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.

Preface

Time for action – adding game listeners


For many of the functions we have created for our game objects we need to activate the event listeners so that they will run the code and disable them when gameplay has stopped.

  1. The last function we need to create in order to complete this game is called gameListeners(), which will also have a parameter called event. This should be added right after the gameLevel2() function.

    function gameListeners(event)
  2. Add in the following event listeners that will start several events in the application using an if statement:

      if event == "add" then
        Runtime:addEventListener("accelerometer", movePaddle)
        Runtime:addEventListener("enterFrame", updateBall)
        paddle:addEventListener("collision", bounce)
        ball:addEventListener("collision", removeBrick)
        paddle:addEventListener("touch", dragPaddle)
  3. Next we'll add in an elseif statement for the event listeners that will remove the events and then close the function.

      elseif event == "remove" then
        Runtime...
