Unable to play animation in script + how to make remote event only fire when tool equipped?

It says that on line 9, it is unable to cast a value to the object, and i have no idea what to do about it, and also the remote event i put in immediately fires when you join the game, and i have no idea how to code it since I'm a horrible coder. Please help.

local rep = game:GetService("ReplicatedStorage")
local PunchEquipped = rep.PunchEquipped
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local Animator = Humanoid:WaitForChild("Animator")
local tool = script.Parent
local Animation = "https://web.roblox.com/library/10336312893/Fist-Animation"
local PlayAnim = Animator:LoadAnimation("Animation")
        if tool.Equipped then
	PunchEquipped.OnServerEvent(Animation)
	if Player == tool.Parent then
		print('Tool is equipped')
		Animation.AnimationPriority = Enum.AnimationPriority.Action
		Animation.AnimationID = "https://web.roblox.com/library/10336312893/Fist-Animation"
		Animation.Parent = Character
		PlayAnim:Play()
	end
end
 

Unable to cast value to Object - Client - LocalScript:9

In line 10 you’re trying to check if Tool.Equipped returns true, but it’s an event, not a boolean. You have to type Tool.Equipped:Connect(function() which will run if the tool has been equipped. I also recommend making the AnimationTrack before Tool.Equipped. And use “rbxassetid://youranimationid” instead of the link of your animation from the website. So it will be from “https://web.roblox.com/library/10336312893/Fist-Animation” to “rbxassetid://10336312893“.

And wait, before I forget, run the animation in a server script so other players can see your animation. So fire the PunchEquipped to the server instead.

--Client (Local Script inside the tool)
local rep = game:GetService("ReplicatedStorage")
local PunchEquipped = rep.PunchEquipped
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local Animator = Humanoid:WaitForChild("Animator")
local tool = script.Parent
local AnimationId = "rbxassetid://10336312893"
local Animation = Instance.new("Animation")
Animation.AnimationId = AnimationId

tool.Equipped:Connect(function()
	PunchEquipped:FireServer(Animator, Animation, "equip")
end)

tool.Unequipped:Connect(function()
	PunchEquipped:FireServer(Animator, Animation, "unequip")
end)

--Server (Normal Script inside the tool or ServerScriptService)
local rep = game:GetService("ReplicatedStorage")
local PunchEquipped = rep.PunchEquipped

PunchEquipped.OnServerEvent:Connect(function(player: Player, animator: Animator, animation: Animation, toolStatus: string)
	for _, animTrack in pairs(animator:GetPlayingAnimationTracks()) do
		if animTrack.Animation.AnimationId ~= animation.AnimationId then
			if toolStatus:lower() == "equip" then
				local PlayAnim = animator:LoadAnimation(animation)
				
				repeat task.wait() until PlayAnim.Length > 0
				
				PlayAnim:Play()
			end
		else
			if toolStatus:lower() == "unequip" then
				animTrack:Stop()
			end
		end
	end
end)

Note: This script is untested and just a possible solution. If there are any errors or mistakes, lemme know. ;)
