Integration Points

With Existing Systems

BotAI Integration:

void BotAI::UpdateAI(uint32 diff)
{
    // Movement
    MovementManager::Instance()->UpdateMovement(GetBot(), diff);

    // NPC Interaction
    if (NearNPC())
        InteractionManager::Instance()->InteractWithNPC(GetBot(), GetNearestNPC());

    // Quest System
    QuestCompletion::instance()->UpdateQuestProgress(GetBot());
    if (HasCompletableQuest())
        QuestTurnIn::instance()->TurnInQuest(questId, GetBot());
}

Combat System Integration:

• Movement system coordinates with PositionManager for combat positioning
• Quest system uses TargetSelector for quest mob prioritization
• Threat management integration for quest objectives

Performance System Integration:

• All systems use ThreadPool for async operations
• MemoryPool used for path storage and quest data
• QueryOptimizer for database queries
• Profiler for performance monitoring
