# Building from Source

To download the latest available release, clone this repository over github.

```console
    $ git clone https://git.nj3.xyz/blockgame_linux
```

Then compile from source via cmake after moving into the blockgame_linux directory.
```console
    $ cd ./blockgame_linux
    $ cmake ./
    $ make
```

# Client Usage

Simply executing the binary will start a background server and connect your client to it.
```console
    $ ./blockgame_linux
```
Others may connect, provided they provide your IP address as an address argument.
```console
    $ ./blockgame_linux --address <your.ip.address.here>
```
Other arguments can be found with the help argument.
```console
    $ ./blockgame_linux --help
```

# Server Usage
A dockerfile has been provided and launching the server may be achieved with the
following helper script:
```console
    $ ./run_server.sh
```
We suggest you open the server's port (8191 by default) if necessary.
