With the ability in 3.1 to call things from within single-quoted strings, this should be pretty easy. I would create an object called scoreKeeper that would do the actual arithmetic. I would then write hints like this:
Code:
++ Goal 'How can we get past the cyclops?'
[
'<<scoreKeeper.minusOne(cyclops)>>Oh, dear --- are you sure you want to try? ',
]
;
This assumes (a) that the cyclops is an actual game object, and (b) that scoreKeeper is set up something like this:
Code:
cyclopsReduced = nil
minusOne(obj) {
if ((obj == cyclops) && (!cyclopsReduced)) {
cyclopsReduced = true;
scoreValue = scoreValue - 1;
}
}
This insures that the score will be reduced only the first time that that hint is read. Note that this suggestion doesn't actually tell you how to reduce the score -- I haven't researched that. I'm just suggesting how you would set it up. Possibly you would want to use an Achievement object with a negative value.
