When the program starts, the values of byte data members are automatically set to 0 and the background color is set to black. If you run a program with the preceding Draw method, you see that the screen just goes black. What you now need to do is take control of the update process and make the colors change over time. When an empty project is created, XNA Game Studio creates a bare-bones Update method that contains a TODO reminding the programmer to add the required code:

The Update method is rather similar to Draw but has an extra couple of statements in it, one of which starts with the word if. This is the part of the code that decides when the game

should end. When you ran your program, you may have noticed that pressing the Back button on the gamepad or on your Windows Phone stops the game. These two statements are the ones that dictate that behavior. The first statement says, If the Back button on the gamepad for player 1 (or the Back button on the phone) is pressed, do the next statement, and the second statement says, Exit the program. Put those together, and you get a behavior that means that when the Update method is called, if the Back button is pressed, the program exits. You are going to spend some time on conditions later, but for now, just remember that if you delete these two lines from your program, it is impossible to stop it via the Xbox gamepad. So don t delete them. You may be wondering who calls Update and how often. The answers at the moment are the XNA engine and 60 times a second. Whenever your game is active, it needs to update the game world. This has to happen repeatedly for a game to be any fun. The XNA engine calls the Update method to give it a chance to perform. In a full-blown game, this involves reading the gamepad, moving all the objects in the game world, checking to see if any have collided, and so on. In the mood light, the Update method just changes the color values that Draw uses to draw the display. To start with, you are just going to make a mood light that gets steadily brighter over time, so the Update method increases the value of the red, green, and blue intensities by one each time that it is called:

The Update method works by using the ++ operator. An operator is something in the program that tells the compiler that you want to perform an operation on a particular item. In this case, you are using the operator ++ on each of the intensity variables. The item that an operator works on is called an operand. Sometimes operators work by combining operands, and sometimes they work on a single operand. The ++ operator works only on a single operand. The Update method uses it on each color in turn so that each color intensity increases by one. This means that each time the Update method is called, the display should get a little bit brighter.

If you run the program with this Update method, you see that the display does get steadily brighter for about four seconds. Then it goes black again. This does not seem right. One of the additions seems to be making the value much smaller rather than increasing it. To understand why this is, you need to take a look at how numbers are stored in computers.
