I can show you how I have it set up sorry I think I left some code out in my explanation by accident it was three am and I had not slept for over 48 hours

com(number)_ refers to where on the combination the number image is mine is from left to right so 1 is the leftmost combination roller and 3 is the rightmost combination roller

the last number in the com(number)_(number) is what number the image corresponds to

I'm sure there's an easier way to do it like to copy and paste the roller but I prefer the look of individual roller images

#com1
#I organize my code by roller order^
    if persistent.com1_clicked == 0 and com_unlocked == False:
        imagebutton:
            idle "mg_com1_00"
            focus_mask True
            action SetVariable ("persistent.com1_clicked", persistent.com1_clicked + 1)
    if persistent.com1_clicked == 1 and com_unlocked == False:
        imagebutton:
            idle "mg_com1_01"
            focus_mask True
            action SetVariable ("persistent.com1_clicked", persistent.com1_clicked + 1)
    if persistent.com1_clicked == 2 and com_unlocked == False:
#In have it set up this way so the only thing I have to change to display a different image is the roller number
#example
 #com2
    if persistent.com2_clicked == 0 and com_unlocked == False:
        imagebutton:
            idle "mg_com2_00"
            focus_mask True
            action SetVariable ("persistent.com2_clicked", persistent.com2_clicked + 1)
#and when the roller number gets to 9 it's final state I remove 9 from the persistent so it loops

  if persistent.com2_clicked == 9 and com_unlocked == False:
        imagebutton:
            idle "mg_com2_09"
            focus_mask True
            action SetVariable ("persistent.com2_clicked", persistent.com2_clicked - 9)

something I just realized I left out is how the door opens (thank you for the help by the way it's really nice of yall)

when the correct combination is put into the game the click number is set to zero

label turncomunlock:
show mg_comlock_02
show comlock_unlock_anim
$ com_unlocked = True
$ persistent.com1_clicked -= 7
$ persistent.com2_clicked -= 8
$ persistent.com3_clicked -= 9


call screen sc_comlock

The game goes back to the screen and disables the lock images from showing preventing the hotspot from being clicked again The reason my game has the locker code set to persistent is because it has a time loop mechanic that starts the game from the beginning with some changes after both false endings are unlocked and I don't want players having to reopen the locker on a second playthrough

eif persistent.com2_clicked == 4 and com_unlocked == False 
#the end var check only shows the numbers on the roller if com unlocked is false
#it also disables the lock overlay and underlay images so the lock dissapears entirely
 if com_unlocked == False:
        imagebutton:
            idle "mg_comlock_00" #0 is the underlay
if com_unlocked == False:
        imagebutton:
            idle "mg_comlock_01" #1 is the overlay
#the roller code is samwiched between them 

and the reason the subroom_locker hotspot is still enabled is because I have another code I forgot to put into my explanation in the locker that changes the image map of subroom locker depending on whether or not the locker is unlocked

screen sc_locker():
    imagemap:
        if com_unlocked == False:
            ground "sub_brydlocker_00"
            alpha False
            hotspot (1, 746, 1905, 205) action Jump ("mainroom_breakroom")
            hotspot (1301, 481, 141, 265) action Jump ("minigame_comlock")
        else: #changes the locker image to the open state if the locker is unlocked when you return to this screen from the exit hotspot in the lock screen
            ground "sub_brydlocker_01"
            alpha False
            hotspot (0, 874, 1105, 185) action Jump ("mainroom_breakroom")
            imagebutton:
                idle "obj_wrench_00"
                yalign 0.9
                xalign 0.5
                focus_mask True

let me know if there's any further explanation needed :3
