Is there a better way to recieve a player's return values?

To put it simply, I made a script that gives a player (client2) an invite to a duel fight (ScreenGui) from another player (client). I am using a RemoteEvent to get client2's answer to the invitation (it will be a true/false value, true = yes and false = no). (the original script is 44 lines long, but it has a lot of unnecessary info for my question, so here is a script that simulates what Im saying better and shorter)

local client = *player sending the invite*
local client2 = *player receiving the invite*

*the invite gui*.Parent = client2.PlayerGui

*RemoteEvent*.OnServerEvent:Connect(function(plr, answer) -- "answer" is a BoolValue to the invite (true = player accepts fight request, false = player declines fight request)
	if client2 == plr then
		if answer == true then
			*bunch of stuff that makes a fight between the players happen*
		end
	end
end)

I really don't like using this method to get the player's answer to the invite. I'm currently trying to find a way to make it where a ModuleScript can be used to get the player's answers.

Please help me with this. Thank you.
