手柄的输入？一般游戏手柄都是有n 个方向键和n 个功能键控制的，要确认各个键的状态？解决方案通过 windows API 中与游戏手柄相关的函数进行控制，主要是 joystick 系统函数， 这一问题的关键点是P/Invoke 调用。优点是不需要directx 支持，缺点是调用如果要想让多个窗口接受手柄输入有点麻烦（后边会详细描述）。通过 directx 的 directx inp
2、ut ， Microsoft.DirectX.DirectInput命名空间下的类对joystick 进行了很好的封装， 在.net 中用时很方便。 优点使用方便， 缺点需要directx 支持不过这点应该不用担心，现在大部分系统安装完后应该都安装了directx 在本篇中将先介绍通过directxinput 进行控制，这篇文章有些地方借鉴了codepoject 上的文章点击这里可以看到程序最终运行效果1.获取系统中已经连接成功的游戏手柄列表，代码如下view plaincopy to clipboardprint? public static string FindJoysticks(Int
