Notifications in a Nutshell

An in-game notification is a message that appears whenever a game wants you to pay attention to. One example of using in-game notifications is Jailbreak, whenever a player robs a store (Bank, Jewelery, Gas Station, etc.), it sends a notification to the police team. But how can I implement it into my own game?", you may ask. This tutorial shows you how to use in-game notifications in your game.

Creating the notification

Creating a notification MUST be executed within a LocalScript, or else, the console would return this error and would not work:

StarterGui:SetCore must be called from a local script

To do this, you need to create a local script, preferably in StarterPlayer > StarterPlayerScripts, and enter this code:

game.StarterGui:SetCore("SendNotification", { -- Tell StarterGui to create a notification
    Title = "Test",
    Text = "Hello world!",
    Duration = 5
})

Test this in Studio, and you should see a notification.

Creating a notification with buttons

But what if we wanted to create a notification with buttons? Well, you can implement that in your notification! Now, enter this code to create a notification that has two buttons:

game.StarterGui:SetCore("SendNotification", { -- Tell StarterGui to create another notification, but with buttons
    Title = "Message",
    Text = "Why hello there!",
    Button1 = "Hello",
    Button2 = "Goodbye",
    Duration = 5
})

Test this in Studio, and you should see a notification with two buttons.

Interacting with buttons

In the code above, whenever either button is clicked on, it currently does nothing. This is because there is no code to handle when the button is clicked on.

Now, enter in this code:

local function callback(Text)
    if Text == "Hello" then
        print("user clicked on the Hello button")
    else if Text == "Goodbye" then
        print("user clicked on the Goodbye button")
    end
    end
end

local BindableFunction = Instance.new("BindableFunction")
BindableFunction.OnInvoke = callback -- When this is invoked, fire the function "callback"

game.StarterGui:SetCore("SendNotification", { -- Tell StarterGui to create a notification
    Title = "Message",
    Text = "Why hello there!",
    Button1 = "Hello",
    Button2 = "Goodbye",
    Duration = 5,
    Callback = BindableFunction
})

Before you can test this code, make sure you can view the Output in Studio. If not, click on View, then click on Output, and you should see the output.

Now, test the game, and, depending on what button you clicked on, you should see one of these messages in the output:

user clicked on the Hello button

user clicked on the Goodbye button
