Subject: [PATCH] Fix PS_AI_Behavior compilation errors for UE 5.5

- Remove NavigationSystem from .uplugin Plugins (it's a module, not a plugin)
- Fix UInterface naming: IPS_AI_Behavior -> IPS_AI_Behavior_Interface (UHT requirement)
- Fix TWeakObjectPtr<AActor> TArray not Blueprint-compatible (remove BlueprintReadOnly)
- Fix UseBlackboard TObjectPtr ref: use raw pointer intermediary
- Fix FEdMode::HandleClick signature: FInputClick -> FViewportClick (UE 5.5)
- Fix SplineNetwork: use OnWorldBeginPlay(UWorld&) override instead of delegate
- Fix PerceptionComponent: remove const from methods calling non-const GetActorsPerception
- Fix EQS SetScore: use 5-arg float overload (Score, FilterMin, FilterMax)
- Fix BTTask_FindCover: add missing Definitions.h include, fix const World
- Fix BTTask_FollowSpline: replace AddWeakLambda with polling in TickTask
- Fix CoverPoint: initialize Color before switch, add default case
- Export LogPS_AI_Behavior with PS_AI_BEHAVIOR_API for cross-module visibility
- Remove unused variables (WorldOrigin, WorldDirection)

+# PS_AI_Behavior — Plan d'implémentation V1
+
+## Vue d'ensemble
+Plugin UE5.5 pour gérer les comportements de NPCs (civils et ennemis) via Behavior Trees, EQS et un système de personnalité à scores. Navigation sur NavMesh, détection d'ennemis, combat basique, fuite, couverture.
+
+Dépendance optionnelle vers PS_AI_ConvAgent (détectée à l'exécution, pas de link-time dependency).

+
+### 2.3 PersonalityComponent (`PS_AI_Behavior_PersonalityComponent.h`)
+
+Attaché au Pawn. Fournit l'accès runtime aux traits, modifie les seuils dynamiquement.
+
+```cpp
+UCLASS(ClassGroup="PS AI Behavior", meta=(BlueprintSpawnableComponent))
+class PS_AI_BEHAVIOR_API UPS_AI_Behavior_PersonalityComponent : public UActorComponent
+{
+    GENERATED_BODY()

+
+    // Threat level perçu (mis à jour par BTService_UpdateThreat)

