A casual game in Flutter intended as a web app, based on Flutter's Casual Game toolkit and Flame.

Steroids

This link launches a web app in your browser.

Launch the web app

Tap play, select a level, and fly your ship to collect minerals from asteroids. Use the arrow keys for movement:

• turn left (arrow up).
• turn right (arrow up).
• thrust (arrow up).
• Use the space bar to fire a dumb torpedo.
• Collect small blue asteroids by scooping them up.
• Blast larger asteroids into smaller ones. Avoid hitting larger asteroids as they damage your ship.
• Dock with the space station at the center to deposit your booty and get more ship power.
• Watch for powerups: power restore and fire faster.
• Watch out for Aliens and Pirates! Pirates take your booty. Aliens want to blow you out of space.
• Don't let your ship power fall to zero. You'll lose the level.

To run the app in debug mode:

flutter run

This assumes you have an Android emulator, iOS Simulator, or an attached physical device.

To run in a browser:

flutter run -d chrome

Code is organized in a loose and shallow feature-first fashion. In lib/src, you'll therefore find directories such as ads, audio or main_menu. The main game code is built with Flame, under game.

lib
├── src
│   ├── ads
│   ├── app_lifecycle
│   ├── audio
│   ├── crashlytics
│   ├── game_internals
│   ├── games_services

│   ├── main_menu
│   ├── play_session
│   ├── player_progress
│   ├── settings

├── ...
└── main.dart

The state management approach is intentionally low-level. That way, it's easy to take this project and run with it, without having to learn new paradigms, or having to remember to run flutter pub run build_runner watch.

Once a PR is merged to main, the web app will automatically build and deploy to the app link above. This repo uses the Git actions by bluefireteam
