c# - 操纵杆 + c# : Analog button

Question

我正在使用 Microsoft DirectX 访问我的游戏 handle 。这是一个像这样的 USB 游戏 handle :

我可以知道何时按下按钮以及轴的模拟值...

问题是是否有办法知道何时按下模拟按钮(红灯亮起)。

这可能吗？如何？

Answer 1

我会推荐 SlimDX或 SharpDX为您的项目。它们支持 DirectX API，而且非常简单。

SlimDX:

using SlimDX.DirectInput;

创建一个新的 DirectInput 对象:

DirectInput input = new DirectInput();

然后是用于处理的 GameController 类:

public class GameController
{
    private Joystick joystick;
    private JoystickState state = new JoystickState();
}

然后像这样使用它:

public GameController(DirectInput directInput, Game game, int number)
{
    // Search for Device
    var devices = directInput.GetDevices(DeviceClass.GameController, DeviceEnumerationFlags.AttachedOnly);
    if (devices.Count == 0 || devices[number] == null)
    {
        // No Device
        return;
    }

    // Create Gamepad
    joystick = new Joystick(directInput, devices[number].InstanceGuid);  
    joystick.SetCooperativeLevel(game.Window.Handle, CooperativeLevel.Exclusive | CooperativeLevel.Foreground);

    // Set Axis Range for the Analog Sticks between -1000 and 1000 
    foreach (DeviceObjectInstance deviceObject in joystick.GetObjects())
    {
        if ((deviceObject.ObjectType & ObjectDeviceType.Axis) != 0)
            joystick.GetObjectPropertiesById((int)deviceObject.ObjectType).SetRange(-1000, 1000);
    }
    joystick.Acquire();
}

最后得到每个方法的状态:

public JoystickState GetState()
{
    if (joystick.Acquire().IsFailure || joystick.Poll().IsFailure)
    {
        state = new JoystickState();
        return state;
    }

    state = joystick.GetCurrentState();

    return state;
}
