ObjectValue Value Disappearing

Help and Feedback Scripting Support

#1

Hello,

In a ScreenGUI, I have an ObjectValue named “Down”, which has its value initialized to “down”. Also, in the ScreenGUI, I have a LocalScript which contains the following code that modifies the value:

gui = script.Parent.ClawBase
d = gui.DownFrame.D

d.InputBegan:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		script.Parent.Down.Value:FireServer(true)
	end
end)
d.InputEnded:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		script.Parent.Down.Value:FireServer(false)
	end
end)

I attempted to add another ObjectValue named “Drop”, and added the following code:

gui = script.Parent.ClawBase
d = gui.DownFrame.D
drop = gui.DropFrame.Drop -- New Line

d.InputBegan:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		script.Parent.Down.Value:FireServer(true)
	end
end)
d.InputEnded:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		script.Parent.Down.Value:FireServer(false)
	end
end)

drop.Activated:Connect(function(input) -- New Lines
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		script.Parent.Drop.Value:FireServer()
	end
end)

Unlike the other ObjectValue, I am unable to initialize the “Drop” ObjectValue Value. When I playtest the game, the Value becomes nil, even if I try to set it to something.

When I trigger the “script.Parent.Drop.Value:FireServer()” code, I get the Players.tech_voyager.PlayerGui.ElectronControl.LocalScript:50: attempt to index nil with ‘FireServer’ error. How do I fix this issue?

Thanks! :slight_smile:

I’m not sure how the string “down” relates to a RemoteEvent instance. Are you actually storing references to RemoteEvents in your ObjectValues? If so, why? If you have a RemoteEvent named “Value”, know that the dot operator will prioritize properties over children, so using .Value will attempt to read the current value of your ObjectValue, not access the child RemoteEvent

#3

The script is supposed to trigger a RemoteEvent in a separate model which is also named “Down”. There is a script in the model which is linked to the ObjectValue:

script.Parent.Down.OnServerEvent:Connect(function(player1, args)
	if MovementActive and args == true and player1.Name == player.Value then
		GY.Velocity = -1
	elseif MovementActive and args == false then
		GY.Velocity = 0
	end
end)

ObjectValues are references to Instances in the datamodel. You can’t initialize and ObjectValue.Value to the string “down”. You should probably start by naming your instances and variables in a less confusing manner, and double checking that you’re actually making valid assignments to the ObjectValues.

Also, why use ObjectValues at all? Why not just store the references in the script. Using ObjectValues for indirection breaks type-inference code completion, making it easier to introduce bugs. Like your Down.Value is a RemoteEvent, but Drop.Value should be a Tool reference, right?

Also, if the drop thing is a Tool, make sure you update the reference any time the Backpack refreshes. IIRC, it still sets up twice on join, so you’re possibly getting a reference to a Tool that gets created and then immediately destroyed with the first backpack refresh.

The Value of the ObjectValue was referencing the RemoteEvent I mentioned, which also shares the same name. By assigning the Value to that RemoteEvent, the problem gets resolved. I will probably use more intuitive names for the components going forward.

Thank you for the help! :slight_smile:
