invite system for 20 coins

[outer topaz]

how do i make it so when a player invites someone then they will get 20 coins (only if the invited player joins, and they can only get it once)

i already have leaderstats for the coins

whenever i join back after spending the coins it just gives them back

You can invite like this
@outer topaz

local Players = game:GetService("Players")
local SocialService = game:GetService("SocialService")

local player = Players.LocalPlayer

local Button = script.Parent

Button.Activated:Connect(function()
    pcall(function()
        if SocialService:CanSendGameInviteAsync(player) then
            SocialService:PromptGameInvite(player)
        end
    end)
end)

This is localscript inside button btw.
And you just do Player:GetJoinData() on a server code to see how they joined.
After that just do your currency stuff

@outer topaz

take a look at this

[outer topaz]

alright

if the leaderstat is called "Coins" would i just change this to coins

[hexed notch]

yeah

if findfirstchild is not working try adding a waitforchild like this:

local coin = leaderstats:WaitForChild("Coins")

[outer topaz]

wow thx

it works but how do i make it so the player can only do it once
