Simple OpenTTD GameScript HTTP Binding and Game Logger with a Flask Microservice.

Have you ever found OpenTTD's in-game stats to be insufficient and inaccessible? This piece of software aims to fix that. Stats are collected continuously, and saved to a database of your choice. Stats are are also accessible via HTTP endpoints.

Installation

Prerequisites

• OpenTTD + OpenTTD Source for your installed version
• ServerGS (internet-trains fork)
• A Python 3.7+ installation (for running Flask Service + Generating Bindings)
• (optional) A Database (supported)

Building ServerGS Bindings

• Edit gen_api_binding.py
  • Set openttd_path to your openttd path (/Users/ian/Downloads/OpenTTD-patches-jgrpp-0.34.3 for me)
  • Set gs_path to your gamescript folder path (src/script/api/game for me)
  • Set version to your version (string).
• Run gen_api_binding.py with your python installation.
• Copy the enclosing folder to your gamescript folder path.

Python Prerequisites

• Run python3 -m pip install -r requirements.txt

DB Setup

• Set your SQLALCHEMY_DATABASE_URI environment variable to your db's uri.
• Run the following commands.

export FLASK_APP=ottd.py

python3 -m flask db init
python3 -m flask db upgrade

Generate Doc

python3 -m ./gen_doc.py

Running

Optional, if you wish to use something other than an SqliteDb:

export DATABASE_URL=YOUR_DATABASE_URI

Then run

export FLASK_APP=ottd.py
export OTTD_GS_HOST=127.0.0.1
export OTTD_GS_PORT=3977
export OTTD_GS_PASSWORD=password 
python3 -m flask run -p 5000

Doc

Doc is hosted at http://localhost:5000/swagger-ui or http://localhost:5000/redoc when the server is running. api.json can also be used with other OpenAPI doc tools.
