操纵杆+ c＃：模拟按钮

Question

我正在使用Microsoft DirectX访问我的手柄。这是一个USB游戏手柄像这样的：

我能得到访问时，按下按钮，并在轴的模拟值就知道...

的事情是，如果有一个方法知道何时按下模拟按钮（红灯亮）。

这可能吗？怎么样？

Answer 1

我会为您的项目推荐SlimDX或SharpDX。他们支持DirectX API并且非常简单。

SlimDX：

using SlimDX.DirectInput; 

创建一个新的DirectInput-对象：

DirectInput input = new DirectInput(); 

然后，GameController类处理：

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

而且使用它像这样：

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(); 
} 

每个方法最终得到了国家：

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

    state = joystick.GetCurrentState(); 

    return state; 
}
