Почему мой скрипт фазера не выводит карту, которую я создал?

Вот мой код: https://replit.com/@JackF99/test-2d-array (Ошибка в script.js)

Этот код должен вывести экран игры с картой.

let mapArr;
let drawX=0;
let drawY=0;
//map is declared as variable in map.js
class gameScene extends Phaser.Scene {
    //Constructor with config var declared at bottom
    constructor(config) {
        super(config);
    }
    //Preload aspects for gameScene 
    preload() {
        //Preloading images
        this.load.atlas("player", "assets/temp.png");
        this.load.image("spike", "assets/spike.png");

        this.load.image("floor", "assets/floor.png");
        this.load.image("wallLeft", "assets/wallLeft.png");
        this.load.image("wallRight", "assets/wallRight.png");
        this.load.image("WallBottom", "assets/wallBottom.png");
        this.load.image("wallTop", "assets/wallTop.png");
        this.load.image("bg", "assets/bg.png");
    }
    //Create function for gameScene
    create() {
        this.floor = this.physics.add.staticGroup();
        this.wallTop = this.physics.add.staticGroup();
        this.wallBottom = this.physics.add.staticGroup();
        this.wallLeft = this.physics.add.staticGroup();
        this.wallRight = this.physics.add.staticGroup();
        this.bg = this.physics.add.staticGroup();
        //Splitting the map string by into array variables
        let mapArr = map.split('.');
        //For each loop goes through each row of mapArr
        mapArr.forEach(row => {
            //Setting pixel value X to 0 when its a new row
            drawX = 0;
            //Goes through each variable in the row and creates image in its place
            for (let i = 0; i < row.length; i++) {
                if (row.charAt(i) === '7') {
                    this.floor.create(drawX, drawY, "floor");
                } else if (row.charAt(i) === '9') {
                    this.wallTop.create(drawX, drawY, "wallTop");
                } else if (row.charAt(i) === '8') {
                    this.wallBottom.create(drawX, drawY, "wallBottom");
                } else if (row.charAt(i) === '5') {
                    this.wallLeft.create(drawX, drawY, "wallLeft");
                } else if (row.charAt(i) === '6') {

}

Я хотел вывести рандомизированное подземелье, созданное в формате 2D-массива и возвращенное в виде строки. Я хотел вывести его в виде изображений на основе значений в строке.
