Animations do not work

[AzertyWasTaken (Azerty)]

Hi there,
I made a zipline script similar to the JToH one but the zipline animation don’t work.
I searched on online tutorials to make the animation work but I didn’t found how to fix this.
This this the zipline script. It is in a local script and its parent is the zipline part.

local TweenService = game:GetService("TweenService")
local UserInputService = game:GetService('UserInputService')

local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://3268037702"

return function()
	local parent = script.Parent
	local propelVelocity = parent.PropelVelocity.Value
	local EPC = parent.PC
	EPC.UpperLimit = parent.Lenght.Size.Z
	parent.Lenght:Destroy()
	
	local riding = false
	--decoRope.Color =  script.Parent.BrickColor--BrickColor.new("Really black")

	local R1 = Instance.new("Attachment",parent)
	R1.Position = Vector3.new(0,0,-EPC.UpperLimit)
	
	local decoRope = Instance.new("RopeConstraint",parent)
	decoRope.Length = EPC.UpperLimit-1
	decoRope.Visible = true
	decoRope.Thickness = 0.25
	decoRope.Attachment0 = parent.Start
	decoRope.Attachment1 = R1
	--DecoRope.Name = "DecoRope"
	--local val
	--if script.Parent:FindFirstChild("ButtonActivated") ~= nil then
	--	val=Instance.new('BoolValue',script.Parent)
	--	val.Name='Activated'
	--end
	script.Parent.Touched:Connect(function(part)
		local char = part.Parent
		local plr = game.Players:GetPlayerFromCharacter(char)
		local human = char:FindFirstChild("Humanoid")

	--	if part.Parent:FindFirstChild("Humanoid") and not (val and not val.Value) and plr == game.Players.LocalPlayer then
		if riding or not human then return end
		
		local hrp = char:FindFirstChild("HumanoidRootPart")

		riding = true
		
		local ropeBar = Instance.new("Part",parent)
		ropeBar.Size = Vector3.new(4,0.5,0.5)
		ropeBar.CanCollide = false
		ropeBar.CFrame = hrp.CFrame * CFrame.new(0,2.75,0)

		local ropeGuide = Instance.new("Part",parent)
		ropeGuide.Size = Vector3.new(1,1,1)
		ropeGuide.CanCollide = false
		ropeGuide.Transparency = 1
		ropeGuide.CFrame = parent.CFrame

		local P1 = Instance.new("Attachment",ropeGuide)
		local P2 = Instance.new("Attachment",ropeBar)
		
		local rope = Instance.new("RopeConstraint",ropeGuide)
		rope.Length = 8
		rope.Visible = true
		rope.Attachment0 = P1
		rope.Attachment1 = P2

		local A2 = Instance.new("Attachment",ropeGuide)
		
		local weld = Instance.new("WeldConstraint",ropeBar)
		weld.Part0 = hrp
		weld.Part1 = ropeBar
		
		local PC = EPC:Clone()
		PC.Parent = parent
		PC.Attachment1 = A2
		
		if propelVelocity ~= 0 then
			local bodyVelocity=Instance.new('BodyVelocity',ropeGuide)
			bodyVelocity.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
			bodyVelocity.Velocity = parent.CFrame.LookVector*propelVelocity
			bodyVelocity.P = 100
		end

		local bodyGyro=Instance.new('BodyGyro',ropeBar)
		bodyGyro.MaxTorque = Vector3.new(math.huge,math.huge,math.huge)
		bodyGyro.CFrame = parent.CFrame

	--			RopeBar.CustomPhysicalProperties = PhysicalProperties.new(10,0,0)
	--			RopeBar.Color = script.Parent.Color
	--			RopeGuide.Color=script.Parent.Color
	--			RopeGuide.CustomPhysicalProperties = PhysicalProperties.new(20,0,0) 

	--			Rope.Color = script.Parent.BrickColor--BrickColor.new("Really black")

	--			if PV~=0 then
	--				BV.Parent = RopeGuide
	--			end
		
		local animator = human:WaitForChild("Animator")
		local track = animator:LoadAnimation(animation)
		track:Play()
		
		local disconnect = false
		if not parent.CannotDismount.Value then
			UserInputService.JumpRequest:Connect(function()
				disconnect=true
			end)
		end
		
		repeat wait()
			human.PlatformStand = true
		until human.Health <= 0 or disconnect or PC.CurrentPosition >= PC.UpperLimit
	--			if PC then PC:Destroy() end
		weld:Destroy()
		riding = false
	--			if not autodisconnect then
	--				PC.Attachment1=nil
	--			end
	--			BG:Destroy()
		ropeBar:Destroy()
		ropeGuide:Destroy()
		track:Stop()
		track:Destroy()

		human.PlatformStand = false
		human:ChangeState'Jumping'
	end)
end

Can you help me please?

sorry for the insanely late reply over a year but i’m pretty sure it doesn’t work because you dont have permissions to use it
