Editor

Custom Unity Editor tooling for the Action System. Provides property drawers and custom inspectors that enable polymorphic selection, foldable bodies, progress indicators, and play/stop controls for actions directly in the Unity Inspector.

Architecture

Editor Components

Component	Type	Draws	Purpose
ActionDrawer<TAction>	Property Drawer	Action	Polymorphic action selector with foldable body and progress indicator
ActionPlayerEditor	Custom Editor	ActionPlayer	Adds Play/Stop buttons to the ActionPlayer inspector
ActionSequenceDrawer<TActionSequence>	Property Drawer	ActionSequence	Extends ActionDrawer to show the sequence list alongside action variables

Drawer Hierarchy

The editor drawers mirror the runtime inheritance chain:

Key Patterns

Drawer Priority System

Odin uses [DrawerPriority] to resolve which drawer handles a given type. Higher priority wins:

Drawer	Priority	Constraint
ActionDrawer<TAction>	(0, 0, 3000)	where TAction : Action
ActionSequenceDrawer<TActionSequence>	(0, 0, 3005)	where TActionSequence : ActionSequence

ActionSequenceDrawer has a higher priority than ActionDrawer, so Odin picks it for ActionSequence fields while ActionDrawer handles all other Action fields.

Polymorphic Object Field

All action drawers use SirenixEditorFields.PolymorphicObjectField() in the header, which provides a dropdown to select any concrete Action subclass. This enables Inspector-driven type switching without custom code.

Extension Pattern

To create a custom drawer for a new Action subclass:

using UnityEngine;
using Sirenix.OdinInspector.Editor;
using Paragon.Core.ActionSystem.Editor;

// Priority must be higher than ActionDrawer (3000)
[DrawerPriority(0.0, 0.0, 3010.0)]
public class MyCustomActionDrawer<T> : ActionDrawer<T> where T : MyCustomAction
{
    protected override GUIContent defaultLabel { get; } = new GUIContent("My Custom Action");

    protected override void DrawBody()
    {
        // Custom body drawing
        base.DrawBody();
    }
}
