Timed Events that Vary According to Location

In the traditional sandbox-environment Interactive Ficton game, there are often puzzles to be solved through the discovery and manipulation of objects found in different locations in the game space. Keys to open locks. Code-breaking devices. Hidden treasures to placate or weapons to defeat enemies. In the Historical Williamsburg Living Narrative, the game play is somewhat different, primarily because the narrative is based on factual and well-documented events involving known historical figures. Entering locked rooms or discovering hidden passages, for example, isn’t as effective a way to advance the story, since the point of the game is to retell a story where the outcome is predetermined. To some degree, the player is more an observer rather than actual agent of change. That’s quite all right though, with interactivity being served by giving the player the ability to experience the story from different perspectives of time and place.

The narrative, then, is the main driver of game play, and in order to experience the game, the player needs to be in certain places at certain times. Unfortunately, it is the sandbox environment that challenges narrative integrity. For example, imagine that the player needs to overhear a conversation between two characters at a particular time and in a particular place. What happens if the player is in an entirely different location far removed when the conversation takes place? Here we see the need to provide latitude for the time and place for the occurence of events. Fortunately, creating a flexible framework to ensure exposure to relevant events is fairly straightforward.

The method is to determine a zone rather than particular location in which narrative drivers may occur, and then the actual event may occur after a particular time rather than exactly at that time. Finally, once the event has taken place, there needs to be a way for the game to track that so the event does not continue to trigger. The following code shows a way to handle this in Inform 7.

Here we see that the event is triggered if the time is after 5:08 PM (and not exactly at), as long as the variable placeevent has not been incremented from its initial value of 0. Once these criteria are met, the actual event occurs differently across six different locations. Finally, when the event takes place in one of two locations with the player there to witness it, the placeevent variable is changed.

This framework allows us to set up event conditions throughout the game (both in time and space), with enough latitude to ensure that the player experiences everything necessary to understand the game. The Historical Williamsburg Living Narrative is built on this foundation.
