How can I get a player name from a list ?

Asked 247 views1 answers

I have a problem, I would like to get the play name from a list and put it in a variable (string).

	local gameresults = "oneplayeralive"
	if #activecontestants == 1 then 
		partforwinner.CanCollide = true
		for _, player in pairs(activecontestants) do
			if player then
				local playername = player:GetFullName()
				event:FireAllClients(gameresults, playername)
			end
		end
	else
		gameresults = "nowinner"
	end

And to put it in a gui : 

event.OnClientEvent:connect(function(...)
	local tuple = ...
	if tuple == "oneplayeralive" then
		resultsannonce.Text = "The winner is"
		winnerannonce.Text = tuple[2]
	else
		resultsannonce.Text = "No winner"
		winnerannonce.Visible = false
	end

But, when I test, it's send me an error because "tuple[2]" is not a string.

If someone could help me, it's could be great, thanks you.

(sorry for the bad english, i'm french)

The reason your program errored was because you did not put brackets { } around the TWO arguments you had for your tuple in the FireAllClients method. While I simplified your code to not have that be necessary, it's important to recognize that FireAllClients only takes one argument, so put all your parameters in a table. The code below works the same way your old code did functionality wise; I assume that the if-statement is inside some sort of function or other callable system on your server.

You had a second problem where if there was no winner, the clients wouldn't have been informed. I made it FireAllClients regardless of the result.

Server Code

local player = nil
if #activecontestants == 1 then
	partforwinner.CanCollide = true
	player = activecontestants[1]
end
event:FireAllClients(player)

Client Code

event.OnClientEvent:connect(function(...)
	local tuple = ...
	if tuple then
		resultsannonce.Text = "The winner is"
		winnerannonce.Text = tuple.Name
	else
		resultsannonce.Text = "No winner"
		winnerannonce.Visible = false
	end
end)
