A DOM-Based Snakes Game, Part I: A Final Word

A DOM-Based Snakes Game, Part I (8)

A Final Word

In this column we started showing you how to write another DOM-based application, the Snakes game. We showed you the architecture of the game and the relationship between the game pieces and the DOM tree. We drew the board game and explained its content. We introduced the global variables section of the code and gave you a taste of its algorithm. We went over the main script and correlated each line of code to the game's flow. In the next column we'll go over the other portions of the code, namely all its functions that are not described here. We'll learn how to code the player-program interaction. Try writing these functions yourself by next time. In this column you learned:

• How to architect the application
• How to analyze its DOM tree
• How to write the main program
• How to select the right global variables
• How to find the browser's version

We also included the game's complete listing and its zipped version as well.
