Something unexpectedly tried to set the parent of Tool to Folder while trying to set the parent of Tool Current parent is Backpack

I’m trying to direct a tool to a folder when it enters the backpack, but it runs this error. I understand that it breaks because I’m trying to set the parent at the same time as the game, but I haven’t found an effective solution to solve it. I’ve attempted to delay placing the object in the folder, but it just ends up breaking my other scripts that require perfect timing to work.

Demo code to help:

plr.Backpack.ChildAdded:Connect(function(child)
	child.Parent = Folder
end)

If anyone can provide solutions, it’d be much appreciated.

Maybe you can use a slight delay before changing the parent of the tool It can be done using the wait() function. For example

plr.Backpack.ChildAdded:Connect(function(child)
	wait(0.1) -- wait for 0.1 seconds
	child.Parent = Folder
end)

Or you could check if the child is a tool before changing its parent:

plr.Backpack.ChildAdded:Connect(function(child)
	if child:IsA("Tool") then
		child.Parent = Folder
	end
end)

Adding a delay like @deathslaye345 said would probably be your best bet here. Use task.wait() though because wait() is deprecated iirc.

A delay as others have stated, would probably be the best option. I assume your other scripts are trying to reference the needed resources without any checks beforehand which cause them to break due to imperfect timing. In order to prevent the other scripts from breaking, you should also delay them appropriately. Maybe using Folder.ChildAdded:Wait() or an equal delay to the one used to parent the Tool.
