Laser doesn't kill if player is jumping on it?

Hi, I'm a really really bad scripter and I only know basic and easy stuff. When I try to test my game I jump on the laser consistently, it wouldn't kill. This is my script: `~~~~~~~~~~~~~~~~~ debounce = false script.Parent.Touched:Connect(function(hit) if not debounce then

debounce = true
	
	if hit.Parent:FindFirstChild("Humanoid") then
		hit.Parent:FindFirstChild("Humanoid"):TakeDamage(20)
	end

wait(0.5)

debounce = false
end

end)

`
Does it have to be published for it to kill instantly?

I don't really know how to tab the script because i'm fairly new to this site so please don't blame me. Sorry.

This is a better script for a laser, because you don't need to use debounce:

script.Parent.Touched:Connect(function(hit)
	local humanoid = hit.Parent:FindFirstChild("Humanoid") --Checks if there is a Humanoid

	if humanoid then --If there is a humanoid, do following
		humanoid.Health = 0 --Kill player
	end
end)

Hope this helped!
