How do I make sure to identify the exact same RBXScriptConnection?

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I am currently working on a system and I need to keep track of multiple RBXScriptConnection (aka events) related to the player’s current character

function MovementService:AddPlayer(userId:number)
	local listener:userData = self.movementListeners[userId]
	if not listener then
		local character = Players:GetPlayerByUserId(userId).Character or Players:GetPlayerByUserId(userId).CharacterAdded:Wait()
		listener = {Character = character, Connections = {}}
		self.movementListeners[userId] = listener
	end
end

2. What is the issue? Include screenshots / videos if possible!
   I store a RBXScriptConnection instance in a table. However, when the player dies, I update the table to “link” the new character instead. But, since it’s a new character, I have to update the connection. That means I have to severe it and create a new one.

function MovementService:UpdateCharacter(userId:number)
	local listener:userData? = self.movementListeners[userId]
	if not listener or not listener.Connections then return end
	
	local newCharacter = Players:GetPlayerByUserId(userId).Character or Players:GetPlayerByUserId(userId).CharacterAdded:Wait()
	local existingConnections = self.movementListeners[userId].Connections
	listener = {Character = newCharacter, Connections = existingConnections} --trouble line. ExistingConnections is ofc wrong, just put it here to showcase the trouuble
	
	self.movementListeners[userId] = listener
end

But now the issue: as said, I have to severe the existing connections and make new ones, but since connections do not have any name, I can’t know which one is what and create a new one. Is there a way to identify a connection or to find a connection’s “name” even tho it doesn’t have one?

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?

Looking online for months now, but I have been asking myself this question for years. And it has finally come to a point where I can’t dodge this issue. I am completely lost

Make connections a dictionary where the key is the name of the connection and the value is the connection.

[Eternalove_fan32 (FrostDracony)]

I thought of that, and wanted to ask here if there wasn’t a more efficient method than creating a 2nd dictionary by any chance? I am trying to lean more into optimization and as a result I am trying to explore new methods (if there exist other methods, by any chance)

[bytesleuth]

You can just have one dictionary by making Connections a dictionary.

Edit: and it’s insanely efficient.

[Eternalove_fan32 (FrostDracony)]

Yeah I got that.

My bad I forgot to precise why I’ve asked this question (I edited my original message, but here again:

You can store the connections in a dictionary, where the key is the name you give it.

Or you could store them in an array, but you’d have to keep track of which index stores which connection.

Thanks for your reply! I haven’t thought about using arrays, but yeah in my scenario it would be a headache since I’ll have a lot of them. Also, since a 2nd developer is also suggesting to use dictionaries,that reassures me

I’ll mark @bytesleuth’s answer as the correct one (because they were first), but hopefully both of you will not have helped me today, but also other people in the future
