Hi everyone!
I have a widget called handler with a horizontal box, I can populate this box with 3 other widgets, the problem is that when I randomly choose these 3 widgets sometimes 2 or 3 of them appear the same and I would like to avoid this happening to me.
This is my function for the random int, but it doesn’t remove the duplicates, does anyone have an idea how I could solve it?
Thank you.
• Shuffle the array and grab the first 3. No need to remove anything.
• the function terminates early, the loop never loops
• be mindful of pure function evaluation, the script generates 2 different random values since the node is accessed twice
Thanks for the reply! I had no idea that the shuffle node existed, I tried to do some tests, and although it seems simple I can’t do it.
I would like to make a small correction to the image I shared, it was a screenshot of modified function so I don’t use the for loop inside the function due its doing nothing (at least it seems) but I use for loop on event pre construct of a menu, so the nodes I’m currently using are composed as follows:
On pre construct i have something like this
And the function (pure or not) was like this:
Even using shuffle instead of random doesn’t change much, furthermore I find it difficult to understand how to take only 3 names from shuffle if it doesn’t have an integrated output node.
So what exactly are you trying to do? Run a function once and have it return 3 non-repeating Data Table entries?
Yes, exactly 
We generate 3 entries 
, and use the return value to operate on them 
:
Alternatively:
But it’s generally more convenient to have functions do 1 thing. One generates data, the other populates something with the generated data. Handy when things grow in scope, and they always do.
Thank you!!!
I had been trying for days, but without an exact logic I would have continued to wander endlessly.
You deserve the crown you wear!
