GuiObject

Inherits from: GuiBase2d → GuiBase → Instance → Object

GuiObject is an abstract class (much like BasePart) for a 2D user interface object. It defines all the properties relating to the display of a graphical user interface (GUI) object such as Size and Position. It also has some useful read‑only properties like AbsolutePosition, AbsoluteSize, and AbsoluteRotation.

To manipulate the layout of GUI objects in special ways, you can use a layout structure such as list/flex or grid, and you can style them beyond their core properties through appearance modifiers.

Although it's possible to detect mouse button events on any GUI object using InputBegan and InputEnded, only ImageButton and TextButton have convenient dedicated events such as Activated to detect click/press.

GuiObject.ClipsDescendants

This property determines if the GuiObject will clip (make invisible) any portion of descendant GUI elements that would otherwise render outside the bounds of the rectangle.

Rotation Behavior

When StarterGui.ClipsDescendantsSupportsRotation is enabled, clipping works correctly for rotated shapes. However, clipping by rotated shapes (when the clipping parent itself is rotated) or by rounded corners (UICorner) is not supported.

When StarterGui.ClipsDescendantsSupportsRotation is not enabled and this GuiObject or any ancestor GuiObject has a non‑zero Rotation, this property is ignored and descendant GUI elements will render regardless of this property's value.

GuiObject.InputSink

Controls whether, and to what degree, the GuiObject sinks input that occurs over it, using InputSink. Sinking input prevents it from passing through to objects behind the element, including 3D objects in the world such as those with a ClickDetector or DragDetector. It defaults to InputSink.None, except on GuiButton objects (ImageButton and TextButton), where it defaults to InputSink.Activate.

This property is a more granular successor to the boolean Active property, which can only sink all input or none. The InputBegan, InputChanged, and InputEnded events fire regardless of this property's value.

GuiObject.LayoutOrder

This property controls the sorting order of the GuiObject when using a UIGridStyleLayout (such as UIListLayout or UIPageLayout) with SortOrder set to SortOrder.LayoutOrder. It has no functionality if the object does not have a sibling UI layout structure.

GuiObjects are sorted in ascending order where lower values take priority over higher values. Objects with equal values fall back to the order they were added in.

If you are unsure if you'll need to add an element between two existing elements in the future, it's a good practice to use multiples of 100 (0, 100, 200, etc.). This ensures a large gap of layout order values which you can use for elements ordered in-between other elements.

See also ZIndex which determines the object's rendering order instead of sorting order.

GuiObject.NextSelectionDown

This property sets the GuiObject selected when the user moves the gamepad selector downward. If this property is empty, moving the gamepad downward will not change the selected GUI.

Moving the gamepad selector downward sets the GuiService.SelectedObject to this object unless the GUI is not Selectable. Note that this property can be set to a GUI element even if it is not Selectable, so you should ensure that the value of a GUI's selectable property matches your expected behavior.

GuiObject.Position

This property determines the GuiObject pixel and scalar position using a UDim2. Position is centered around the object's GuiObject.AnchorPoint.

The scalar position is relative to the size of the parent GUI element, if any.

The pixel portions of the UDim2 value are the same regardless of the parent GUI's size. The values represent the position of the object in pixels. An object's actual pixel position can be read from the GuiBase2d.AbsolutePosition property.

GuiObject.Selectable

This property determines whether the GuiObject can be selected when navigating GUIs using a gamepad.

If this property is true, a GUI can be selected. Selecting a GUI also sets the GuiService.SelectedObject property to that object.

When this is false, the GUI cannot be selected. However, setting this to false when a GUI is selected will not deselect it nor change the value of the GuiService.SelectedObject property.

Add GuiObject.SelectionGained and GuiObject.SelectionLost will not fire for the element. To deselect a GuiObject, you must change the GuiService.SelectedObject property.

This property is useful if a GUI is connected to several GUIs via properties such as this GuiObject.NextSelectionUp, GuiObject.NextSelectionDown, NextSelectionRight, or NextSelectionLeft. Rather than change all of the properties so that the Gamepad cannot select the GUI, you can disable its Selectable property to temporarily prevent it from being selected. Then, when you want the gamepad selector to be able to select the GUI, simply re-enable its selectable property.

GuiObject.SelectionImageObject

This property overrides the default selection adornment used for gamepads.

Note that the chosen SelectionImageObject overlays the selected GuiObject with the Size of the image. For best results, you should size the custom SelectionImageObject via the scale UDim2 values to help ensure that the object scales properly over the selected element.

Changing the SelectionImageObject for a GuiObject element only affects that element. To affect all of a user's GUI elements, set the PlayerGui.SelectionImageObject property.

To determine or set which GUI element is selected by the user, you can use the GuiService.SelectedObject property. The player uses the gamepad to select different GUI elements, invoking the NextSelectionUp, NextSelectionDown, NextSelectionLeft, and NextSelectionRight events.

GuiObject.Size

This property determines the GuiObject scalar and pixel size using a UDim2.

The scalar size is relative to the size of the parent GUI element, if any.

The pixel portions of the UDim2 value are the same regardless of the parent GUI's size. The values represent the size of the object in pixels. An object's actual pixel size can be read from the GuiBase2d.AbsoluteSize property.

If the GuiObject has a parent, its size along each axis is also influenced by the parent's SizeConstraint.

GuiObject.Visible

This property whether the GuiObject and its descendants will be rendered.

The rendering of individual components of a GuiObject can be controlled individually through transparency properties such as GuiObject.BackgroundTransparency, TextLabel.TextTransparency and ImageLabel.ImageTransparency.

