Returning nil value

Help and Feedback Scripting Support

I’ve been making this gun system for a bit of time and I’ve gotten pretty far. My friend gave me the idea to make it stop lagging so far behind when you shoot it, so I decided to make the visual stuff render on the client from a server script.

The issue with it is I send the barrel of the gun (CFrame) to the server, and the server sends it to the client using FireAllClients and it stops at the second line of code. It repeats the following: “Attempt to index CFrame, got nil” and same thing when I tried to use WaitForChild in both the main, and visual scripts.

--Main local script
local tool = script.Parent
local muzzle = tool:WaitForChild("Barrel") 
local enabled = false --I already made a function that checks if the tool is equipped, so ignore this.

mouse.Button1Down:Connect(function()
	if enabled == true then
		local raycast = workspace:Raycast(startingpos, (mouse.Hit.p - startingpos).Unit *300,rc)
		if raycast then
			print("Shot")
			game.ReplicatedStorage.GunFE.Visual:FireServer(mouse.Hit.p, muzzle)
			local result = raycast.Instance.Parent or raycast.Instance.Parent.Parent or raycast.Instance.Parent.Parent.Parent
			if result:FindFirstChild("Humanoid") ~= nil then
				local newplr = game:GetService("Players"):GetPlayerFromCharacter(result)
				if result.Team ~= plr.Team then
					game.ReplicatedStorage.GunFE.Shot:FireServer(result:FindFirstChild("Humanoid"),damage)
				end
			end
		end
	end
end)

--Server Script
game.ReplicatedStorage.GunFE.Visual.OnServerEvent:Connect(function(plr, mouse, barrel)
	game.ReplicatedStorage.GunFE.Client:FireAllClients(mouse,barrel)
end)

--Visual local script
game.ReplicatedStorage.GunFE.Client.OnClientEvent:Connect(function(plr, mouse, barrel)
	local newpos = barrel.CFrame.p 
	print(newpos)
	local bip = (mouse - newpos).Unit * 300
	local dir = newpos + bip/2
	print(dir)
	local bullet = Instance.new("Part")
	bullet.Parent = workspace
	bullet.Color = Color3.fromRGB(255,255,0)
	bullet.Material = Enum.Material.Neon
	bullet.Anchored = true
	bullet.CanCollide = false
	bullet.CFrame = CFrame.new(dir, newpos)
	bullet.Size = Vector3.new(.3,.3,dir.Magnitude)
	game:GetService("Debris"):AddItem(bullet,0.05)
end)

I’ve searched through each script and made various edits, but it is apparent that I am missing something. Not sure why it is returning a nil value each time.

Maybe because you’re passing (mouse, barrel) to the clients and on the client you have (plr, mouse, barrel) instead of (mouse, barrel)

I feel a lot dumber now that I realize that passing the player over to the client from a server is just redundant.
