Creating a "safe" that can be unlocked

[FormerTGFGuy]

I want to have a safe in my game where you have to enter the correct # sequence to open it. What's the best way to do this? I want a visual display of the numbers you're entering. Should I just use a fancy counter, or is there a better way or a different object I should use?

You could have 4 counters (or however many you want) with an up arrow above and a down arrow below each one. Make it so that when you hit the up arrow, it adds one to the corresponding counter, and click down to subtract. In the event editor, make it so that when all the counters equal the correct digit, it unlocks the safe.
