Lua Script for Displaying "Owner" Role in Roblox

This document outlines a Lua script designed for Roblox that will display the role "Owner" above a player's head and in the player tab. The script will include necessary imports, detailed documentation blocks, input validation, and commentary to ensure clarity and adherence to best practices.

Necessary Imports

In Roblox, you typically work with Instance manipulation, user interface controls, and player properties directly through the Roblox API. This script assumes you're working in a LocalScript context to update player roles effectively.

Code Implementation

--[[ 
    Function to display a role "Owner" above the player’s head and in the player tab.
    
    Parameters: 
        player: The Player object representing the player to whom the role will be assigned.
    
    Returns:
        None
    
    Exceptions:
        Raises an error if the player parameter is not valid (i.e., not a Player object).
]]

local function assignOwnerRole(player)
    -- Input Validation
    if not player or not player:IsA("Player") then
        error("Invalid player parameter. Must be a Player object.")
    end
    
    -- Create a Billboard GUI to show the role above the player's head
    local head = player.Character and player.Character:FindFirstChild("Head")
    if not head then
        error("Player's character or head not found.")
    end

    local billboardGui = Instance.new("BillboardGui")
    billboardGui.Adornee = head
    billboardGui.Size = UDim2.new(0, 200, 0, 50)
    billboardGui.StudsOffset = Vector3.new(0, 2, 0)

    local roleLabel = Instance.new("TextLabel")
    roleLabel.Text = "Owner"
    roleLabel.Size = UDim2.new(1, 0, 1, 0)
    roleLabel.BackgroundTransparency = 1
    roleLabel.TextColor3 = Color3.new(1, 0, 0) -- Red color
    roleLabel.Font = Enum.Font.SourceSansBold
    roleLabel.TextSize = 24
    roleLabel.Parent = billboardGui

    billboardGui.Parent = head

    -- Optionally, add the role in the player tab
    player:SetAttribute("Role", "Owner")  -- Setting a custom attribute
end

-- Example Usage
local Players = game:GetService("Players")
local player = Players.LocalPlayer  -- Get the local player

-- Assign the role upon player joining
assignOwnerRole(player)

Code Explanation

1. Function Definition: The function assignOwnerRole(player) is defined to assign the "Owner" role to the specified player.
2. Input Validation: The function checks if the player parameter is a valid Player object. If not, it raises an error.
3. Billboard GUI Creation:
   • Retrieves the player's head.
   • Creates a BillboardGui and a TextLabel to display "Owner" above the player's head.
   • The label is configured with size, color, and font style.
4. Setting Player Attribute: The function sets a custom attribute "Role" for displaying in the player tab.
5. Usage Example: The example demonstrates retrieving the local player and calling the assignOwnerRole function to set their role to "Owner" when the player joins.

Conclusion

This script provides a clear and efficient way to display the role "Owner" above a player's head and in the player tab when implemented in a Roblox game. It follows best practices for coding in Lua, ensuring clarity and maintainability.
