For example you want to do a clickdetector on getting a fake passport, you may load an explorer and find whether an object has a clickdetector.

So if you find a clickdetector in the workspace then you locate it, and you see it is in game.Workspace.Signs.Other.GiveFakePassport
then you run GetDescendants()
for it using a for loop
and find whether its descendants has a clickdetector. As it finds one of its parts has a clickdetector you just run fireclickdetector(clickdetector here)
to click it. You could even make an autofarm for it if you are a good lua scripter.
