Hands-On Game Development with WebAssembly

By: Rick Battagline

Overview of this book

Within the next few years, WebAssembly will change the web as we know it. It promises a world where you can write an application for the web in any language, and compile it for native platforms as well as the web. This book is designed to introduce web developers and game developers to the world of WebAssembly by walking through the development of a retro arcade game. You will learn how to build a WebAssembly application using C++, Emscripten, JavaScript, WebGL, SDL, and HTML5. This book covers a lot of ground in both game development and web application development. When creating a game or application that targets WebAssembly, developers need to learn a plethora of skills and tools. This book is a sample platter of those tools and skills. It covers topics including Emscripten, C/C++, WebGL, OpenGL, JavaScript, HTML5, and CSS. The reader will also learn basic techniques for game development, including 2D sprite animation, particle systems, 2D camera design, sound effects, 2D game physics, user interface design, shaders, debugging, and optimization. By the end of the book, you will be able to create simple web games and web applications targeting WebAssembly.

Defining the CSS

Now that we have some basic HTML, we need to create a new shell.css file. Without any CSS styling, our page looks pretty terrible.

A page without styling will be similar to the one shown as follows:

Figure 2.1: The Hello WebAssembly app without a CSS style

Luckily for us, a little bit of CSS goes a long way to make our web page look presentable. Here is what the new shell.css file we are creating looks like:

body {
margin-top: 20px;
}

.input_box {
width: 20%;
display: inline-block;
}
.em_button {
width: 45%;
height: 40px;
background-color: orangered;
color: white;
border: 2px solid white;
font-size: 20px;
border-radius: 8px;
transition-duration: 0.5s;
}

.em_button:hover {
background-color: orange;
color: white;
border: 2px solid white;
}

.em_input {
width: 45%;
height: 20px;
font-size: 20px;
background-color: darkslategray...
