GuiService

Show Deprecated
Not Creatable
Service
Not Replicated

The GuiService is a service which currently allows developers to control what GuiObject is currently being selected by the gamepad navigator. It also allows clients to check if Roblox's main menu is currently open.

This service has a lot of hidden members, which are mainly used internally by Roblox's CoreScripts.

Summary

Properties

If activating the Select button on a Gamepad or Backslash will automatically set a GUI as the selected object.

Toggles whether or not objects in the CoreGui can be navigated using a Gamepad.

HIDDEN
NOT REPLICATED

Used to enable and disable the default controller GUI navigation.

Returns true if any menu of CoreGui is open.

READ ONLY
NOT REPLICATED

Sets the GuiObject currently being focused on by the GUI Navigator (used for Gamepads).

Used to enable and disable touch controls and touch control display UI. Defaults to true.

Methods

AddCenterDialog(dialog: Instance, centerDialogType: CenterDialogType, showFunction: function, hideFunction: function): void  


AddKey(key: string): void  


AddSelectionParent(selectionName: string, selectionParent: Instance): void  

Creates a gui selection group where gamepad gui navigation will only consider selectable gui objects that are within the group (children of selectionParent).

AddSelectionTuple(selectionName: string, selections: Tuple): void  

AddSelectionTuple works similarly to GuiService:AddSelectionParent(), but you can give it a tuple of GuiObject that you want to be contained in the group.

Beware that the second argument is not a table, but rather the first of several GuiObject in the tuple. To pass the contents of a table, use unpack/table.unpack:


local frame = script.Parent
-- Passing various GuiObject individually
GuiService:AddSelectionTuple("InventoryButtons", frame.Sort, frame.Trash, frame.Drop)
-- Unpacking a table of GuiObject (unpack/table.unpack are equivalent)
local inventoryButtons = { frame.Sort, frame.Trash, frame.Drop }
GuiService:AddSelectionTuple("InventoryButtons", unpack(inventoryButtons))
AddSpecialKey(key: SpecialKey): void  


BroadcastNotification(data: string, notificationType: number): void  


ClearError(): void  


CloseInspectMenu(): void  

Closes the Inspect Menu, if open.

ForceTenFootInterface(isForced: boolean): void  



Checks if the player Emotes menu is open.


Returns whether or not the gameplay paused notification has been disabled by the developer.

Returns whether the Inspect and Buy menu functionality is enabled.

InspectPlayerFromHumanoidDescription(humanoidDescription: Instance, name: string): void  

Allows a developer to bring up the Inspect menu showing the assets listed in this HumanoidDescription object.

InspectPlayerFromUserId(userId: number): void

Returns true if the client is using the ten foot interface, which is a special version of Roblox's UI, exclusive to consoles. This is the only guaranteed way to verify if the user is on a console or not.

RemoveCenterDialog(dialog: Instance): void  


RemoveKey(key: string): void  


RemoveSelectionGroup(selectionName: string): void

Events

Properties

AutoSelectGuiEnabled

If activating the Select button on a Gamepad or Backslash will automatically set a GUI as the selected object. Turning this off will mean that Gui navigation will still work if GuiService.GuiNavigationEnabled is enabled but you will have to set GuiService.SelectedObject manually to start Gui navigation.

CoreGuiNavigationEnabled

Hidden
Not Replicated

Toggles whether or not objects in the CoreGui can be navigated using a Gamepad.

GuiNavigationEnabled

Used to enable and disable the default controller GUI navigation.

Read Only
Not Replicated

Returns true if any menu of CoreGui is open.

SelectedObject

Sets the GuiObject currently being focused on by the GUI Navigator (used for Gamepads). This may reset to nil if the object is off-screen.

This property is changed by the GuiObject.SelectionGained and GuiObject.SelectionLost events.

If you would like to determine when this property changes without tracking the SelectionGained and SelectionLost events for all GUI elements, you can use the Changed event.

Code Samples

Printing When Gamepad Selection Changes

local GuiService = game:GetService("GuiService")
local function printChanged(value)
if value == "SelectedObject" then
print("The SelectedObject changed!")
end
end
GuiService.Changed:Connect(printChanged)

TouchControlsEnabled

Used to enable and disable touch controls and touch control display UI. Defaults to true.

You should pass a name as well to represent the name of the player that will be inspected.
