Are you looking to add some flair to your Roblox game? One way to do this is by creating a custom GUI (graphical user interface) with a unique background image. In this tutorial, we’ll walk you through the steps of creating a custom GUI in Roblox that includes a background image. Whether you’re new to Roblox or an experienced developer, this tutorial will provide you with the knowledge and skills you need to create a custom GUI that stands out from the crowd.

To build a custom dialog in Roblox that asks a question and has a custom background image, you can use the following steps:

1. Open Roblox Studio and create a new script in the Workspace.
2. In the script, create a new local variable question and set it to the question you want to ask the player.
3. Create a new function called ShowDialog, which will be responsible for displaying the custom dialog to the player.
4. Inside the ShowDialog function, use the Instance.new function to create a new ScreenGui object and assign it to a local variable called screenGui. This will be the container for the custom dialog.
5. Use the Instance.new function again to create a new Frame object and assign it to a local variable called frame. This will be the frame that holds the custom dialog.
6. Use the Instance.new function to create a new TextLabel object and assign it to a local variable called textLabel. This will be used to display the question to the player.
7. Set the Parent property of the frame and textLabel objects to the screenGui object, so that they are displayed within the custom dialog.
8. Set the Text property of the textLabel object to the value of the question variable. This will display the question to the player.
9. Set the BackgroundColor3 property of the frame object to the color you want to use for the background of the custom dialog.
10. Set the BackgroundTransparency property of the frame object to 0, so that the background color is visible.
11. Use the Instance.new function to create a new ImageLabel object and assign it to a local variable called imageLabel. This will be used to display the custom background image.
12. Set the Parent property of the imageLabel object to the frame object, so that it is displayed within the custom dialog.
13. Set the Image property of the imageLabel object to the file path of the custom background image you want to use.
14. Set the Size and Position properties of the imageLabel object to control how the custom background image is displayed within the custom dialog.
15. Use the Instance.new function to create new TextButton objects for each of the buttons you want to include in the custom dialog. These buttons can be used to allow the player to respond to the question.
16. Set the Parent property of each of the TextButton objects to the frame object, so that they are displayed within the custom dialog.
17. Set the Text property of each TextButton object to the label you want to display on the button.
18. Set the Position and Size properties of each TextButton object to control the layout of the buttons within the custom dialog.
19. Set the Parent property of the screenGui object to the PlayerGui object of the player, so that the custom dialog is displayed to the player.

This should create a custom dialog that asks a question and has a custom background image. You can then use the buttons in the dialog to allow the player to respond to the question.

Here is the Roblox LUA code that demonstrates how to build a custom dialog in Roblox that asks a question and has a custom background image:

local question = "What is your favorite color?"

function ShowDialog()
    -- Create the ScreenGui object that will contain the custom dialog
    local screenGui = Instance.new("ScreenGui")

    -- Create the Frame object that will hold the custom dialog
    local frame = Instance.new("Frame")
    
    -- Create the TextLabel object that will display the question
    local textLabel = Instance.new("TextLabel")

    -- Set the Parent properties of the frame and textLabel objects to
    -- the screenGui object, so they are displayed within the custom dialog
    frame.Parent = screenGui
    textLabel.Parent = frame

    -- Set the Text property of the textLabel object to the value of the 
    -- question variable
    textLabel.Text = question

    -- Set the BackgroundColor3 property of the frame object to the color 
    -- you want to use for the background of the custom dialog
    frame.BackgroundColor3 = Color3.new(1, 1, 1)

    -- Set the BackgroundTransparency property of the frame object to 0, 
    -- so the background color is visible
    frame.BackgroundTransparency = 0

    -- Create the ImageLabel object that will display the custom background image
    local imageLabel = Instance.new("ImageLabel")

    -- Set the Parent property of the imageLabel object to the frame object, so it 
    -- is displayed within the custom dialog
    imageLabel.Parent = frame

    -- Set the Image property of the imageLabel object to the file path of the 
    -- custom background image you want to use
    imageLabel.Image = "path/to/custom/background/image.png"

    -- Set the Size and Position properties of the imageLabel object to 
    -- control how the custom background image is displayed within the custom dialog
    imageLabel.Size = UDim2.new(1, 0, 1, 0)
    imageLabel.Position = UDim2.new(0, 0, 0, 0)

    -- Create the TextButton objects that will be used to allow the player to 
    -- respond to the question
    local button1 = Instance.new("TextButton")
    local button2 = Instance.new("TextButton")

    -- Set the Parent properties of the TextButton objects to the frame object, 
    -- so they are displayed within the custom dialog
    button1.Parent = frame
    button2.Parent = frame

    -- Set the Text properties of the TextButton objects to the labels you want 
    -- to display on the buttons
    button1.Text = "Red"
    button2.Text = "Blue"

    -- Set the Position and Size properties of the TextButton objects to 
    -- control the layout of the buttons within the custom dialog
    button1.Position = UDim2.new(0, 10, 0, 10)
    button1.Size = UDim2.new(0, 50, 0, 20)
    button2.Position = UDim2.new(0, 70, 0, 10)
    button2.Size = UDim2.new(0, 50, 0, 20)

    -- Set the Parent property of the screenGui object to the PlayerGui 
    -- object of the player, so the custom dialog is displayed to the player
    screenGui.Parent = game.Players.LocalPlayer:WaitForChild("PlayerGui")
end

-- Call the ShowDialog function to display the custom dialog
ShowDialog()

This code creates a custom dialog that asks the question “What is your favorite color?”, and displays two buttons labeled “Red” and “Blue”. When the player clicks one of the buttons, you can use the Button1.MouseButton1Click and Button2.MouseButton1Click events to handle the player’s response.

For example, you could use the following code to print a message to the Output window when the player clicks one of the buttons:

button1.MouseButton1Click:Connect(function()
    print("The player clicked the Red button.")
end)

button2.MouseButton1Click:Connect(function()
    print("The player clicked the Blue button.")
end)

This is just one example of how you could use a custom dialog in Roblox. You can customize the dialog further by adding additional buttons, changing the layout of the dialog, or adding other elements like checkboxes or text input fields. You can also use the button1.MouseButton1Click and button2.MouseButton1Click events to perform other actions in your game, such as changing the game state or triggering other events.
