Hi,

You can use the Players service to check when a player joins the game. Once a player joins the game, you can loop through all the current players within the game and check if the player who joined the game is friends with any of those players via player:IsFriendsWith(userId).

You can then use the BadgeService service to award any players who are friends. The code below is a simple way to achieve this effect:

-- services
local players = game:GetService("Players")
local badgeService = game:GetService("BadgeService")

-- variables
local BADGE_ID = 0000000

-- functions
local function awardBadge(player: Player)
	local success, result = pcall(
		function ()
			if (badgeService:UserHasBadgeAsync(player.UserId, BADGE_ID)) then return end
			
			return badgeService:AwardBadge(player.UserId, BADGE_ID)
		end
	)
end

local function playerAdded(player: Player)
	for index, loopedPlayer in ipairs(players:GetPlayers()) do
		if (loopedPlayer:IsFriendsWith(player.UserId)) then
			awardBadge(loopedPlayer)
			awardBadge(player)
		end
	end
end

players.PlayerAdded:Connect(playerAdded)

for index, player in ipairs(players:GetPlayers()) do
	task.spawn(playerAdded, player)
end
