that works whenever, but i want it to only work when you equip a tool and it deactivates when u unequip

#4 
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local plr = Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local mouse = plr:GetMouse()

local armOffset = char.UpperTorso.CFrame:Inverse() * char.RightUpperArm.CFrame

local armWeld = Instance.new("Weld")
armWeld.Part0 = char.UpperTorso
armWeld.Part1 = char.RightUpperArm
armWeld.Parent = char

script.Parent.Parent.Equipped:Connect(function()
	mouse.Icon = "rbxassetid://316279304"

	RunService.Heartbeat:Connect(function()
		local cframe = CFrame.new(char.UpperTorso.Position, mouse.Hit.Position) * CFrame.Angles(math.pi/2, 0, 0)
		armWeld.C0 = armOffset * char.UpperTorso.CFrame:toObjectSpace(cframe)
	end)
end)

script.Parent.Parent.Unequipped:Connect(function()
	mouse.Icon = ""
end)

this is what I have so far but its saying char is nil

Make sure to use a local script, .LocalPlayer only works in local scripts.

here is a modified version that also handles the connection on unequip

Local script inside a tool Instance 
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local plr = Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local mouse = plr:GetMouse()

local armOffset = char.UpperTorso.CFrame:Inverse() * char.RightUpperArm.CFrame

local armWeld = Instance.new("Weld")
armWeld.Part0 = char.UpperTorso
armWeld.Part1 = char.RightUpperArm
armWeld.Parent = char

local armPointConnection
local tool = script:FindFirstAncestorWhichIsA("Tool")

tool.Equipped:Connect(function()
	mouse.Icon = "rbxassetid://316279304"

	armPointConnection = RunService.Heartbeat:Connect(function()
		local cframe = CFrame.new(char.UpperTorso.Position, mouse.Hit.Position) * CFrame.Angles(math.pi/2, 0, 0)
		armWeld.C0 = armOffset * char.UpperTorso.CFrame:toObjectSpace(cframe)
	end)
end)

tool.Unequipped:Connect(function()
	mouse.Icon = ""
if armPointConnection then
armPointConnection:Disconnect()
end
end)

" 12:11:30.683 UpperTorso is not a valid member of Model “Workspace.GamingExpert0312” - Client - ClientMain:8"

this is the error i get repeatedly

the character is r15, not r6 btw

#8

This means the characters upper torso model hasn’t loaded into the game yet, use a :WaitForChild(“UpperTorso”) to wait for it to load into the game.

#9

ah makes sense, why didnt i think of that. ill let you know if it works

#10

it is just saying infinite yield on all :waitforchild() statements

#11

write wait(1) on line 1. so the player will load the first second and then the script will start running
