"you need to make all of the scripts for every UI and make it very optimized"

-- server script 
local ReplicatedStorage = game:GetService("ReplicatedStorage")

    end
end

for _, button in pairs(classButtons) do
    button.MouseButton1Click:Connect(function()
        giveTicket(button.Name)
    end)

    frame.Size = UDim2.new(0.5, 0, 0.5, 0)
    frame.Position = UDim2.new(0.25, 0, 0.25, 0)
    frame.Parent = screenGui

local classes = {"Class1", "Class2", "Class3"} -- replace with your classes
    for i, class in ipairs(classes) do
        local button = Instance.new("TextButton")
        button.Size = UDim2.new(0.3, 0, 0.1, 0)
        button.Position = UDim2.new(0.35, 0, 0.1 * i, 0)
        button.Text = class
        button.Name = class
        button.Parent = frame
    end
end)

-- Note: This script assumes that you have a model for each class ticket named after the class in a folder named 'Tickets' inside ReplicatedStorage. When a player selects a class from the Choose Class UI, they are given the corresponding ticket. If there is no ticket for the selected class, a message is printed to the console. You will need to add your own logic for eligibility checks and what happens when the ticket is used. The UI is created when a player joins the game.
