Help with making random passage destinations less random (Harlowe 1.2.2, Twine 2.0.11)

darksonic

The basic set-up: I have a maze-like area, with a "hub" room that randomly leads to one of 10-ish other rooms. Using (either: ) means each of those rooms has a roughly equal likelihood of being found. The player then returns to the hub and gets another random room the next time they explore.

What I would like to do is set it up so that rooms that have already been seen are less likely to come up on subsequent explorations, but still have a small chance to do so. I have a couple VERY rough ideas as to how to set this up, but hoped that maybe someone out there had a solid method for doing such a thing.

Hopefully that explanation is clear. Thanks!

Um... someone correct me if I'm wrong, but you could store the values (room names of numbers) in an array, use (either:) on the array:

(set: $rooms to (a: rm1, rm2, rm3))
(set: $selected to (either: ...$rooms))

That would just select one, and they all would have the same chance always, until you add something that takes the room out of the array, like this:

(set: $rooms to $rooms - $selected)

With this setup, though, you can only go to the room once, so maybe you could add a chance that the room will be removed (all code):

(set: $rooms to (a: rm1, rm2, rm3))
(set: $selected to (either: ...$rooms))
(set: $remove to (either: 0, 1))
(if: $remove is 1)[(set: $rooms to $rooms - $selected)]

By changing the last either statement to have more values (i.e. pick 1, 2 or 3, but it only counts if it's 1) you can change the chance. Anyway I pretty much just started with Harlowe and Twine so someone please correct me if I'm wrong.
