ClearAllChildren is not valid member of RBXScriptSignal?

So im not the best scripter but i tried rewriting this 2 times still same error

I started working on game on roblox and i needed this script to work for me to go forward in project.

Got stuck on this script which is called Activated, it tool script for it to fire event when tool is activated, please note the script is not finished that why there are blank functions

Here is script:

local replicatedStorage = game:GetService("ReplicatedStorage") 

local Shared = replicatedStorage:WaitForChild("Shared")|
local Remotes = Shared:WaitForChild("Remotes") 
local sword = script.Parent 

local function activated() 
	Remotes.On_Tool_Activation:FireServer() |
end 

local function equipped() 
	print("Function_Equipped:Function not finished") 
end

local function unequipped()
	print("Function_Unquipped:Function not finished")
end

sword.Equipped:Connect(equipped)
sword.Unequipped:Connect(unequipped)
sword.Activated:ClearAllChildren(activated)

Game output bellow

 02:45:35.195  ClearAllChildren is not a valid member of RBXScriptSignal  -  Client - Activated:20
  02:45:35.196  Stack Begin  -  Studio

  02:45:35.196  Stack End  -  Studio

• UPDATED -

This is from a tutorial on youtube becuse im training for making games solo I dont know much about script but here explaination

So there are 2 values in the sword and this localscript which makes error Localscript is called activated and it connected to modulescript called RemoteController. When user holds sword in hand and clicks it localscript will activate function and event here is other script

local Players = game:GetService("Players")
local replicatedStorage = game:GetService("ReplicatedStorage")
local Shared = replicatedStorage:WaitForChild("Shared")
local Remotes = Shared:WaitForChild("Remotes")
local remoteController = {}

local cooldownTable = {}

function remoteController.OnToolActivation(player)
	local currency = "Strenght"
	local character = player.Character or nil
	if character ~= nil then
		local tool = character:FindFirstChildOfClass("Tool") or nil
			if tool ~= nil then
			local amount = tool.Amount.Value
			local cooldown = tool.Cooldown.Value
			
			if not cooldownTable[player.Name] then
				cooldownTable[player.Name] = true
				player.leaderstats[currency].Value += amount
				wait(cooldown)
				cooldownTable[player.Name] = false
			end
		end
	end
end

Remotes.On_Tool_Activation.OnServerEvent:Connect(remoteController.OnToolActivation)

Players.PlayerRemoving:Connect(function(player)
	if cooldownTable[player.Name] then
		cooldownTable[player.Name] = nil
	end
end)

return remoteController

And this script will add values from tool to player. This specific tool has strenght amount of 2 so it should be supposed to add player leaderstats 2 strenght. If you can help me tnx.

Problem

:ClearAllChildren() will clear the children of an instance. If :ClearAllChildren() wasn't a thing, then it would be possibly done like this.

for i, v in ipairs(workspace.Model:GetChildren()) do
   v:Destroy()
end

But that's 3 lines of code, so :ClearAllChildren() is more convenient.

Clearing the children will clear the descendants too.

So, the actual problem is that :ClearAllChildren() only works on instances, but doesn't work on events. I can't help you with the script because I'm not sure what you're trying to do.

You can explain to me what you're trying to do down in the comments and I'll re-edit this answer.

Problem

You are trying to use the :ClearAllChildren() method on an RbxScriptSignal.

Solution

:ClearAllChildren() is a method of Instances. RbxScriptSignal is not an Instance.

RbxScriptSignals have 2 methods:

RBXScriptConnection RbxScriptSignal:Connect ( function func )

• Establishes a function to be called whenever the event is raised.
• Returns a RBXScriptConnection object associated with the connection.

and

void RBXScriptConnection:Disconnect ( )

• Yields the current thread until this signal is fired. Returns what was fired to the signal.

As you can see, :ClearAllChildren() is not one of them.

Based on the syntax of "sword.Activated:ClearAllChildren(activated)", it appears you meant to use the :Connect() method instead of :ClearAllChildren().

Code

local replicatedStorage = game:GetService("ReplicatedStorage") 

local Shared = replicatedStorage:WaitForChild("Shared")
local Remotes = Shared:WaitForChild("Remotes") 
local sword = script.Parent 

local function activated() 
    Remotes.On_Tool_Activation:FireServer() 
end 

local function equipped() 
    print("Function_Equipped:Function not finished") 
end

local function unequipped()
    print("Function_Unquipped:Function not finished")
end

sword.Equipped:Connect(equipped)
sword.Unequipped:Connect(unequipped)
sword.Activated:Connect(activated)
