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 10: Making Intelligent Enemies with AI

The game is coming along nicely now, but there isn't really any challenge to it yet. We collect the coins or kill our enemies, but that's all very predictable and easy.

In this chapter, we are going to change the game to make it more challenging by adding a health value to our player, George, and making the enemies chase us instead, reducing our health for each enemy that hits us. If our health gets to zero, we lose the game. So, the objective will be to collect the coins while avoiding the enemies.

To make the enemies appear more intelligent, we will use very simple Artificial Intelligence (AI) algorithms for the enemies to detect when George is nearby and, when they can see him, their movement will change from random movements to moving in George's direction to attack him.

We will then add some extra water to the map as obstacles and discuss how to move from your origin to the destination while avoiding the water...
