Random with no repeats

Now I know there is already a thread on this but I kind of wanted a visual representation of it so can something tell me how to generate 4 random numbers with no 2 numbers same?

I threw this together quickly for you

I use Globals to track my randoms, each on can be 1-10 (This is done by the Random1through10 Function)

I set all values to 0 every time I run the function - clearing any old numbers

Then I call my function 4 times to generate 4 numbers.

One by one I set my Globals, which means if NoRepeat1 is 0 then I haven't set any and NoRepeat1 is allowed to be any random I roll

The 2nd time the function runs NoRepeat1 wont equal 0 so it will go to the else NoRepeat2 equal 0. Now I need to verify NoRepeat2 is not the same as NoRepeat1. If it is the same I reset the value to 0 and run the function again. Which will make it to the same block and attempt again. If it's true I move on to NoRepeat3 which then checks the previous 2 in the same fashion. Last I check 4 against the previous 3.

Obviously this will get gross when trying to do more than 4 numbers but it will work for your case and you dont have to worry about Arrays ;)

Thanks a lot!

winstreak That's super complex and extremely ineffective solution. What would you do if you need 20 random numbers?

There is a feature called "permutation table" in the official AdvancedRandom plugin. It's pretty easy to use. Here is an example of getting 4 non-repeating numbers in the range from 1 to 10:

Is it possible to use a "probability table" to get 2 non-repeating valor too?

Of course.

AdvancedRandom.Permutation(0) will give you the first random number.

AdvancedRandom.Permutation(1) will give you the second random number.

AdvancedRandom.Permutation(999) will give you the 1000th random number.
