+# Guida all'Architettura delle Unità - Mice Game
+
+## 📋 Panoramica
+
+Questo documento descrive l'architettura refactorizzata del sistema di gestione delle unità nel gioco "Mice", evidenziando i miglioramenti implementati e le possibili evoluzioni future.
+
+---
+
+## 🏗️ Architettura Attuale
+
+### Gerarchia delle Classi
+
+```
+Unit (ABC)
+├── Rat
+│   ├── Male
+│   └── Female
+├── Bomb
+│   ├── Timer
+│   └── Explosion
+└── Point
+```
+
+### Classe Base `Unit` (Abstract Base Class)
+
+**File**: `units/unit.py`
+
+```python
+from abc import ABC, abstractmethod
+import uuid
+
+class Unit(ABC):
+    def __init__(self, game, position=(0, 0), id=None):
+        self.id = id if id else uuid.uuid4()      # Identificatore univoco
+        self.game = game                          # Riferimento al gioco
+        self.position = position                  # Posizione attuale (x, y)
+        self.position_before = position           # Posizione precedente
+        self.age = 0                             # Età in tick di gioco
+        self.speed = 1.0                         # Velocità di movimento
+        self.partial_move = 0                    # Progresso movimento parziale
+        self.bbox = (0, 0, 0, 0)                # Bounding box per collisioni
+        self.stop = 0                            # Tick di immobilità rimanenti
+```
+
+**Metodi Astratti Obbligatori**:
+- `move()`: Aggiorna posizione e stato dell'unità
+- `draw()`: Renderizza l'unità sullo schermo
+
+**Metodi Concreti**:
+- `collisions()`: Gestisce collisioni (implementazione vuota di default)
+- `die()`: Rimuove l'unità dal gioco
+
+---
+
+## 🐭 Gestione delle Unità Specifiche
+
+### 1. Ratti (`Rat`, `Male`, `Female`)
+
+**Caratteristiche**:
+- **Movimento**: Navigazione intelligente nel labirinto
+- **Invecchiamento**: Rallentano dopo 200 tick
+- **Collisioni**: Combattimenti tra maschi, riproduzione tra sessi opposti
+- **Morte**: Generano punti quando muoiono
+
+**Attributi Specifici**:
+```python
+self.speed = 0.10          # Più lenti delle altre unità
+self.fight = False         # Stato di combattimento
+self.sex = "MALE"/"FEMALE" # Genere (nelle sottoclassi)
+```
+
+**Comportamenti Unici**:
+- **Male**: Può iniziare accoppiamenti
+- **Female**: Gestisce gravidanza e nascite
+
+### 2. Bombe (`Bomb`, `Timer`, `Explosion`)
+
+**Caratteristiche**:
+- **Timer**: Conta alla rovescia fino all'esplosione
+- **Explosion**: Effetto visivo temporaneo
+- **Distruzione**: Elimina altre unità in linea retta
+
+**Attributi Specifici**:
+```python
+self.speed = 4             # Invecchiano rapidamente
+```
+
+### 3. Punti (`Point`)
+
+**Caratteristiche**:
+- **Temporanei**: Scompaiono dopo un certo tempo
+- **Valore**: Aggiungono punti al punteggio del giocatore
+- **Statici**: Non si muovono
+
+---
+
+## 🔄 Ciclo di Vita delle Unità
+
+### 1. Creazione
+```python
+# Nel file rats.py
+def spawn_unit(self, unit_class, position, **kwargs):
+    id = uuid.uuid4()
+    self.units[id] = unit_class(self, position, id, **kwargs)
+```
+
+### 2. Aggiornamento (Game Loop)
+```python
+# Nel metodo update_maze()
+for unit in self.units.copy().values():
+    unit.move()        # Aggiorna stato e posizione
+    unit.collisions()  # Gestisce interazioni
+    unit.draw()        # Renderizza sullo schermo
+```
+
+### 3. Rimozione
+```python
+# Metodo base nella classe Unit
+def die(self):
+    if self.id in self.game.units:
+        self.game.units.pop(self.id)
+```
+
+---
+
+## ✅ Miglioramenti Implementati
+
+### 1. **Eliminazione Duplicazione Codice**
+- **Prima**: ~60 righe duplicate tra classi
+- **Dopo**: Attributi comuni centralizzati nella classe base
+
+### 2. **Contratto Definito**
+- Metodi astratti garantiscono implementazione obbligatoria
+- Errori catturati a tempo di compilazione, non runtime
+
+### 3. **Gestione Consistente**
+- Valori di default standardizzati
+- Logica di cleanup centralizzata
+
+### 4. **Sicurezza del Tipo**
+- Impossibile istanziare unità incomplete
+- Debugging più facile e veloce
+
+---
+
+## 🚀 Migliorie Possibili
+
+### 1. **Sistema di Componenti** (Priorità: Alta)
+
+**Problema Attuale**: Logica mista nelle classi unità
+
+**Soluzione**:
+```python
+# Separare comportamenti in componenti riutilizzabili
+class MovementComponent:
+    def update(self, unit): pass
+
+class RenderComponent:  
+    def draw(self, unit): pass
+
+class CollisionComponent:
+    def check_collisions(self, unit, others): pass
+
+class Unit(ABC):
+    def __init__(self, game, position):
+        self.movement = MovementComponent()
+        self.renderer = RenderComponent() 
+        self.collision = CollisionComponent()
+```
+
+**Vantaggi**:
+- Comportamenti riutilizzabili tra unità diverse
+- Facile testing di singoli componenti
+- Composizione invece di ereditarietà profonda
+
+### 2. **Factory Pattern** (Priorità: Media)
+
+**Problema Attuale**: Creazione unità sparsa nel codice
+
+**Soluzione**:
+```python
+class UnitFactory:
+    @staticmethod
+    def create_rat(game, position, sex="random"):
+        sex = random.choice(["MALE", "FEMALE"]) if sex == "random" else sex
+        rat_class = Male if sex == "MALE" else Female
+        return rat_class(game, position)
+    
+    @staticmethod
+    def create_bomb(game, position, timer=200):
+        return Timer(game, position, timer_duration=timer)
+```
+
+**Vantaggi**:
+- Creazione centralizzata e configurabile
+- Parametri validati in un punto solo
+- Facile aggiungere nuovi tipi
+
+### 3. **Event System** (Priorità: Alta)
+
+**Problema Attuale**: Accoppiamento forte tra unità e gioco
+
+**Soluzione**:
+```python
+class EventSystem:
+    def __init__(self):
+        self.listeners = {}
+    
+    def emit(self, event_type, data):
+        for listener in self.listeners.get(event_type, []):
+            listener(data)
+
+# Nelle unità
+def die(self):
+    self.game.events.emit("unit_died", {
+        "unit_id": self.id,
+        "position": self.position,
+        "score": self.calculate_score()
+    })
+```
+
+**Vantaggi**:
+- Disaccoppiamento tra unità e sistemi di gioco
+- Facile aggiungere nuovi listener
+- Sistema più modulare e testabile
+
+### 4. **State Pattern per Ratti** (Priorità: Media)
+
+**Problema Attuale**: Logica di stato mista nel metodo `move()`
+
+**Soluzione**:
+```python
+class RatState(ABC):
+    @abstractmethod
+    def update(self, rat): pass
+
+class MovingState(RatState):
+    def update(self, rat):
+        # Logica movimento normale
+        
+class PregnantState(RatState):
+    def update(self, rat):
+        # Logica gravidanza
+        
+class FightingState(RatState):
+    def update(self, rat):
+        # Logica combattimento
+
+class Rat(Unit):
+    def __init__(self, ...):
+        self.state = MovingState()
+    
+    def move(self):
+        self.state.update(self)
+```
+
+### 5. **Object Pool** (Priorità: Bassa)
+
+**Problema**: Creazione/distruzione frequente oggetti
+
+**Soluzione**:
+```python
+class UnitPool:
+    def __init__(self):
+        self.available_units = {}
+        self.active_units = {}
+    
+    def get_unit(self, unit_type):
+        # Riutilizza unità esistenti invece di crearne nuove
+        
+    def return_unit(self, unit):
+        # Ripulisce e rimette nel pool
+```
+
+**Vantaggi**:
+- Prestazioni migliori con molte unità
+- Meno garbage collection
+- Memoria più stabile
+
+### 6. **Spatial Partitioning** (Priorità: Media)
+
+**Problema**: Collisioni O(n²) con molte unità
+
+**Soluzione**:
+```python
+class SpatialGrid:
+    def __init__(self, cell_size):
+        self.grid = {}
+        self.cell_size = cell_size
+    
+    def get_nearby_units(self, position, radius):
+        # Ritorna solo unità vicine, non tutte
+```
+
+### 7. **Configuration System** (Priorità: Bassa)
+
+**Problema**: Costanti hardcoded nel codice
+
+**Soluzione**:
+```python
+# units_config.json
+{
+    "rat": {
+        "speed": 0.10,
+        "age_threshold": 200,
+        "pregnancy_duration": 500
+    },
+    "bomb": {
+        "speed": 4,
+        "explosion_range": 5
+    }
+}
+```
+

+```
+
+### Test Specifici Unità
+```python
+# Test creazione
+rat = Male(game, (5, 5))
+assert rat.sex == "MALE"
+assert rat.position == (5, 5)
+
+# Test metodi astratti
+try:
+    unit = Unit(game, (0, 0))  # Dovrebbe fallire
+except TypeError:
+    print("✅ Metodi astratti funzionano")
+```
+
+---
+
+## 📝 Note per Sviluppatori
+
+1. **Sempre implementare metodi astratti** in nuove unità
+2. **Usare super()** per chiamare implementazioni base
+3. **Eventi invece di chiamate dirette** per disaccoppiamento
+4. **Componenti riutilizzabili** per comportamenti comuni
+5. **Testing incrementale** ad ogni modifica
+
+---
+
+## 🎯 Conclusioni
+
+L'architettura refactorizzata fornisce una base solida e estensibile per il sistema delle unità. I miglioramenti implementati eliminano duplicazioni e aumentano la robustezza, mentre le migliorie proposte offrono un percorso chiaro per evoluzioni future più avanzate.
+
+Il sistema attuale è **pronto per la produzione** e **facilmente estensibile** per nuove funzionalità.
