Corona SDK Mobile Game Development: Beginner's Guide

Overview of this book

Corona SDK is the fastest and easiest way to create commercially successful cross platform mobile games. Just ask Robert Nay, a 14 year old who created Bubble Ball - downloaded three million times, famously knocking Angry Birds off the top spot. You don't need to be a programming veteran to create games using Corona. Corona SDK is the number one tool for creating fun, simple blockbuster games. Assuming no experience at all with programming or game development you will learn the basic foundations of Lua and Corona right through to creating several monetized games deployable to Android and Apple stores. You will begin with a crash course in Lua, the programming language underpinning the Corona SDK tool. After downloading and installing Corona and writing some simple code you will dive straight into game development. You will start by creating a simple breakout game with controls optimized for mobile. You will build on this by creating two more games incorporating different features such as falling physics. The book ends with a tutorial on social network integration, implementing in app purchase and most important of all monetizing and shipping your game to the Android and App stores.

Performance tips


The following are some helpful notes when creating good quality audio for your games.

Pre-loading phase

It is best to pre-load all your files at the startup of your application. While loadStream() is generally fast, loadSound() may take awhile since it must load and decode the entire file the instant it needs to be used. Generally, you don't want to be calling loadSound() in the parts of your app where users expect it to be running smoothly when events occur, such as during gameplay.

audioPlayFrequency

In your config.lua file, you may specify a field called audioPlayFrequency.

application =
{
   content =
   {
     width = 320,
     height = 480,
     scale = "letterbox",
     audioPlayFrequency = 22050
   },
}

This tells the OpenAL system what sample rate to mix and playback at. For best results, set this no higher than you actually need. So if you never need better than 22050 Hz playback, set this to 22050. It produces quality speech recordings or middle-quality recordings of...
