Card that can clone into player's backpack if unowned (Intermediate)?
This is my code:
--//Service
local ReplicatedStorage = game:GetService('ReplicatedStorage')
local Players = game:GetService('Players')
--//Variables
local Player = Players.LocalPlayer
local Keycards = ReplicatedStorage.Keycards:GetChildren()
--//MainScript
script.Parent.MouseButton1Down:Connect(function()
if Player.Backpack:FindFirstChild('Keycard') == nil then
if Player.Character:FindFirstChild('Keycard') == nil then
local GetKeycard = Keycards[math.random(1, #Keycards)]
GetKeycard.Parent = Player.Backpack
end
end
end)
The problem with this code is that another person who clicks the GUI will get the card even if it is owned. I would only like the card available to one person in the whole server, basically just one different card per person.
Any help please?

Try using a for loop to go through all players to see if they have the card. Hopefully this is what you were looking for. To better understand how these work here's the wiki article on them.
script.Parent.MouseButton1Click:connect(function()
local availableCard == true
for i,v in pairs(Players:GetChildren()) do --"v" would represent each player
if v.BackPack:FindFirstChild('Keycard') then
availableCard == false
end
end
if availableCard == true then
local GetKeycard = Keycards[math.random(1, #Keycards)]
GetKeycard.Parent = Player.Backpack
else
print("No card for you! >:O")
end
end)
