When this happens, they will be created again at the top of the screen at a random location.

Starfield: Official Launch Date Announcement. We can use an empty white sprite in combination with the TintColor parameter of the SpriteBatch.Draw() method to draw squares of any color we wish. Let’s put our Star class to use by creating a scrolling star field. The Draw() method consists of a single call to the SpriteBatch.Draw() method using third overload of the method. Since velocity is stored as the change over one second, multiplying it by the (If the game is running at 60 frames per second, the value is likely to be 1 / 60 = 0.0166 seconds) determines the distance moved over a single frame. The Update() method adds the sprite’s velocity to the sprite’s location. The Destination property builds a new Rectangle based on the star’s current screen location and the width and height of the InitialFrame.

Save the image as STAR.BMP in a temporary location. Open Microsoft Paint or your favourite image editor and create a new 2 by 2 pixel image and fill it with white. Open Xamarin Studio and create a new MonoGame Windows OpenGL Application project called TwoDimensionalStarField.
