Building Games with Flutter

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.

Adding dynamic objects to the map

So far in the game, we have added a couple of each enemy, but now we are going to show you how enemies and other objects can be added dynamically to the game.

This is very common in games because you may want some treasure or an enemy to spawn at a certain location on the map. Tiled has a really great way to help us with this, with a feature called layers. The two most common layers are tile layers and object layers. We already used tile layers to display our map in the previous section, Loading a tile map. Object layers allow us to define objects that will be drawn on top of the map.

In the following screenshot, we show our tile map opened in Tiled, where you can see we have two layers named Enemies and Map. The Map layer is our tile layer, and the Enemies layer shows an object layer. We will use this Enemies layer to define spawn points for our enemies:
