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.

Memory management


It is important to call audio.dispose() on your loaded audio when you are completely done with the audio file. Doing so allows you to recover the memory.

audio.dispose()

Releases audio memory associated with the handle.

Syntax:

audio.dispose(audioHandle)

Parameters:

audioHandle - The handle returned by the audio.loadSound() or audio.loadStream() functions that you want to free.

Tip

You must not use the handle once the memory is freed. The audio should not be playing or paused on any channel when you try to free it.

Example:

mySound = audio.loadSound("sound1.wav")
myMusic = audio.loadStream("music.mp3")

audio.dispose(mySound)
audio.dispose(myMusic)

mySound = nil
myMusic = nil

Have a go hero – disposing audio

You have just learned how to dispose audio files properly to recover memory in your application. Try the following:

  1. Load your audio file and have it played over a set duration. Create a function that will dispose of the file when calling an onComplete command.

  2. In the Controlling...
