BindingPath - the Unity Input System binding path string (e.g., "<Gamepad>/buttonSouth").
Icon - an optional UnityEngine.Sprite shown as a thumbnail preview.
DisplayText - a short fallback label (e.g., "A", "Space") used when no sprite icon is available.

The full-height element layout places the sprite preview on the left and the three text/object fields stacked on the right. The compact single-line layout is used for collapsed or summarized views. Element height is calculated by GetElementHeight() and must be returned from the list's elementHeightCallback delegate.

An inline warning indicator ("!") is shown next to the binding-path field when the path is empty.

Fields

DELETE_BUTTON_WIDTH

Reserved pixel width for the per-row delete button (not drawn by this class directly; available for callers that manage their own delete buttons alongside this drawer).

Declaration

public const float DELETE_BUTTON_WIDTH = 20

Field Value

Type	Description
float

FIELD_SPACING

Horizontal gap in pixels between the sprite preview and the text/object fields.

Declaration

public const float FIELD_SPACING = 4

Field Value

Type	Description
float

LABEL_WIDTH

Reserved label column width in pixels for display-name style fields within the mapping entry (not currently used in the main draw path; available for external callers).

Declaration

public const float LABEL_WIDTH = 50

Field Value

Type	Description
float

SPRITE_SIZE

Width and height in pixels of the square sprite thumbnail drawn on the left side of each full-height DrawElement(Rect, SerializedProperty, int, bool, bool) row.

Declaration

public const float SPRITE_SIZE = 48

Field Value

Type	Description
float

Methods

DrawCompact(Rect, SerializedProperty)

Draws a compact single-line read-only preview of an IconMapping entry, showing a small sprite thumbnail scaled to fit the row height, the binding path in muted style, and the display text in bold style.

Declaration

public static void DrawCompact(Rect rect, SerializedProperty element)

Parameters

Type	Name	Description
Rect	rect	The bounding UnityEngine.Rect for the single-line row. The height determines the size of the inline sprite thumbnail.
SerializedProperty	element	The UnityEditor.SerializedProperty for the `IconMapping` struct. Must have child properties `BindingPath`, `Icon`, and `DisplayText`. If null, the method returns immediately without drawing anything.

DrawElement(Rect, SerializedProperty, int, bool, bool)

Draws a full-height IconMapping element inside a ReorderableList, rendering a sprite thumbnail on the left and - stacked vertically on the right - an editable binding-path field, an editable display-text field, and a sprite object field.

Declaration

public static void DrawElement(Rect rect, SerializedProperty element, int index, bool isActive, bool isFocused)

Parameters

Type	Name	Description
Rect	rect	The bounding UnityEngine.Rect provided by the `ReorderableList` `drawElementCallback`. The height is expected to match the value returned by GetElementHeight().
SerializedProperty	element	The UnityEditor.SerializedProperty for the `IconMapping` struct at the current list index. Must have child properties `BindingPath`, `Icon`, and `DisplayText`. If null, the method returns immediately without drawing anything.
int	index	The zero-based index of this element in the list (reserved for future use).
bool	isActive	true when this element is selected in the list (reserved for future selection-highlight rendering).
bool	isFocused	true when this element has keyboard focus (reserved for future focus-highlight rendering).

GetElementHeight()

Returns the required element height in pixels for a full-height IconMapping row, accounting for three stacked fields (binding path, display text, and icon object field) and ensuring the row is at least as tall as the SPRITE_SIZE thumbnail.

Declaration

public static float GetElementHeight()

Returns

Type	Description
float	The greater of the sprite thumbnail height and the combined three-field column height, plus Scylla.Input.Editor.IconMappingDrawer.ELEMENT_PADDING for vertical breathing room.
