Release 2.0 (XNA V3.1)

Topic: Topic.5.RepetitionStructures
Example: Ex_8.ZapGameDoWhileLoop

Zap Game: do/while Loop



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 160 tutorial .

The only difference, code-wise, between this version and the prior version is that this version uses a do...while loop, instead of a normal while loop.

2. Examining The Program:

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


  1. Go back to the 160 tutorial, and redo those exercises, using do...while loop(s).
