Developing Flood Control using XNA Game Development

by Kurt Jaegers | December 2011 | Beginner's Guides

While playable, Flood Control in its current form is rather rough. When the player clicks on game pieces, they simply flop to their new orientation. Completed rows vanish without a trace, being filled in so rapidly that it is hard to tell if they actually disappeared at all. The game never ends! Once you have started, you can play forever, not worrying about the underwater research lab actually filling up with water.

In this article,by Kurt Jaegars,author of XNA 4.0 Game Development by Example: Beginner's Guide – Visual Basic Edition we will address these issues by:

  • Animating the rotation of pieces, when manipulated by the player
  • Gradually fading out pieces of completed scoring chains
  • Animating the falling of pieces into place on the board
  • Implementing the flooding of the dome and adding increasing difficulty levels
  • Adding a SpriteFont to the game, and displaying the current level and score in their appropriate positions on the screen

All of these enhancements will give the player a better game experience, as well as give us the opportunity to learn more about how the SpriteBatch class can be used for animation and text display.
