Going the Distance with Babylon.js

By: Josh Elster

Overview of this book

Babylon.js allows anyone to effortlessly create and render 3D content in a web browser using the power of WebGL and JavaScript. 3D games and apps accessible via the web open numerous opportunities for both entertainment and profit. Developers working with Babylon.js will be able to put their knowledge to work with this guide to building a fully featured 3D game. The book provides a hands-on approach to implementation and associated methodologies that will have you up and running, and productive in no time. Complete with step-by-step explanations of essential concepts, practical examples, and links to fully working self-contained code snippets, you’ll start by learning about Babylon.js and the finished Space-Truckers game. You’ll also explore the development workflows involved in making the game. Focusing on a wide range of features in Babylon.js, you’ll iteratively add pieces of functionality and assets to the application being built. Once you’ve built out the basic game mechanics, you’ll learn how to bring the Space-Truckers environment to life with cut scenes, particle systems, animations, shadows, PBR materials, and more. By the end of this book, you’ll have learned how to structure your code, organize your workflow processes, and continuously deploy to a static website/PWA a game limited only by bandwidth and your imagination.

Integrating the Main Menu

Despite the potentially intimidating heading, there’s really not a whole lot we’ll need to do in order to incorporate all of the work from our snippets into the application’s code structure. In fact, after all of the effort and journeying we’ve done throughout this chapter, it may feel a bit anti-climactic when we finish this part of the work.

The most straightforward and simple way to do it is to copy and paste the whole of the MainMenuScene class from the snippet into your local file, making sure to entirely replace the existing class declaration. You’ll need to only slightly adjust your import statements; here are the two most relevant lines where this changes:

import { Scene, Vector3, Scalar, Observable, Sound, HemisphericLight } from "@babylonjs/core";
import { AdvancedDynamicTexture, Rectangle, Image, Button, Control, TextBlock, Grid, TextWrapping } from "@babylonjs/gui";
