Overview of this book

With its powerful tools and quick implementation capabilities, Flutter provides a new way to build scalable cross-platform apps. In this book, you'll learn how to build on your knowledge and use Flutter as the foundation for creating games. This game development book takes a hands-on approach to building a complete game from scratch. You'll see how to get started with the Flame library and build a simple animated example to test Flame. You'll then discover how to organize and load images and audio in your Flutter game. As you advance, you'll gain insights into the game loop and set it up for fast and efficient processing. The book also guides you in using Tiled to create maps, add sprites to the maps that the player can interact with, and see how to use tilemap collision to create paths for a player to walk on. Finally, you'll learn how to make enemies more intelligent with artificial intelligence (AI). By the end of the book, you'll have gained the confidence to build fun multiplatform games with Flutter.

Playing sound effects

As mentioned in the previous section, when playing sound effects, we need to handle the pausing and resuming of the sound effects if they are still playing when the app is put in the background, for instance, to check something else on your phone, as this is not currently handled by the library.

We will initially update our Character class, which is our top-level base class for all our sprites, to add onPaused and onResumed callbacks, which all our sprites can use.

We will then listen for life cycle change events in our game and if these are called, we will iterate over all our sprites and pass on these events.

And finally, as the sound effects are related to George, we will update the George class to play sounds and pause and resume these sound effects when needed. Let's get started:

  1. Open up the character.dart file. At the bottom of the Character class, add the following function definitions:
    void onPaused() {}
    void onResumed() {}
...
