• Example: * East Side West Side - A bare minimum example of setting up Regional Travel.
• Example: ** The Detective - Driving around the city in a car.

The Regional Travel extension adds a new action, traveling regionally to, that allows the player to travel between different regions with the command TRAVEL TO. This kind of technique is sometimes used in games where the player can travel between distant locations, for example between cities or between separate locations inside a city. The extension can also be used when the player needs a vehicle for traveling to certain areas (see example B for a demonstration).

The minimal setup is to group rooms into regions (see chapter 3.4 in Inform 7 (5Z71) documentation) and define what is the "travel entry point" of each region. The travel entry point is the room where the player will end up when traveling to that region. Note that the travel entry point doesn't actually have to be inside the region. Example A demonstrates a basic setup.

By default the player can't travel to any region that is unvisited. If we want the player to be able at any point of the game to travel somewhere they haven't visited yet it's recommended to include another extension, Epistemology by Eric Eve. When we're using Epistemology we can make a room 'familiar' which allows traveling there. See Epistemology's documentation for more information or example B for another method for granting travel access to an unvisited location.

There are some default messages that are displayed to the player in different situations. They are: The unknown travel destination message, the destination not in a region message, the already there message and the already in the region message. These are "some text that varies" and they can be changed during the game or in a "when play begins" rule:

    When play begins:
        change the unknown travel destination message to "That sounds like an implausible place to go to.";
        change the already in the region message to "[The noun] is just around the corner."
