Checking variable values of nodes in a group? (Tic Tac Toe logic)

SnapCracklins

So I am working on Tic Tac Toe logic and practicing using groups. I have an array acting as a state machine to handle whether a button is empty, has_x or has_o. (0,1,2 in the index to be specific). This part of my logic works great and it's all running off only two very short scripts.

I have the buttons sorted into arrays to check for their variable values. My goal is to see if their local state variable either has_x or has_o to determine the win. (Yes, my singleton is named StateMachine but it is not the machine, I ended up doing that local because it made sense for the smaller objects in this app).

My arrays, sorted at ready:

onready var myButtons = get_tree().get_nodes_in_group('all_buttons')
onready var row1 = get_tree().get_nodes_in_group('row_1')
onready var row2 = get_tree().get_nodes_in_group('row_2')
onready var row3 = get_tree().get_nodes_in_group('row_3')
onready var column1 = get_tree().get_nodes_in_group('column_1')
onready var column2 = get_tree().get_nodes_in_group('column_2')
onready var column3 = get_tree().get_nodes_in_group('column_3')
onready var across1 = get_tree().get_nodes_in_group('across_1')
onready var across2 = get_tree().get_nodes_in_group('across_2')

And each button has this variable and array:

var stateMachine = ["EMPTY", "HAS_X", "HAS_O"]
var state = stateMachine[0]

So what I am trying to do is check if the local variable "state" shares a value across a group.

var xButtons = 0
var oButtons = 0:

for button in row1:
	if button.state == button.stateMachine[1]:
		xButtons++
	elif button.state == button.stateMachine[2]:
		yButtons++
if xButtons == row1.size():
	print("x wins")
if yButtons == row1.size():
	print("y wins")

I might have gotten some syntax wrong there, but you get the idea.

The logic works but my implementation does not. However, you taught me something and that's what important. I'll keep at it. I am certainly doing something wrong in my loop.

UPDATE: Finally! While the button math worked, something about my setup didn't - because I used arrays. :#

After some debugging and experimenting, I found it works better to load the values into an empty array and then do that goal comparison that you showed me. The array gets called empty every time it is called so that handles errors and false wins.

Thank you again for the advice. If anyone is interested in TicTacToe working in 150 lines, I'll post that code in projects. It really helps with learning arrays and groups.
