this is what i have, it dosn’t fire the part but spawn it, how would I shoot it out in a straight line?

local UIS = game:GetService("UserInputService")
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local camera = workspace.CurrentCamera
local Player = Players.LocalPlayer
local pathToThePart = ReplicatedStorage.Part

UIS.InputBegan:Connect(function(Key, Chatted)
	if Chatted then
		return
	end
	if Key.KeyCode == Enum.KeyCode.E then
		local projectile = pathToThePart
		projectile.Parent = workspace
		projectile.CFrame = Player.Character.HumanoidRootPart.CFrame
		projectile.BodyVelocity = Player.Character.HumanoidRootPart.CFrame.lookVector * 10
	end
end)
