Is there a function that would start when two parts touch?

So for example if you had part1 and part2, and you want something to happen when the two parts touch, is there a function for that? kind of like the onTouched function but i'm pretty sure that one only works when a humanoid touches the object. Thanks for any help guys!

OnTouched works for anything. It does not have to be a humanoid.

So:

part1.Touched:connect(function(hit)
	if hit == part2 then
		print("Part1 was touched by Part2")
	end
end)

The touched event fires on anything that hits it. Keep in mind it's called Touched and not onTouched!

Part1 = workspace.Part1
Part2 = workspace.Part2

Part1.Touched:connect(function(Hit)
	if Hit == Part2 then
		print("Hit")
	end
end)
