# 🔧 ANTIGRAVITY NAMESPACE REFACTOR
**Unifying All Systems Under Single Namespace**

**Date:** 10.12.2025  
**Status:** 📋 PLANNED (Future)  
**Priority:** 🟢 LOW (Post-1.0)

---

## 🎯 **Goal:**

Poenotiti vse sisteme v enoten `Antigravity` namespace za:
- Better code organization
- Avoid global namespace pollution
- Easier debugging
- Clearer dependencies
- Professional code structure

---

## 📊 **Current State Analysis:**

### **Problem:**
Currently systems are scattered:
```javascript
// Global classes
class Player { }
class TerrainSystem { }
class FarmingSystem { }
class WeatherSystem { }
// ... 30+ more classes

// Global variables
let gameScene;
let uiScene;
let player;

// Mix of patterns
```

**Issues:**
- ❌ Global namespace pollution (40+ global classes)
- ❌ No clear structure
- ❌ Hard to track dependencies
- ❌ Potential naming conflicts
- ❌ Difficult to refactor

---

## ✅ **Proposed Structure:**

### **Antigravity Namespace:**

```javascript
const Antigravity = {
    // Core Engine
    Core: {
        Engine: { ... },
        GameLoop: { ... },
        EventBus: { ... },
        StateManager: { ... }
    },
    
    // Systems
    Systems: {
        Terrain: TerrainSystem,
        Farming: FarmingSystem,
        Weather: WeatherSystem,
        Inventory: InventorySystem,
        Combat: CombatSystem,
        Building: BuildingSystem,
        Quest: QuestSystem,
        Save: SaveSystem,
        Sound: SoundManager,
        Particle: ParticleEffects,
        // ... all 33 systems
    },
    
    // Entities
    Entities: {
        Player: Player,
        NPC: NPC,
        Zombie: Zombie,
        Boss: Boss,
        LootChest: LootChest,
        ZombieSpawner: ZombieSpawner
    },
    
    // Utilities
    Utils: {
        Isometric: IsometricUtils,
        PerlinNoise: PerlinNoise,
        Pathfinding: Pathfinding,
        SpatialGrid: SpatialGrid,
        ObjectPool: ObjectPool,
        Compression: Compression
    },
    
    // Data
    Data: {
        Items: ITEMS_DATA,
        Recipes: CRAFTING_RECIPES,
        NPCs: NPC_DATA,
        Quests: QUEST_DATA,
        Localization: TRANSLATIONS
    },
    
    // Constants
    Constants: {
        TILE_SIZE: 48,
        GRID_WIDTH: 100,
        GRID_HEIGHT: 100,
        PLAYER_SPEED: 200,
        // ... all constants
    }
};
```

---

## 🔄 **Migration Strategy:**

### **Phase 1: Create Namespace Structure**

**Step 1.1: Create Antigravity.js Core**
```javascript
// src/core/Antigravity.js
window.Antigravity = {
    version: '1.0.0',
    Core: {},
    Systems: {},
    Entities: {},
    Utils: {},
    Data: {},
    Constants: {}
};

// Helper methods
Antigravity.registerSystem = function(name, system) {
    this.Systems[name] = system;
    console.log(`✅ Registered system: ${name}`);
};

Antigravity.getSystem = function(name) {
    return this.Systems[name];
};
```

**Time:** 2 hours

---

### **Phase 2: Migrate Systems (33 files)**

**Example Migration:**

**Before:**
```javascript
// TerrainSystem.js
class TerrainSystem {
    constructor(scene) {
        this.scene = scene;
    }
}
```

**After:**
```javascript
// TerrainSystem.js
(function(Antigravity) {
    'use strict';
    
    class TerrainSystem {
        constructor(scene) {
            this.scene = scene;
        }
    }
    
    // Register to namespace
    Antigravity.Systems.Terrain = TerrainSystem;
    
})(window.Antigravity);
```

**Priority Order:**
1. Core systems (5 files) - 1 day
2. Game systems (15 files) - 2 days
3. Utility systems (8 files) - 1 day
4. Optional systems (5 files) - 1 day

