Why does my ray only cast once rather than over and over?

I'm making a turret, and I have this script which is supposed to fire at players while they're in it's range. The part named range is the area which people are supposed to be shot if they're touching. The boolean value I have is suppose to do this: If it's true, the ray should keep casting. if it's false, it shouldn't cast. I'm later going to add a script that makes it false if it isn't touching. The issue is, right now it only casts the ray once.

script.Parent.Parent.Range.Touched:Connect(function(hit)
	repeat
	if script.Parent.Parent.Range.Touched then
		if hit.Parent:FindFirstChild("Humanoid") and script.Parent.Value.Value == false then
			script.Parent.Value.Value = true
		    local char = hit.Parent
		    local ray = Ray.new(script.Parent.CFrame.p, (char.HumanoidRootPart.CFrame.p-script.Parent.CFrame.p).unit*1000)
		    local part, position = workspace:FindPartOnRay(ray, script.Parent, false, true)
		    local beam = Instance.new("Part", workspace)
		    beam.BrickColor = BrickColor.new("Royal purple")
		    beam.FormFactor = "Custom"
		    beam.Material = "Neon"
		    beam.Transparency = .25
		    beam.Anchored = true
		    beam.Locked = true
		    beam.CanCollide = false
		    local distance = (script.Parent.CFrame.p - position).magnitude
		    beam.Size = Vector3.new(.3,.3,distance)
		    beam.CFrame = CFrame.new(script.Parent.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
			game:GetService("Debris"):AddItem(beam, .1)
		end
	end
	wait(1)
	until script.Parent.Value == false
end)
