Class ScyllaUIAdaptiveStack

Orientation-responsive stack that switches between horizontal and vertical layout at runtime based on the parent viewport's aspect ratio. Useful for UI surfaces that should reflow between landscape (side-by-side) and portrait (top-to-bottom) without designer intervention. Extends ScyllaUIStackBase with a dynamically computed IsHorizontal orientation.

Syntax

[AddComponentMenu("Scylla/UI/Layout/Adaptive Stack")]
public sealed class ScyllaUIAdaptiveStack : ScyllaUIStackBase, ILayoutElement

Remarks

The stack reads its parent UnityEngine.RectTransform's aspect ratio on every solve. When the parent's width / height ratio is greater than or equal to AspectThreshold, the stack lays out horizontally; otherwise vertically. The default threshold of 1.0 corresponds to a square viewport: anything wider is horizontal, anything taller is vertical.

All other layout properties (padding, spacing, alignment, sizing modes) are shared between the horizontal and vertical orientation. For per-orientation overrides, assign a ScyllaUILayoutStyle with aspect-ratio breakpoints.

Resolution and orientation changes propagate through the owning ScyllaUILayoutRoot's watcher; without a root the stack's own OnRectTransformDimensionsChange hook fires the dirty mark automatically.

Properties

AspectThreshold

Aspect ratio threshold (width / height) at which the stack flips orientation. Values >= 1 keep landscape horizontal; values < 1 favor vertical layout.

Declaration

public float AspectThreshold { get; set; }

Property Value

Type	Description
float

IsHorizontal

Computed orientation. Returns true (horizontal) when the parent RectTransform's current width / height ratio is at or above AspectThreshold; returns false (vertical) otherwise. Evaluated lazily on every read so the value always reflects the current viewport.

Declaration

public override bool IsHorizontal { get; }

Property Value

Type	Description
bool

Overrides

ScyllaUIStackBase.IsHorizontal

Remarks

When the parent RectTransform is absent, the getter falls back to comparing AspectThreshold against 1.0: if the threshold is 1.0 or below (meaning landscape-or-square is horizontal), the getter returns true; otherwise false. When the parent rect has a non-positive height, the getter returns true (horizontal) as a safe default.
