The sprites module

The structure of the sprites module is formed by an array of sprites and several exported functions:

/*** src/sprites.js ***/

import sound from "react-native-sound";

const coinSound = new sound("coin.wav", sound.MAIN_BUNDLE);
let heightOfRockUp = 25;
let heightOfRockDown = 25;
let heightOfGap = 30;
let heightOfGround = 20;

export const sprites = [
   ...
];

function prepareNewRockSizes() {
  ...
}

function getRockProps(type) {
  ...
}

export function moveSprites(sprites, elapsedTime = 1000 / 60) {
  ...
}

export function bounceParrot(sprites) {
  ...
}

function hasCollided(mainSprite, sprite) {
  ...
}

export function checkForCollision(mainSprite, sprites) {
  ...
}

export function getUpdatedScore(sprites, score) {
  ...
}

This module begins by loading the sound effect we will play when the parrot passes a set of rocks to give feedback to the user about the increment in their score.

Then, we define some heights for several sprites:

• heightOfRockUp: This is the height...
