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 objects


Let's add in the display objects the player will see while in gameplay.

  1. After the loadGame() function, we're going to create another function that will display all our game objects on screen. The following lines will display the art assets that were created for this tutorial:

    function addGameScreen()
    
      background = display.newImage("bg.png", 0, 0, true )
      background.x = _W 
      background.y = _H
      
      paddle = display.newImage("paddle.png")
      paddle.x = 240; paddle.y = 300
      paddle.name = "paddle"
      
      ball = display.newImage("ball.png")
      ball.x = 240; ball.y = 290
      ball.name = "ball"
  2. Next, we'll add in the text that will display the score and level number during the game.

      scoreText = display.newText("Score:", 5, 2, "Arial", 14)
      scoreText:setTextColor(255, 255, 255, 255)
      
      scoreNum = display.newText("0", 54, 2, "Arial", 14)
      scoreNum:setTextColor(255, 255, 255, 255)
      
      levelText = display.newText("Level:", 420, 2, "Arial", 14)
      levelText:setTextColor...
