Random scene selection except for the one you're currently on

msx88

I’ve got a random scene selection between 3 and 21 but I was wondering how I could tell it to not select the one that you’re currently on.

Is there a way to say “randomly select between scenes 3 and 21 except for scene __” ?

I’ve found a couple of similar threads from the past on this subject but they didn’t work for me.

Thanks in advance.

Thanks to @Socks for this...

If you wanted a number between 3 and 21 except 17 (for example), you would use this expression:

(17+random(0,19))%21+1

Which results in these possible values:

(17+0)%21+1=18
(17+1)%21+1=19
(17+2)%21+1=20
(17+3)%21+1=21
(17+4)%21+1=1
(17+5)%21+1=2
(17+6)%21+1=3
(17+7)%21+1=4
(17+8)%21+1=5
(17+9)%21+1=6
(17+10)%21+1=7
(17+11)%21+1=8
(17+12)%21+1=9
(17+13)%21+1=10
(17+14)%21+1=11
(17+15)%21+1=12
(17+16)%21+1=13
(17+17)%21+1=14
(17+18)%21+1=15
(17+19)%21+1=16

For a different exception value, just change the 17 in that expression to something else. So for example, to exclude 6, the expression would be:

(6+random(0,19))%21+1

Thank you so much for your help @tatiang and @Socks, you guys rock.

I've tried the (17+random(0,19))%21+1 expression and yes, it never picked Scene 17 but it did pick up Scenes 1 and 2 which I'm trying to avoid. I was wondering how I can exclude those as well.

So I played around with it a little bit and tried something like (17+random(3,19))%21+1 but it still ended up picking 1 and 2. What kind of modification to the code would work?

In essence, I would like to have random scenes between 3 and 21 picked, but exclude scenes 1, 2 and the current scene I'm on (for ex. 6). I've attached a sample screen shot.

Thanks in advance.

((6-3)+random(1,18))%19+3

Sorry, I forgot your initial requirement for 3 as the minimum.
