fragile.city

This is a zero-sum MMO. You get a township, and build a town to attract citizens — build schools, roads, transit systems, etc. Citizens will move to the best town for them — so you have to be competitive. However, the whole ecosystem shares one atmosphere — if everyone pollutes while building their towns, citizens become sicker and sicker, eventually die, and the game ends for everyone — you'll be presiding over a ghost town.

Running the game:

Make sure postgres is installed.

To start your Phoenix server:

mix setup

or

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Install Node.js dependencies with npm install inside the assets directory
  • this might not be a thing anymore

make sure Postgres is running, then start the Phoenix endpoint with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

Most of the important code is in lib

• mayor_game folder has the server stuff
  • auth has auth
  • city has modules for city stuff — buildables, citizens, details, town(cities)
    • town.ex has town town — it's the
    • buildable.ex has the multipliers for region-specific stuff
    • city_calculator.ex is how the city values are calculated each round
  • other files like city, repo are functions for DB calls / etc
• mayor_game_web has the live-view and web stuff

to add new buildables:

1. add in buildable.ex
2. mix ecto.reset
3. mix run priv/repo/seeds.exs

Ready to run in production? Check Phoenix deployment guides.

Deployment

The game can be deployed to fly.io via the auto-generated Dockerfile:

$ fly launch   # Opt-in to creating a Postgres database
$ fly deploy
$ fly open

To view production logs

$ fly logs

See: https://mayor.fly.dev

to reset the prod DB — iex in and run Ecto.Migrator.run(MyApp.Repo, :down, all: true), then redeploy

To IEX in to prod:

fly ssh console
app/bin/mayor_game remote
world = MayorGame.City.get_world(1)
MayorGame.City.update_world(world, %{pollution: 1000000})
city = MayorGame.City.get_town_by_title!("hi21")
city = MayorGame.City.get_town_by_title!("wat")
MayorGame.City.update_town(city, %{rock_yards: 10})
MayorGame.Auth.update_user(user, %{email_confirmation_token: "watsjjshjkfdjskal"})

To update all:
import Ecto.Query
from(t in MayorGame.City.OngoingAttacks)|> MayorGame.Repo.delete_all([])

from(t in MayorGame.City.Town, update: [set: [logs_deaths_housing: 0]])|> MayorGame.Repo.update_all([])
from(t in MayorGame.City.Town, where: t.treasury < 0, update: [set: [treasury: 0]])|> MayorGame.Repo.update_all([])

reset login dates for dev:
date = Date.utc_today()
from(t in MayorGame.City.Town, update: [set: [last_login: ^date]])|> MayorGame.Repo.update_all([])

from(u in MayorGame.Auth.User, where: u.id == 2115, update: [set: [unconfirmed_email: nil, confirmed_at: ]])|> MayorGame.Repo.update_all([])
from(u in MayorGame.Auth.User, where: u.id == 2115, update: [set: [is_alt: true]])|> MayorGame.Repo.update_all([])
from(u in MayorGame.Auth.User, update: [set: [is_alt: false]])|> MayorGame.Repo.update_all([])

alias MayorGame.City.Buildable
import Ecto.Query
for buildable <- MayorGame.City.Buildable.buildables_list() do
from(t in MayorGame.City.Town, where: field(t, ^buildable) < 0) |> MayorGame.Repo.update_all(set: [{buildable, 0}])
end

banning alts:
alt_ids = [MayorGame.City.get_town_by_title!("Apokalypse").user_id | alt_ids]
from(u in MayorGame.Auth.User, where: u.id in ^ alt_ids, update: [set: [is_alt: true]])|> MayorGame.Repo.update_all([])
