Simple Myst-Like Application

[Jim Ault]

As far as points not being duplicated, here are a couple ways you might do
it...  here is one of the simpler ways

First make all the points on a single card (scene) different, eg 9,11,13,5.
That is,  each card can have one object worth 5 points.
Second, use a global where each line of the global will correspond to the
number of a card
Third, put the points scored as a new item on the line for that card

global gUserScore

on addNewScore pointsToAdd
  put the number of this card into cdNum
  if pointsToAdd is not among the items of line cdNum of gUserScore then
    put comma & pointsToAdd after line cdNum of gUserScore
    get gUserScore
    replace cr with comma in it
    put sum(it) into fld totalScore --shared text
    --assumes shared text field "totalScore" is visible on all cards
  end if
end addNewScore

gUserScore
,5,8,6,12  < line 1
,5,12,2  < line 2
,9,4,5,2  < line 3

put sum(,5,8,6,12,,5,12,2,,9,4,5,2) --  70

Since gUserScore is a global, you will always have a point record, even if
they revisit a card and try to pick up more points.  Only new points will
work.
