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 – removing the bricks


When the ball collides with a brick, we will use the same technique applied to the paddle to determine the side the ball will follow. When a brick is hit, we'll need to figure out which brick has been touched and then remove it from both the stage and the bricks group. Each brick removal will increment 100 points to the score. The score will be taken from the score constant and added to the current score as text.

  1. Below the gameLevel2() function, create a function called removeBrick(event):

    function removeBrick(event)
  2. Check which side of the brick the ball hits using the if statement. When checking for an event, we'll be referring the event to the object name, "brick". This is the name we gave our brick display object:

      if event.other.name == "brick" and ball.x + ball.width * 0.5 < event.other.x + event.other.width * 0.5 then
            vx = -vx 
       elseif event.other.name == "brick" and ball.x + ball.width * 0.5 >= event.other.x + event.other.width ...
