I need help with coding a max range for my elemental game. Does anyone know how?

I've been trying to figure out what do to when the mouse is out of the max range for the fire shower thingy. The question I wanted to ask is how do I code, for example, when the mouse goes out of the max range it'll just set the position of the fireshower to the direction of the mouse but on the border of the max range. I hope I explained it clearly because I don't know if I did. Here's the whole script below:

wait(4)
script.Parent.Ferid.OnServerEvent:Connect(function(Player, Mouse)
	local maxrange = 50
	script.Parent.Parent.Parent.Data.Tries.Value = script.Parent.Parent.Parent.Data.Tries.Value + 30
	local AlreadyTouched = false
	local Character = Player.Character or Player.CharacterAdded:wait()
	local torso = Character.UpperTorso
	local Shower = game.ReplicatedStorage.FireShower:Clone()
	Shower.Parent = game.Workspace
	for i,v in pairs(Shower:GetDescendants()) do
		if v:IsA("Part") then
			local distance = (Mouse.Position-torso.Position).Magnitude
			if distance < maxrange then
				v.CFrame = v.CFrame + Mouse*Vector3.new(Mouse.Position,Mouse.Position,Mouse.Position)
			else
				--code when it's out of maxrange should be put here
			 end --This part's the line of code that controls the shower's position.
	end
		v.Touched:Connect(function(hit)
	if hit.Parent.Name ~= nil then
		
		local yo = hit.Parent:findFirstChild("Humanoid")
		if yo == Character then
			yo.Health = yo.Health - 0
		elseif hit.Parent.Name ~= nil and hit.Parent ~= Shower:GetDescendants() then
			local tween = game:GetService("TweenService")
			local boom = TweenInfo.new(1,Enum.EasingStyle.Linear,Enum.EasingDirection.Out,0,false,0)
			local boomprop = {Anchored = true;CanCollide = false;Transparency = 1;Size = Vector3.new(48,48,48) }
			local ew = tween:Create(v,boom,boomprop)
			ew:Play()
			wait(1.5)
			Shower:Destroy()

	end
		end
	end)
	end
	end)

just use magnitude which returns the length of a vector so you could subtract 2 vectors and get the length between them.

ex

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local maxRange = 50 -- max range of 50 studs
local distance = (mouse.Hit.Position, character.HumanoidRootPart.CFrame.Position).Magnitude

if distance <= maxRange then -- if the distance is less or equal to the max range then
	print("in range!!!!")
end
