INTERVIEW TO THE TEAM BEHIND "TOWER DEFENSE"

Zygote has interviewd the guys behind the game "Tower Defense".

From the interview: "... There are four of us currently under the Focused Games umbrella. Justin O'Dell (Anxiety), has been taking care of a lot of the core gameplay functionality such as how the map works and how state, player and enemy management works. Matthew Randall (EviLDeD) wrote the entire audio core for the game, and also did quite a bit of work with Towers and Enemies to get them to track, shoot, move et cetera. Mart Slot is the one responsible for all the fancy particle effects in the game, which will be more prominent in the future. I, John Sedlak (Krisc), have been responsible for the user interface and a lot of the front end work like how the user interacts with the map, how they change levels, and build towers ...".

Fortunately, XNA provides most of the functionality for matrices that you will ever need without having to worry about the complicated math behind that functionality. However, it is necessary to have an understanding of what this functionality is actually doing in order to apply it correctly in your code ...".

QUATERNION CAMERA IN XNA

Scot Boyd, author of the upcoming book "Expert One on One: XNA Game Programming for Xbox 360 and Windows", has provided the source code of the "QuaternionCamera" class which will help you avoid that nasty Gimbal Lock problem that you may face when working with yaw, pitch and roll at a time.

From the post: "... XNA unfortunately does not provide a QuaternionCamera class in it's Framework. Nowhere on the Internet could I find a camera class that provides six degrees of freedom without requiring additional coding from the reader ... In the process of attacking this problem in my book, I've made a few camera classes. I'm posting the simplest class here - good for beginners. The final camera class in the book will be more complicated. This class should provide a good jumping-off point for anybody interested, or a simple helper class for those who just want a camera without hassles. In the camera, GetViewMatrix and CreateYawPitchRoll are where the money is ...".
