TopBar module - Brings back the TopBar frame from ~May 2015-March 2020

Hello,

I’ve made a simple module to bring back the TopBar frame that existed from around May 2015 up until March 2020, when Roblox updated the Core UI. The module link is here, and if you don’t want to go to the Roblox library to buy it, you can just copy-paste this code:

// Brings back the old TopBar that existed up until March 2020 (source: https://devforum.roblox.com/t/new-in-game-topbar/480226).
// This does not bring back the Settings, Chat, Playerlist, Backpack, or Health GUIs. If you want those, check this out:

// DOCUMENTATION:
	// topBar:Create(instance, props)
		// Variables:
			// instance: Valid instance to create
			// props: Table
		// Description: Creates a new Instance with properties according to the props table
		// Returns: The new instance, or false on failure.
		// Example use case: topBar:Create("BoolValue", 
			Name = "Hi";
			Value = true;
			Parent = workspace;
		);
	// getTransparencyValue(newTransparency)
		// Variables:
			// newTransparency: number
		// Description: Internal function to get the transparency value to be set when topBar:UpdateTopBarTransparency() is called. I promise it isn't useless.
		// Returns: The transparency that is computed
		// Example use case: getTransparencyValue(0.5)
	// topBar:UpdateTopBarTransparency(newTransparency)
		// Variables:
			// newTransparency: number
		// Description: Updates the top bar transparency.
		// Returns: True on success, false on failure.
		// Example use case: topBar:UpdateTopBarTransparency(0.5)
	// topBar:ToggleTopBar()
		// Description: Toggles the top bar on/off.
		// Returns: True on success, false on failure.
		// Example use case: topBar:ToggleTopBar()
	// topBar:ChangeTopBarThickness(newThickness)
		// Variables:
			// optional newThickness: number
		// Description: Changes the top bar thickness. Default is 36.
		// Returns: True on success, false on failure.
		// Example use case: topBar:ChangeTopBarThickness(72)
	// topBar:StartTopBar(parent)
		// Variables:
			// parent: Instance
		// Description: Starts the top bar engine.
		// Returns: True on success, false on failure.
		// Example use case: topBar:StartTopBar(script.Parent)

return topBar

To use this module, simply require it from a LocalScript and call StartTopBar(script.Parent). If there’s any missing documentation or anything in general missing/any bugs, let me know.

Thanks,

It’s nice!

I feel like there should be some padding between the icons and the bottom of the topbar. Other than that pretty cool module!

Sadly, it’s not possible. These are in the CoreGui, which is protected and cannot normally be accessed. You can see what works for you if you change the TOPBAR_THICKNESS in TopbarConstants. The default thickness is 36.

I must be dumb, because I don’t know to how make it work!
