How do I prevent a trivia game from showing duplicate questions?

Hi,

I'm building a trivia game based off of this tutorial: construct.net/en/tutorials/trivia-game-929/page-2

I've customized the events a bit, but basic functionality for pulling random questions is the same. However I'm having trouble figuring out how to prevent it from pulling the same question more than once.

Right now the game pulls a random question and displays it, but sometimes it will pull the same question up 2 or 3 times in a single game, which isn't ideal.

I did some searching and learned that I could have a question deleted after it was shown, so it wouldn't be pulled up more than once:

(-> QuestionArray: Delete index randomNumber from X axis)

But when I put that code in only the first question shows and then the rest are blank.

Then I found info that said I should reduce the width of the Array by 1 to have the Array table resize to where it wouldn't pull blank spaces where answers used to be:

(-> QuestionArray: Set size to (-1, 1, 1))

But it didn't work. So I'm stumped and wondering if anyone else has any insight. This is day 2 after searching & trying different things & reading the manual.

The array method should work, but you could also use a permutation table from the Advanced Random object so you don't need to rebuild the array.

Hope this helps...

Cheers!

Thank you, but I'm having trouble understanding that. I'm still new to Construct so maybe its a little over my head.
