Palette

Coloured with scandinavia-01 · SNÖ — first snowfall, frozen lake; the coolest white in the library. Reads as a Nordic naval chart: frosty body, deep-teal command rules, brick-red mine alerts.

Palette pulled from Rangrez, the global colour-palette library that backs all NakliTechie projects.


🤖 For Agents: Adding New Maps

Want to remix this game with new chokepoint maps? Here's how:

The Auto-Sampler Tool

Open auto-sampler.html in your browser. This tool:

  1. Loads the map at a specific lat/lng and zoom level using Leaflet + CartoDB tiles
  2. Locks the view to prevent scrolling/zooming
  3. Samples tile colors to detect water vs land:
    • Water = blue-dominant pixels (B > R + 15)
    • Land = cream/white pixels (high RGB, R ≥ B)
  4. Generates a 35×19 mask array where 0 = water, 1 = land
  5. Outputs the mask ready to paste into index.html

Adding a New Chokepoint

  1. Pick a location (e.g., Suez Canal, Panama Canal, Malacca Strait)
  2. Find coordinates that show the chokepoint clearly at zoom 8-9
  3. Edit auto-sampler.html:
    • Change center: [lat, lng] to your coordinates
    • Adjust zoom level (8-10 works best)
  4. Run the sampler:
    • Wait for tiles to load
    • Click "🔒 LOCK MAP"
    • Click "🤖 AUTO-DETECT WATER"
    • Adjust threshold if needed
    • Manually fix any errors by clicking cells
  5. Add to index.html:
    • Copy the generated mask
    • Add a new entry to the MAPS object with:
      • name: Display name
      • subtitle: Tagline for the map
      • center: [lat, lng] for the map view
      • zoom: Zoom level (8-10)
      • mask: Your sampled mask array
      • ticker: Region-specific news messages (8-12 items)
    • Add map-specific win/lose messages
  6. Add map selector option in the HTML dropdown

Example Coordinates

Chokepoint Coordinates Zoom Status
Strait of Hormuz [26.4, 56.5] 8 ✅ Added
Bab el-Mandeb [12.65, 43.35] 9 ✅ Added
Malacca Strait [2.5, 101.5] 8 ✅ Added
Taiwan Strait [24.3, 119.4] 8 ✅ Added
Suez Canal [30.0, 32.3] 9 Ready to add
Panama Canal [9.1, -79.6] 9 Ready to add
Bosphorus [41.1, 29.1] 10 Ready to add

Tips

  • Zoom level matters: Higher zoom = more detail, smaller coverage
  • Threshold adjustment: If auto-detect misses water, increase threshold; if it detects too much, decrease
  • Manual cleanup: Always review and click to fix stray cells
  • Test alignment: The grey overlay should match visible coastline
