<p>15-minute Santa is a game where you deliver presents across Seattle. You earn
|
|
more points delivering to high-density housing, and you need to refuel from
|
|
shops, so you'll have to understand where people live in relation to where they
|
|
work and shop.</p>

<h2><a class="header" href="#faq" id="faq">FAQ</a></h2>
|
|
<h3><a class="header" href="#why-did-yall-make-this" id="why-did-yall-make-this">Why did y'all make this?</a></h3>
|
|
<p>We normally work on <a href="https://abstreet.org">A/B Street</a>, a traffic simulation
|
|
that lets the general public explore a future prioritizing more sustainable
|
|
modes of transportation. All of the recent
|
|
<a href="https://crosscut.com/focus/2020/11/seattle-could-become-next-15-minute-city">talk</a>
|
|
about 15-minute cities prompted us to explore how Seattle's zoning causes many
|
|
people to live far from where they get groceries. After experimenting with a
|
|
<a href="fifteen_min.html">more serious</a> tool to understand walk-sheds, we decided to
|
|
spend a few weeks on something a bit more light-hearted.</p>
|
|
<h3><a class="header" href="#realism" id="realism">Realism</a></h3>
|
|
<p>The map of Seattle and location of shops comes from
|
|
<a href="https://www.openstreetmap.org/about">OpenStreetMap</a>. We only consider shops if
|
|
they sell food or drinks -- let us know if the map seems to be missing your
|
|
favorite restaurant. The number of housing units is based on
|
|
<a href="https://data-seattlecitygis.opendata.arcgis.com/datasets/current-land-use-zoning-detail">Seattle GIS data</a>.
|
|
Mixed-use buildings with both commercial and residential units aren't
|
|
represented. The game lets you upzone any house to place a new store; obviously
|
|
this is a vast simplification of how complex a real conversation about changing
|
|
zoning codes should be.</p>
|
|
<p>We rigorously evaluated the speed and carrying capacity of different cargo bikes
|
|
and sleighs on the market to tune the vehicles in the game.</p>
|
|
<h3><a class="header" href="#modding-the-game" id="modding-the-game">Modding the game</a></h3>
|
|
<p>Native versions only -- sorry, not easy to do on the web.</p>
|
|
<p>You can adjust the difficulty of the levels or give yourself all the upzoning
|
|
power you want by editing <code>data/player/santa.json</code>. You first have to set
|
|
<code>"enable_modding": true</code>. The format should mostly be self-explanatory; also see
|
|
<a href="https://github.com/dabreegster/abstreet/blob/be589f7ef4f649bb5a35bfe8de0bc81a9deeb029/santa/src/session.rs#L13">here</a>
|
|
as a reference. If you break something, just delete the file to start over. If
|
|
you come up with a better gameplay progression, please share -- tuning a game is
|
|
hard!</p>
|
|
<h3><a class="header" href="#adding-new-maps" id="adding-new-maps">Adding new maps</a></h3>
|
|
<p>Missing your slice of Seattle, or want to run somewhere else? If you have a bit
|
|
of technical experience,
|
|
<a href="https://dabreegster.github.io/abstreet/howto/new_city.html">follow this guide</a>
|
|
and then the above instructions for modding the game. Otherwise, draw the map
|
|
boundaries in <a href="http://geojson.io">http://geojson.io</a> and
|
|
<a href="https://github.com/dabreegster/abstreet/issues/new">send it to us</a> along with a
|
|
time limit, goal, and starting point on the map. If you have a public data
|
|
source for the number of housing units per building, please include it!</p>
