How do I stop a function

[sp00kface]

Basically I need help stopping a function that won’t stop running. Once I fire this function it wont stop running, it doesn’t end whatsoever. I put checks in place and it just doesn’t stop. I also tried using return and break, but I am not quite familiar with them.

The script is just a simple raycast script that makes a part that stretches from the players head to their mouse.
Here is the script:

function laser(no)
	if no == false then
	if player.Character.Humanoid.Health > 0 then
			local mouseray = cam:ViewportPointToRay(mouse.X, mouse.Y)
			local raycastresult = workspace:Raycast(mouseray.Origin, mouseray.Direction * 1000, rayparams)
			local part = Instance.new("Part")
			part.Anchored = true
			if raycastresult then
				print(raycastresult)
				part.Parent = workspace
				part.Position = player.Character.Head.Position
				part.CanCollide = false
				part.CFrame = CFrame.lookAt(part.Position, raycastresult.Position)
				local mag = (raycastresult.Position - player.Character.Head.Position).Magnitude
				part.Size = Vector3.new(1,1,mag)
				part.CFrame = part.CFrame * CFrame.new(0,0,mag/-2)
				local explosion = Instance.new("Explosion")
				explosion.Parent = workspace
				explosion.Position = raycastresult.Position
			end
		end
	end
end

uis.InputBegan:Connect(function(input)
	local fired = false
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		if fired == false then 
			laser(fired)
			print("hi")
			fired = true
			wait(3)
			print("hi2")
			fired = false
		end
		
	end
end)

Return stops the function and optionally returns something
Examples:

    function func()
          print("Start")
          return
          print("this would probably error")
    end

function addTogether(... : number) --variadic function (basically has an infinite number of arguments of type number)
	local numbersToAdd = {...}
	local sum = 0
	for i, number in pairs(numbersToAdd) do
		sum += number
	end
	return sum -- stops and returns or outputs the sum
end
local importantNumber = addTogether(6, 9, 4, 2, 0)
print(importantNumber)

Also when do you want it to stop?

You can wrap it into a thread.

i figured it out, the function wasn’t looping. i just put the fired statement inside the function, so it kept switching to false. Thanks for explaining return tho.
