InteractionTriggerDrawer

Custom Odin Inspector drawer for InteractionTrigger values. Renders polymorphic trigger instances with a foldable header, type-selection field for null values, and indented child properties.

Definition

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

[DrawerPriority(0.0, 0.0, 3000.0)]
public class InteractionTriggerDrawer : OdinValueDrawer<InteractionTrigger>

Inheritance: OdinValueDrawer<InteractionTrigger> → InteractionTriggerDrawer

Remarks

This drawer handles three visual states for an InteractionTrigger property:

1. Null — Shows a "New Trigger" label with a polymorphic object field for type selection. The foldout is collapsed.

2. Non-null with children — Shows a foldable header displaying the nicified type name (e.g., "My Custom Trigger" from MyCustomTrigger). Children are drawn indented inside a vertical toolbar.

3. Non-null without children — Shows the type name as a flat label with no foldout.

The drawer priority is set to 3000.0 on the wrapper layer, ensuring it overrides default Odin drawers for InteractionTrigger.

Methods

DrawPropertyLayout (override)

Main draw method. Renders the trigger inside a vertical toolbar with header and optional children.

protected override void DrawPropertyLayout(GUIContent label)

Parameter	Type	Description
label	GUIContent	The property label (unused — trigger renders its own header)

DrawHeader (private)

Renders the header bar. Handles null state (polymorphic field), foldout state, and flat label state.

Visual Layout

┌─────────────────────────────────┐  ← Vertical Toolbar
│ ▼ My Custom Trigger            │  ← Header (foldout or label)
│   ┌─────────────────────────┐  │
│   │ [Child properties...]   │  │  ← Indented children (9px)
│   └─────────────────────────┘  │
└─────────────────────────────────┘

When null:

┌─────────────────────────────────┐
│ New Trigger  [Type Selector ▾]  │  ← Polymorphic object field
└─────────────────────────────────┘

Common Pitfalls

Polymorphic field creates instances — The SirenixEditorFields.PolymorphicObjectField call creates a new trigger instance when a type is selected. The created instance uses the default constructor.

Type name formatting — Uses ObjectNames.NicifyVariableName() to convert PascalCase type names to readable labels (e.g., ProximityTrigger → "Proximity Trigger").
