Question Having Trouble With Buttons: Index Out of Range Exception

Hello ya'll, I'm a novice Unity user and I've run into a problem whilst trying to make a simple tic tac toe project. Maybe someone can help me.

I have a grid object with 9 child buttons, the script is supposed to put a sprite on the button when it's pressed, set that button to be non-interactable, and change my 'whoturn' variable to the other player's turn.

When I push one of the buttons I'm getting an IndexOutOfRangeException in the console. It seems to be a problem with the WhichNumber code in my script. I've attached a couple screen shots of my settings for these buttons; I have those buttons assigned to my game controller object in in the inspector, and I set the On Click options correctly (I think) on each button. The screen shot shows button 0, but the other ones go from 1-8 depending on their location on the grid, if that makes sense.

I'm sure this is an extremely simple problem, but I'm a beginner and I'm at a loss. Any advice?

Thanks in advance!

 

You have two GameController scripts on your object. Remove one of them, probably the one where the "tictactoe spaces" array is empty.

 

Yep, I definitely didn't notice I had done that. Problem solved, thank you!
