Memory game problem: comparing consecutive numbers in a list

[teemflmngo]

I have a simple memory game where the cards are number consecutively, shuffled and arranged face-down on the stage. I can test for the same card and get a positive result, I can test for different cards and get a positive result, and I can test to see if the first card flipped is larger or smaller than the second card.

What I think I want to do is flip _selectedCards[0], see if it is an even or odd integer, then flip _selectedCards[1] and check with the first. If _selectedCards[0] is odd, I would want to check that _selectedCards[1] is the card number immediately preceding _selectedCards[0]. if _selectedCards[0] is even, I would want to check that _selectedCards[1] is the next number. In other words, cards numbered 0 & 1 match, 2 & 3 match, etc...

My current if statement only checks for the same card and is as follows:

if (_selectedCards[0].cardNumber == _selectedCards[1].cardNumber) {

I just don't know enough code to write what I want. Thanks.

Hi,

please check the following this may help you out.

// let say selCard is the card that was clicked first
// let say checkCard is the card the was clicked second.
// so we would compare whether checCard is the correct card on the basis of selCard being even or odd.

// check wether the selCard is Even on Odd
// i.e if divisible by 2 its even else odd
var even:Boolean = ((selCard.cardNumber % 2) == 0);

// if the selCard is even
if (even) {
if (checkCard.cardNumber == (selCard.cardNumber + 1)) {
trace("Success, Card matched");
}else {
trace("Cards dont match");
}
}else {
// if the selCar is odd
if (checkCard.cardNumber == (selCard.cardNumber - 1)) {
trace("Success, Card matched");
}else {
trace("Cards dont match");
}
}
