Class UnityScrollbarBuilder

Builds a minimal, theme-independent scrollbar (translucent track + draggable handle) entirely in code, so any scrollable view can show scroll feedback without requiring an authored prefab. The bar is anchored as an overlay along the right edge (vertical) or bottom edge (horizontal) of its parent; callers may re-anchor the returned bar to span a specific region (e.g. a menu's visible options area).

Syntax

public class UnityScrollbarBuilder

Constructors

UnityScrollbarBuilder()

Declaration

public UnityScrollbarBuilder()

Fields

DefaultThickness

Declaration

public const float DefaultThickness = 10

Field Value

Type	Description
float	Default thickness of a generated scrollbar in canvas units.

Methods

Attach(ScrollRect, Scrollbar, bool)

Wires a built scrollbar to a ScrollRect on the matching axis. Uses auto-hide visibility so the bar only appears when the content actually overflows the viewport.

Declaration

public static void Attach(ScrollRect scrollRect, Scrollbar scrollbar, bool vertical)

Parameters

Type	Name	Description
ScrollRect	scrollRect	The ScrollRect driving the scrollable content.
Scrollbar	scrollbar	A scrollbar created by Build(RectTransform, bool, float).
bool	vertical	True to wire the vertical axis; false for the horizontal axis.

Remarks

AutoHideAndExpandViewport is deliberately avoided: it requires the bar to be a ScrollRect child with stretch anchors, which the overlay layout does not guarantee.

Build(RectTransform, bool, float)

Creates a scrollbar GameObject under parent anchored as an overlay along the right edge (vertical) or bottom edge (horizontal).

Declaration

public Scrollbar Build(RectTransform parent, bool vertical, float thickness = 10)

Parameters

Type	Name	Description
RectTransform	parent	The RectTransform the scrollbar is created under.
bool	vertical	True for a vertical bar (right edge); false for a horizontal bar (bottom edge).
float	thickness	Bar thickness in canvas units.

Returns

Type	Description
Scrollbar	The configured UnityEngine.UI.Scrollbar component, ready to be wired with Attach(ScrollRect, Scrollbar, bool).
