How to detect if a part is added to a folder?

Help and Feedback Scripting Support
#1

I am new to scripting.

GOAL:
I want to dynamically add a new part inside of the Targets folder so that all of my pets will follow it. The part will be added when the player clicks on a surface (this target part placing system is already implemented).

CODES:

I will only paste relevant codes. Here is simplified code in my script (the script is a child of the pet model).

– PET MODEL SCRIPT –

local targetsFolder = game.Workspace.Targets
targetsFolder.ChildAdded:Connect(function(child)
    print("Something is added to workspace")
end)

PROBLEM:

I cannot implement a move code because when I add a new part inside Targets folder, the pet model script does not run (print does not work). How can I make a code inside the pet model script wherein it triggers if a part is added to a folder?

You should put this in Scripting Support category. Being said so, check out ChildAdded and ChildRemoved.

Then you could check whether the instance is a Part using the :IsA() function inside an if-statement.

Hello, does ChildAdded only trigger the Instance.new(“Part”) is invoked on the same file or does it work even if Instance.new(“Part”) is invoked on other files?

function addTarget() 
	local workspace = game.Workspace
    local mouse = player:GetMouse()
    local position = mouse.Hit.p
    local target = Instance.new("Part")
    target.Size = Vector3.new(1, 1, 1)
    target.Position = position
    target.Anchored = true
    target.CanCollide = false
    target.Name = "Target"

    local value = Instance.new("StringValue")
    value.Name = "Owner"
    value.Value = player.Name
    value.Parent = target

    target.Parent = workspace.Targets
end

Here is my addTarget code from a LocalScript. But, whenever I add a target the ChildAdded in the pet model script does not trigger.

Changes made (creating a part in this case) on a client can only be observed by said client. The folder cannot see this because it is server sided, instead, pass information from the client to the server using remote events.

#6 
local targetsFolder = game.Workspace.Targets

targetsFolder.ChildAdded:Connect(function(child)
    if child:IsA("Part") then
        print("A new part has been added to the folder!")
    end    
end)
