Re: Card's Game

Hello Alain!
  I understand the problem with turtlesown, and I fixed it.
  to the second question- to identify whether the two cards are the same' I 
want to do it more simple, but I didnt succeeded to get the names of the 
turned turtle, Is there an instruction to get the names of the tutrles  like  
get pos , get rule and so on.
  there will be a procedure "right" that will get the name of the two turtles 
and thenhide them' and another button "wrong" that will turn the cards to 
their opposite side.
                                  Thanks, Zehava Wizman

  Hello,  

  Turtlesown is a command that you use "only once" in a given project. Once 
done, you never have to do it again, the variable is created. After a 
TURTLESOWN "TRY command, you can use SETTRY and TRY instructions as much as 
you want. Your STARTUP procedure tries to "recreate" the variable and it 
already exists. That's why you have an error message.
  

  Solution: remove the TURLTESOWN command in your startup procedure. You don't need it at this point.
  

  About finding pairs: You can take a look at the project PAIRS in the project 
library (MW JR area at www.microworlds.com). It is a MW JR project. You can 
see it in your browser if you have the MicroWorlds EX plugin for Macintosh 
(Windows to come later)
  

  One way to check if two flipped cards have the same shape (with lots of 
"unknown" that I leave to you)
  

  ; run this once to create the project variable
  createprojectvar "flippedcards
  

  

  ; the Onclick instruction of every card: FLIPANDCHECK
  

  to flipandcheck
  flipcard
  ; if the card you just flipped is the second flipped card...
  if (count flippedcards) = 2 [compare]
  end
  

  to flipcard
  ; put the name of the current turtle in the list of flipped cards
  setflippedcards fput who flippedcards
  setsh ?whatever?
  end
  

  to compare
  ; compare the shape of the two flipped cards
  ifelse (ask first flippedcard [shape]) = (ask last flippedcard [shape])
     [?whatevershouldhappen_ifmatch?]
     [?whatevershouldhappen_ifnomatch?]
  ; reset the list of flipped cards to "empty"
  setflippedcards [ ]
  end

    Hello Forum!
  Here attached a project using turtlesown instruction.
  1. Why there is an error message about it?
  2/ How can I build a procedure that check if after clicking 2 cards- their 
shapes are the same, If not - it turned side, till we guess all the pairs in 
the game.
  I tried to use the values of turtlesown , but it didnt work.
                     Thanks, Zehava Wizman
