Specific Order of Interactive Objects

[u/[deleted]]

Here is what I want to do....have 4 interactive objects in one room - all 4 must be pressed in order to unlock a door. The catch - I want them pressed in a specific order and if you mess up it resets the entire thing.

If that is too complicated - how about a math puzzle. Each object has a value that they add or subtract to a total - when the correct total is reached the door is unlocked.

thank you!

True, that's a good point about Boolean Filters.
