Random except for previous number
Hi all,
This sounds a bit silly bit after having searched for 3 hours I have given up!
I want random numbers in my patch, so I used random. But I don't want the same number twice. I want the number to be a different number than the random number generator has already given. (I can't use the "urn" function here because for instance if it has given number 1 it must give 2 or 3,4,5 etc. and if it has given 5 it must be able to give 1 again as a possible output (but not 5!))
Hope I was clear!
Thanks!
not sure I get it 100%, but did you look at [urn-jb] ?
Yes you are right! It did the trick. Thanks!!
Another approach I had floating around (maybe slightly more random):
Here's a general technique that I think does what you want.
Suppose you want a series of random numbers between 1 and n, where each one is different from the last one.
For the first number, just pick one between 1 and n. Remember it.
For each number after the first, pick a number between 1 and n-1. If the number is >= the one you remembered, add 1; otherwise use it unchanged. Replace the remembered number by the new one.
I would think this could be done with no more than a handful of objects.
1. compare every output with the previous one using [==]
2. if repetition is "true", just trigger the random generator again.
