Question

when running my game (snake) I am suppose to be able to move the snake around the form using the keys w,a,s and d. (atm I have only written the code for left and right movement just has a jumping off point). However, when running the program nothing happens. I have tried using break points, however, it seems as if my program isn’t even reading the keypress method, even though I am pressing keys.

Here is the Move method in the snake class.

public void Move(int pixels)
{
    if (pixels < 0)
    {
        xPosition_ = xPosition_ -= SNAKE_WIDTH;
    }
    else if (pixels > 0)
    {
        xPosition_ = xPosition_ += SNAKE_WIDTH;
    }
}

And here is the keypress method.

private void GameScreen_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == 'a')
    {
        snake.Move(-1);
    }
    if (e.KeyChar == 'd')
    {
        snake.Move(1);
    }
    this.Refresh();
}

the graphics get drawn fine to the pictureBox control.

Thanks in advance.

Do you have the KeyPreview set to true on the form?
