## Welcome to the ungleich-game, a geek game engine!

ungleich-game is supposed to be an easy-to-use, easy-to-play and
easy-to-extend game framework for geeks.

It features registration, challenges with dependencies and an easy
point system.

The project name is ungleich-game, as it has its roots at ungleich -
the project name might change later.

## How to play (in general)

* Select a game server
* Register
* List challenges - have fun!

### How to play (for instance on sxiii's laptop)
* Note: here HTTPie is used; can be replaced by curl or any other http tool
* Note2: example with localhost [::] is ipv6 localhost representation
* Note3: you can ran sample commands as-is in most cases, as they utilize your user name automatically

0. Try to access the game server without any argument
```
http [::]:5002
```

1. Register: send a POST request with your username
```
http POST [::]:5002/register user=$USER
```

2. Get challenges

```
http [::]:5002/challenge
```

3. Get a challenge description

```
http [::]:5002/challenge/RegisterNet
```

4. Solve a challenge

```
http POST [::]:5002/challenge/RegisterNet 'user=$USER' 'network=2a0a:e5c0:101::/64'
```

5. Get high score

```
http POST [::]:5002/points 'user=$USER'
```


## Overview - Game flow

* Users register at a game server
* Users play by getting challenges from the game server
* Users can see their or all high scores on the main page

## Overview - Development Flow

[not yet fully implemented]

The idea is that there are challenges and each challenge offers:

* A description
* Some dependencies (on something another challenge can provide)
* A score ("how difficult it is")

### How to add challenges

* Create challenges-<YOURNAME>.py and add challenges in there
* Do some magic so all challenges are imported by server

### How to run your own game server

Run
```
python server.py
```

### Testing game
If you want to automatically test the game server, run the ./test_game.sh script included in this directory.

## Overview - Security

None at the moment.


## Tech stack

The base for building games is:

* Python3 - The programmming language
* Flask   - web frontend
* etcd    - storing data, games, etcd.

## Requirements

Tested packages @ Ubuntu 18.04.3

* etcd3 (important, version 3)
* python3-etcd
* python3-flask
* python3-flask-restful

## Things to solve

* Enhance the Challenge class - maybe make it easier for challenges to abort
* Enhance the Challenge class - abstract away writing information?
* Implement dependencies / providers for challenges
* Add an easy to use CLI (Steven might like click)
* Write nice code to easily retrieve points per user
* Sort high score
* Maybe store all user information in one JSON object?
