调用：

private bool StartJoystickObj(string Name)
{
try

_joystickOBJ = new JoystickObj(Name);
_joystickOBJ.Connect();
_joystickOBJ.JoystickConnectEvent += _joystickOBJ_JoystickConnectEvent;

_joystickOBJ.JoystickButtonEvent += _joystickOBJ_JoystickButtonEvent;
GetInitData();
}
catch (Exception ex)
{
Logger.Error(ex.ToString());
}
return false;
}在其他主类中启动：StartJoystickObj(PublicStaticVariables.JoystickName);
private void _joystickOBJ_JoystickMoveEvent(int JoyX, int JoyY)
{
try
{
if (JoyX < 0) { }
if (JoyX > 0) { }
if (JoyY < 0) { }
if (JoyY > 0) { }
}
catch (Exception ex)
{
}
}
private void _joystickOBJ_JoystickButtonEvent(int KeyNum)
{
try
{
//根据具体键值来写操作逻辑
if (KeyNum > 0 && KeyNum < 10)
{

//设置控制方式
if (KeyNum == 16)
{
if (JoystickFunState == 0)
{

}
else

}
}
//设置控制类型
if (KeyNum == 13 && _isStickInZero)

}
//
if (KeyNum == 12)

//复位一些状态
