Hey. i can’t really explain it in the tile but here it goes.
i need to attribute a random number between 1 - 4 to these Int’s
BUT and here’s what’s bugging me. they can’t be repeated… so if PU Dirt [INT] get’s 1, PU [STONE] cannot get stone as well. and if PU GOLD get’s 3 the others can’t get 3.
any easy way to do this?
Here’s one way:
You could have an integer array with 4 entries (1,2,3 and 4), then shuffle that array, and then assign your variables the shuffled values from the array.
Hah, didn’t realise someone else would also post a solution a minute before me!
Well, I guess you’re spoiled for choice now. 
I would go with Zero, seem far simpler than mine 
What about you make int array of: 0,1,2,3
Then you get random number that from 0 to " valid index)
Read value inside, its your new random value for item
Then you remove item with that rolled index.
Repeat until array is empty.
