How to slow down or stop key presses in XNA

Question

I\'ve begun writing a game using XNA Framework and have hit some simple problem I do not know how to solve correctly.

I\'m displaying a menu using Texture2D and using th

Answer 1

I thought the previous answers were a bit over-complicated, so I'm giving this one here...

Copy the KeyPress class below in a new file, declare the KeyPress variables, initialize them in your Initialize() method. From there you can do if ([yourkey].IsPressed()) ...

Note: this answer works only for Keyboard input, but it should be easily ported to Gamepad or any other input. I think keeping the code for the different types of input separate is better.

public class KeyPress
{
    public KeyPress(Keys Key)
    {
        key = Key;
        isHeld = false;
    }

    public bool IsPressed { get { return isPressed(); } }

    public static void Update() { state = Keyboard.GetState(); }

    private Keys key;
    private bool isHeld;
    private static KeyboardState state;
    private bool isPressed()
    {
        if (state.IsKeyDown(key))
        {
            if (isHeld) return false;
            else
            {
                isHeld = true;
                return true;
            }
        }
        else
        {
            if (isHeld) isHeld = false;
            return false;
        }
    }
}

Usage:

// Declare variable
KeyPress escape;

// Initialize()
escape = new KeyPress(Keys.Escape)

// Update()
KeyPress.Update();
if (escape.IsPressed())
    ...

I might be wrong, but I think my answer is easier on resources than the accepted answer and also more readable!
