Adding variables to link passages

Hi, I’m still getting used to this site, so I apologize if I do something wrong but basically, I want the player’s choices to have outcomes(?) in the game, and by that let’s say character relationships.

Let’s say I have characters named “Bob” and “Tom”
In my StoryInit passage:

<<set bobrel = 50>>
<<set tomrel = 50>>

Player has two choices:

Insult Bob. -10
Compliment Bob. +10

But I want the variable bobrel to increase/decrease when the player clicks a choice, does that make sense? Tell me if not.

Okay, now, this is where Tom comes in. Tom and Bob hate each other, so if player chooses to insult Bob, their relationship(Bob) will decrease by, say, 10%, and Tom’s will increase.
But if player chooses to compliment Bob their relationship(Bob) will increase by 10% Tom’s will decrease. (so like two variables in 1 link)

Any idea how to do that?

You can do it like this:

[[Insult Bob][$bobrel -= 10; $tomrel += 10]]

If you want to do something more complicated, you can also use the <<link>> syntax:

<<link [[Insult Bob]]>>
    /* any Sugarcube code here will be executed when the player clicks the link */
<</link>>

Thank you, it works!
