Unity接入罗技G29方向盘，通过SDK获取按键信息
说明：
??最近需要做一个外设汽车驾驶相关的软件，采用的外设 罗技G29方向盘，项目中遇到的问题这里记录一下。
项目准备：
??1.下载罗技的SDK
??2.下载罗技游戏软件
??3.Unity商店中导入Logitech Gaming SDK
遇到的问题：
??1.Unity商店中导入的SDK运行会报错，将项目准备中步骤一下载的SDK 路径：Lib\x64\LogitechSteeringWheelLib.lib 复制到Logitech SDK文件夹下
??2.插件没有问题，运行并不能获取方向盘的按键信息，这个情况我的电脑重启了好多次，也补充了一些基础的运行环境，一直就是获取不到方向盘的按键信息，最后我重装了一下罗技游戏软件，重启运行发现可以用了。
最后：
??将插件中的LogitechSteeringWheel.cs脚本挂载到场景中运行：
相关方向盘和脚踏板的监听代码（我这没有挡位外设）
