Tic-Tac-Toe detecting 3-in-a-row programming

[Taro]

Hello,

I've been developing a Tic-Tac-Toe game using Gamemaker. I have a problem with detecting if any 3 'X' makes a diagonal, column, or row. Here is the simplified code for taking turns between 'X' and 'O'.

Information about object: obj_?

Sprite: spr_?
Solid: false
Visible: true
Depth: 0
Persistent: false
Parent: <no parent>
Mask: <same as sprite>

Create Event:
set the score to 0
set the information in the window caption:
 show score with caption _turns: 
 don't show lives with caption _Lives: 
 don't show health with caption _health: 

Mouse Event for Left Pressed:
set the sprite to spr_?_3 with subimage image_index and speed 1

Mouse Event for Right Pressed:
set the sprite to spr_?_3 with subimage image_index and speed 1

Mouse Event for Left Released:
if score is equal to 0
      change the instance into object obj_x, not performing events
      set the score to 1
else
      if score is equal to 1
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 2
      change the instance into object obj_x, not performing events
      set the score relative to 1
else
      if score is equal to 3
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 4
      change the instance into object obj_x, not performing events
      set the score relative to 1
else
      if score is equal to 5
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 6
      change the instance into object obj_x, not performing events
      set the score relative to 1
else
      if score is equal to 7
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 8
      change the instance into object obj_x, not performing events
      set the score relative to 1
else
      if score is equal to 9
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>

Mouse Event for Right Released:
if score is equal to 1
      change the instance into object obj_o, not performing events
      set the score relative to 1
else
      if score is equal to 2
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 3
      change the instance into object obj_o, not performing events
      set the score relative to 1
else
      if score is equal to 4
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 5
      change the instance into object obj_o, not performing events
      set the score relative to 1
else
      if score is equal to 6
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 7
      change the instance into object obj_o, not performing events
      set the score relative to 1
else
      if score is equal to 8
      save the game in the file savegame
      go to room rm_warning with transition effect <no effect>
if score is equal to 0
      display message: Other user goes first in this mode.

Mouse Event for Mouse Enter:
set the sprite to spr_?_2 with subimage image_index and speed 1

Mouse Event for Mouse Leave:
set the sprite to spr_? with subimage image_index and speed 1

One suggestion I was thinking about was to create an object overlay in the specified room, then program a collision with an isolated, differential object.
I would additionally appreciate any C, C#, or C++ coding as well.

x= obj_1
y= obj_2
z= obj_3
...
then
game_end()

I was trying to say that object one collides with x at a certain point, then convert it to a number, each assigned to a different point in the room.
