22. Games I Made with C#: Ropossum, Next, iNversion

23. Ropossum
http://www.mohammadshaker.com/ropossum.html

24. Ropossumis an authoring tool for procedurally generating playable levels for physics-based games (Cut the Rope as a test case.) It allows the creation of content, editing, and realtimeinteraction with the system to provide immediate feedback on the level design. It’s both for players and designers.

27. “There is no programming language
-no matter how structured–that will prevent programmers from making bad programs.”
Programming languages
(Larry Flon)

28. “If debugging is the process of removing bugs, then programming must be the process of putting them in.”
Programming languages
(EdsgerW. Dijkstra)

29. New Technique!

30. So, Learn C# or not?

31. Let’s Go C#ing!

32. .NET 3.0.NET 3.5.NET 4.0.NET 4.5

33. Visual Studio 2008201020122013

34. How is a C++ ?

35. C# introIt’s a fully OOP language! Everything is an object!

36. Everything is an object!
Object
Integer
String
…
Car
Meal
Enemy

37. Object
Integer
String
…
Car
Meal
Enemy
Everything is an object!
InC#.NETeverything(evenyourclasses)willdirectlyinheritfromclassobject.ThisisessentialforMemoryManagementandGarbageCollection.

38. An Objector a Class?

A ?? B means A!= null ? A : B

223. Concepts You Should Know

224. A Look Inside the MemoryStackand Heap

225. Stackand Heap
•The Stack
–is where normal variables are stored (likeints, anddoubles)
–All of the variables inside of a method are placed on the stack as well.
•The Heap
–It is just put in a big pile, hence the "heap" name!
–Objects (classes instances) are stored in the heap.
•In order to keep track of your object, a "reference" is used and placed on the stack. So the bulk of the object's information lives in the heap, while you get to keep track of a reference to it on the stack.

226. Boxing and Unboxinglike Java?

227. Boxing and Unboxing
•Boxing: the following assignment wraps up the value 3 into a heap object
object obj= 3;
•Unboxing: the following assignment unwraps the value again
intx = (int) obj;
3
obj
