Thanks for the awesome year guys!

Enjoy your summer!

Jump Code

// Up top

bool jump = false;

bool falling = false;

bool ready = true;

// In Update

if (keystate.IsKeyDown(Keys.Space) && oldKeyState.IsKeyUp(Keys.Space) && !jump && ready)

{

jump = true;

ready = false;

velocity = new Vector2(0f, -5f);

playerPos.Y--;

}

if (jump)

{

if (playerPos.Y <>

2 Scrolling BG's

if (playerPos.X > 400)

2D Side-Scroller Tutorial

Creator's Club Site Tutorials

Our assignment today is to read, follow, and reproduce THIS TUTORIAL

Aim for a level of mastery such that you can reapply the methods used in your own game.

.

Sprite Sheet Adaptations

After the review session, we're going to implement the code from yesterday:

• This is where I borrowed the project
• Add the animation effect to either Pong or Raining Triangles of Death.
• The addition should make sense and add effect to your game.
• You have the entire class to make your additions.
• You are working by yourself.
• You can do this.
• I will not be looking at your code whilst answering your questions.

.

Retest

Your retest is the following:

• Make the screen Yellow.
• Draw a (200px by 200px) graphic in the exact center of the screen.
• Make the graphic move up if the "W" key is pressed, move right if the "D" key is pressed, move down if the "S" key is pressed, and move left if the "A" key is pressed.
• If the sprite touches a wall, play a wav file.

When you're done, zip and email me your project folder to howardm@cantonlocal.org

.

XNA Tutorials

Lets take a step back... I figured we'd need this after Friday's test...

We're gonna use the tutorials from this site to help us out: XNADEVELOPMENT.COM

.

XNA Test

Your first XNA test is a practical. You must complete the following:

• The window background should be black
• Draw the following 2 sprites side-by-side on the screen: SPRITE1 & SPRITE2
• Move SPRITE1 either up, down, left or right with the arrow keys. Move SPRITE2 either up, down, left, or right with the SPACE BAR and the arrow keys pressed.
• Play the any WAV file when the "W" key is pressed.

.

Pong-a-thon

Let me see the Poooo-ooo-ooong. Let me see that ponnnngy pong pong pong pong.

In a comment to this post, describe what additions/ edits you'll be making to your pong game. The additions should be attainable by midway through class Friday.

.

XNA Intro Quiz

A few questions:

• What is the programming language used by XNA?
• What is the name of the file where the XNA main logic loop resides?
• In which method/ function is media content loaded?
• On an image, where is point (0, 0) ?

Mum, Dad, I Want to be a Game Designer

Today, we're watching a presentation from this cheeky fellow from EA Games.

Click here for the YouTube link

As a response to the video, answer the following:

1. What company does the speaker represent?
2. What is the most important quality of a game design?
3. Describe some of the qualities associated with a game's hero.
4. How would you characterize the trends in video games during the past 10 years.
5. List 6 game console units.
6. What's your favorite game? Why?
7. What's your least favorite game? Why?

Module 5 - "Fun"ctions

1) What are the main differences between local and global variables?

2) Can a local variable be declared anywhere within a block?

3) Does a local variable hold its value between calls to the function in which it is declared?

Create a function called hypot( ) that computes the length of the hypotenuse of a right triangle given the lengths of the two opposing sides. Demonstrate its use in a program. For this problem, you will need to use the sqrt( ) standard library function, which returns the square root of its argument.

It has this prototype:

double sqrt(double val);

It uses the header cmath

Module 5 - "Fun"ctions

Read Module 5!

Answer the following 2 Critical Checks:

1. When a function is called, what happens to program execution?

2. What is the difference between an argument and a parameter?

3. If a function requires a parameter, where is it declared?

1. Show the two forms of the return statement.

2. Can a void function return a value?

3. Can a function call be part of an expression?

4. What is a null-terminated string?

6. When using strcat( ), how large must the recipient array be?

7. In a multidimensional array, how is each index specified?

8. Show how to initialize an int array called nums with the values 5, 66, and 88.

9. What is the principal advantage of an unsized array declaration?

10. What is a pointer? What are the two pointer operators?

11. Can a pointer be indexed like an array? Can an array be accessed through a pointer?

13. What is it called when one pointer points to another pointer?

14. Of what significance is a null pointer in C++?

Group Work

Please write me 2 paragraphs concerning the group work:

1. Describe your contributions to the group work we've been doing during this past work. Do not tell me what the other group members did, tell me what you did.
2. Tell me what you plan on doing if I give you 3 more class periods to finish up the group work. Project "oversight" is not acceptable. Nobody should be "helping" a group member do something, we should all have our own roles and duties. If you need direction, ask a group member, or ask me.
