Many Unity systems use this pattern (e.g., Unity's own UI system with `Selectable` as base for `Button`, `Toggle`, etc.) + +#### Concern: "Existing prefabs will break" +**Mitigation**: +- Use `[FormerlySerializedAs]` and script migration utilities +- The class GUIDs remain the same if we rename properly +- Test thoroughly with existing prefabs + +#### Concern: "Losing flexibility of composition" +**Mitigation**: +- We're keeping the action component system (InteractionActionBase) for cross-cutting concerns +- UnityEvents still allow designers to hook up custom behavior +- This is specifically for the "interaction completion decision" logic + +#### Concern: "Pickup and ItemSlot share code currently" +**Mitigation**: +- ItemSlot already extends Pickup, so inheritance hierarchy already exists +- This actually formalizes and improves that relationship + +### What Stays the Same + +1. **Action Component System** - `InteractionActionBase` and `InteractionTimelineAction` remain unchanged +2. **UnityEvents** - All UnityEvent fields remain for designer use +3. **Character Movement** - All the movement orchestration logic stays in base +4. **Event Dispatching** - The async event dispatch system to action components stays +5. **CharacterMoveToTarget** - Helper component continues to work +6. **ITouchInputConsumer** - Interface implementation stays + +### Recommendation + +**Proceed with the refactoring** for these reasons: + +1. The current composition pattern is creating artificial separation where none is needed +2. Classes that "decide when interaction is complete" ARE fundamentally different types of interactions +3. The inheritance hierarchy is shallow (2-3 levels max) and logical +4. The action component system handles the "aspects that cut across interactions" well +5. This matches Unity's own design patterns (see UI system) +6. Code will be more maintainable and easier to understand + +The key insight is: **Pickup, ItemSlot, and OneClickInteraction aren't "helpers" for Interactable - they ARE different kinds of Interactables.** The inheritance model reflects this reality better than composition. + diff --git a/docs/ManagedBehaviour_Implementation_Guide.md b/docs/ManagedBehaviour_Implementation_Guide.md new file mode 100644 index 00000000..a5a05d13 --- /dev/null +++ b/docs/ManagedBehaviour_Implementation_Guide.md @@ -0,0 +1,1436 @@ +# ManagedBehaviour Lifecycle System - Implementation Guide + +## Overview +This document provides a step-by-step implementation plan for creating a custom lifecycle management system that extends MonoBehaviour with deterministic, ordered lifecycle hooks.
