Will I have to manually remove functions connected to an object when it is destroyed?

If I connect, a function to the property, e.g. Touched of an object:

MyPart.Touched:Connect(function(OtherPart)
    ...
end)

… and at some point, I destroy this object: MyPart:Destroy() …

… is this connection automatically removed by the Engine?
Or should I worry about manually removing this connection before destroying the object?

The function will not be ‘removed’, so to speak, however there will be nothing to send the Touched signal, so you won’t need to worry about it.

I see, but technically speaking, if I have 1000 objects created and then destroyed, will there be 1000 functions taking up memory or processing, somehow hurting the game’s performance?

When a part gets destroyed, all event connections to that part are also disconnected automatically

Only the one lambda function is defined.

Additionally, a destroyed instances connections are automatically disconnected.

If connections gets spammed, there will be so much lag…

If there is another event that can still fire (like stringValue.Changed) and I connected a function to it, how do I “disconnect” that, as soon as the MyPart (in this case) is destroyed?

Store the connections as a variable then call :Disconnect(), for example:

local connection: RBXScriptConnection = <StringValue>.Changed:Connect(function(): nil
	-- Blah blah
	return nil
end)

<BasePart>.Destroying:Once(function(): nil
	connection:Disconnect()
	print("Disconnected the connection.")
end)
