  1. Introduction to Jam’sVideo Game Package CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  2. The Plan • Scope of Video Game Package • Basic Design of the Video Game Package • Steps to making a game • How the Pong was made • Limitations of the Video Game Package CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  3. Scope of the Video Game Package • Goals of Jam’s Video Game Package • Simple to use • Reasonably fast • Designed to be examined and modified for academic purposes in computer science courses • What Jam’s package is not designed for • High speed animation/user input • Scripting games • Complex games CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  4. JFrame Or Applet GameLoop Animation Canvas Mouse Keyboard Sprite Sprite Sprite Tracker Tracker Tracker Basic Design of theVideo Game Package CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  5. Basic Design of theVideo Game Package Tracker The Tracker is what Makes the BallSprite move CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  6. Basic Design of theVideo Game Package • Point2D.Double getLocation() • double getScaleFactor() • double getRotationAddition() • void advanceTime() Tracker CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  7. Sprite Tracker Basic Design of theVideo Game Package CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  8. Sprite Tracker Basic Design of theVideo Game Package Has instance variables, and mutator and accessor methods for: • Shape • Location • Size • Rotation • Color CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  9. Animation Canvas Sprite Sprite Sprite Tracker Tracker Tracker Basic Design of theVideo Game Package CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  10. Animation Canvas Sprite Sprite Sprite Tracker Tracker Tracker Basic Design of theVideo Game Package AnimationCanvasis a JPanel • with a collection of Sprites • that paints itself by painting all of its Sprites CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  11. GameLoop Animation Canvas Mouse Keyboard Sprite Sprite Sprite Tracker Tracker Tracker Basic Design of theVideo Game Package GameLoop adds: • animation • interaction via • Keyboard • Mouse CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  12. Basic Design of theVideo Game Package JFrame or Applet used to: • Put the game on the screen • Start the game • Provide game control JFrame Or Applet CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  13. JFrame Or Applet GameLoop Animation Canvas Mouse Keyboard Sprite Sprite Sprite Tracker Tracker Tracker Basic Design of theVideo Game Package CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  14. Steps to Making a Game • Extend GameLoop.java • In Constructor • Make Sprites • Make Trackers • Attach Trackers to Sprites • Add Sprites to AnimationCanvas • In advanceFrame provide game logic • Make a JFrame or Applet • Add extended GameLoop to JFrame or Applet • setFrameRate to start the game CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  15. JFrame Or Applet GameLoop Animation Canvas Mouse Keyboard Sprite Sprite Sprite Tracker Tracker Tracker Basic Design of theVideo Game Package • Extend GameLoop.java • In Constructor • Make Sprites • Make Trackers • Attach Trackers to Sprites • Add Sprites to AnimationCanvas • In advanceFrame provide game logic • Make a JFrame or Applet • Add extended GameLoop to JFrame or Applet • setFrameRate to start the game CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  16. How Pong was Made • BallSprite was written to extend Sprite • WallSprite was written to extend Sprite • ProjectileTracker was written to implement a Tracker • PongLoop was written to extend GameLoop • Pong was written to use PongLoop CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  17. How Pong was Made Some of the more complex parts of Pong that we’ll talk about in more detail later: • Loops • Conditionals • Event handling • Inheritance & Interfaces • Collections • Collision detection CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  18. How Pong was Made What you will need to know shortly: • Basic classes in the package • Basic structure of the package • Basic steps to making the game • General idea about how Pong.java and PongLoop.java work • Enough familiarity to make minor modifications to BallSprite and PongLoop CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  19. How Pong was Made What you don’t need to understand yet: • All of the classes in the package • All of the code in the basic classes • How to make your own classes like Pong and PongLoop from scratch CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  20. How Pong was Made What you’ll be doing in the next homework: (in addition to problems from Big Java) • Altering BallSprite • Altering ProjectileTracker …and it will be fun (when it works) CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html

  21. How Pong was Made Let’s take a look at two classes: • Open up a web browser • Go to the course website and download pong.jar to the desktop (from code link) • Open up Eclipse • Import pong.jar • Look in tipgame for BallSprite.java • Look in tipgame for ProjectileTracker.java CPS4: Java for Video Games http://www.cs.duke.edu/education/courses/spring04/cps004/calendar.html
