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.

Creating shadows with layers

Layers are a feature of Flame that allow us to group things we want to draw together or draw a prerendered graphic that doesn't change much. In your game, you may have a background that you draw once from a combination of sprites or images, but then it is used as a static image that you use as a background and draw the other moving sprites on top.

It would be inefficient to keep creating this background if it isn't changing. So, you can create it once and store it as a layer, which you can draw before you render the other game graphics.

In Flame, there are two types of layers:

  • PreRenderedLayer – For static images
  • DynamicLayer – For things that are moving

PreRenderedLayer would be suitable for backgrounds due to its static nature.

You may also want to change something in the layer and regenerate the layer, and then cache the resulting image in the layer. For example, you may want to create a weather effect...
