how to print something when someone touches a part?

Help me please! I want it to print; "A cookie!"

Hello! Here is a script!

wait()

function onTouched() --Making a function and giving it a name 
	wait() --Adding this so it doesn't print "A cookie!" right as you join it
	print("A cookie!") --Printing "A cookie!" 
end

script.Parent.Touched:Connect(onTouched) --Calling the function and event.

Hope this helped you!

If this helped don't forget to accept the answer! :)

As you probably know by now, baseparts have a built in Touch function that has the part that touched it as an argument and lua has a print function so basically you can do this:

script.Parent.Touched:Connect(function(hit)
	print("A Cookie",hit)
end)

But we can spice up this touched function with a bit extra

for one we could have it only work when a player touches it with the built in :GetPlayerFromCharacter() function.

script.Parent.Touched:Connect(function(hit)
	if hit and hit.Parent and game.Players:GetPlayerFromCharacter(hit.Parent) then
		print("A Cookie")
	end
end)

But this function has some flaws, like printing "A Cookie" every time a body part touches the parts, so we can either use a debounce or a whitelist

--[[
Option 1:
Debounce
]]
local debounce = false
script.Parent.Touched:Connect(function(hit)
	if hit and hit.Parent and game.Players:GetPlayerFromCharacter(hit.Parent) then
		if not debounce then
			debounce = true
			print("A Cookie")
			wait(2)
			debounce = false
		end
	end
end)

--[[
Option 2:
Whitelist
]]
local hithums = {}
script.Parent.Touched:Connect(function(hit)
	if hit and hit.Parent and game.Players:GetPlayerFromCharacter(hit.Parent) then
		if hit.Parent.Humanoid and not hithums[hit.Parent.Humanoid] then
			print("A Cookie")
			hithums[hit.Parent.Humanoid] = true
			wait(2)
			hithums[hit.Parent.Humanoid] = false--nil works also
		end
	end
end)
