who can help implement mixing in an array of numbers. I have 15 numbers and they need to take 15 but not in order.

I tried using a random function but sometimes it happens that the numbers are repeated.

Sorry for my English.
Thank you in advance for your answers \ suggestions.!!

SetRandomSeed(timer()) place that command in your menu code, and have it trigger when you tap the screen. timer() works by keep track of the amount of time that has elapsed since the application started, by having the user tap the screen this adds an unpredictable element that seeds the random number generator with a new random number.

You can actuallly "shuffle" the array.

Pick two random elements. Swap the values. Repeat 100 times.

Your array is shuffled!

Here's some AppGameKit code...

What prevents the random numbers from being the same, and thus swapping itself?
How many times out of the hundred do you think it would happen?



What if the 100 times was random in a range of 100 to 200?

The way I would do it (but I'm not sure of the coding or whether it's most proficient) would be:

1/. Create an array
2/. Create a duplicate array
3/. Shuffle from the first array and put in second
4/. Pick a random array field from second
5/. Check whether that field holds a number that's not being used (say 999)
6/. If it doesn't, do whatever you going to do with it then put 999 in it.
7/. Goto 4 unless it contains 999
8/. If that particular field that was randomly chosen contains 999, choose another (goto 4).

Does that make sense?

Although the odds are against it, it would be entirely possible to run the loop 10,000 times, and end up with the values in the same order they started in. That would qualify as a random result as well.
