## Set up dedicated screeps server.
# Tested only on Debian 8.6 x64 with 512mb.

## Dependencies
# To install steam, see https://wiki.debian.org/Steam
sudo apt-get install unzip git build-essential


## Setup node
# Probably not the simplest way but it works.
# Remove everything related to node, so that `node`, `nodejs`, `npm`, `n` or `node-gyp` is not found.
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash
sudo aptitude install -y nodejs
sudo npm install npm@latest -g
sudo npm install node-gyp@latest -g
node -v # v6.9.1
npm -v # 3.10.9
node-gyp -v # v3.4.0


## Create user who will run server
adduser screeps
sudo su screeps

# get ~/steamworks_sdk_137.zip from your steam developer account. It has to be v1.37!

## Set variables
STEAM_USER=
BETA_INVITE_CODE=


## Setup greenworks
cd ~
git clone https://github.com/greenheartgames/greenworks.git
cd greenworks/deps/
    unzip ~/steamworks_sdk_137.zip
    mv sdk steamworks_sdk
  cd ..
  npm install # if errors, do you have correct version of node and SDK?


## Setup steamcmd
wget http://media.steampowered.com/installer/steamcmd_linux.tar.gz
rm -rf steamcmd
mkdir ~/steamcmd
cd ~/steamcmd
  tar -xvzf ../steamcmd_linux.tar.gz


## Setup screeps for first time. It will ask password and always slows for 5-15min in the middle of download.
~/steamcmd/steamcmd.sh +force_install_dir ~/screeps +login $STEAM_USER +app_update 464350 -beta Server -betapassword $BETA_INVITE_CODE validate +exit


## Setup config: add steam_api_key from https://steamcommunity.com/dev/apikey
cd ~/screeps/server/
nano .screepsrc


## Setup launch scripts.
echo '#!/bin/bash
cd ~/steamcmd/
./steamcmd.sh +force_install_dir ~/screeps +login '$STEAM_USER' +app_update 464350 -beta Server -betapassword '$BETA_INVITE_CODE' validate +exit

## Start server!

update1: Raspbian doesnt support steam's architecture, retry with just debian.

backend/lib/game/server.js:

// try {
// if(!greenworks.isSteamRunning()) {
// throw new Error('Steam is not running');
// }
// if(!greenworks.initAPI()) {
// throw new Error('greenworks.initAPI() failure');
// }
// console.log("Connected to local Steam client, using native authentication");
// useNativeAuth = true;
// }
// catch(e) {
// console.log("Connecting to local Steam client failed:", e.message);

// Need these lines to use Steam Web API
 console.log("Using Steam Web API authentication instead");
 if (!process.env.STEAM_KEY) {
 throw new Error('STEAM_KEY environment variable is not set!');
 }
 useNativeAuth = false;
// }

backend/lib/game/api/auth.js:

if(request.body.useNativeAuth) {
 if(!useNativeAuth) {
 return q.reject('authentication method is not supported');
 }
 // Removed greenworks auth stuff... do we need to do something else?
 }

...but now all my rooms are red and I can't choose a spawn... possibly because I can't set a password?
