How to write a function that places pieces on a tictactoe board in a GUI.

what i have so far for this function is this:

function handles = buttonPress(hObject,handles)

if handles.(hObject.Tag).String == ''

      if handles.turnNumber ==1
          handles.(hObject.Tag).String = 'o'
      else
          handles.(hObject.Tag).String = 'x'
      end
  end

end

I just don't understand what it even does. I am so lost. Please help

rayray - did you write the above code or "borrow" it from someone else? If you wrote it, then how come you don't understand what it does? You must have more than the above code because this function on its own isn't sufficient for your GUI.

This seems like a homework assignment since others have posted similar questions (with near identical code) in this forum, so you may want to start over. Design your GUI first (with the nine controls for the tic-tac-toe board) and then worry about the behaviour when you press each control (i.e. button on the board).

My TA literally told me what to write and said that this was enough of a start for me to understand what to do and understand it all on my own. I do have a lot more of it but I am not sure if that would be a good idea for me to post all of it.

Are you calling the buttonPress code from your pushbutton callbacks? (Or whatever controls you are using for the cells in the 3x3 board.)

I think that the above code is missing some logic - how do you know if you should draw an X or O? Why is the turnNumber one? What does this represent?
