Description
Book SynopsisReimagine your development process and create, test, and deploy your mobile, web, desktop, and embedded apps from a single codebase. This book shows you how to leverage Flame, the modular Flutter game engine, to build cross-platform 2D games.
With Flutter, you can create all kinds of apps by making subtle changes to projects at the code level. Guided by a practical project-based approach, you'll begin by downloading and installing the game engine. You'll then move on to creating widgets in Flutter and components within our game, such as player, enemy, background, consumables, etc. The book also shows you how to add sprites, render images, setup animation, and much more.
Flame Game Development is perfect for the novice eager to gain hands-on knowledge of this exciting game engine's library to create a simple 2D game.
What You'll Learn
- Apply Flutter coding skills to game development
- Develop games that can be played on all platforms
- Create your first 2D game using Flame
