Building Games with Flutter

By: Paul Teale

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.

Chapter 5: Moving the Graphics with Input

In this chapter, we will take control of our own character and move them around the screen with virtual joysticks and touch events, so the player can choose where they want to move their character.

We will start by looking at how to draw onscreen controls that behave like a thumb-stick on a PlayStation controller, with action buttons for things such as attacking and jumping. Next, we will connect the virtual controls with our George sprite and get him moving around the screen. And finally, we will discuss an alternative or addition to virtual controls, by controlling George with touch events, such as tapping on the screen and moving George to a tapped location.

So, we will cover the following topics:

  • Drawing onscreen controls
  • Moving our character with onscreen controls
  • Moving our character with touch
