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 – pausing the game


It's more than just making a button, it's also pausing all the action onscreen, including physics and timers.

  1. Add in the variables local pauseBtn and local pauseBG where all the other variables are initialized near the beginning of the code. Preload the btnSound audio after gameOverSound near the top of the script.

    -- Place near other game variables
    local pauseBtn
    local pauseBG
    
    -- Place after gameOverSound
    local btnSound = audio.loadSound( "btnSound.wav" )
  2. Within the hud() function and after the scoreText chunk, create another function that will run the event for the pause button. Call the function onPauseTouch(event). Pause the physics in the game by setting gameIsActive to false and have the pause elements appear on screen.

        local onPauseTouch = function( event )
          if event.phase == "release" and pauseBtn.isActive then
            audio.play( btnSound )
            
            -- Pause the game
            
            if gameIsActive then
            
              gameIsActive...
