open gui script

Sure! Here is a response without personal words or sentences at the beginning and end of the reply:

-- This line imports the Roact library, which is a popular library for creating graphical user interfaces in Lua.
local Roact = require(game.ReplicatedStorage:WaitForChild("Roact"))

-- The next line creates a new frame component using Roact. This frame will serve as the main container for our GUI.
local MainFrame = Roact.createElement("Frame", {
    Size = UDim2.new(0, 200, 0, 100),
    Position = UDim2.new(0.5, 0, 0.5, 0),
    AnchorPoint = Vector2.new(0.5, 0.5),
    BackgroundColor3 = Color3.fromRGB(255, 255, 255),
    BorderSizePixel = 2,
})

-- This line creates a new text label component inside the MainFrame. The text label will display "Hello, Lua GUI!".
local TextLabel = Roact.createElement("TextLabel", {
    Size = UDim2.new(1, 0, 1, 0),
    Text = "Hello, Lua GUI!",
    TextColor3 = Color3.fromRGB(0, 0, 0),
    BackgroundTransparency = 1,
    TextScaled = true,
})

-- The next line appends the TextLabel as a child of the MainFrame component.
MainFrame.Children = {
    TextLabel,
}

-- Finally, this line creates and mounts the GUI to the player's screen using Roact.mount.
local handle = Roact.mount(MainFrame, game.Players.LocalPlayer.PlayerGui)
