使用C#開發Joystick搖桿應用程式

開發平台：VS2010 + .NET Framework 4.0

1. 下載 DirectX SDK

2. 建立Windows Form Application

3. References中加入Microsoft.DirectX.DirectInput.dll

    (C:\Windows\Microsoft.NET\DirectX for Managed Code\1.0.2902.0\Microsoft.DirectX.DirectInput.dll)

4. 程式撰寫

using Microsoft.DirectX.DirectInput;

private void InitDevices()

{

    foreach ( DeviceInstance di in Manager.GetDevices(DeviceClass.GameControl, EnumDevicesFlags.AttachedOnly))

       joystick = new Device(di.InstanceGuid);

       break;

   }

   if (joystick == null)

   {

       //Throw exception if joystick not found.

       throw new Exception("No joystick found.");

}

private void ConfigureDevice()

{

   //Set joystick axis ranges.

   foreach (DeviceObjectInstance doi in joystick.Objects)

   {

       if ((doi.ObjectId & (int)DeviceObjectTypeFlags.Axis) != 0)

       {

           joystick.Properties.SetRange(ParameterHow.ById, doi.ObjectId, new InputRange(-1000, 1000));

       }

   }

   //Set joystick axis mode absolute.

   joystick.Properties.AxisModeAbsolute = true;

   //set cooperative level.

   joystick.SetCooperativeLevel(this, CooperativeLevelFlags.NonExclusive | CooperativeLevelFlags.Background);

   joystick.Acquire();

}

//Get Joystick State.

JoystickState state = joystick.CurrentJoystickState;

//Capture Buttons.

byte[] buttons = state.GetButtons();

for (int i = 0; i < buttons.Length; i++)

{

   if (buttons[i] != 0)

   {

      //your code here

   }

}

//Point of View

int[] POV = state.GetPointOfView();

//Slider

int[] Slider = state.GetSlider();

LoaderLock例外狀況

Debug -> Exceptions -> Managed Debugging Assistants -> LoaderLock Thrown選項取消

.NET Framework例外狀況，修改app.config
