"If", "Variables" and madness

[AsgharD]

Hi to all. I was wondering, for my next adventure game, to use a mental sanity sistem structured with the "if" and "variables" aspects of Twine.

Something like this:

START WITH MENTAL STABILITY AT 0 > VISITING CERTAIN TEXTS ADD OR REMOVE STABILITY > WHEN STABILITY IS UNDER CERTAIN NUMBERS, SOME "IF" ARE TRIGGERED

I was thinking something like this, how do you think i can obtain something similar in twine?

Thank you.

Hi Asghar! Thank you for your interest in Twine! 

Here's how I would go about it.

: Start

<<set $mentalStability = 0>>

There is a book of arcane studies.

Read the [[book][$mentalStability -= 10]]

Touch the [[book][$mentalStability -= 5]]

Absolutely don't touch the [[book]]

: book

<<if $mentalStability < -5>>

You are stark raving mad.

<<else if $mentalStability < 0>>

You are going mad.

<<else>>

You are fine.

<<endif>>

OR

You can link to different passages, too, change the variable within the passage, and join up after. I prefer changing the variable in the link because the connection to the action is more clear.

Note that <<else if>> is appropriate for the Sugarcane/Jonah story formats, but <<elseif>> is necessary for Sugarcube.

More information about if/else is available on the Twine wiki here: http://twinery.org/wiki/if

I hope this helps. Happy Twining!
