I was introduced to the Colossal Cave Adventure game in 1980 when I got my first “real” job at an engineering company. The game was one of the installed pieces of software on the company’s Data General Eclipse mini computer. Soon after I started working there (spending countless after hours with coworkers exploring twisty passages), I purchased a TI 99/4A home computer, and I discovered Scott Adams’ series of text adventure games. Of course, I played them as quickly as I could get my hands on them. When I got my first IBM PC, I also got my first Infocom game (Deadline), which introduced me to a more sophisticated parser – to go with the greater computing power – and the idea that Interactive Fiction was more than simply text-based puzzles to be solved. The narrative was an integral part of the game experience, so the way in which things were described was just as important as the rooms that could be explored or the objects that could be examined. As the Infocom games came to tell more complex stories (anyone remember A Mind Forever Voyaging?), the narrative gulf between the new games and Colossal Cave became quite evident.
Working on the Historical Williamsburg Living Narrative, I am keenly aware of the need to provide narrative variation throughout the game, and it is especially important for continuity in the player’s actions. For example, when coming to a particular location for the first time, it makes sense to describe the experience:
“You approach the castle with a sense of awe at the scope. The walls tower over you as you slowly approach the massive iron gates. The construction effort for the outer walls alone must have taken years!”
While the above text might make sense upon first reading, seeing the same text over and over would greatly diminish the sense of reality and continuity in the game environment. Fortunately, Inform 7 provides built-in coding constructs to handle these situations.
The simplest situation to deal with is in visiting the same location multiple times. Inform 7 allows the application of conditionals that track the player’s location history:
[if unvisited]Write initial description here.[end if]
[if visited]Write subsequent description here.[end if]
While this takes care of a majority of situations, there are times when you may want to alter a location description based on whether or not the player has already visited a diffent location in the game. Let’s look at a situation based on a section of the actual game map.
For this illustration, we will focus on what is happening in the Capitol building desriptions. The Capitol is one of the main structures in Williamsburg, and it has appeal to the player character as part of the storyline. Accordingly, there should be some sort of acknowledgment of this in the description when the player encounters the Capitol. Using the [if visited] and [if unvisited] constructs apply only to the actual game locations, and this can be problematic in situations where there are more than one entry pont.
Notice that there are two entry points for the Capitol: the “Capitol Entrance” and the “Capitol Rear Entrance.” When the player first reaches either one of these locations, there should be a sense of excitement at seeing the Capitol. However, both locations need to “know” if the player has been to the other location, otherwise both the descriptions will portray that first-time sense of excitement, and that will be very narratively inconsistent.
Typically, the Inform 7 code might look like this:
The Capitol Entrance is a room.
“[if visited]This is the Capitol Entrance. You have been here before.[end if]
[if unvisited]You have never been to the Capitol before! Amazing![end if]
The problem with this approach is that the player could have already come to the Capitol from the Capitol Rear Entrance (and indeed even walked right through to the Capitol Entrance), which would make this description sound quite out-of-touch! Fortunately, Inform 7 gives you the ability to filter location descriptions based on what other locations have been visited or not visited. Something like this would be a start:
The Capitol Entrance is a room.
“[if visited]This is the Capitol Entrance. You have been here before.[end if]
[if the Capitol Entrance was not visited and the Capitol Rear Entrance was not visited]You have never been to the Capitol before! Amazing![end if]
[if unvisited]You have never come to the Capitol from this entrance.[end if]
There are three possible states represented above:
- The player has been to the Capitol before, and it was through this entrance. Therefore, there should be no initial reaction to entering the Capitol itself, or to encountering this particular location.
- The player has never been to the Capitol through this or the other entrance. All the “surprise” should be expressed here.
- The player has never been to this location, but the player has entered the Capitol through the other entrance. There should be the first-time reaction to this entrance but not to the Capitol itself.
You can begin to see the potential complexities in building a consistent narrative when dealing with a fairly complex game structure. There are many locations with multiple entry points, and the same process will need to be considered when encountering people or even objects for the first versus subsequent times. There are any number of ways to keep track of the narrative flow, and my primary tools are maps and spreadsheets. This, however, just scratches the surface of considerations for the location descriptions. Think about how descriptions may change depending on what other non-player characters have been there first, the time of day, or even the weather.
Clearly, we need to build a game timeline and make use of the appropriate variables as we move forward.
Note: As I write this entry, my family and I are in Colonial Williamsburg. (Yes, I am doing game material research while I’m here…) We will be enjoying Christmas dinner in Christiana Campbell’s Tavern (on the far east side of the map). So from my family to you and yours, may you have a very Merry Christmas and a Happy New Year!
