Table.remove/insert is not always working

Help and Feedback Scripting Support

I’m working on a function where you can remove/insert a player to a table:

function module.PlayerLoser(Player)
	local PlayersPlaying = module["PlayersPlaying"]
	local PlayersNotPlaying = module["PlayersNotPlaying"]
	if table.find(PlayersPlaying, Player.Name) then
		table.remove(PlayersPlaying, Player.Name)
		table.insert(PlayersNotPlaying, Player.Name)
	end
end

However, for any reason, sometimes i get the error that the second argument must be a number, and not a string, while sometimes, this error is not showing and everything works, i’ve tried to remove/insert a value in a different way:

PlayersPlaying[Player.Name] = nil (or) true

But i feel that this way is not an accurate way to fix this, and i would like to use table.insert/remove instead of that. Thanks for reading :slight_smile:

What do you mean this is not “accurate”? To clear an entry you need to set it to nil. table.remove and table.insert are meant for removing/inserting to the array part of a table

You need the numerical index of an element to use table.remove().

Should be something like this:

function module.PlayerLoser(Player)
	local PlayersPlaying = module["PlayersPlaying"]
	local PlayersNotPlaying = module["PlayersNotPlaying"]
	if table.find(PlayersPlaying, Player.Name) then
		table.remove(PlayersPlaying, table.find(PlayersPlaying, Player.Name))
		table.insert(PlayersNotPlaying, Player.Name)
	end
end

table.remove takes the numbered index of an array and removes the item at that index. To remove the player’s name from the array, you could use a numeric for loop and remove it that way.

local Names = {"TheeDeathCaster", "Noob", "BestFriend"};

for Count = 1, #Names do
    if (Names[Count] == "Noob") then
        table.remove(Names, Count);
    end
end

print(unpack(Names)); -- TheeDeathCaster BestFriend

If you have any questions don’t be afraid to ask. I hope this helped. :slight_smile:
