React: Cross-Platform Application Development with React Native

By: Emilio Rodriguez Martinez

Overview of this book

React Native helps web and mobile developers to build cross-platform apps that perform at the same level as any other natively developed app. The range of apps that can be built using this library is huge. From e-commerce to games, React Native is a good fit for any mobile project due to its flexibility and extendable nature. This project-based book consists of four standalone projects. Each project will help you gain a sound understanding of the framework and build mobile apps with native user experience. Starting with a simple standalone car booking app, you will progressively move on to building advanced apps by adding connectivity with external APIs, using native features, such as the camera or microphone, in the mobile device, integrating with state management libraries such as Redux or MobX, or leveraging React Native’s performance by building a full-featured game. This book is ideal for developers who want to build amazing cross-platform apps with React Native. This book is embedded with useful assessments that will help you revise the concepts you have learned in this book. This book is repurposed for this specific learning experience from the content of Packt's React Native Blueprints by Emilio Rodriguez Martinez.

Overview


The game we will build in this lesson has simple mechanics:

  • The goal is to help a parrot fly between rocks in a cave

  • Tapping the screen will result in the parrot flying higher

  • Gravity will pull the parrot toward the ground

  • Any collision between the parrot and the rocks or the ground will result in the end of the game

  • The score will be increased every time the parrot flies through a group of rocks

This kind of game is very well suited to being built with React Native, as it doesn't really need complex animations or physics capabilities. All we need to be sure of is that we move every sprite (graphics component) on the screen at the correct time to create the feeling of continuous animation.

Let's take a look at the initial screen for our game:

This screen presents the logo and instructions about how to get the game started. In this case, a simple tap will start up the game mechanics causing the parrot to fly forward and up on every tap.

The player must help our parrot to fly through the rocks...
