bevy-steamworks

This crate provides a Bevy plugin for integrating with the Steamworks SDK.

Installation

Add the following to your Cargo.toml:

[dependencies]
bevy-steamworks = "0.7"

The steamworks crate comes bundled with the redistributable dynamic libraries of a compatible version of the SDK. Currently it's v153a.

Usage

To add the plugin to your app, simply add the SteamworksPlugin to your App. This will require the AppId provided to you by Valve for initialization.

use bevy::prelude::*;
use bevy_steamworks::*;

fn main() {
  // Use the demo Steam AppId for SpaceWar
  App::new()
      .add_plugins(DefaultPlugins)
      .add_plugin(SteamworksPlugin::new(AppId(480)))
      .run()
}

The plugin adds steamworks::Client as a Bevy ECS resource, which can be accessed like any other resource in Bevy. The client implements Send and Sync and can be used to make requests via the SDK from any of Bevy's threads. However, any asynchronous callbacks from Steam will only run on the main thread.

The plugin will automatically call SingleClient::run_callbacks on the Bevy main thread every frame in CoreStage::First, so there is no need to run it manually.

NOTE: If the plugin fails to initialize (i.e. Client::init() fails and returns an error, an error wil lbe logged (via bevy_log), but it will not panic. In this case, it may be necessary to use Option<Res<Client>> instead.

All callbacks are forwarded as Events and can be listened to in the a Bevy idiomatic way:

use bevy::prelude::*;
use bevy_steamworks::*;

fn steam_system(steam_client: Res<Client>) {
  for friend in steam_client.friends().get_friends(FriendFlags::IMMEDIATE) {
    println!("Friend: {:?} - {}({:?})", friend.id(), friend.name(), friend.state());
  }
}

fn main() {
  // Use the demo Steam AppId for SpaceWar
  App::new()
      .add_plugins(DefaultPlugins)
      .add_plugin(SteamworksPlugin::new(AppId(480)))
      .add_startup_system(steam_system)
      .run()
}