**Total Time:** 5 days

---

### **Phase 3: Update Usage**

**Before:**
```javascript
// GameScene.js
this.terrainSystem = new TerrainSystem(this);
this.farmingSystem = new FarmingSystem(this);
```

**After:**
```javascript
// GameScene.js
this.terrainSystem = new Antigravity.Systems.Terrain(this);
this.farmingSystem = new Antigravity.Systems.Farming(this);

// Or with helper:
this.terrainSystem = Antigravity.createSystem('Terrain', this);
```

**Files to Update:**
- GameScene.js
- UIScene.js
- StoryScene.js
- Player.js
- All entity files

**Time:** 2 days

---

### **Phase 4: Migrate Constants**

**Before:**
```javascript
// Scattered across files
const TILE_SIZE = 48;
const GRID_WIDTH = 100;
```

**After:**
```javascript
// constants.js
Antigravity.Constants = {
    World: {
        TILE_SIZE: 48,
        GRID_WIDTH: 100,
        GRID_HEIGHT: 100
    },
    Player: {
        SPEED: 200,
        MAX_HEALTH: 100,
        MAX_ENERGY: 100
    },
    Game: {
        FPS_TARGET: 60,
        SAVE_INTERVAL: 300000 // 5 min
    }
};
```

**Time:** 1 day

---

### **Phase 5: Create Data Registry**

```javascript
Antigravity.Data = {
    Items: {
        get(id) {
            return ITEMS_DATA[id];
        },
        getAll() {
            return ITEMS_DATA;
        }
    },
    Recipes: {
        get(id) {
            return CRAFTING_RECIPES.find(r => r.id === id);
        },
        getCraftable(inventory) {
            // Logic to check craftable recipes
        }
    }
};
```

**Time:** 2 days

## 🔧 **Implementation Examples:**

### **System Registration:**

```javascript
// OLD WAY:
class FarmingSystem {
    // ...
}

// NEW WAY:
(function(AG) {
    class FarmingSystem {
        // ...
    }
    
    AG.registerSystem('Farming', FarmingSystem);
})(Antigravity);
```

### **System Usage:**

```javascript
// OLD WAY:
this.farmingSystem = new FarmingSystem(this);
this.farmingSystem.plantCrop(x, y, 'wheat');

// NEW WAY:
this.farming = new Antigravity.Systems.Farming(this);
this.farming.plantCrop(x, y, 'wheat');

// OR with factory:
this.farming = Antigravity.createSystem('Farming', this);
```

### **Accessing Data:**

```javascript
// OLD WAY:
const item = ITEMS_DATA['wheat'];
const recipe = CRAFTING_RECIPES.find(r => r.id === 'bread');

// NEW WAY:
const item = Antigravity.Data.Items.get('wheat');
const recipe = Antigravity.Data.Recipes.get('bread');
```

### **Using Constants:**

```javascript
// OLD WAY:
const speed = PLAYER_SPEED;
const size = TILE_SIZE;

// NEW WAY:
const speed = Antigravity.Constants.Player.SPEED;
const size = Antigravity.Constants.World.TILE_SIZE;
```

2. **API Reference** - Complete namespace documentation
3. **Examples** - Before/after comparisons
4. **Troubleshooting** - Common migration issues

---

## 🚀 **When to Do This:**

### **NOT NOW because:**
- ⏳ Still in active development
- ⏳ Beta release coming soon
- ⏳ Risk of breaking changes
- ⏳ Time better spent on features

### **DO AFTER:**
- ✅ 1.0 Release complete
- ✅ Game is stable
- ✅ Core features done
- ✅ Have 3-4 weeks for refactor

**Recommended Timeline:** Post-1.0 (January 2026)

## 💰 **Effort vs Value:**

### **Effort:** HIGH (3-4 weeks)
### **Value:** MEDIUM (Better code quality)

**Conclusion:** Good for long-term, not critical for Beta/1.0

**Status:** 📋 **Planned for Post-1.0**  
**Priority:** 🟢 LOW (Quality of Life)  
**Estimated Time:** 3-4 weeks
