Artificial Intelligence Tutorials  

      Quake is old.
      But for a long while now, you've had an idea. You've wanted to modify the monsters somehow. Or you wanted to add bots to a deathmatch mod you play on the net.
      You might have been afraid of learning QuakeC because you've never programmed before. Maybe you've tried, but you couldn't translate your idea into code.
      That will now change. Welcome to my series of artifical intelligence tutorials. Whether you don't know much QuakeC, or whether you have started your own bot, you'll learn how to program AI.
      This ongoing series will be delivered in four phases:

      1. Learning the Basics
      2. Making a Monster Bot
      3. Building a Deathmatch Bot
      4. Creating a Bot Game

      I have two goals with this series. One, I want total conversion programmers to learn how to build more interesting creatures. Two, I want others to add bots to deathmatch games that are normally played over the net.
      These lessons will also be shaped by you. If you want to see a certain tutorial, or if you have source code for a cool patch that could use AI, let me know and I'll do it.
      It is strongly recommended that you read the QuakeC manual, look over the QuakeC source code, and do the tutorials at Inside3D before you start on the AI lessons.
      One thing you should know: we're not here to make the smartest bots. That would be boring. We're here to create cool enemies. We're here to have fun.
      Okay, now it's time for some monster brain surgery.
