Objective C
Objective-C is an object oriented language
Follows ANSI C style coding with methods from Smalltalk
Flexible because almost everything is done at runtime:
•Dynamic Binding
•Dynamic Typing
•Dynamic Linking
Has protocols, which work like interfaces in Java they
specify a number of methods a class must implement

C++ vs. Objective-C
C++ Objective C
Adds OOP, metaprogramming
and generic programming to C
Only adds OOP to C
Comes with a std library Has no standard library; is
dependant on other libraries
Has numerous uses Mostly used for application
building
Large and complex code for OOP Simpler way of handling classes
and objects

 Framework is focused on enabling
game developers to be successful
developing on Microsoft gaming
platforms
 provides a complete set of managed
APIs for game development
 platforms WP, Xbox 360, Zune HD,
Windows OS
FOR:
 high performance game
 rapid creation of multi-screen 2D and
3D games
 manage art assets such as models,
meshes, sprites, textures, effects,
terrains, or animations in the XNA
Content Pipeline

Developing
 .NET
 XNA 4.0, Silverlight
 Microsoft Visual Studio 2010

Developing
