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 realtime interaction with the system to provide immediate feedback on the level

design. It’s both for players and designers.

“There is no programming language-no matter how structured–that will prevent programmers from making bad programs.”

Programming languages

(Larry Flon)

“If debugging is the process of removing bugs, then programming must be the process of putting them in.”

New Technique!

So, Learn C# or not?

Let’s Go C#ing!

How is a C++ ?

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

Everything is an object!

Object

Object

Integer String … Car Meal Enemy

Everything is an object!

In C#.NET everything (even your classes) will directly inherit fromclass object. This is essential for Memory Management andGarbage Collection .

An Object or a Class?

Code fast and don’t break things

A ?? B

means

A!= null ? A : B

Concepts You Should Know

A Look Inside the MemoryStack and Heap

Stack and Heap

• The Stack

– is where normal variables are stored (like ints, and doubles)

– 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.

Boxing and Unboxinglike Java?

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

int x = (int) obj;

3

obj
