Calling script from local script?

I have made a local script that makes a ball and shoots it out from your upper torso (R15). The tutorial made a damage script and called it from the local script. The tutorial is out of date and will not work. So how can I call a damaging script, as well as how to make one? thanks for the help.

	local S = script["Script"]:clone()
	S.Parent = x
	
	x.Parent = workspace
	wait(2)
	
	x:remove()
	
end

end)

Use remotes, the code rn is a mess so I can't really write it out back, sorry!
