local part1 = -- Path in workspace to your first part
local part2 = -- Path in workspace to your second part

part1.Touched:Connect(function(hit)
    if hit.Parent.Name == part2.Name then
        print(part1.Name .. " hit " .. part2.Name "!")
    end
end)

Why are you checking the parent’s name? You could check the part’s name, or check the part itself

Correct function (with tbe variables @MJTFreeTime used)

part1.Touched:Connect(function(hit)
    if hit == part2 then
        print(part1.Name .. " hit " .. part2.Name "!")
    end
end)

Checking the part’s parent would only be useful in the event that you need to check if the one touching the part is a character.

Ah okay, I was in the thought process used when working with players, not singular parts (whoops lol). And also, I’m simply wary about using == with instances, as I don’t know how the Roblox engine handles boolean comparisons between them; thus, assuming unique names to all parts, comparing names was simply a safer bet (but it probably works fine then).

Here’s a way of doing it that will work for a near infinite amount of parts:

local parts = {
    part1 = -- Path in workspace to your first part
    part2 = -- Path in workspace to your second part
    part3 = -- Path in workspace to your third part
    -- etc.
}

local debounce = false
local partBeingTouched
local partTouched

while true do
    for i, part in pairs(parts) do
        local touchingParts = v:GetTouchingParts()

        for j, touching in pairs(touchingParts) do
            if touching == part and not debounce then
                print(part.Name .. " touched " .. touching.Name "!")
                partBeingTouched = part
                partTouched = touching
                debounce = true
            elseif touching == part and debounce and (touching ~= partTouched or part ~= partBeingTouched) then
                print(part.Name.. " touched " .. touching.Name "!")
                partBeingTouched = part
                partTouched = touching
            else
                debounce = false
            end
        end
    end
end

This way, let’s say OP has 1000 parts and wants to check for any time any of those parts collide with each other. It will loop through all the parts in the array, then loop through all the colliding parts and compare them to the parts in the array. I also included a debounce so that it won’t print 100000000 times a second (exaggeration); however, I also included simple logic that will make the script print again if the parts switch to colliding with different parts, so that it won’t miss any changes. It might be overkill, but perhaps it can help in learning different methods as well.

I hope I helped! And feel free to point out anything wrong with the above.

Is it possible to make a event fire when a part touches another part?

Comparing a variable to an instance works perfectly well. You can test this by putting this code inside a new baseplate:

local Part = workspace.Baseplate if workspace.Baseplate == Part then print("True")  end

Ah okay, thanks for the clarification; though I already accepted that method in my previous post, and used it in the code.
