Is there a way to get a number of players with a value in their backpacks?

So basically I am trying to get the number of players with a value in their backpacks called Racing set to true. I know its easy, but the problem is, I'm making a racing game in which the race is supposed to end when everyone finishes, and I do that using a script that sets a value in workspace called PlayersRacing to the amount of racing players that are in the game. The problem is, I can't change the value when someone leaves during the race. (I tried PlayerRemoving, but that doesn't work) So I thought I could make a loop script that makes the PlayersRacing value the current number of players racing that are in the game, but I don't know how.

I don't think the backpack would be a proper place for a BoolValue object. Why not store it in the player instance itself? User#24403 69 — 6y

In first place, setting a value within their backpacks isn't a good idea. If it's a simple game, you can simply put the value in the player. Insert the BoolValue in StarterPlayer and it will be copied to every player instance when it is created.

You can make a while loop to check something like

function CheckRacers()
local PlayersRacing = workspace.PlayersRacing
PlayersRacing.Value = 0
  for i,v in pairs (game.Players:GetPlayers()) do
    if v.Racing.Value then
    PlayersRacing.Value = PlayersRacing.Value + 1
    end
  if PlayersRacing.Value == 0 then RaceFinished() end --Basically, if nobody had Racing value true, that means that the function should trigger the race end.
  end
end

EDIT:

function RaceFinished()
--Do whatever has to be done once the race finishes.
end

function CheckRacers()
local PlayersRacing = workspace.PlayersRacing
PlayersRacing.Value = 0
  for i,v in pairs (game.Players:GetPlayers()) do
    if v.Racing.Value then
    PlayersRacing.Value = PlayersRacing.Value + 1
    end
  end
  if PlayersRacing.Value == 0 then RaceFinished() end --Basically, if nobody had Racing value true, that means that the function should trigger the race end.
end

Use GetPlayers instead of GetChildren. User#24403 69 — 6y

That works too. dionant 23 — 6y

use :GetPlayers() with :GetChildren() you can get another object insted of player. yHasteeD 1819 — 6y

I doubt he's placing anything else in players, but yes, :GetPlayers() is the cleaner way. I'll use it myself too, thanks. dionant 23 — 6y

I know I could get it that way, but how do I actually set the value to the number of racers? 1GlF 42 — 6y

Check the edited part. It isn't the best way to do it, but I guess that's the best I can do with what I know about your game and the idea I gave you in first place. It's not the smoothest way but it should work just fine. You can make an invisible block at the end of the track that changes the player's Racing value and triggers CheckRacers() dionant 23 — 6y
