We’ll be giving the bad guys pursue, attack, flyby and flee behaviours. How do we do this without all of the bad guys behaving identically? If we’re not careful they will flock together and fall into synchronized movements. Worse, they could be predictable (not much fun for a game!). Artificial intelligence (AI) is an interesting subject. Is the solution smoke and mirrors or do we need to program something “intelligent”?
Welcome back! In this issue you will learn how to add a sky to your game, add some lighting and some fog. You will create controls for your player and be able to fly around your 3D world, barrel roll, loop-the-loop and more! We’ll also dip into how the camera works and how to control it while also explaining how positioning and transformations work. With a further snippet on performance tuning there’s a lot to cover, so away we go…!
All of the Issues in Volume 1 rely on something called Panda3D. Panda3D is a 3D game engine provided completely free by the Carnegie Mellon Entertainment Technology Center. A game engine is a Software Development Kit (SDK) that takes the pain out of the common tasks involved in game development. For example, Panda3D provides libraries for graphics, physics, lighting, audio, keyboard/mouse/other input and so on. You really would not want to find yourself having to write all of these routines yourself (you’d never finish a single game on your own!). There are other game engines out there but we really like Panda3D due it’s ability to run on Windows, Linux and Mac and its support for Python:
