# Combat System Setup Complete ✅

I've set up a complete foundation for agent combat, monsters, and equipment. Here's what you got:

## What's Been Created

### Core Systems (8 new classes)
1. **CharacterStats** — Base stats (health, speed, attack, defense, magic)
2. **CharacterSheet** — Equipment + stat bonuses management
3. **Item, Weapon, Armor** — Equipment system with automatic bonuses
4. **Monster** — ScriptableObject templates for spawning monsters
5. **MonsterEncounter** — Manages monsters in a room with partial info
6. **RoomEncounterConfig** — Configuration for encounter spawning
7. **CombatResolver** — Skeleton for combat resolution (you'll expand this)
8. **AutonomousAgentBrain** — Updated with peek & retreat mechanics

### Updated Existing Classes
- **MazeAgent** — Now has a CharacterSheet, health tracking, death state
- **Room** — Can now hold a MonsterEncounter
- **AutonomousAgentBrain** — Agents now peek at threats and retreat strategically

### Documentation (5 comprehensive guides)
- `README.md` — Full architecture and feature overview
- `QUICK_START.md` — 5-minute setup guide
- `ARCHITECTURE.md` — Class diagrams and data flow
- `INTEGRATION_EXAMPLE.md` — Copy-paste integration code
- `IMPLEMENTATION_CHECKLIST.md` — What's done, what's next
- `COPY_PASTE_EXAMPLES.cs` — Code templates

## Quick Start (Get It Running in 15 min)

### 1. Create Monster Assets
In Unity editor:
- Right-click Project > Create > Monster
- Name: "Goblin"
- Set Max Health: 15, Speed: 8, Attack: 4, Defense: 1
- Save to `Assets/Resources/Monsters/Goblin.asset`

### 2. Create Equipment
- Create > Weapon
  - Name: "Iron Sword"
  - Attack Bonus: 5
  - Save to `Assets/Resources/Items/Weapons/IronSword.asset`
- Create > Armor
  - Name: "Leather Armor"
  - Defense Bonus: 3
  - Save to `Assets/Resources/Items/Armor/LeatherArmor.asset`

### 3. Update MazeSceneBuilder
```csharp
private Monster[] _monsterPool;
private Weapon[] _startingWeapons;
private Armor[] _startingArmor;

private void Start()
{
    _monsterPool = Resources.LoadAll<Monster>("Monsters/");
    _startingWeapons = Resources.LoadAll<Weapon>("Items/Weapons/");
    _startingArmor = Resources.LoadAll<Armor>("Items/Armor/");
    
    // ... rest of your code ...
}

private void SpawnAgent(int index, Room startRoom)
{
    // Create character sheet with equipment
    var stats = new CharacterStats();
    var sheet = new CharacterSheet(stats);
    
    if (_startingWeapons.Length > 0)
        sheet.EquipWeapon(_startingWeapons[Random.Range(0, _startingWeapons.Length)]);
    if (_startingArmor.Length > 0)
        sheet.EquipArmor(_startingArmor[Random.Range(0, _startingArmor.Length)]);
    
    // Create agent with sheet
    var agent = new MazeAgent($"Agent_{index}", startRoom, sheet);
    
    // ... rest of agent setup ...
    
    brain.Initialize(
        controller,
        generator,
        initialDelay + index * 0.2f,
        decisionInterval,
        exploreChance,
        1.5f,  // retreatThreshold - new parameter!
        () => IsLevelEnded()
    );
}
```

### 4. Update MazeGenerator
In `BuildRoom()` or similar:
```csharp
private void SpawnEncounter(Room room)
{
    if (room.Kind == RoomKind.Start || room.Kind == RoomKind.Exit)
        return;  // Don't spawn in start/exit rooms
        
    if (_monsterPool == null || _monsterPool.Length == 0)
        return;
        
    if (Random.value > 0.7f)  // 70% chance
        return;
    
    var encounter = new MonsterEncounter();
    encounter.SpawnMonsters(_monsterPool, 1, 3);  // 1-3 monsters
    room.Encounter = encounter;
}
```

### 5. Test
- Play in Unity
- Agents should spawn with equipment
- Open a room with a Goblin - agent's brain will peek and decide whether to enter
- If you've wired combat, fight should trigger

## Key Features Included

### ✅ Character System
- Agents and monsters both have stats (health, speed, attack, defense, magic)
- Effective stats calculated with equipment bonuses
- Support for temporary buffs/debuffs
- Health tracking and death state

### ✅ Equipment System
- Weapons: boost attack (+ optional secondary effects)
- Armor: boost defense (with penalties like slowness)
- Automatic stat bonus application when equipped
- Extensible for new item types (rings, accessories, etc.)

### ✅ Monster System
- ScriptableObject templates for each monster type
- Loot tables (items that drop when defeated)
- Starting equipment (weapons/armor monsters carry)
- Color-coded for visualization

### ✅ Encounter System
- Rooms can have monster encounters
- Encounters track alive/defeated monsters
- **Incomplete information**: agents see 60-100% of actual monsters (don't know the real count)
- Challenge rating calculation (perceived vs actual)

### ✅ Agent Intelligence
- **Peek mechanic**: agents look into rooms before entering
- **Threat evaluation**: calculate danger level before committing
- **Retreat logic**: avoid dangerous exits if safer options exist
- Uses challenge rating to make decisions
- Falls back to exploration if cornered

## What Still Needs Implementation

### Priority 1: Combat Resolution
The `CombatResolver` is a skeleton. You'll add:
1. Turn order (based on Speed stat)
2. Attack resolution (attack vs defense damage)
3. Multiple rounds until victory/defeat
4. Loot distribution when agent wins

### Priority 2: MazeAgentController Integration
Add combat triggering:
1. Detect agent entering a room with living monsters
2. Call CombatResolver
3. Handle victory (reward, continue) or defeat (agent dies, stops moving)

### Priority 3: UI & Feedback
- Health bars for agent + monsters
- Combat log showing what happened each turn
- Equipment/inventory screens
- Audio cues for hits, misses, victories

### Priority 4: Monster AI
- Decide which agent to target
- Choose between attack/defend/ability
- Retreat when badly wounded

### Priority 5: Advanced Features
- Special abilities (spells, tactics)
- Status effects (poison, stun, buffs)
- Difficulty scaling by room depth
- Boss encounters with unique abilities

## Architecture Overview

```
Agent → CharacterSheet → [Equipment Bonuses] → Effective Stats
                             ↑
                        Weapon/Armor
                        (apply modifiers)

Room → MonsterEncounter → [Monster Instances] → Combat when Agent enters
                             ↑
                          Monster Template
                          (loot table, AI)

AutonomousAgentBrain → Peek at adjacent rooms
                    → Get perceived threat (60-100% of actual)
                    → Compare to retreat threshold
                    → Choose safe exit or fight
```

## Next Steps

1. **Read `QUICK_START.md`** — Copy-paste your first setup
2. **Create test assets** — One weapon, armor, monster (5 min)
3. **Wire up MazeSceneBuilder** — Load resources and create agents with equipment (5 min)
4. **Add encounter spawning** — Monsters appear in rooms (5 min)
5. **Implement basic combat** — Fill in CombatResolver.cs (30 min+)
6. **Integrate into MazeAgentController** — Trigger combat when agent enters room (10 min)
7. **Test and iterate** — Tweak numbers, add features

See `INTEGRATION_EXAMPLE.md` for detailed copy-paste code for each step.

## Tips & Best Practices

✅ **Do:**
- Create assets in the editor (Create > Monster/Weapon/Armor) — it's easier
- Start with simple monsters (low stats, no special abilities)
- Test with 2-3 agents first before ramping up to 10+
- Save weapon/armor/monster assets to `Resources/` for easy loading
- Use different colors for different monster types (helps visualize)
- Add Debug.Log statements in CombatResolver to see what's happening

❌ **Don't:**
- Try to implement full combat AI before basic damage works
- Create hundreds of asset variants right away — start simple
- Forget to handle dead agents (they should stop moving)
- Assume balanced numbers first time — you'll need to tweak
- Implement every feature at once — do it incrementally

## Questions?

- **How do agents pick loot?** — Implement in CombatResolver.AwardLoot() — currently just a stub
- **How do monsters decide targets?** — Implement in CombatResolver.ExecuteMonsterTurn() — currently just attacks
- **Can I scale difficulty?** — Yes! Modify monster stats by room depth in the spawning code
- **Can multiple agents fight together?** — Architecture supports it, but combat resolve is 1v1 currently
- **How do special abilities work?** — Not yet implemented, but CharacterSheet supports temporary bonuses as a foundation

## You Got This! 🎮

You have all the pieces. Now implement the combat logic and watch your agents fight their way through the maze!

Start with `Assets/Scripts/Maze/Combat/QUICK_START.md` → then `INTEGRATION_EXAMPLE.md` → then fill in `CombatResolver.cs`.

Good luck! 🚀
