Creating elevators that can be placed

Okay, I’ll test this. I think the only problem I have now is how the button is going to work. You see, I would hope that I could create a bool value that tells if the button is activated or not. This value has to be in the specific button. I’m trying to let the player use line trace, and if the line hits the button object, and the player presses a key, then this value changes to true for as long as the button is held. Do you think this is possible, even with several different buttons in the level?
