What's new

~ BLOCKOPOLIS V1.4.0 CHANGELOG: ~

 

 

Settings and city name

  • New Blockopolis Settings screen, opened from the pause menu or the Mods list. You can rename the city (on servers, only operators can) and toggle music, traffic, animations, chirp sound, camera pan speed and disasters.

Land and world

  • The city area is now 512×512, split into 16 tiles. New cities own the middle 4 tiles. Buy Land costs $15k for the first tile, then $10k more for each one after.
  • The world now loads around where the camera is looking, not around your character.
  • Existing cities move to the centre of the new area automatically.

New city systems (older cities get about 30 game days to catch up)

  • Sewage: outlets ($600, must be by water, pollute) and treatment plants ($4,000).
  • Deathcare: cemeteries, crematoriums and hearses.
  • Abandonment: after about 10 days without services, or with high crime or unhappy residents. Buildings recover once the problem is fixed.
  • Education, Crime and Noise now affect land value, happiness and upgrades.
  • HUD: 17 info views, new Sewer and Rest lines, new advisor tips.

Industry

  • Industrial plots specialise by the land around them: forestry, farming, mining or fishing. A new Resources info view shows which you'd get.

Citizens and traffic

  • Pedestrians and cats have names. Inspecting a citizen shows their age, job, home, education and mood.
  • Vehicles drive the streets: cars, buses, trams, garbage trucks, delivery trucks, police, ambulances, and emergency responses.
  • Pedestrians cross only at zebra crossings, and vehicles stop for them.
  • Every vehicle has a more detailed model.

Roads and building

  • Streets are now 8 blocks wide and avenues 12, with kerbs, centre lines, zebra crossings and manholes.
  • New Cobblestone Lane and Tram Boulevard road styles. Bridges get stone arches.
  • Paint a Park lets you drag out a park from 3×3 to 40×40 at $3 per block.
  • Waterfront Harbor and Boardwalk.
  • Street furniture along sidewalks, plus custom designs you build in creative mode.
  • Animated buildings: wind turbines, cranes, roof fans, signs, treatment plant arms.

Disasters

  • Fires spread and can be saved by fire coverage. Storms knock out power. Floods hit whole waterfronts. Lost buildings leave rubble and get rebuilt.

Photo mode: H hides the UI, O circles the camera, F2 takes a screenshot. The camera can also tilt down to street level.

Mod compatibility: extra buildings when Create (Water Wheel Mill, Brass Works), Biomes O' Plenty (Botanical Garden) or Farmer's Delight (Farmers' Market) is installed. These fall back to vanilla blocks if the mod is removed.

Fixes: demand panel numbers no longer overflow, and boardwalks now count in building totals.
