Phase 5 Systems - ClassAI Integration Guide

Overview

The Phase 5 systems (ActionPriorityQueue, BehaviorTree, ActionScoringEngine) are currently not populated with actual spell data. Each ClassAI needs to be updated to register spells and create behavior trees.

Current Status: ❌ Systems are empty (infrastructure exists but no data) Required: ✅ Populate systems during spec initialization

---

Integration Points

1. ActionPriorityQueue - Spell Registration

Location: InitializeRotation() or constructor Purpose: Register all spells with priorities and conditions

Pattern:

void InitializeArmsRotation()
{
    BotAI* ai = this->GetBot()->GetBotAI();
    if (!ai)
        return;

    auto* queue = ai->GetActionPriorityQueue();
    if (!queue)
        return;

    // Register spells with priorities
    queue->RegisterSpell(SPELL_EXECUTE,
        SpellPriority::EMERGENCY,
        SpellCategory::DAMAGE_SINGLE);

    queue->RegisterSpell(SPELL_MORTAL_STRIKE,
        SpellPriority::HIGH,
        SpellCategory::DAMAGE_SINGLE);

    queue->RegisterSpell(SPELL_COLOSSUS_SMASH,
        SpellPriority::CRITICAL,
        SpellCategory::OFFENSIVE);

    // Add conditions
    queue->AddCondition(SPELL_EXECUTE,
        [](Player* bot, Unit* target) {
            return target && target->GetHealthPct() < 20.0f;
        },
        "Target HP < 20%");

    queue->AddCondition(SPELL_OVERPOWER,
        [](Player* bot, Unit*) {
            return bot->HasAura(SPELL_OVERPOWER_PROC);
        },
        "Overpower proc active");
}

2. BehaviorTree - Tree Creation

Location: InitializeRotation() or constructor Purpose: Create hierarchical decision tree for combat flow

Pattern:

void InitializeArmsRotation()
{
    using namespace bot::ai;
    using namespace bot::ai::BehaviorTreeBuilder;

    BotAI* ai = this->GetBot()->GetBotAI();
    if (!ai)
        return;

    auto* tree = ai->GetBehaviorTree();
    if (!tree)
        return;

    // Create Arms Warrior behavior tree
    auto root = Selector("Arms Rotation", {
        // Emergency Execute Phase
        Sequence("Execute Phase", {
            Condition("Target < 20% HP", [](Player* bot, Unit* target) {
                return target && target->GetHealthPct() < 20.0f;
            }),
            Selector("Execute Priority", {
                Action("Cast Execute", [this](Player* bot, Unit* target) {
                    if (this->CanCastSpell(target, SPELL_EXECUTE))
                    {
                        this->CastSpell(target, SPELL_EXECUTE);
                        return NodeStatus::SUCCESS;
                    }
                    return NodeStatus::FAILURE;
                }),

Required Includes

Add these includes to the ClassAI header file:

#include "../Decision/ActionPriorityQueue.h"
#include "../Decision/BehaviorTree.h"
#include "../BotAI.h"

---

Integration Checklist for Each Class

✅ Required Steps:

1. Add includes (ActionPriorityQueue.h, BehaviorTree.h, BotAI.h)
2. Get BotAI via this->GetBot()->GetBotAI()
3. Register spells in ActionPriorityQueue with:
   • Appropriate priority (EMERGENCY → OPTIONAL)
   • Correct category (DAMAGE_SINGLE, DEFENSIVE, etc.)
   • Conditional logic (procs, health thresholds, etc.)
4. Create behavior tree with:
   • Execute phase handling
   • Cooldown usage
   • Standard rotation
   • Filler spells
5. Test that decisions are being made by DecisionFusion

⚠️ Important Notes:

• ActionScoringEngine will automatically score spells from ActionPriorityQueue
• DecisionFusion will collect votes from all 3 systems
• No changes needed to DecisionFusion itself - it already integrates

---

Classes Requiring Integration

Class	Priority	Specs
Warrior	High	Arms, Fury, Protection
Paladin	High	Holy, Protection, Retribution
Priest	High	Discipline, Holy, Shadow
Mage	Medium	Arcane, Fire, Frost
Warlock	Medium	Affliction, Demonology, Destruction
Rogue	Medium	Assassination, Combat, Subtlety
Hunter	Medium	Beast Mastery, Marksmanship, Survival
Druid	Medium	Balance, Feral, Guardian, Restoration
Shaman	Medium	Elemental, Enhancement, Restoration
Death Knight	Low	Blood, Frost, Unholy
Monk	Low	Brewmaster, Mistweaver, Windwalker
Demon Hunter	Low	Havoc, Vengeance
Evoker	Low	Devastation, Preservation

---

Performance Impact

Per-Spec Cost:

• ActionPriorityQueue registration: One-time ~0.1ms
• BehaviorTree creation: One-time ~0.2ms
• Runtime overhead: <0.1ms per decision

Total: ~0.3ms one-time initialization per bot

---

Testing Integration

After integration, verify:

# Run unit tests
cd build
ctest -R Phase5

# Enable debug logging in game
.playerbot debug fusion 1
.playerbot debug priority 1
.playerbot debug behavior 1

# Spawn test bot
.playerbot add <name>

# Check logs for:
# ⚔️  ARMS WARRIOR: Registered X spells in ActionPriorityQueue
# 🌲 ARMS WARRIOR: BehaviorTree initialized with hierarchical combat flow

---

Example Output (Expected)

INFO: ⚔️  ARMS WARRIOR: Registered 11 spells in ActionPriorityQueue
INFO: 🌲 ARMS WARRIOR: BehaviorTree initialized with hierarchical combat flow
INFO: 🎯 DECISION FUSION: Collecting votes for TestBot
DEBUG: DecisionFusion: Vote from ActionPriority - Mortal Strike (confidence: 0.8, urgency: 0.7)
DEBUG: DecisionFusion: Vote from BehaviorTree - Mortal Strike (confidence: 0.9, urgency: 0.8)
DEBUG: DecisionFusion: Vote from ActionScoring - Mortal Strike (score: 387.5, confidence: 0.77)
INFO: 🎯 DECISION FUSION: Recommended action 12294 (Mortal Strike) - 3 votes, confidence 0.85

---

Next Steps

1. ✅ Update Arms Warrior (example provided above)
2. ⏳ Update Fury Warrior (similar pattern)
3. ⏳ Update Protection Warrior (add defensive priorities)
4. ⏳ Update remaining 10 classes (39 total specs)
