# CHANGELOG - NovaFarma Development

## [Session: 10.12.2025] - CODE ORGANIZATION ✅ COMPLETE

### 📦 **CODE REFACTORING - Modular Architecture**

**Problem:** 
Koda je bila razpršena po različnih datotekah brez jasne strukture. Težko je bilo najti specifično logiko (npr. crafting recepti, zombie AI).

**Rešitev:**
Ustvarjena nova `src/core/` mapa z 6 moduli:

#### **Created Files (8):**
```
src/core/
├── main.js                    # Glavna zanka (Antigravity_Update) + konstante
├── player.js                  # Player gibanje, health, XP, level-up, combat
├── inventory_crafting.js      # Inventar + CRAFTING_RECIPES + zlato
├── world_interaction.js       # Drevo, kamen, zgradbe, farming, NPC
├── events_time.js             # LORE koledar, prazniki, developer birthdays
├── enemies.js                 # Zombie AI (idle/chase/attack), combat, loot
├── index.js                   # Centralni export vseh modulov
└── README.md                  # Dokumentacija strukture
```

#### **Vsebina Modulov:**

#### **Kako Uporabljati:**

**Način 1: Import iz posameznega modula**
```javascript
import { handlePlayerInput } from './core/player.js';
import { addToInventory } from './core/inventory_crafting.js';
```

**Način 2: Import iz index.js (priporočeno)**
```javascript
import { 
    handlePlayerInput, 
    addToInventory, 
    spawnZombie 
} from './core/index.js';
```

#### **Prednosti:**

✅ **Modularnost** - Vsak modul ima jasno definirano nalogo
✅ **Preberljivost** - Hitro najdeš kaj iščeš (npr. vse o zombijih v `enemies.js`)
✅ **Vzdrževanje** - Spremembe so izolirane (fix v `player.js` ne vpliva na `enemies.js`)
✅ **Testiranje** - Posamezne funkcije lahko testiraš neodvisno
✅ **Razširljivost** - Dodajanje novih funkcij je enostavno
✅ **Timsko delo** - Različni člani lahko delajo na različnih modulih brez konfliktov

#### **Dokumentacija:**

📄 `src/core/README.md` - Podrobna dokumentacija vseh modulov
📄 `PROJECT_STATUS.md` - Posodobljen z novo strukturo

### 🐛 KNOWN ISSUES & FIXES

**Fixed:**
1. ✅ CollectionSystem sound error (`playSuccess is not a function`)
2. ✅ NPC scale inconsistencies
3. ✅ Settings menu visibility
4. ✅ Language selector UI/UX

**Known Issues:**
1. ⚠️ NPC AI sprite transparency (checkerboard pattern) - Low priority
2. ⚠️ Steam integration requires Greenworks SDK for production

### 📋 NEXT STEPS

**Immediate (Ready to Implement):**
1. **Integration Testing** - Test all new systems together
2. **UI Polish** - Rustic/Post-apo theme for remaining UI
3. **Trailer Tools** - Smooth camera movement scripting
4. **Save/Load System** - Integrate with Steam cloud saves

**Future Features:**
1. **Seasonal Crops** - Extend perennial system to wheat/corn
2. **More Mounts** - Implement horse properly
3. **Achievement Triggers** - Wire up gameplay events to Steam achievements
4. **Volume Controls** - Implement sound settings UI

### 💡 DESIGN DECISIONS

1. **Localization Architecture:** Embedded translations vs external JSON files
   - Chose embedded for simplicity and instant loading
   - Can be externalized later if needed

2. **Mount System:** Inventory-based vs NPC-based
   - Chose NPC-based for better world interaction
   - Allows for mount status (health, stamina in future)

3. **Steam Integration:** Mock vs Direct SDK
   - Implemented mock system for development
   - Easy to swap to real Greenworks when publishing

4. **Main Menu:** Scrolling intro vs Static menu
   - Changed to static for better UX
   - Intro can be triggered separately (cutscene)
