How to make the player select x number of options out of a checklist?

Question

So my game is about life in college and I want to let the player select their classes from a set list. I want them to have to take a certain amout of class (right now I'm thinking 7) but I'm not sure how to make them have 7 (or more) options selected in a checkbox list. The best example I can think of is Fallout's S.P.E.C.I.A.L. system at the beginning of the game.(except with checkbox's instead of multiple points to each stat)

Is there a way to do this?

Answer 1

If you're using checkboxes, then you'll have to count each value.

Assuming that you're simply using true/false values something like the following:

<label><<checkbox "$classOne" false true>> Class One</label>
<label><<checkbox "$classTwo" false true>> Class Two</label>

Etc.

Then you could do something like the following to count the number of classes which were picked:

<<set _classCount to [
	$classOne,
	$classTwo,
	$classThree,
	$classFour,
	$classFive,
	$classSix,
	$classSeven,
	$classEight,
	$classNine,
	$classTen
].count(true)>>\
<<if _classCount lt 7>>
/* Less-than 7 classes were picked. */
<</if>>

 

SEE: <<checkbox>> and <Array>.count().
