Right, here goes, bear with me...

I have a card, with two buttons on it ButtonL and ButtonR, and a label at the top called MatchLabel which will contain a single digit no. I want that label to match the number on either ButtonL or ButtonR

I have a custom property set up on the card called cNumberPairs which contains:-

1 0
2 0
3 0
4 0
5 0
6 0
7 0
8 0
9 0
0 1
2 1
3 1
4 1
5 1
6 1
7 1
8 1
9 1

Etc. and so on, of all the possible number combinations excluding matching pairs.

What I want to happen is, the single digit number will be displayed at the top (I will have a start button) and then when the matching ButtonL or ButtonR are clicked on the label at the top changes to another random single digit number as does ButtonL and ButtonR

I have done some reading around arrays and have managed to get the button labels to change to the first line of the array when the array is sitting on the card in a field below but I don’t want the data to be seen so I have moved it to a custom property on the card.

I am unable to get the data onto the button labels now and have got all confused with arrays and custom properties are they things you use either one or the other of or do you use them together.

I hope that all made sense

I tried reading this several times, and still do not quite get it.

The good news is that I see enough of what you are trying to do to know that the answer will be very simple. And I think a custom property will do nicely.

So you press a start button, and then what? Does a random digit load into the label field? If so, do random digits then modify the button labels? Does one or the other of those button labels load with the field digit? Is the idea to see that one or the other buttons shows the same digit, and one should then push that button?

Write back. This will be fun.

Sorry I did try and make it less confuisng

What should initially be seen should be a single digit number between 0 and 9 in the label field. Also at the same time you would see two buttons a left and a right one, one of which contains a matching number (they cannot both match). When either of the left or right buttons are clicked the field label button should change to another random single digit number between 0 and 9 with another set of numbers on the left and right button (only one of which matches). I set the cNumberMatch custom property to contain :-

1 0
2 0
3 0
4 0
5 0
6 0
7 0
8 0
9 0

Which is every single digit combination without having duplicate numbers, I had hoped to get the pairs to appear in a random order.

I did get the feeling this should be simple but I am only just learning the language at the moment.

I work with learning disabled pupils, this is a technique called matching to sample, they are presented with a number and they have to matching from two possible numbers. Is there also a way of recording how many they get right?

Many thanks

Does that make more sense?

Yes. I get it now. Seems like a worthy project.

So in your "start" button, does this make sense"? This assumes you have four buttons. One named "start", one named "B1", one named "B2", and one named "testNumber". I did not use a label field. I wonder why?

Your payment for this is to read each line and understand it. There are a million ways to do the cutesy number gathering. I used a brute force method, but it is easier to read. Further payment would be to make this your own with new functionality or reworking what is already here, like using a custom property in some way. This does not. Write back...

Hi...

To get your 'pairs' to appear in a random order... try something like
Also, have a look at 'random' in the dictionary to help you decide which number of a pair you will display in your 'label' field...

I'll leave the rest to Craig

be well

Dixie

Payment will be recieved in full, you just may have to give me a bit of time

Thanks

Hi Craig

Am I correct in presuming possibles, currentDigit , currentButton and otherButton are variables?

If so is there any reason why they are not called tPossibles, tCurrentDigit, tCurrentButton and tOtherButton? So far I have only come across variable with t in front of them. Is this significant?

Oh are variables and temporary variables different? Eek

This is what I think is happening in the code. Am I correct?

put "0,1,2,3,4,5,6,7,8,9" into possibles --This randomly assigns 0-9 to possibles

put any item of possibles into currentDigit -- This randomly assigns any digit in possibles to currentDigit

delete item currentDigit + 1 of possibles -- why + 1? --hmm I know what it is doing but am not sure why it is doing it. It stops the same digit appearing on B1 and B2. When I make it +2 it is possible to have the same number on B1 and B2 and when I take +1 out it is also possible to have the same number on B1 and B2. Am confused if currentDigit is the one that is to be matched then why is it currentDigit +1 rather than currentDigit that gets deleted from possibles? I have even had a look in the variable watcher. I guess there is a really simple answer to the question but it is eluding me at the moment

set the label of btn "testNumber" to currentDigit -- This sets the button “testNumber” label to currentDigit

put any item of "1,2" into currentButton
if currentButton = 1 then put 2 into otherButton else put 1 into otherButton
-- These two lines randomly assign B1 or B2 to be the correct answer

set the label of btn ("B" & currentButton ) to currentDigit
set the label of btn ("B" & otherButton ) to any item of possibles
-- These two lines sets the labels of B1 and B2 but how come they are referred to as B rather than B1 or B2? Does referring to them as B mean you refer to both or either? What does the & do it’s not in the dictionary

I did not use a label field. I wonder why? I am afraid I have no idea?


Hi Craig and Dixie

I have taken bits of both of your code and have come up with this:-
The first part sort of works where I get data from cNumberPairs to show in ButtonL and ButtonR, I say sort of works because it doesn’t work if I click either of ButtonL or ButtonR but it does work if I click anywhere else. I thought that if there was no code on the button then the message would be passed up to the card?

The next bit to not work is the bit where I try to get testNumber to randomly match ButtonL or ButtonR

Have learned quite a bit I think but further help would be appreciated

Hi

It seems to be something to do with
in the variable watcher it puts 1,2

but
in the variable watcher this puts either 1 or 2

the only difference between the two lines of code, that I can see, is one code is on the card and the other is on a button?

any ideas?

Can you post your stack... as I am still confused about what you are trying to do..

Only if you tell me how to

When you 'click' .. 'Post Reply' to answer this posting you will see a tab under the 'Save Draft', 'Preview' and "Submit' buttons that is titled 'Upload Attachment'.
Clicking on 'the 'Upload Attachment' tab will allow you to browse to your stack to select it... (zip your stack to post it) once selected you can then click on the 'Add the file' button to attach it to your post...

erm I can't find the file to zip it up, I have the file path 'C:\Program Files\RunRev\LivecCode 5.0.2\Matching to Sample.Livecode' but when I go looking for it it is not there. I have the computer set to show hidden files?

I even changed the file name to be able to search for it, it does not show up?

What am I doing wrong?

Hi... I don't know what you are doing wrong
You could email it to john@ihouse.on-rev.com

be well

Dixie

Good grief...

... have managed to zip it up now had to send it to document before I had to send it to compressed file...

...have never had so much trouble compressing a file!

right where was I

I do hope that worked. Fingers crossed

I have changed your scripts a little... look at the scripts of buttons left and right and the card script...

I hope it helps

be well
