DataFieldOverrideDrawer

Odin property drawer for DataFieldOverride. Renders the override's value using its child Value property and appends a red delete button that removes the override from its parent DataOverride dictionary.

Definition

Namespace: Paragon.Core.ScriptableFactory.Editor Assembly: Paragon.Editor.dll

[DrawerPriority(0.0, 0.0, 3000.0)]
public class DataFieldOverrideDrawer : OdinValueDrawer<DataFieldOverride>

Inherits: OdinValueDrawer<DataFieldOverride> (Sirenix.OdinInspector.Editor)

Remarks

This is the leaf-level drawer in the variant editor hierarchy. Each instance renders a single field override value alongside a trash icon button for removal. It is drawn by DataOverrideDrawer for each entry in the fieldOverrides dictionary.

The drawer consists of two horizontal sections:

1. Value field — The Value child property is drawn using its own Odin drawer (which adapts to the field's actual type — float, int, string, etc.). Indentation from the property tree is respected.

2. Delete button — A small red trash icon button (17 x 18 px) that, when clicked, finds the parent fieldOverrides dictionary and removes the current override by its FieldName.

Fields

dataFieldOverride

Cached reference to the DataFieldOverride instance being drawn.

private DataFieldOverride dataFieldOverride;

valueProperty

Cached reference to the Value child property of the DataFieldOverride.

private InspectorProperty valueProperty;

Methods

Initialize

Caches the DataFieldOverride reference from ValueEntry.SmartValue and resolves the Value child property.

protected override void Initialize()

DrawPropertyLayout

Main entry point called by Odin. Draws the value field and delete button in a horizontal toolbar.

protected override void DrawPropertyLayout(GUIContent label)

Parameter	Type	Description
label	GUIContent	Label provided by the parent drawer (typically the field name from DataOverrideDrawer).

Behavior:

1. Opens a horizontal toolbar layout.

2. Checks indentation via valueProperty.GetCurrentDrawerIndentation() and applies spacing.

3. Draws the Value property with the provided label inside a vertical layout.

4. Calls DrawControls() to render the delete button.

DrawControls

Draws the red trash icon button. On click, traverses up the property tree to find the fieldOverrides dictionary and removes the current override by FieldName.

private void DrawControls()

Behavior:

• Colorizes the button background red via DrawGUI.ColorizeBackground(Color.red).

• Uses FindParentWithName("fieldOverrides") to locate the owning dictionary.

• Casts the dictionary to Dictionary<string, DataFieldOverride> and calls Remove(dataFieldOverride.FieldName).

Common Pitfalls

Parent property traversal The delete button relies on FindParentWithName("fieldOverrides") to locate the owning dictionary. If the property tree structure changes (e.g., wrapping DataOverride in a custom container), this traversal may fail to find the parent.

Direct dictionary mutation The delete operation directly mutates the fieldOverrides dictionary via Remove(). Odin detects this change and refreshes the property tree, but the removal is not undoable via Unity's Undo system.
