32. Disciplines  Game Physics Programmer  AI Programmer  Graphics Programmer  Sound Programmer  UI Programmer  Input Programmer  Network Programmer  Game Tools Programmer  Porting Programmer  Lead Game Programmer

33. Disciplines - Physics  Developing the physics in the game  Processor cycles are at a premium  Efficiency is key  FPS games typically demand large teams of physics programmers

34. Disciplines - AI  Develops the logic that the game uses  Has developed into a specialized area as of late  Pathfinding, strategy, and enemy tactics  According to Game Developer Magazine - 60% of time  Real time strategy and first person shooters

35. Disciplines - Graphics  Programmers who specialize in developing and modifying complex 3D graphics  2D graphics abilities are still useful though  Cell Phones  PDAs  Scarce in industry  Demand high salaries

36. Disciplines - Sound  Full musical scores - been around  3D positional sound - recent  First person shooters  Programmers try to include the newest technologies  Games with large soundtracks or advanced audio, demand teams of sound programmers

37. Disciplines - User Interface  Very important!  Must be intuitive, useful-feature, clean, and easy to use  Most user interfaces are 2D  Some interfaces are developed with the same 3D technology as the rest of the game  Advanced interfaces allow custom scripting

38. Disciplines - Input  Writes code that determines how the player will use the input devices  Controller  Joystick  Keyboard & Mouse  Wii controller  Motion sensing technology

39. Disciplines - Input  Programmers must recognize and adhere to controller standards  WASD  A (X) - accept // next  B (triangle) - back // cancel  If standards are not followed, gamers will be confused

40. Disciplines - Network  Writes the code that allows players to play the game on a LAN and or on the internet  Very important in Massively Multiplayer Online (MMO)  Latency control is especially important  Programmers cannot assume all consumers have broadband  Must be efficient  Might be dial-up gamers

41. Disciplines - Game Tools  Write code to handle tasks like scripting, converting art, batches, modifying the game and levels  Half-Life 2  Source SDK  Create levels (Hammer)  Facial animations

43. Disciplines - Porting  Porting is very important, especially for companies like EA  Games available on almost every platform  May involve the tools programmer to help convert content  Some code may have to be re-written to utilize different hardware

44. Disciplines - Lead  Keeps the programmers focused, and on track  Quite often a middle man between the client and programmers  Should have a general base knowledge of all aspects of the game  Sound  Graphics  Networking  Etc.