When this property is false, the GuiObject will be ignored by layout structures such as UIListLayout, UIGridLayout, and UITableLayout. In other words, the space that the element would otherwise occupy in the layout is used by other elements instead.

This property determines the order in which a GuiObject renders relative to others.

By default, GuiObjects render in ascending priority order where those with lower ZIndex values are rendered under those with higher values. You can change the render order within a ScreenGui, SurfaceGui, or BillboardGui by changing the value of its ZIndexBehavior.

If you are unsure if you'll need to add an element between two existing elements in the future, it's a good practice to use multiples of 100 (0, 100, 200, etc.). This ensures a large gap of render order values which you can use for elements layered in-between other elements.

GuiObject.MouseEnter

The MouseEnter event fires when a user moves their mouse into a GuiObject element.

Please do not rely on the x and y arguments passed by this event as a fool-proof way to determine where the user's mouse is when it enters a GUI. These coordinates may vary even when the mouse enters the GUI via the same edge - particularly when the mouse enters the element quickly. This is due to the fact the coordinates indicate the position of the mouse when the event fires rather than the exact moment the mouse enters the GUI.

This event fires even when the GUI element renders beneath another element.

If you would like to track when a user's mouse leaves a GUI element, you can use the GuiObject.MouseLeave event.

Parameters

NameTypeDefaultDescription
xintThe mouse's X screen coordinate in pixels, relative to the top left corner of the screen.
yintThe mouse's Y screen coordinate in pixels, relative to the top left corner of the screen.

GuiObject.MouseLeave

The MouseLeave event fires when a user moves their mouse out of a GuiObject element.

Please do not rely on the x and y arguments passed by this event as a fool-proof way to determine where the user's mouse is when it leaves a GUI. These coordinates may vary even when the mouse leaves the GUI via the same edge - particularly when the mouse leaves the element quickly. This is due to the fact the coordinates indicate the position of the mouse when the event fires rather than the exact moment the mouse leaves the GUI.

This event fires even when the GUI element renders beneath another element.

GuiObject.MouseMoved

Fires whenever a user moves their mouse while it is inside a GuiObject element. It is similar to Mouse.Move, which fires regardless whether the user's mouse is over a GUI element.

Note, this event fires when the mouse's position is updated, therefore it will fire repeatedly while being moved.

The x and y arguments indicate the updated screen coordinates of the user's mouse in pixels. These can be useful to determine the mouse's location on the GUI, screen, and delta since the mouse's previous position if it is being tracked in a global variable.

The code below demonstrates how to determine the Vector2 offset of the user's mouse relative to a GUI element. AbsolutePosition is measured inside the screen's GUI inset, while the x and y arguments of this event are screen coordinates that include it, so the sample calls GetGuiInset() to reconcile the two spaces instead of assuming a fixed inset size.

local Players = game:GetService("Players")
local GuiService = game:GetService("GuiService")

local CustomScrollingFrame = script.Parent
local SubFrame = CustomScrollingFrame:FindFirstChild("SubFrame")

local mouse = Players.LocalPlayer:GetMouse()

local function getPosition(X, Y)
	local topLeftInset = GuiService:GetGuiInset()

	local gui_X = CustomScrollingFrame.AbsolutePosition.X
	local gui_Y = CustomScrollingFrame.AbsolutePosition.Y

	local pos = Vector2.new(math.abs(X - gui_X), math.abs(Y - gui_Y - topLeftInset.Y))
	print(pos)
end

CustomScrollingFrame.MouseMoved:Connect(getPosition)

Note that this event may not fire exactly when the user's mouse enters or exits a GUI element. Therefore, the x and y arguments may not match up perfectly to the coordinates of the GUI's edges.

GuiObject.MouseWheelBackward

The WheelBackward event fires when a user scrolls their mouse wheel back when the mouse is over a GuiObject element. It is similar to Mouse.WheelBackward, which fires regardless whether the user's mouse is over a GUI element.

This event fires merely as an indicator of the wheel's backward movement. This means that the x and y mouse coordinate arguments don't change as a result of this event. These coordinates only change when the mouse moves, which can be tracked by the GuiObject.MouseMoved event.

Parameters

NameTypeDefaultDescription
xintThe mouse's X screen coordinate in pixels, relative to the top left corner of the screen.
yintThe mouse's Y screen coordinate in pixels, relative to the top left corner of the screen.

GuiObject.MouseWheelForward

The WheelForward event fires when a user scrolls their mouse wheel forward when the mouse is over a GuiObject element. It is similar to Mouse.WheelForward, which fires regardless whether the user's mouse is over a GUI element.

This event fires merely as an indicator of the wheel's forward movement. This means that the X and Y mouse coordinate arguments do not change as a result of this event. These coordinates only change when the mouse moves, which can be tracked by the GuiObject.MouseMoved event.

GuiObject.TouchLongPress

This event fires after a brief moment when the player holds their finger on the UI element using a touch-enabled device. It fires with a table of Vector2 that describe the relative screen positions of the fingers involved in the gesture. In addition, it fires multiple times: UserInputState.Begin after a brief delay, UserInputState.Change if the player moves their finger during the gesture, and finally UserInputState.End. The delay is platform dependent; in Studio it is a little longer than one second.

Parameters

NameTypeDefaultDescription
touchPositionsArrayAn array of Vector2 that describe the relative positions of the fingers involved in the gesture.
stateUserInputStateA UserInputState that describes the state of the gesture: - Begin fires once at the beginning of the gesture (after the brief delay) - Change fires if the player moves their finger while pressing down - End fires once at the end of the gesture when they release their finger.
