3D Game Programming All in One- P12

3D Game Programming All in One- P12: During the past several years while working on the Tubettiland “Online Campaign” softwareand more recently while working on the Tubettiworld game, I figure I’ve receivedmore than a hundred queries from people of all ages about how to get started makinggames. There were queries from 40-year-olds and 13-year-olds and every age in between.Most e-mails were from guys I would estimate to be in their late teens or early 20s.

All of the scripts loaded are part of the common code base. We will look at selected key modules from these calls in the rest of this section. Selected Common Server Modules Next, we will take a close look at some of the common code server modules. The modules selected are the ones that will best help illuminate how Torque operates. The Server Module InitBaseServer loads the common server module, server.cs. When we examine this mod- ...
