Class UiAnchorMapper

Pure mapping from a UiAnchorType to normalized per-axis placement factors — the single source for every "which corner/edge does this anchor mean" switch. A factor of 0/0.5/1 places the element at the start/center/end of the axis: horizontally 0 = left and 1 = right; vertically the Unity-pivot convention is used, 0 = bottom and 1 = top.

Syntax

public static class UiAnchorMapper

Remarks

Engine-free so the Menu runtime (pivot/position math) and Ui editor tooling (preview placement) both derive their anchor handling from here instead of re-encoding the nine-case switch.

Methods

HorizontalFactor(UiAnchorType)

The horizontal placement factor: 0 = left edge, 0.5 = center, 1 = right edge.

Declaration

public static float HorizontalFactor(UiAnchorType anchor)

Parameters

Type	Name	Description
UiAnchorType	anchor	The anchor to map.

Returns

Type	Description
float	The normalized horizontal factor.

IsBottom(UiAnchorType)

Whether the anchor sits on the bottom edge.

Declaration

public static bool IsBottom(UiAnchorType anchor)

Parameters

Type	Name	Description
UiAnchorType	anchor	The anchor to test.

Returns

Type	Description
bool	True for BOTTOM/BOTTOM_LEFT/BOTTOM_RIGHT.

VerticalFactor(UiAnchorType)

The vertical placement factor (Unity pivot convention): 0 = bottom edge, 0.5 = center, 1 = top edge.

Declaration

public static float VerticalFactor(UiAnchorType anchor)

Parameters

Type	Name	Description
UiAnchorType	anchor	The anchor to map.

Returns

Type	Description
float	The normalized vertical factor.
