You will need at least 2 buttons
Property Device
Barrier
Triggers equal to the amount of buttons optional Pop up device x2 for letting the player know if they got the code right or wrong.
So first, you will set up the area. I personally used metallic dark for walls and metallic light for floor.
So you want to make it so the buttons disable after being pressed.
the only values you need to change are the actual property numbers.
The 2nd image is for the last button.
So in the end it should look similar to this but with the amount of buttons and triggers you chose
You could just use a questioner with a specific kit hooked to a barrier since it’s much simpler.
Optional:
You can use numbers instead and if you get the first digit correct, you move on to the next one.
nice job
