Modifying state of array element in Harlowe 2.0.11

randumbdaze

So I've declared

(set: $foo to (a: false, false, false))

For some reason, I can

(set: $foo's 1st to true)

but I can't

(set: $foo[0] to true)

The latter keeps saying unexpected identifier. I'm trying to do something kind of complicated but in order to isolate the problem I wrote this simple code:

(set: $foo's 1st to true)
(if: $foo's 1st is true)[bar]

That works. This doesn't??

(set: $foo[0] to true)
(if: $foo[0] is true)[bar]

I want to use a variable in the $foo array so I don't have to repeat code. Am I doing something wrong...?

I mean Harlowe 1.2, Twine 2.0.11, my bad.

Harlowe does not support Javascript's syntax for accessing an array element, but if you reed the Array documentation you will see that you can use the $variable's (index) syntax instead.

(set: $array to (array: "one", "two", "three"))
(set: $index to 1)

1st element (number): (print: $array's (1))

(set: $array's ($index) to "not one")
1st element (variable): (print: $array's ($index))

note: Harlowe's arrays are one based, using zero will return the last element of the array.

Ahhhh thank you! I don't think the parentheses are needed around the index but I got it to work. Thanks!

I use the parentheses because the documentation states you should, because ($index) is an expression. If the Harlowe markup parser currently supports not using the parentheses then that's fine unless that is a bug, in which case not using parentheses could stop working in a later version.

Experience has taught me that just because something works does not mean it's how you should do it. lol

i tried using the parentheses but it returned nothing so I took them out

That's strand because I test my example code before posting it.
