Weird error with the destroy() function

Help and Feedback Scripting Support
#1

I am creating a laser projectile, but there’s a problem: I cannot destroy the laser.
I open the dev console and it said:

Workspace.laser.laserTouched:8: attempt to index nil with ‘Destroy’

I don’t get why I am getting this error.

script.Parent.Touched:Connect(function(hit)
	if hit.Name ~= "laser" and hit.Name ~= "Body" and hit.Name ~= "Right Arm" then
		script.Parent:Destroy()
	end
	if hit.Parent:FindFirstChild("Humanoid") then
		hit.Parent.Humanoid.Health -= 20
		hit.Parent.Humanoid.Sit = true
		script.Parent:Destroy() -- Here is the error
	end
end)

Try :Remove() instead of using :Destory()

:Remove() removes it from the datamodel by setting the parent to nil. It requires passive garbage collection to remove from memory. If you have a reference to it anywhere, it will remain.

:Destroy() also locks the Parent and destroys connections and calls. It is more complete.

I have had similar issues with :Destroy() with touched events. It ended up being a race condition. The server was trying to destroy the same object multiple times and of course that can only be done once.
