I made a game named "Spaceship Invaders" in C#. For the ship movements, i wrote some code (at KeyDown Form event) but, it not so efficient.

For example: If I press Left key and Up key, at the same time, and I keep pressing, the KeyDown event will take the first key pressed(it's impossible to press 2 keys at the same time).

switch (e.KeyCode)
{
    case Keys.Left:
        if(SHIP.Location.X - move_LEFT >= 0)
            SHIP.Location = new Point(SHIP.Location.X - move_LEFT, SHIP.Location.Y);
        if (using_mouse)
            Cursor.Position = SHIP.Location;
        break;

    case Keys.Up:
        if(SHIP.Location.Y - move_UP >= 0)
            SHIP.Location = new Point(SHIP.Location.X, SHIP.Location.Y - move_UP);
        if (using_mouse)
            Cursor.Position = SHIP.Location;
        break;
}

Where move_UP and move_Left are variables int.

protected int move_LEFT = 40;
protected int move_UP = 40;

How can i fix this?

You should probably look at a game library like DirectX or XNA. – PC Luddite Jul 03 '15 at 15:10
Whilst you're working on this, be aware that [most keyboards are physically incapable](http://pcbheaven.com/wikipages/How_Key_Matrices_Works/) of registering key combinations of certain keys. – James Thorpe Jul 03 '15 at 15:11
Can you tell me how to make with DirectX, please? – Cristian Jul 03 '15 at 15:20
@VoiculescuCristianConstantin Google it. You'll find something. – PC Luddite Jul 04 '15 at 15:57
