}
Then the code using the
Vector2
would look like this:
Vector2
v =
new
Vector
();
v.X = 10;
// Automatically calls get property on X
The neat thing about a property is it follows the syntax of a normal variable, even
though it secretly isn't one. There are quite a few other unique features in C#, as

going through the code, if you find yourself struggling with C#-isms, you can find
many references online for learning C# coming from a C++ or Java background.

popular is the indie game
Bastion
, which launched on the Xbox 360 in 2011.
I personally think XNA is a great framework for first learning how to program
games (especially 3D ones). It handles the more tedious aspects of programming
a game—such as creating a window, initializing the graphics library, and most im-
