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 4: Drawing and Animating Graphics

In this chapter, we will go beyond drawing simple shapes and discuss how to draw and animate pixel graphics seen in most games. This will make our game look much nicer and bring the game to life as the characters animate around the screen.

In game programming, a graphic or image that is drawn to the screen is known as a sprite, which can be anything from a single non-animated image, a player character with multiple frames of animation, or even the background image drawn behind other graphics on the screen.

We will start by showing how to load and draw a simple sprite instead of our square, and then animate the sprite to show movement. Next, we will move the sprite around the screen and the animation will change based on the direction the sprite is currently moving in.

And finally, we will create an enemy sprite for the player sprite to collide into as we build on our knowledge of collision detection.

So, we will cover the following...
