⚡ POWER GRID SYSTEM - Električna Omrežja

Design Concept
Datum: 10. Februar 2026

🎯 KONCEPT:

Player lahko gradi električno omrežje (power grid) po otoku!

Generator → [Kabel] → Električni Drog 1 → [Kabel] → Drog 2 → [Kabel] → Farma

🔌 KAKO DELUJE:

1. BUILD POWER POLE (Električni Drog)

Crafting:

Wood × 10 (pole material)
Wire × 5 (connections)
Nails × 3 (assembly)

Mehanika:

Postaviš kjer hočeš (click to place)
Range: 10 tiles (max distance do naslednjega droga)
Height: 2 tiles (visual tall pole)

2. AUTO-CONNECT CABLES

Cable Drawing:

Ko postaviš Power Pole, se avtomatsko poveže z najbližjim:
- Generator (source)
- Drugim Power Pole (chain)

Vizualizacija:

Uporabi objekt_cevi_in_kabli_set.png
Draw line (cable) med connected poles
Animated spark effect (power flow)

Range Rules:

Max 10 tiles med dvema drogoma
Če je predaleč → ❌ "TOO FAR - Need another pole"
Če je prenizko → ⚠️ "Low voltage warning"

3. POWER BUILDINGS

Powered Structures:

A) Generator (Source):

Produces power (bio-oil fuel)
Output: Unlimited range to first pole
Visual: Green light when ON

B) Power Poles (Relays):

Extend power range
Chain: Pole → Pole → Pole (unlimited chain)
Visual: Small spark at top when powered

C) Buildings (Consumers):

Powered zgradbe:

Rudnik (Mine) - Deep mining enabled
Rastlinjak (Greenhouse) - Climate control (faster growth!)
Cold Storage - Food preservation
Workshop (Delavnica) - Power tools (faster crafting)
Water Pump - Auto-irrigation system
Electric Fence - Auto-shock zombies

Power Required:

Manjši buildings: 1 unit
Večji buildings: 3 units
Generator capacity: 10 units total

🎮 GAMEPLAY MECHANICS:

Phase 1: Basic Grid

Player Actions:
1. Build Generator near base
2. Craft Power Pole × 3
3. Place poles forming path to Greenhouse
4. Cables auto-connect (visual line)
5. Greenhouse now "Powered" (green icon)
6. Growth speed +50%!

Phase 2: Expansion

Player expands grid:
- Generator → Pole 1 → Pole 2 → Farm Area
                    ↘ Pole 3 → Mine
                              
All connected buildings get power!

Phase 3: Management

Power Management:
- Generator capacity: 10 units
- Currently used: 7 units
  - Mine: 3
  - Greenhouse: 2
  - Workshop: 2
- Available: 3 units (can add more buildings)

📊 VISUAL DESIGN:

Cable Rendering:

Option A: Simple Lines (Easy)

// Draw straight line between poles
graphics.lineStyle(2, 0x555555, 0.8);
graphics.lineBetween(pole1.x, pole1.y, pole2.x, pole2.y);

Option B: Hanging Cables (Realistic)

// Curved line (sag effect)
graphics.lineStyle(2, 0x333333, 0.8);
// Bezier curve with slight droop
const midY = (pole1.y + pole2.y) / 2 + 20; // Sag
graphics.curve(pole1.x, pole1.y, midX, midY, pole2.x, pole2.y);

Option C: Tileset Cables (High Quality)

Use objekt_cevi_in_kabli_set.png sprites
Place segments between poles
Animated spark particles

Visual Feedback:

Power Status Colors:

🟢 Green: Powered (working)
🟡 Yellow: Low power (capacity warning)
🔴 Red: No power (disconnected)
⚪ Gray: Not connected

Particle Effects:

⚡ Small sparks travel along cables
💡 Buildings glow when powered
🔥 Generator emits smoke (when ON)

🛠️ IMPLEMENTATION:

Step 1: Power Pole Building

// In GrassScene
createPowerPole(x, y) {
    const pole = this.add.sprite(x, y, 'objekt_elektricni_drog');
    pole.setOrigin(0.5, 1.0); // Bottom anchor
    pole.setDepth(y);
    
    // Physics
    this.physics.add.existing(pole, true);
    
    // Power data
    pole.isPowered = false;
    pole.connectedTo = null; // Linked pole
    
    this.powerPoles.push(pole);
    this.connectNearestPole(pole);
}

Step 2: Auto-Connection

connectNearestPole(newPole) {
    let nearest = null;
    let minDist = Infinity;
    
    // Find nearest powered pole or generator
    this.powerPoles.forEach(pole => {
        if (!pole.isPowered) return;
        const dist = Phaser.Math.Distance.Between(
            newPole.x, newPole.y, pole.x, pole.y
        );
        
        if (dist < minDist && dist <= MAX_CABLE_RANGE) {
            minDist = dist;
            nearest = pole;
        }
    });
    
    if (nearest) {
        newPole.connectedTo = nearest;
        newPole.isPowered = true;
        this.drawCable(newPole, nearest);
    }
}

Step 3: Cable Drawing

drawCable(pole1, pole2) {
    const cable = this.add.graphics();
    
    // Hanging cable effect
    cable.lineStyle(3, 0x333333, 0.7);
    cable.beginPath();
    cable.moveTo(pole1.x, pole1.y - 100); // Top of pole
    
    // Bezier curve (sag)
    const midX = (pole1.x + pole2.x) / 2;
    const midY = (pole1.y + pole2.y) / 2 + 30; // Droop
    cable.quadraticCurveTo(
        midX, midY,
        pole2.x, pole2.y - 100
    );
    
    cable.strokePath();
    cable.setDepth(-10); // Behind objects
    
    this.cables.push(cable);
}

Step 4: Power Buildings

checkBuildingPower(building) {
    // Check if any power pole is in range
    this.powerPoles.forEach(pole => {
        if (!pole.isPowered) return;
        
        const dist = Phaser.Math.Distance.Between(
            building.x, building.y, pole.x, pole.y
        );
        
        if (dist <= POWER_RADIUS) {
            building.isPowered = true;
            building.setTint(0x88ff88); // Green glow
        }
    });
}

🎯 GAMEPLAY BENEFITS:

Strategic Depth:

Plan pole placement (optimize routes)
Balance cost vs. coverage
Expand grid as island grows

Visual Appeal:

See power flow (cables, sparks)
Satisfying build progression
Clear infrastructure visualization

Resource Management:

Generator needs bio-oil (fuel)
Limited capacity (10 units)
Choose which buildings to power

💡 ADVANCED FEATURES (Future):

Faza 2+:

Upgrade System:
- Wood Pole → Steel Pole (longer range)
- Basic Generator → Industrial Generator (20 units)
Power Loss:
- Long cable runs = voltage drop
- Need transformer poles
Backup Power:
- Solar panels (day only)
- Battery storage (night backup)
Circuit Breaker:
- Overload protection
- Manual ON/OFF switches

✅ PRODUCTION PRIORITY:

3. Day 13: Place poles to Greenhouse (3 tiles apart)
4. Cables auto-draw (visual confirmation)
5. Greenhouse now Powered!
   - Growth speed +50%
   - Climate control ON
   - Can grow rare crops!
6. Day 20: Extend grid to Mine
