[Request] Various Puzzles

[Doctor Professor Nikolai]

Hi, I was wondering, can someone help me make puzzles in game? Heres an example of one I need to make:

There are two switches, you need to stand on them both to open the door, and there is a boulder.

You can push the boulder onto one of the switches, and it will go down, and you stand on the other one.

How can I do something like that?

Use variables for the boulder's x and y value.

Then, if x = switch x value and y = switch y value, door opens.