The Interactive Fiction I grew up on (starting with the Scott Adams text adventures that I got in cassette form for my TI 99/4A computer) was all text based. No graphics at all; just two-word phrases that eventually turned into more sophisticated Infocom game sentences, but still words only. In fact, one of my favorite computer game ads was the Infocom print ad that said something to the effect of “We stick our graphics where the sun don’t shine,” and then there was a picture of the human brain. Pretty clever, and you can see it here.
One of the characteristics that makes Inform 7 so appealing as an IF development environment is that it allows a person to rapidly put together an IF game in the form of those old Infocom games: a pretty robost parser that allowed for sentence input. However, Inform 7 has made a number of improvements to the output it produces, compared to the earlier Infocom games. One of those improvements is the ability to integrate graphic images into the Inform code for display when someone plays the game.
I’ve decided to take advantage of this feature during development of the Historical Williamsburg Living Narrative. I’ll be using the photographs I have taken of Williamsburg, and I’ll have the photographs changed into a more comic-like illustration. Below is a sample of the Capitol Building already having gone through the image processing.
As you can see, the photograph has been altered to appear as more of an illustration. I’ll do this for all of the photographs to be used in the game. Please share your thoughts: do you like this approach to Interactive Fiction? Or does IF need to be more “old school”?
Getting into Interactive Fiction isn’t the easiest thing to do, as far as playing a “new” computer game genre goes. In the early 1980s when IF was popular–and the distractions of graphic computer games was non-existent–people spent significant time in the games, reading the stories and situations, thinking about how to respond, and considering the possible (or probable) action choices to take. In the days of playing Colossal Cave and Scott Adams text adventure games, the simplicity of the parser forced people to think in terms of two-word commands. That had the effect of narrowing action choices to some degree, which was probably a good thing as the genre gained its following. As Infocom released its games with more sophisticated language parsing capabilities, the potential for action and conversation was greatly multiplied. But most Infocom players likely had an introduction to the genre that helped to educate them in the conventions of IF communications.
Today, learning IF games can be difficult for several reasons. Finding a local IF community can be difficult (okay, impossible in most cases), which means that players need to rely on online resources–if they can successfully find those. The computer gaming paradigm has shifted greatly over the past few decades, and as a result, people’s expectations for game experiences is quite different.
Fortunately, there are freely available resources that help ease a new IF gamer into the genre. Instructions, primers, and how-to guides can be found by searching the Internet. And there are many good games suitable for novice IF gamers. This article on the gamer site 1up has listed what could be considered the top 5 games for Interactive Fiction beginners to try first. Try your hand!
While the Historical Williamsburg Living Narrative isn’t being developed strictly with novices in mind, if it will be used in the teaching and learning environment it will need to be something that students can easily pick up on. To find out more about the Kickstarter project, please click here.
One of the great joys of playing Interactive Fiction games is in the discovery and exploration of the physical space or actual play environment of the game. Years ago when I played the Colossal Cave Adventure for the first time (on the Data General Eclipse computer at the office after hours), I delighted in drawing maps for all the locations and paths that were available. When I got to the maze area, where room exits looped back into the same room, the value of the mapping process became very clear. Those skills were well utilized as I grew into the Scott Adams adventure games, and later the collection of games from Infocom. Sketching out the location boxes with their associated path connections became second nature as a necessary Interactive Fiction player skill. (I am often surprised when I teach Interactive Fiction to college game design students, how few of them already know or readily develop the map-making skill set.)
Developing maps for IF is a slightly different process, though, that requires more than drawing boxes with interconnecting lines. There is the idea of location scale and relative size in IF games, and the developer needs to make some important decisions before committing to computer code. Locations are not all uniform in size (when we imagine our settings), and logical layout is not the same as physical layout. When dealing with fictional settings, there is some latitude for interpretation (though the good designers have a very clear picture of their environment before starting to code). However, there is no room for creative interpretation when attempting to recreate historical settings with absolute fidelity to the historical reality.
That’s our situation with the Historical Williamsburg Living Narrative. A large part of the questions could be framed around geographic granularity: as we build the maps, what is the smallest unit of measurement we should be using? (A square yard seems reasonable, actually.) There will be the typical Interactive Fiction flex in the maps; for example, walking down one side of a street may result in more “stops” along the way than walking up the other side. That would have much to do with the buildings or other pathways located on each side. But the point is, we need to make consideration of the space or area that needs to be “reserved” for game locations in which action may (or may not) take place.
I’m making my sketches now, and that will be one of the first pieces of the game that will be ready for review (we may even put that up on Playfic for people to try out). Do you have any suggestions regarding map making? Is that something you enjoy doing? If you’d like to contribute in some way on this (or any other) piece of the project, please drop me a line.
