Twine 2 status?

[Martin Ellison]

Hello everyone, how is Twine 2 going?

Also, is there more documentation. I cannot work out how to use arrays. How do I add a new member to an array? Can I join arrays to make a string? (I was trying to make an inventory list).

Hi, Martin! Good to have you here.

Turns out Twine arrays are handled like standard Javascript arrays--which are themselves a little strange IMO. Here's how to add something to a list (within a Twine passage):

    <<set $currentLoops = [] >>

    <<set $march = "march.mp3">>

     

    Add a parade...

    <<set $currentLoops.push($march)>>

    Now remove it...

   <<set $currentLoops.splice($currentLoops.indexOf($march),1)>>

If there's a simpler way to remove a given item from a list in Twine, I haven't seen it.

I'll look into adding this to the Twine wiki under "Scripts."

I hope this helps. Holler! if it doesn't.

You should be able to join arrays for printing using Javascript.

<<print $myarray.join(", ")>>

Change the bit in the double quotes to get a different list seperator.

Ahhh, I left out that bit! Thank you, Stormrose!

WIll add to the wiki...

I was asking about Twine 2 specifically, and your remarks appear to be about Twine 1.x.

Regards,
Martin

Correct. My bad.

@Stormrose: no need to apologise; I'm sure someone will find your comments useful. But I'd like to know if Twine 2 is still actively under development.l

It sure is! You can follow updates on the Twine 2.0 story format Harlowe at bitbucket: https://bitbucket.org/_L_/harlowe/commits

Hope this helps.

You can make the syntax from removing items from an array simpler by adding this code to a passage tagged [script]:

// Removes an element from an array.
// String value: the value to search and remove.
// return: an array with the removed element; false otherwise.
Array.prototype.remove = function(value) {
var idx = this.indexOf(value);
if (idx != -1) {
    return this.splice(idx, 1); // The second parameter is the number of elements to remove.
}
return false;
}

Then you can remove an item like this:  <<set $currentLoops.remove($march)>>

I stole that code from http://www.simonewebdesign.it/how-to-remove-element-from-array/
