Adds a UnityEngine.UI.CanvasScaler that scales the canvas with the screen from a reference resolution, following the width at matchWidthOrHeight 0 and the height at 1. Does nothing and returns null without a canvas object.

Declaration

public static CanvasScaler AddReferenceResolutionScaler(GameObject canvasObject, Vector2 referenceResolution, float matchWidthOrHeight)

Parameters

Type	Name	Description
GameObject	canvasObject
Vector2	referenceResolution
float	matchWidthOrHeight

Returns

Type	Description
CanvasScaler

CalculateBoundingRect(RectTransform[])

Declaration

public static RectTransform CalculateBoundingRect(RectTransform[] rectTransforms)

Parameters

Type	Name	Description
RectTransform[]	rectTransforms

Returns

Type	Description
RectTransform

IsStretchedX(RectTransform)

Declaration

public static bool IsStretchedX(RectTransform rt)

Parameters

Type	Name	Description
RectTransform	rt

Returns

Type	Description
bool

IsStretchedY(RectTransform)

Declaration

public static bool IsStretchedY(RectTransform rt)

Parameters

Type	Name	Description
RectTransform	rt

Returns

Type	Description
bool

MeasureStackedRowExtent(RectTransform, int, float)

Measures how tall the first rowCount visible rows of a stacked container are, including the layout group's spacing and vertical padding.

Declaration

public static float MeasureStackedRowExtent(RectTransform container, int rowCount, float fallbackSpacing)

Parameters

Type	Name	Description
RectTransform	container	The container whose children are measured.
int	rowCount	How many rows to include.
float	fallbackSpacing	Spacing used when the container carries no layout group.

Returns

Type	Description
float	The measured height, or 0 when there is nothing to measure.

Remarks

Only active children count: a pooled list keeps its surplus rows alive but deactivated, and measuring those would clamp the viewport to a height the player never sees filled.

PinScrollViewportHeight(ScrollRect, float)

Pins a scroll viewport to a fixed height so its layout parent cannot stretch it back open.

Declaration

public static void PinScrollViewportHeight(ScrollRect scrollRect, float height)

Parameters

Type	Name	Description
ScrollRect	scrollRect	The viewport's ScrollRect.
float	height	The height to pin, in pixels. Ignored when not positive.

SafeSetHeight(RectTransform, float)

Declaration

public static void SafeSetHeight(RectTransform rt, float height)

Parameters

Type	Name	Description
RectTransform	rt
float	height

SafeSetWidth(RectTransform, float)

Declaration

public static void SafeSetWidth(RectTransform rt, float width)

Parameters

Type	Name	Description
RectTransform	rt
float	width

StretchToParent(RectTransform, Vector2, Vector2)

Stretches a rect over its whole parent, keeping the given insets from the bottom-left and the top-right edges. Does nothing for a null rect.

Declaration

public static void StretchToParent(RectTransform rt, Vector2 offsetMin = null, Vector2 offsetMax = null)

Parameters

Type	Name	Description
RectTransform	rt	The rect to stretch.
Vector2	offsetMin	Inset from the parent's bottom-left corner.
Vector2	offsetMax	Inset from the parent's top-right corner (negative values pull it inwards).

WaitForComponent<T>(MonoBehaviour, GameObject, Action<T>, float)

Declaration

public static IEnumerator WaitForComponent<T>(MonoBehaviour context, GameObject root, Action<T> onFound, float timeout = 2) where T : Component

Parameters

Type	Name	Description
MonoBehaviour	context
GameObject	root
Action<T>	onFound
float	timeout

Returns

Type	Description
IEnumerator

Type Parameters

Name	Description
T

WrapInVerticalScrollViewport(RectTransform, string)

Wraps a vertically stacked container in a masked, clamped UnityEngine.UI.ScrollRect viewport, so a list that outgrows its panel scrolls instead of spilling off-screen.

Declaration

public static ScrollRect WrapInVerticalScrollViewport(RectTransform content, string viewportName)

Parameters

Type	Name	Description
RectTransform	content	The container holding the rows. Must already have a parent.
string	viewportName	Name given to the created viewport object.

Returns

Type	Description
ScrollRect	The configured ScrollRect, or `null` when `content` is null or unparented.

Remarks

The container is reparented under a new viewport object that takes its place in the parent's layout, keeping the sibling order the panel authored. A UnityEngine.UI.ContentSizeFitter is added to the container when it has none, because a ScrollRect's content must size itself for the scrollable extent to be known at all.

Shared by every panel that renders a growable row list — the leaderboard's ranked entries and the achievements listing — because the viewport wiring is one piece of knowledge, and two hand-written copies drift into two different scroll behaviours.