+    UFUNCTION(BlueprintCallable, Category="PS AI Behavior|Personality")
+    void ModifyTrait(EPS_AI_Behavior_TraitAxis Axis, float Delta);
+};
+```
+
+**Logique `EvaluateReaction()`** :
+```
+EffectiveCourage = RuntimeTraits[Courage] * (1 - PerceivedThreatLevel * 0.5)
+if PerceivedThreatLevel > FleeThreshold * (1 + EffectiveCourage) → Fleeing
+if PerceivedThreatLevel > AttackThreshold * (1 - Aggressivity) → Combat
+if PerceivedThreatLevel > 0.1 → Alerted
+else → Idle/Patrol
+```
+
+### 2.4 AIController (`PS_AI_Behavior_AIController.h`)
+
+```cpp
+UCLASS()
+class PS_AI_BEHAVIOR_API APS_AI_Behavior_AIController : public AAIController
+{
+    GENERATED_BODY()
+public:
+    APS_AI_Behavior_AIController();
+
+    // Blackboard keys (nom constants)
+    static const FName BB_State;            // EPS_AI_Behavior_State
+    static const FName BB_ThreatActor;      // UObject*
+    static const FName BB_ThreatLocation;   // FVector
+    static const FName BB_ThreatLevel;      // float
+    static const FName BB_CoverLocation;    // FVector
+    static const FName BB_PatrolIndex;      // int32
+    static const FName BB_HomeLocation;     // FVector
+
+    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Behavior")
+    UBehaviorTree* BehaviorTreeAsset;
+
+    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Behavior")
+    UBlackboardData* BlackboardAsset;
+
+    // Patrol waypoints (set par level designer ou spawner)
+    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Patrol")
+    TArray<FVector> PatrolPoints;
+
+protected:
+    virtual void OnPossess(APawn* InPawn) override;
+    virtual void OnUnPossess() override;
+
+    // Auto-détection optionnelle de PS_AI_ConvAgent
+    void TryBindConversationAgent();
+};
+```
+
+**`OnPossess`** :
+1. Trouve `PersonalityComponent` sur le Pawn
+2. Crée/initialise le Blackboard
+3. Lit `DefaultBehaviorTree` du ProfileData (ou utilise `BehaviorTreeAsset`)
+4. Lance `RunBehaviorTree()`
+5. Appelle `TryBindConversationAgent()`
+
+**`TryBindConversationAgent()`** :
+- Via `FindComponentByClass` (pas de include direct, utilise `FindObject` ou interface)
+- Si trouvé : bind OnAgentActionRequested pour injecter des actions dans le BT
+
+### 2.5 PerceptionComponent (`PS_AI_Behavior_PerceptionComponent.h`)
+
+Wrapper configuré autour de `UAIPerceptionComponent` :
+
+```cpp
+UCLASS(ClassGroup="PS AI Behavior", meta=(BlueprintSpawnableComponent))
+class PS_AI_BEHAVIOR_API UPS_AI_Behavior_PerceptionComponent : public UAIPerceptionComponent
+{
+    GENERATED_BODY()
+public:
+    UPS_AI_Behavior_PerceptionComponent();
+
+    // Pré-configure : Sight (60m, 90° FOV) + Hearing (30m) + Damage
+    virtual void BeginPlay() override;
+
+    UFUNCTION(BlueprintCallable, Category="PS AI Behavior|Perception")
+    AActor* GetHighestThreat() const;
+
+    UFUNCTION(BlueprintCallable, Category="PS AI Behavior|Perception")
+    float CalculateThreatLevel() const;
+
+protected:
+    UFUNCTION()
+    void OnPerceptionUpdated(const TArray<AActor*>& UpdatedActors);
+};
+```
+
+### 2.6 CombatComponent (`PS_AI_Behavior_CombatComponent.h`)
+
+Gère l'état combat, les distances, le cooldown d'attaque :
+
+```cpp
+UCLASS(ClassGroup="PS AI Behavior", meta=(BlueprintSpawnableComponent))
+class PS_AI_BEHAVIOR_API UPS_AI_Behavior_CombatComponent : public UActorComponent
+{
+    GENERATED_BODY()
+public:
+    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Combat")
+    float AttackRange = 200.0f;
+
+    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Combat")
+    float AttackCooldown = 1.5f;
+
+    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Combat")
+    float AttackDamage = 20.0f;
+
+    UFUNCTION(BlueprintCallable, Category="PS AI Behavior|Combat")
+    bool CanAttack() const;
+
+    UFUNCTION(BlueprintCallable, Category="PS AI Behavior|Combat")
+    void ExecuteAttack(AActor* Target);
+
+    UFUNCTION(BlueprintCallable, Category="PS AI Behavior|Combat")
+    bool IsInAttackRange(AActor* Target) const;
+};
+```
+
+---
+
+## 3. Behavior Tree — Nodes
+
+### 3.1 Services (tournent en continu)
+
+**BTService_UpdateThreat** :
+- Lit `PerceptionComponent::CalculateThreatLevel()`
+- Écrit `BB_ThreatLevel`, `BB_ThreatActor`, `BB_ThreatLocation`
+- Met à jour `PersonalityComponent::PerceivedThreatLevel`
+
+**BTService_EvaluateReaction** :
+- Appelle `PersonalityComponent::EvaluateReaction()`
+- Écrit `BB_State` dans le Blackboard
+- Le BT utilise des decorators pour brancher sur cet état
+
+### 3.2 Tasks
+
+**BTTask_Patrol** :
+- Lit `BB_PatrolIndex`, navigue vers `PatrolPoints[idx]`
+- Au succès, incrémente l'index (cyclique)
+- Supporte pause aléatoire aux waypoints
+
+**BTTask_FleeFrom** :
+- Lit `BB_ThreatLocation`
+- Utilise EQS `EQS_FindFleePoint` (direction opposée à la menace)
+- `MoveTo()` vers le point trouvé
+
+**BTTask_FindCover** :
+- Lance EQS `EQS_FindCover` (scoring : distance menace, line-of-sight block, distance au NPC)
+- Navigue vers le meilleur point
+- Écrit `BB_CoverLocation`
+
+**BTTask_Attack** :
+- Vérifie `CombatComponent::CanAttack()`
+- Si hors range : `MoveTo(Target)`
+- Si in range : `CombatComponent::ExecuteAttack(Target)`
+
+### 3.3 Decorators
+
+**BTDecorator_CheckTrait** :
+- Paramètres : `TraitAxis`, `ComparisonOp` (>, <, ==), `Threshold`
+- Lit le trait depuis `PersonalityComponent`
+- Exemple : "Exécuter seulement si Courage > 0.5"
+
+---
+
+## 4. EQS
+
+### EQS_FindCover
+- **Generator** : Points sur grille autour du NPC (rayon 15m)
+- **Tests** :
+  - Distance à la menace (préfère mi-distance, pas trop loin)
+  - Trace visibility (préfère les points non-visibles depuis la menace)
+  - Distance au NPC (préfère les points proches)
+  - `EQSTest_CoverQuality` (custom) : raycasts multiples pour évaluer la qualité de couverture
+
+### EQS_FindFleePoint
+- **Generator** : Points sur donut (rayon 10-25m)
+- **Tests** :
+  - Dot product direction (opposé à la menace : score max)
+  - PathExistence (doit être atteignable sur NavMesh)
+  - Distance à la menace (préfère loin)
+
+### EQS_FindPatrolPoint
+- **Generator** : Points depuis la liste PatrolPoints de l'AIController
+- **Tests** :
+  - Distance au NPC (préfère le plus proche non-visité)
+
+### EQSContext_Threat
+- Renvoie l'acteur/location de `BB_ThreatActor` / `BB_ThreatLocation`
+
+---
+
+## 5. Intégration optionnelle PS_AI_ConvAgent
+
+**Mécanisme** : Pas de `#include` direct. L'AIController utilise `FindComponentByClass` avec le nom de classe via UObject reflection :
+
+```cpp
+void APS_AI_Behavior_AIController::TryBindConversationAgent()
+{
+    // Soft reference — no link-time dependency
+    UActorComponent* ConvComp = GetPawn()->FindComponentByClass(
+        LoadClass<UActorComponent>(nullptr,
+            TEXT("/Script/PS_AI_ConvAgent.PS_AI_ConvAgent_ElevenLabsComponent")));
+    if (ConvComp)
+    {
+        // Bind to OnAgentActionRequested via dynamic delegate
+        // Actions from conversation can inject BT state changes
+    }
+}
+```
+
+Cela permet :
+- Un NPC conversationnel qui reçoit "Fuis !" via ElevenLabs → injecte State=Fleeing dans le BT
+- Aucune dépendance de compilation
+
+---
+
+## 6. Build.cs — Dépendances
+
+```csharp
+// PS_AI_Behavior.Build.cs
+PublicDependencyModuleNames.AddRange(new string[] {
+    "Core", "CoreUObject", "Engine",
+    "AIModule",                  // AAIController, BehaviorTree, Blackboard
+    "GameplayTasks",             // UGameplayTask (requis par BT tasks)
+    "NavigationSystem",          // NavMesh queries
+});
+
+PrivateDependencyModuleNames.AddRange(new string[] {
+    "Settings",                  // ISettingsModule
+});
+
+// PAS de dépendance vers PS_AI_ConvAgent
+```
+

