Tool keeps randomly dissapearing?

[calvin_coco (where)]

I’m trying to make “inverse kinematics” but for R6, but for some reason the tool keeps randomly dissapearing whenever I equip it.

By randomly dissapearing, I mean that it just deletes itself from the inventory. I feel like it might have to do something with this block of code but I’m not sure:

		if rightArm:FindFirstChild('RightGrip') then
			rightArm.RightGrip.Part0 = torso
			rightArm.RightGrip.C0 = CFrame.new(1.5, 0, -2)
		end

Code

-- StarterPlayer/StarterPlayerScripts/LocalScript

local Storage = game:GetService('ReplicatedStorage')
local RunService = game:GetService('RunService')

local player = game.Players.LocalPlayer

local IKModule = require(Storage.R6IK)

player.CharacterAdded:Connect(function(character)
	local t:{ BasePart } = {
		character:WaitForChild('Left Arm'), character:WaitForChild('Right Arm'),
		character:WaitForChild('Left Leg'), character:WaitForChild('Right Leg')
	}
	
	for i, v in t do
		v:GetPropertyChangedSignal('LocalTransparencyModifier'):Connect(function()
			v.LocalTransparencyModifier = 0
		end)
	end
end)

RunService.Stepped:Connect(function()
	local character = player.Character
	local torso = character and character:FindFirstChild('Torso')
	local rightArm = character and character:FindFirstChild('Right Arm')
	
	if character and torso and rightArm then
		local tool = character:FindFirstChildWhichIsA('Tool')
		
		if rightArm:FindFirstChild('RightGrip') then
			rightArm.RightGrip.Part0 = torso
			rightArm.RightGrip.C0 = CFrame.new(1.5, 0, -2)
		end

		local leftShoulder:Motor6D = torso:FindFirstChild('Left Shoulder')
		local rightShoulder:Motor6D = torso:FindFirstChild('Right Shoulder')
		if not leftShoulder or not rightShoulder then return end

		IKModule.setOriginalC0(leftShoulder)
		IKModule.setOriginalC0(rightShoulder)
		
		if not tool or not tool:FindFirstChild('LeftHandle') or not tool:FindFirstChild('RightHandle') then
			IKModule.ResetIK(leftShoulder)
			IKModule.ResetIK(rightShoulder)
			
			return
		end
		
		IKModule.UpdateIK(leftShoulder, Vector3.new(0, 0.5, 0), tool.LeftHandle.Position, 0.3, 0.5)
		IKModule.UpdateIK(rightShoulder, Vector3.new(0, 0.5, 0), tool.RightHandle.Position, 0.3, 0.5)
	end
end)


-- ReplicatedStorage/R6IK

local module = {  }

function module.setOriginalC0(motor:Motor6D)
	if motor:GetAttribute('originalC0') == nil then motor:SetAttribute('originalC0', motor.C0) end
end

function module.UpdateIK(motor:Motor6D, offset:Vector3, goal:Vector3, weight:number, smoothing:number)
	local angleOffset = CFrame.fromOrientation(math.pi / 2, 0, 0)

	local worldSpace = motor.Part0.CFrame:ToWorldSpace(CFrame.new(offset) * motor:GetAttribute('originalC0'))
	local lookAt = CFrame.lookAt(worldSpace.Position:Lerp(goal, math.clamp(weight, 0, 1)), goal) * angleOffset
	local objectSpace = motor.Part0.CFrame:ToObjectSpace(lookAt)

	motor.Transform = CFrame.new(0, 0, 0)
	motor.C0 = motor.C0:Lerp(objectSpace, smoothing)
end

function module.ResetIK(motor:Motor6D)
	motor.C0 = motor:GetAttribute('originalC0')
end

return module

Here’s a video showing what’s happening:

Anyone know how to fix this? Thanks.

Don’t know what happened, it wasn’t disappearing anymore for some reason.
