Attempt to index nil with Position - lua

Question

I'm trying to do something like a spear throw and I'm so confused. It says:
ServerScriptService.FireMagic.FireSpear:16: attempt to index nil with 'Position'
Anyways, here's the LocalScript code:
wait(1)
local Player = game.Players.LocalPlayer
local Character = Player.Character
local Mouse = Player:GetMouse()
local rp = game:GetService("ReplicatedStorage")
local FireSpear = rp:WaitForChild("FireRemote")
local UIS = game:GetService("UserInputService")
local debounce = true
local cd = 10
UIS.InputBegan:Connect(function(input, isTyping)
if isTyping then
return
elseif input.KeyCode == Enum.KeyCode.E and debounce and Character then
debounce = false
FireSpear:FireServer()
wait(cd)
debounce = true
end
end)
and the Script:
wait(1)
local rp = game:GetService("ReplicatedStorage")
local ss = game:GetService("ServerStorage")
local Debris = game:GetService("Debris")
local ssFireSpear = ss.FireMagic:WaitForChild("ssFireSpear")
local FireRemote = rp:WaitForChild("FireRemote")
local UhTable = {}
local function LookatMouse(Mouse, RootPart)
local bodyG = Instance.new("BodyGyro")
bodyG.MaxTorque = Vector3.new(0, 500000, 0)
bodyG.P = 10000
bodyG.CFrame = CFrame.new(RootPart.Position, Mouse.Position)
bodyG.Parent = RootPart
Debris:AddItem(bodyG, 1)
end
local function MoveTowardsMouse(Mouse, Main)
local bodyV = Instance.new("BodyVelocity")
bodyV.MaxForce = Vector3.new(500000, 500000, 500000)
bodyV.Velocity = CFrame.new(Main.Position, Mouse.Position).LookVector * 100
bodyV.Parent = Main
local bodyG = Instance.new("BodyGyro")
bodyG.MaxTorque = Vector3.new(500000, 500000, 500000)
bodyG.P = 10000
bodyG.CFrame = CFrame.new(Main.Position, Mouse.Position)
bodyG.Parent = Main
end
FireRemote.OnServerEvent:Connect(function(Player, Mouse_CFrame)
if UhTable[Player.Name] == true then
return
end
UhTable[Player.Name] = true
local Character = Player.Character
local RootPart = Character:WaitForChild("HumanoidRootPart")
local folder = workspace:FindFirstChild("DebrisFolder") or Instance.new("Folder",workspace)
folder.Name = "DebrisFolder"
local RightHand = Character:WaitForChild("RightHand")
local FireSpear = ssFireSpear:Clone()
local Handle = FireSpear:WaitForChild("Handle")
local Hitbox = FireSpear:WaitForChild("Hitbox")
local Mesh = FireSpear:WaitForChild("Mesh")
FireSpear:SetPrimaryPartCFrame(RightHand.CFrame)
FireSpear.Parent = folder
local weld = Instance.new("Motor6D")
weld.Parent = Handle
weld.Part0 = RightHand
weld.Part1 = Handle
Hitbox:SetNetworkOwner(nil)
local function MakeStuffHappen()
spawn(function()
LookatMouse(Mouse_CFrame,RootPart)
wait(.6)
weld:Destroy()
MoveTowardsMouse(Mouse_CFrame,Hitbox)
end)
end
MakeStuffHappen()
end)
I'm following a tutorial but I don't know how the issue got there.

Answer 1

Your error is pointing to the fact that you are trying to reference fields on an object that doesn't exist. In this case, it's the ´Mouse´ object, which you never supplied from the client.
To fix this, pass the mouse information in when you call the RemoteEvent's FireServer() function.
UIS.InputBegan:Connect(function(input, isTyping)
if isTyping then
return
elseif input.KeyCode == Enum.KeyCode.E and debounce and Character then
debounce = false
local mouseCFrame = Mouse.Hit
FireSpear:FireServer(mouseCFrame)
wait(cd)
debounce = true
end
end)
