InteractionConditionDrawer

Odin value drawer for InteractionCondition. Renders each condition as a foldable toolbar panel with a polymorphic type selector for null entries and a negate toggle button.

Definition

Namespace: Paragon.Townskeep.InteractionSystem.Editor Assembly: Townskeep.Editor.dll

[DrawerPriority(0.0, 0.0, 3000.0), UsedImplicitly]
public class InteractionConditionDrawer : OdinValueDrawer<InteractionCondition>

Inheritance: OdinValueDrawer<InteractionCondition> → InteractionConditionDrawer

Remarks

This drawer provides a custom Inspector rendering for InteractionCondition instances within the conditions list of an InteractionContext. It handles three distinct visual states:

Visual States

State	Rendering
Null condition	Shows "New Condition" label with a polymorphic type selector field (PolymorphicObjectField)
Condition with no custom fields	Shows the nicified type name as a flat label (no foldout, nothing to expand)
Condition with custom fields	Shows a foldable panel with the type name as header, child fields drawn inside

Negate Toggle

Every condition displays a negate button (exclamation mark icon) in the header toolbar. When the negate flag is active, the button renders in red (Color(1, 0.2, 0.2, 1)), providing clear visual feedback that the condition result is inverted.

The negate property is drawn as a toggle button and excluded from the child property iteration to avoid rendering it twice.

Drawer Priority

The [DrawerPriority(0.0, 0.0, 3000.0)] ensures this drawer takes precedence over Odin's default polymorphic drawer for InteractionCondition values.

Quick Lookup

Goal	How
Create a new condition	Leave the field null — polymorphic selector appears
Toggle negate	Click the exclamation mark icon in the condition header
Expand/collapse fields	Click the foldout arrow (only visible when the condition has custom fields)

Methods

Initialize (override)

Caches the negate child property for the toggle button rendering.

protected override void Initialize()

DrawPropertyLayout (override)

Main drawing method. Renders the condition panel with header, negate button, and expandable child fields.

protected override void DrawPropertyLayout(GUIContent label)

Parameter	Type	Description
label	GUIContent	The label for this property (typically unused)

Common Pitfalls

Negate property excluded from children The drawer explicitly skips drawing the negate child property in the body because it renders it as a toolbar icon button. If the negate field is renamed in InteractionCondition, this drawer will break (it resolves by name: Property.Children["negate"]).

PolymorphicObjectField for null entries When the condition is null, SirenixEditorFields.PolymorphicObjectField is used to present a type selector. This requires that condition subclasses are marked [Serializable] and are discoverable by Odin.
