  • Hi there,

    This is my problem:

    I have an array containing a combination of values, say 1 a, 2 b, 3 c, 4 d and 5 e (in my case, the numbers are clients and the alphabetics are characters in my game)

    Now i want to create new combinations of clients and characters where no combination may be already present in the current array.


    1a, 2b, 3c, 4d, 5e may result in 1b, 2a, 3d, 4e and 5c but not in 1b ,2a,3d,4c,5e (5e already exists).

    Please help.

    I need to execute these steps multiple times per game session, but it is enought to check against the last created combinations.

  • Basically the logic would be :

    copy array1 to array2

    shuffle array2

    compare array1 to array2

    and if any two values are the same repeat the shuffle

    A partial look of how the loop should look is this:

    | while                                          |
    	local variable again=0
    	|                                            | shuffle array2
    	| array: for each x                          | set again to 1
    	| array: current |
    	| again=0                                    | stop loop
    You can find ideas of ways to do the shuffling elsewhere on the forum.
