How to make this loop?

local score = 0

function newcharacter(deadplayer, character)
    score = score + 1
end

for _, player in pairs(game.Players:GetPlayers()) do
    player.CharacterAdded:connect(function(character)
        newcharacter(player, character)
    end)

    if player.Character and player.Character.Parent then
        newcharacter(player, player.Character)
    end
end

How can I get this to loop? I can't use a while true do loop, cause the 'newcharacter' adds +1 when called, and when I try it in a while true do loop instead of giving out +1 it gives out like +124358. I need this to loop, cause the script is disabled, and I turn the disable off when 2 players are on, but if 2 players are on and then a third joins it doesn't count that 3rd player.

Please help, is their like a debounce or something that could work?
