Create namespace `Core.Lifecycle` -2. Define `LifecyclePhase` enum with all phases -3. Define `LifecycleFlags` enum for component opt-in (bitflags) -4. Add XML documentation for each value - -**Key Details**: -- LifecyclePhase: ManagedAwake, BootComplete, SceneReady, Update, FixedUpdate, Paused, Resumed, SceneUnloading, ManagedDestroy -- LifecycleFlags: None, ManagedAwake, BootComplete, SceneReady, ManagedUpdate, ManagedFixedUpdate, Pause, SceneUnloading, ManagedDestroy, All (bitwise OR of all) - ---- - -### STEP 2: Create ManagedEvent System -**File**: `Assets/Scripts/Core/Lifecycle/ManagedEventSubscription.cs` - -**Actions**: -1. Create internal struct `ManagedEventSubscription` to store event delegate and target -2. Create class `ManagedEventManager` with: - - List of subscriptions per ManagedBehaviour - - `RegisterEvent(target, action)` method - - `UnregisterAllEvents()` method that invokes `-=` on all stored subscriptions -3. Handle both `Action` and generic `Action` delegates -4. Use reflection to dynamically unsubscribe - -**Key Details**: -- Store event info as: object target (event owner), Delegate handler, string eventName -- Support common Unity event patterns (Action, Action\, UnityEvent, etc.) -- Provide safe null checks before unsubscribing - ---- - -### STEP 3: Create ManagedBehaviour Base Class (Structure) -**File**: `Assets/Scripts/Core/Lifecycle/ManagedBehaviour.cs` - -**Actions**: -1. Create abstract class `ManagedBehaviour : MonoBehaviour` -2. Add virtual properties for priorities: - - `ManagedAwakePriority` (default 100) - - `BootCompletePriority` (default 100) - - `SceneReadyPriority` (default 100) - - `UpdatePriority` (default 100) - - `DestroyPriority` (default 100) -3. Add property `ActiveLifecyclePhases` (returns LifecycleFlags, default None) -4. Add property `AutoRegisterSaveParticipant` (default false) -5. Add property `AutoRegisterPausable` (default false) -6. Add property `IsPersistent` (default false) - survives scene changes -7. Add private field `ManagedEventManager _eventManager` -8. Add private bool `_isRegistered` to track registration state - -**Key Details**: -- All priority properties are virtual so subclasses can override -- ActiveLifecyclePhases determines which hooks are called (opt-in) -- IsPersistent flag controls whether component persists across scenes - ---- - -### STEP 4: Implement ManagedBehaviour Lifecycle Hooks (Virtual Methods) -**File**: `Assets/Scripts/Core/Lifecycle/ManagedBehaviour.cs` (continued) - -**Actions**: -1. Add virtual protected methods (empty by default): - - `OnManagedAwake()` - - `OnBootComplete()` - - `OnSceneReady()` - - `OnManagedUpdate()` - - `OnManagedFixedUpdate()` - - `OnPaused()` - - `OnResumed()` - - `OnSceneUnloading()` - - `OnManagedDestroy()` -2. Add XML documentation for each method -3.

Implement `protected virtual void Awake()`: - - Initialize _eventManager - - Register with LifecycleManager (call `LifecycleManager.Instance.Register(this)`) - - Set _isRegistered = true -2. Implement `protected virtual void OnDestroy()`: - - Unregister from LifecycleManager (call `LifecycleManager.Instance.Unregister(this)`) - - Call _eventManager.UnregisterAllEvents() - - Auto-unregister from SaveLoadManager and GameManager if applicable - - Set _isRegistered = false -3. Make both methods call base implementation warning (for subclasses) - -**Key Details**: -- Use null checks for LifecycleManager.Instance (may not exist during shutdown) -- Provide clear error logging if registration fails -- Support scenario where subclass overrides Awake/OnDestroy (must call base) - ---- - -### STEP 6: Create LifecycleManager (Structure) -**File**: `Assets/Scripts/Core/Lifecycle/LifecycleManager.cs` - -**Actions**: -1. Create class `LifecycleManager : MonoBehaviour` -2. Implement singleton pattern (private static _instance, public static Instance) -3. Add separate `List` for each lifecycle phase: - - `_managedAwakeList` - - `_bootCompleteList` - - `_sceneReadyList` - - `_updateList` - - `_fixedUpdateList` - - `_pauseList` - - `_sceneUnloadingList` - - `_destroyList` -4. Add Dictionary for tracking which lists each component is in (bitmask) -5. Add bool flags: `_isBootComplete`, `_isSceneReady`, `_isPaused` -6. Add queue for late registrations: `Queue _pendingRegistrations` - -**Key Details**: -- Each list must be kept sorted by priority -- Use SortedList or List with manual sorting after registration -- Dictionary tracks which phases each component participates in - ---- - -### STEP 7: Implement LifecycleManager Registration System -**File**: `Assets/Scripts/Core/Lifecycle/LifecycleManager.cs` (continued) - -**Actions**: -1. Implement `public void Register(ManagedBehaviour component)`: - - Check component.ActiveLifecyclePhases flags - - Add to appropriate lists based on flags - - Insert in priority-sorted position - - Handle auto-registration with SaveLoadManager if component is ISaveParticipant && AutoRegisterSaveParticipant - - Handle auto-registration with GameManager if component is IPausable && AutoRegisterPausable - - If boot already complete and component has BootComplete flag, immediately call OnBootComplete - - If scene already ready and component has SceneReady flag, immediately call OnSceneReady -2. Implement `public void Unregister(ManagedBehaviour component)`: - - Remove from all lists - - Handle auto-unregistration from SaveLoadManager and GameManager - -**Key Details**: -- Use binary search for insertion point (lists sorted by priority) -- Handle edge case: registration during broadcast (queue and process later) -- Validate component is not null and has valid priorities - ---- - -### STEP 8: Implement LifecycleManager Broadcast System -**File**: `Assets/Scripts/Core/Lifecycle/LifecycleManager.cs` (continued) - -**Actions**: -1.
