Von Neumann Defense Force Build, Test, Release, Deploy

About

Von Neumann Defense Force is a game about spaceships. It is the continuation of an earlier project of the same name.

The project is in development, and might well stay there forever. As the next section details, a lot of things are in a rough state. Pull requests are still very welcome, however.

Status

This is a hobby project with no clear goal in mind. As such, I only work on whatever interests me, while leaving other things in half-done or broken states.

From a gameplay perspective, there's not a lot there. We have working multiplayer, and there are game mechanics, but they don't form a coherent whole.

From a technical perspective, the code is in a constant state of transition. Most of the gameplay code is basically an experiment in how to structure code such as this, so far without any satisfactory results. Little of that has been documented.

Instructions

Quickly testing the game

cargo run

This starts a test client with a built-in server. This is useful for quickly testing stuff, but it doesn't provide any multiplayer features.

Run the game with a local server

Start the local server:

cd vndf-server
cargo run

In another terminal, start a client to connect to that server:

cd vndf-launcher
cargo run -- --local

Using this technique, you can connect with any number of clients, until you run into scalability issues. As of this writing, games have been run with up to three clients.

Play the game on the official test server

cd vndf-launcher
cargo run

Please note that this will most likely result in a crash and a cryptic error message. If not, it might result in weird and unpredictable gameplay behavior.

The reason for that is, that only clients and servers running with the same version are compatible. No version check is implemented, so even if the protocol happens to be compatible, client and server might be running with different game code.

The official server is updated in a manual and haphazard manner, so you never quite know which version it is currently running.
