Building a Car Racing Game with React Native and Accelerometer Data

The Game Plan

In this tutorial, we’ll show you how to create a thrilling car racing game using React Native and harnessing the power of your phone’s accelerometer data. Our goal is to create a game where the user can steer their car sideways by tilting their device to the left or right.

Prerequisites

Before we start, make sure you have:

• A React Native development environment set up
• A phone with an accelerometer (most smartphones have one)
• Knowledge of JavaScript and React Native

App Overview

Our game will feature a car racing down a road, dodging opposing cars that are moving in the opposite direction. We’ll use the accelerometer data to detect the device’s tilt and move the car accordingly. The game will also feature a scoring system, where the user earns points for successfully evading opposing cars.

Setting Up the Project

To get started, create a new React Native project and install all the dependencies. You’ll also need to follow the installation instructions for React Native Sensors.

npx react-native init MyRacingGame
cd MyRacingGame
npm install react-native-sensors

Creating the App

Once you’ve set up the project, let’s dive into the code. We’ll create a World component that renders the game objects, including the car, road, and opposing cars. We’ll also use Matter.js to create the game physics and React Native Game Engine to render the game.

import React from 'eact';
import { View, Text } from 'eact-native';
import Matter from 'atter-js';
import { GameEngine } from 'eact-native-game-engine';

const World = () => {
  // Create game objects, including the car, road, and opposing cars
  // Set up game physics and collision detection
  // Render the game using React Native Game Engine
};

export default World;

The Magic Happens

In the World.js file, we’ll create the game objects, including the car, road, and opposing cars. We’ll use the accelerometer data to detect the device’s tilt and move the car accordingly. We’ll also set up the game physics, scoring system, and collision detection.

import { accelerometer } from 'eact-native-sensors';

const World = () => {
  const [accelerometerData, setAccelerometerData] = useState({});

  accelerometer.setUpdateInterval(100);
  accelerometer.addListener((data) => {
    setAccelerometerData(data);
  });

  // Use accelerometer data to move the car
  // Set up game physics and collision detection
  // Update the scoring system
};

The Final Lap

Once you’ve completed the tutorial, you’ll have a fully functional car racing game that uses the phone’s accelerometer data to move the car. You can view the app’s source code on our GitHub repo and start playing the game!
