Disconnecting an event does not work?

Hello there, I have a question about what I am doing wrong. So AmouseClick() is a function that compares Mouse.Target and the humanoid's torso's distance between eachother. It says that if the distance is less than the range it would cause damage to Mouse.Target.Parent.Humanoid

My problem however is that I add debounce in a way different from yours, Instead I disconnect the event nested in the function as highlighted with a comment.

No errors, does not disconnect at all, (tried removing the reconnecting part and still doesn't disconnect) and just let's the player spam their mouse.

The debounce is running once. I'm not fully sure of how to debounce since I'm not sure if events still do listen while a wait() is yielding the script. Just think of it has people walking into a door closed, won't they still walk in once the door is open?

Note: variable mouseEvent is stated before this function and is assigned an event after this function.

local function AmouseClick()
	if Settings.Class == nil then
		return nil
	end
	print("Mouse Clicked")
	if not debounce then 
		if player.Team == game.Teams.Zombies then
			if mouse.Target.Parent:FindFirstChild("Player") then
				local targetPlayer = game.Players:GetPlayerFromCharacter(mouse.Target.Parent)
				if targetPlayer.Team == game.Teams.Survivors then
					local distance = (character.HumanoidRootPart.Position - mouse.Target.Position).Magnitude
					if distance < Settings.Range then
						local humanoid = mouse.Target.Parent.Humanoid
						humanoid:TakeDamage(Settings.Damage)
					end
				end
				
			end
		end
		debounce = true
	else
		print("Disconnecting mouse event")		--This is the problem
		mouseEvent:Disconnect()
		wait(Settings.AttackTime) 					
		mouseEvent = mouse.Button1Down:Connect(AmouseClick)
	end
end

mouse.Button1Down:Connect(AmouseClick)

Thank you for viewing this!

You have to define Mouse Event before you do anything with it. That's like reading a book backwards.

 print("Disconnecting mouse event")      --This is the problem
	mouseEvent = mouse.Button1Down:Connect(AmouseClick)
	wait(Settings.AttackTime)  
	mouseEvent:Disconnect()                 

See if this works

local function AmouseClick()
    if Settings.Class == nil then
        return nil
    end
    print("Mouse Clicked")
    if not debounce then 
        if player.Team == game.Teams.Zombies then
            if mouse.Target.Parent:FindFirstChild("Player") then
                local targetPlayer = game.Players:GetPlayerFromCharacter(mouse.Target.Parent)
                if targetPlayer.Team == game.Teams.Survivors then
                    local distance = (character.HumanoidRootPart.Position - mouse.Target.Position).Magnitude
                    if distance < Settings.Range then
                        local humanoid = mouse.Target.Parent.Humanoid
                        humanoid:TakeDamage(Settings.Damage)
                    end
                end

            end
        end
        debounce = true
    else
        print("Disconnecting mouse event")      --This is the problem
        mouseEvent:Disconnect()
        wait(Settings.AttackTime)                   
        mouseEvent = mouse.Button1Down:Connect(AmouseClick)

		debounce = false --//We have to make sure that the debounce gets reset or the function won't work the way it was intended.
    end
end

mouseEvent = mouse.Button1Down:Connect(AmouseClick)
