C# Tutorial 8
In this part of my C# tutorial series we will make a fun little game. I’m going to show how to create 2 warriors that will fight to the death in a simulated battle. More complex video games follow many of the techniques we cover in this video. It also will show how awesome object oriented programming is in that it gives you the ability to model just about any real world object, or interaction.
For best results print the code and then write your own programs while referring to the cheat sheet.
