Hello everyone,

I'm creating a dressup game for kids, which will have a score system. There
are 3 items of clothing worth 10, 15 and 20 points. On one page they can
select the garments. I've created a global variable called gScore and have set
it to 0 in startmovie.

On the sprite of each garment of clothing I've used the following code

gscore = gscore + 20

Thing is, each time you click, it adds 20 to the total. so if you click
twice, the total will be 40. I only want it to be add to the total once and not
each time a user clicks.

If the user click on another garment of clothing; for example worth 15 points,
that will be add to 40. I also don't want this to happen as the user can only
select one garment of clothing. So basically the user can score a maximum of
20 points, because they can only select 1 as this point.

If I select the garment worth 15 points, and change my mind and select the
garment worth 20 points, how can I recognise this and deduct 15 point from the
total and add 20?

Its sounds confusing... Thanks everyone

Instead of (or in addition to) your gScore global, I would make another
global for each clothing type. I have no idea how your game is
structured, but let's say you have Shirts, Pants, and Shoes. Each time
you click on a shirt, it will put in that shirt's value and remove the
previously saved shirt value while leaving the rest intact.


global gScore
on startMovie
gScore=[:]
gScore[#shirts]=0
gScore[#pants]=0
gScore[#shoes]=0
end

That will instantiate your list when the movie starts. Then you would
put this on each clickable clothing item:

global gScore
property pGarmentType
property pValue

on mouseUp me
gScore[symbol(pGarmentType)]=pValue
end

on getPropertyDescriptionList me
p=[:]
p[#pGarmentType]=[#format:#string,#comment:"Which garment
type?",#default:"shirts",#range:["shirts","pants","shoes"]]
p[#pValue]=[#format:#integer,#comment:"How much is this one
worth?",#default:0]
return p
end

(watch out for inadvertent line breaks - that should be exactly 14 lines
of code) That will let you define which garment type the item is, and
how much it is worth. Feel free to set the different garment types to
be appropriate for your use...

Anyway, on your score counter, you would simply add the values together
like this:

global gScore
on enterFrame me
theScore=gScore[#shirts]+gScore[#pants]+gScore[#shoes]
sprite(me.spriteNum).member.text=string(theScore)
end

Thanks Mike,

I'm having trouble understanding the code that goes into the clickable item of
clothing. I am also getting an error message
gScore[symbol(pGarmentType)]=pValue - Index out of range

There are three outfits to chose from. I've named them : Outfit1, Outfit2,
Outfit3
Outfit1 = 10 points
Outfit2 = 15 points
Outfit3 = 20 points

how does the following code work?

p[#pGarmentType]=[#format:#string,#comment:"Which garment
type?",#default:"shirts",#range:["shirts","pants","shoes"]]
p[#pValue]=[#format:#integer,#comment:"How much is this one worth?",#default:0]

I'm not familiar with properties

Thanks again so much for your help, hopefully I'll learn something new!

Many Thanks

That stuff is part of the "getPropertyDescriptionList" handler.
Basically, when you put the script onto a sprite, it will present you
with a few options. And the options you choose in that menu will define
how the script works. In this case, there are 2 questions it will ask.
One is garment type and the other is value.

You will get the value out of range if you are trying to set the score
of a garment type that does not exist.

In startMovie, we set three different garment types, Shirts, Pants, and
Shoes. Each clickable clothing item will be one of those three types.
Which one it is will be defined by your selection in the GPDL.

If it is easier to understand without using properties, the point of the
situation is that we have 3 globals defining the score. Not just the
one gScore. I separated them and put them into a single property list.
You could use 3 globals like gShirtScore, gPantsScore, gShoesScore.
Then each time you click a Show item, it sets the value of gShoeScore.
And the text sprite that shows the actual score simply adds the three
together.
