  12. Assessment • coursework 50% • examination 50%

  13. Why not Flash? • Flash is excellent for small games • Flash is good for Internet games • No serious big game is written in Flash • Large-scale project need professional approach to programming, not just a scripting • C++ • Java

  14. Games in Java? Java in Games? • Java is too slow for games programming • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming

  15. Games in Java? Java in Games? • Java is too slow for games programming • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming MYTHS

  16. Games in Java? Java in Games? • Java is too slow for games programming • True in 1996. • JDK 1.0 was 20 – 40 times slower than C++ • J2SE 5.0 is typically 1.1 times slower • Bottleneck is somewhere else (3D hardware, the net) • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles

  17. Games in Java? Java in Games? • Java is too slow for games programming • Java has memory leaks • garbage collection • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming

  18. Games in Java? Java in Games? • Java is too slow for games programming • Java has memory leaks • Java is too high-level • J2SE 1.4: full-screen exclusive mode (FSEM) • JNI: Java Native Interface • JInput: Game Controller API • until DOOM it was C/C++ what was considered too high level • Java application instalation is a nightmare • Java isn’t supported on games consoles

  19. Games in Java? Java in Games? • Java is too slow for games programming • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • just use a good installation software (install4j) • code bloat (eg. JRE = 15 MB) but... which of modern games is less than, say, 600MB? • Java isn’t supported on games consoles • No one uses Java to write real games

  20. Games in Java? Java in Games? • Java is too slow for games programming • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles • well, this one is (still) true... • rumours on porting JVM to PS2 – nothing released • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming

  21. Games in Java? Java in Games? Puzzle Pirates Chrome Law and Order II Kingdom of Wars Alien Flux Runescape Star Wars Galaxies • Java is too slow for games programming • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming

  22. Games in Java? Java in Games? MOBILE GAMES • Java is too slow for games programming • Java has memory leaks • Java is too high-level • Java application instalation is a nightmare • Java isn’t supported on games consoles • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming

  23. Games in Java? Java in Games? • Java isn’t supported on games consoles • No one uses Java to write real games • Sun isn’t interested in supporting Java gaming • full-scren mode • faster I/O, memory mapping • nanosecond timers (v. 5.0) • Java 3D • Java Media Framework • Java Communications API • Java Games Profile

  24. Why not C++? • Java is better for education • CISM policy anyway you are strongly advised to learn C++ which is widely used in industry • C++ • On-line Games • Java

  25. Why not C++? • Java is better for education • CISM policy anyway you are strongly advised to learn C++ which is widely used in industry • C++ • On-line Games • Java fortunately, I don’t have to answer this question now...

  26. Why Mathematics? • Geometry – a tool for drawing graphical elements in 2D and 3D • Calculations make the player experience more life-like eg. rules of perspective 3D animation

  27. Why Physics? fall down accelerate hit go throw break fly ride rotate dig swim shoot aim strike bounce drive catch explode reflect jump run kick sail

  28. Outline • Introductory Lecture (this one) • C++ Basics: Introducing Your Game Engine • Maths Basics • Thales Theorem and Perspective in 3D • Roll and Fall: Playing with the Laws of Motion • Collisions, Momentum and Energy • Resistance and Mechanics of Cars • Explosions • Physics Engine • Physics of Rotational Motion

  29. Demo: Applying Physics to Helicopter
