Goals:



1. Obtain the example code

Download and unzip the zip file and you will see an ExampleProgram folder. Open the ExampleProgram folder, the EXE folder contains the compiled program and you can double click on the .sln file to work with the source code.

When the game starts, you'll see a screen that looks similar to this:


This version of the 'zap' game looks and plays identically to the prior version, which was explained in the 335 tutorial .  The only visible change is that instead of having a single, continuous beam that the player uses to try and zap the enemy, there is now a line of distinct dots, as pictured above.


2. Examining The Program:

Let's examine the C# source code that produces the behavior we see on-screen