+
+## 7. Ordre d'implémentation (étapes)
+
+### Étape 1 — Squelette plugin
+- [ ] Créer la structure de fichiers du plugin
+- [ ] `.uplugin`, `Build.cs`, module class

+- [ ] `Settings.h/cpp` (settings vides pour l'instant)
+- [ ] Ajouter au `.uproject`
+- [ ] **Vérification** : compile sans erreur
+
+### Étape 2 — Personality System
+- [ ] `PersonalityProfile` (Data Asset)
+- [ ] `PersonalityComponent` avec `EvaluateReaction()`
+- [ ] **Vérification** : peut créer un Data Asset dans l'éditeur, lire les traits en BP
+
+### Étape 3 — AIController + Perception
+- [ ] `PS_AI_Behavior_AIController` avec Blackboard setup
+- [ ] `PS_AI_Behavior_PerceptionComponent` (sight + hearing)
+- [ ] `BlackboardData` asset par défaut
+- [ ] **Vérification** : un NPC spawné détecte les acteurs proches
+
+### Étape 4 — BT Services + Decorators
+- [ ] `BTService_UpdateThreat`
+- [ ] `BTService_EvaluateReaction`
+- [ ] `BTDecorator_CheckTrait`
+- [ ] **Vérification** : le Blackboard se met à jour en jeu
+
+### Étape 5 — BT Tasks (Navigation)
+- [ ] `BTTask_Patrol`
+- [ ] `BTTask_FleeFrom`
+- [ ] `BTTask_FindCover`
+- [ ] **Vérification** : NPC patrouille et fuit
+
+### Étape 6 — Combat
+- [ ] `CombatComponent`
+- [ ] `BTTask_Attack`
+- [ ] **Vérification** : NPC ennemi attaque le joueur
+
+### Étape 7 — EQS
+- [ ] `EQSContext_Threat`
+- [ ] `EQSTest_CoverQuality`
+- [ ] Assets EQS dans Content/
+- [ ] **Vérification** : NPC trouve des couvertures intelligemment
+
+### Étape 8 — Intégration ConvAgent (optionnelle)
+- [ ] `TryBindConversationAgent()` soft binding
+- [ ] Test avec un NPC qui a les deux plugins
+
