Update: This script is now built into Twine 1.4! It is no longer necessary to install it.

This is a very short script that allows you to use a function called "either" in Twine's <<set>>, <<print>> and <<if>> macros. Give it several string or number values, separated by commas, and it will pick one of them randomly to use in the macro.

Obsolete script removed: use Twine 1.4

This functions largely identically to the Game Maker choose() function. You can use it like this:

<<print either("a dusty glade", "a sinister vale", "a murky gully", "a desolate gulch") >> - Prints one of the strings, chosen randomly.

<<set $value = either(0,1,2,3,4)>> - Sets $value to one of the numbers.

<<if either(true, false)>> - This is true 50% of the time. Equivalent to <<if Math.random() lt 0.5>>

In the first case, you can see it's functionally similar to the <<rnd>> macro - but, as demonstrated, it can also be used inside <<set>> as well as <<print>>.

If you patch the <<display>> macro, you can also use it to display a random passage, serving as a more primitive kind of <<randomp>>:

<<display either("Cellar", "Garden", "Observatory")>>
