This repository contains our client for spe_ed, the game of the InformatiCup 2021. Our team placed third and won the award for the best github repository 🥳. A video about our solution is available here (German only)

In this README you find all the information you need to use our software. Navigate around with the table of contents. For more detailed information read the wiki or follow the links in the README. If you think some important information or feature is missing, feel free to open an issue. If you'd like to give us feedback directly feel free to mail us.

• Manual Installation
• Docker Installation
• Extensions

After completing this, you set up a spe_ed development server and you can run our client locally.

Our software is written in Go. So you need an up-to-date go installation. You can get information on how to install Go on your computer here. At least version 1.15 is required.

This program uses the websocket library that can be found here: https://github.com/gorilla/websocket.

After installing Go, you can run go get github.com/gorilla/websocket to install the library.

Run git clone https://github.com/TeamBrot/client.git to clone the repository.

Run cd client to jump right into it.

The client code is located in the client directory. Before building, go there by running cd client.

To build the code, run go build. In case of failure, check if you are in the right directory because the repository is also named client. If you change the code of the client make sure to run the build command.

To run the client you need a server, that implements the game API. If you got your own spe_ed server you can skip this step. Otherwise, you can use ours which we wrote for development purposes. You can find it here.

You can start the client by going into the client directory and then running ./client. Now the client tries to connect to our development server. If you get a connection established message you've succesfully setup our software 🥳

If you wish to connect to another server, set the URL environment variable accordingly. You find information about that here

./client runs the combi client. Other clients can be run with ./client -client <client>.

The following clients are available:

• basic
• minimax
• rollouts
• probability
• combi

To play on other servers, the environment variables URL, TIME_URL and KEY have to be set to the appropriate values.

For the official API of the competition, use these values:

URL="wss://msoll.de/spe_ed" TIME_URL="https://msoll.de/spe_ed_time" KEY="<key>"

If you connect the client to another server, you can watch the game in your browser under http://localhost:8081/

To build the docker image, run docker build . -t spe_ed.

To run the client container, run docker run -e URL="wss://msoll.de/spe_ed" -e TIME_URL="https://msoll.de/spe_ed_time" -e KEY="<key>" spe_ed.

We built several extensions for our spe_ed client. For example several scripts that can run or visualize games.

Run ./test_internal.sh to start mutltiple games. This can be useful to test different parameters or to run statistical analytics.

You can stop the script by creating a file with the name stop at the root of the repository.

Just change the script for your purposes.

You can also run ./test_api.sh to play multiple games on the official without having to restart the client manually.

The default client is the combi client. You can change that by setting the variable client directly in the script.

Prerequisites:

• Python 3.9+
• Pillow
• ffmpeg

Run ./visualize.py <path to JSON-Log> to create a video from a JSON-Log. You typically find all log files under client/log. To see all command line options run ./visualize.py --help.
