My First XNA Game

By Fons Sonnemans, 27-mei-2007

I finally found some time to play with XNA. I learned a lot from Rob Miles at TechEd 2006. He has some great samples on his website. Rob will also be presenting about this subject on the DevDays 2007 in the Netherlands. Fun is guaranteed.

My first game is a remake of a game I build 20 years ago on my Commodore 64. You must move around a bouncing ball using your joystick. The ball may not collide with the flying birds. It took me only a few hours to build and it was great fun.

More Avalon/XAML Minesweeper samples

By Fons Sonnemans, 01-okt-2005

I have found two more Avalon Minesweeper implementations.

BTW I plan to post the sourcecode of my implementation soon. I have to clean it up first.


C# Minesweeper Game

By Fons Sonnemans, 29-jun-2003



I have always wondered how hard it would be to write a game in C#. I picked Minesweeper for my first try. Made an OO design and then went programming.

See the result in the downloadable zip file. The whole program is less then 400 lines of code!


I have reduced the complexity a bit by eliminating the flag-icon and all menu options.


The application is build using 3 objects: a Form, a Game which holds an array of Square objects.

UML Class Diagram (Visio)

MinewsweeperForm class
This class creates a Game object when the Start button is clicked. It also updates the Timer and Mines display. It contains a Panel control in which the Game object generates the Squares.

Game class
This class contains a multidimensional array of Square objects which is initialized in the constructor. The mines are randomly placed in the squares. It has a Timer which is used to calculate the elapsed gametime. The events DismantledMinesChanged and Tick are used to notify the MinesweeperForm that is has to update the GUI.

Square class
This class contains a normal WinForm Button object which Click and MouseDown events are captured. These events trigger the real game logic. The number of surrounding mines is calculated (cascading). Mines are dismantled (marked) or explode which is reported to the Game object using events.


Writing the Minesweeper game was a lot of fun. It demonstrates how object orientation really makes it easy. Examine it by stepping trough the code using the VS.NET debugger. I hope you enjoyed this article and sample.
