 NoName-GamePad Project gamepad1 The complete Code of Game1.cs The complete Code of Form1.cs |
|
|
There is just one generic gamepad support by XNA: the wired USB XBox 360 Controller from Microsoft. Price: ca. 30 €. A talented german hacker "SoopahMan" wrote a Soopah.XNA.Input.dll based on DirectX.DirectInput that allows the use of nearly any other USB-GamePad. Plug it into an USB-Port and check it: Start → Control Panel → Game Controllers → If more than one controller is listed, the following project gamepad1 will just recognize the first of them. Problem: The controllers can be very different: arrangement of buttons, no. of analog thumb sticks. Our program arranges the buttons in a technical, not in a logical order. |

Replace the existing lines of Form1.cs by the following code:

Click Debug → Start Debugging F5.
If an exception occurs in game.Run(); check the Error List.
Probably there will be this warning: Found conflicts between different versions of the same dependent assembly.
Double click the warning. A Microsoft Visual Studio message box appears and asks: Do you want to fix these conflicts by adding binding redirect records in the app.config file ?. Quit by pressing Yes. An app.config item appears within the Solution Explorer-branch gamepad1 and solves the problem.
