Rise Together

A cooperative and competitive physics game. Keep the ball in the air by lifting the left and right sides of your paddle, climb through the levels, and race the other team to the top.

This is a hard fork from the RiseTogether research platform, the RiseTogether version is an experimental paradigm for researching group social dynamics. This version of the game is much more game-like and does not have all of the logging and multimodal integration that are used in the experiments.

• Solo: play offline and beat your best height.
• Online: team up (co-op) or play against another team (versus). Use quick match or a private room code. Players connect peer to peer, and the host player's device runs the physics.

Built with Flutter, Flame and Forge2D. It runs on Android, iOS, macOS, Windows, Linux and the web.

Play

• In the browser, online: https://rt-lobby.nexusdynamic.org
• In the browser, offline: https://nexusdynamic.github.io/RTGame/ (solo and the level editor; no server by default)
• Downloads for Windows, macOS, Linux and Android are on the releases page.
  • macOS: the app is not signed. The first time, right-click it and choose Open.
  • Linux: needs GTK 3, GStreamer and PulseAudio (or PipeWire's pulse server), which most desktops already have.
  • Android: use the APK for your device (arm64-v8a for most phones), or universal if unsure.

Using another server

Online play uses https://rt-lobby.nexusdynamic.org by default. To use another lobby server, including your own (see server/deploy/README.md), go to Settings → Online → Server. In a browser, the server must list the page's address in its ALLOWED_ORIGINS.

Development

flutter pub get
flutter run            # or: flutter run -d chrome
flutter test
flutter test integration_test/real_webrtc_test.dart -d linux   # real WebRTC
scripts/with-weston.sh flutter test integration_test/real_webrtc_test.dart -d linux   # same, headless (as CI)

Online play needs the lobby server (server/; deploying it, behind Caddy or an existing nginx, is in server/deploy/README.md). Builds use https://rt-lobby.nexusdynamic.org unless you pass --dart-define=LOBBY_URL=https://your.host, or --dart-define=LOBBY_URL=none for a build with no default server. For web builds, add --wasm --no-web-resources-cdn.

Releasing

1. Set version: in pubspec.yaml (e.g. 0.2.0+2; raise the +build number every release, because Android needs it to increase).
2. Commit, then tag and push: git tag v0.2.0 && git push origin v0.2.0.

The release workflow checks that the tag matches pubspec.yaml, runs CI, and builds every platform. It then creates a GitHub release, deploys the offline web build to GitHub Pages, and pushes the lobby image to ghcr.io/nexusdynamic/rtgame-lobby. A tag with a pre-release part (v0.2.0-beta.1) creates a pre-release and leaves Pages and latest alone. To try the builds without releasing, run the Build workflow by hand.

Android APKs are signed with the key in the ANDROID_KEYSTORE_BASE64, ANDROID_KEYSTORE_PASSWORD, ANDROID_KEY_ALIAS and ANDROID_KEY_PASSWORD secrets. Without those secrets they are signed with a debug key.
