Jay Simon 3/18/2002 STS 145 Case Study Zork: a Study of Early
Jay Simon 3/18/2002 STS 145 Case Study Zork: A Study of Early Interactive Fiction I: Introduction If you are a fan of interactive fiction, or have any interest in text-based games from the early 1980’s, then you are no doubt familiar with a fascinating series known as Zork. For the other 97 percent of the population, the original Zork games are text-based adventures in which the player is given a setting, and types in a command in standard English. The command is processed, and sometimes changes the state of the game. This results in a new situation that is then communicated to the user, restarting the cycle. This type of adventure game is classified as belonging to a genre called “interactive fiction”. Zork is exceptional in that the early Zork games are by far the most popular early interactive fiction titles ever released. It is interesting to examine why these games sold so well, while most other interactive fiction games could not sell for free in the 1980’s. As we will see, this is a result of many different technological and stylistic aspects of Zork that separate it from the rest of the genre. Zork is a unique artifact in gaming history. II: MIT and Infocom – The Prehistory of Zork Zork was not a modern project developed under a strict timeline by a designated team of programmers, but credit is given to two MIT phenoms named Marc Blank and Dave Lebling. Its history can be traced all the way back to the invention of a medium-sized machine called the PDP-10, in the 1960’s. -

Z-Machine Interpreters in the 1980S, Infocom Published About Three
By Hugo Labrande Issue #5 : Z-Machine interpreters In the 1980s, Infocom published about three dozen of text adventures on most platforms of the era, from the TRS-80 to the Atari ST. Their method to spend minimal time on portability was to create a virtual machine, the Z-Machine, and compile their games into bytecode that could be read by the Z-Machine. All was needed was some software that could read this bytecode and execute it on a target machine: an interpreter. To ensure that all interpreters behaved coherently, Infocom actually wrote specifications for the Z-Machine (version 3, 4, and 5 for text-only, and 6 for graphical adventures), which specified how the interpreter should behave; this was to make sure that the people tasked with writing a new interpreter would follow the same rules as the other ones. This specification was then reverse-engineered by amateurs as early as the end of the 1980s (Barry Boone on the TI-99/4A, the InfoTaskForce in Australia, etc.). In the 1990s, people added some features and fixed a few inconsistencies, and created version 8, which was basically the same as version 5 but allowed larger file sizes. This gave the Z-Machine standards, which are available online: http://inform-fiction.org/zmachine/standards/z1point1/index.html This means that if you’d like to implement a Z-Machine interpreter, all you need to do is follow this specification. Over the years, literally hundreds of Z-Machine interpreters have been written, for sometimes very exotic platforms. They sometimes have their own quirks, can fall out of fashion, or get forgotten; I cannot begin to retrace all the Z-Machine interpreters that have been written. -

You sit on your bed, thinking of better times and far-off places. A knock on your door stirs you, and Hevlin, a shipmate you haven't seen for years staggers in. "I'm in trouble," he says. "I had a few too many at The Shanty. I was looking for Red, but he wasn't around, and I started talking about.... Here," he says, handing you a slim volume that you recognize as a shipwreck book written years ago by the Historical Society. You smile. Every diver on the island has looked for those wrecks, without even an old boot to show for it. You open the door, hoping the drunken fool will leave. "I know what you're thinking'," Hevlin scowls, "but look!" He points to the familiar map, and you see new locations marked for two of the wrecks. "Keep it for me," he says. "Just for tonight. It'll be safe here with you. Don't let--." He stops and broods for a moment. "I've got to go find Red!" And with that, Hevlin leaves. You put the book in your dresser and think about following Hevlin. Then you hear a scuffle outside. You look through your window and see two men struggling. -
GRUE: an Architecture for Agents in Games and Other Real-Time Environments
GRUE: An Architecture for Agents in Games and Other Real-Time Environments Elizabeth Gordon, BS, MSc. Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy March 2005 Abstract This thesis presents an architecture, which we call GRUE, for intelligent agents in real-time dynamic worlds. Such environments require agents to be able to flexibly adjust their behaviour to take into account changes in the environment or other agents’ actions. Our architecture is based on work done in robotics (Nilsson, 1994; Benson and Nilsson, 1995; Benson, 1996), which also deals with complex, dynamic environments. Our work focuses on goal arbitration, the method used by the agent to choose an appropriate goal for the current situation, and to re-evaluate when the situation changes. In the process, we have also developed a method for representing items in the environment, which we call resources, in terms of their properties. This allows the agent to specify a needed object in terms of required properties and use available objects with appropriate properties interchangeably. We show that the GRUE architecture can be used successfully in both a typical AI test bed and a commercial game environment. In addition, we have undertaken to experimentally test the effects of the features included in our architecture by comparing agents using the standard GRUE architecture to agents with one or more features removed and find that these features do improve the performance of the agent where expected. ii Acknowledgments First of all I would like to thank Sony Computer Entertainment Europe, who provided the majority of my funding, and express my gratitude to Ian Wright and Dave Ranyard who made it possible. -
