  1. GameDev Intro Engineering Principles Game Development & Special topics in Computer Science

  2. Introduction to Engineering • Description • Objective • Meeting times • Assessment • Lab access • Questions?

  3. Introduction • This engineering course will consist of two tracts: • The Computer Science tract will emphasize software engineering principles, along with analysis and design. • The Civil Engineering tract will focus on the consideration of Seismic activity and how it relates to society.

  4. Objective • You will learn what a computer game is and how it is made. • We will walked through an introduction of the C# language and XNA. • A simple game engine will emerge from the completion of numerous “short” programming assignments • Create a simple game, using both 2D and 3D rendering, user input, audio, physics, the works.

  5. Meeting • Time: Tuesdays 8:00am - 11:50am • Location: NC 2409 • Instructor: Mack Gammeter • Email: mack@gammeter.com • Website: http://www.gammeter.com/SummerEngineering/

  6. What to bring / Textbook • Please Bring: • Notebook • USB Flash drive • Textbook: Not Required • Laptop: Not Required, but Preferred • Handouts: • All lectures will be available online. • You are welcome to follow along online or print them out, if you happen to have an over developed animosity toward wooded life-forms…

  7. Assessment • Assignments: Homework will be started in class, completed at home, and due in a week. • Exams: In-class mid term and final exams will be unified (i.e., just on for both) for Software and Civil Engineer • Grading: Students will be graded based on assignments, exams, a class project, and class participation, initiative. • Attendance: Mandatory. Missing class is way bad, bad, bad…

  8. Computer Lab • Computer laboratory: • No smoking (really?), eating, drinking or cell phone • Be respectful with technology – during lectures, don’t be on You-Tube or twitter or your very first my space account. • Student account lab login: • Username: onedaytemp • Password: spApRap65!Ne

  9. Some questions ? • Q: Will we be creating games in this course? • We will try. We will build the pieces for a game. • Whether we build a game has to do with your tenacity, enthusiasm, and effort. • Q: Is this course about creating games? • For the most part yes. We will also discuss about the game business, the socioeconomically impact of computer/video games and etc…. • This course is mainly about learning principles of engineering.

  43. What is a Game? (1 of 3) • Movie? (why not?) • no interaction • outcome fixed • Toy? (has interaction … why not?) • no goal, but still fun • players can develop own goals Chapter 2.2, Introduction to Game Development

  44. What is a Game (2 of 3) • A Computer Game is a Software Program • Not a board game or sports • Consider: chess vs. soccer vs. Warcraft • Ask: What do you lose? What do you gain? • Lose: 1) physical pieces, 2) social interaction • Gain: 1) real-time, 2) more immersive, 3) more complexity • A Computer Game involves Players Based on Tutorial: What is a Good Game?, by Mark Overmars

  45. What is a Game (3 of 3) • Playing a Game is About Making Decisions • What weapon to use, what resource to build • Playing a Game is About Control • Player wants to impact outcome • A Game Needs a Goal • Without game goals, a player develops his/her own (a toy) Based on Tutorial: What is a Good Game?, by Mark Overmars

  46. What a Game is Not • A bunch of cool features • Necessary, but not sufficient • A lot of fancy graphics • Game must work without fancy graphics • A series of puzzles • All games have them • An intriguing story • Good story encourages immersion • But will mean nothing without gameplay Based on Chapter 2, Game Architecture and Design, by Rollings and Morris

  47. Game Life Cycle • Concept / Experiment / Demo • Prototype • Pre-Production • Production • Testing, Tuning, Debugging • Porting & Localization

  48. Concept, Experiment, Demo • Initial idea used to help ‘sell’ the game and get things started • Might be a 5 page document, or could be a simple interactive demo written in a couple days, or could just be a couple sketches…

  49. Prototype • Initial ‘proof of concept’ • Make a demo that shows key concept or concepts • A few people for a few weeks • Might be thrown away
