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 – launching the panda


Let's add a touch event for the panda so that it flings towards the stars. The powerShot object will play a role by helping the player visualize how much power is applied to the panda before it launches into the air.

  1. Implement touch events for the panda. Create a local function called onScreenTouch() with an event parameter.

    local onScreenTouch = function( event )
  2. With gameIsActive initiated, add in an if statement for when the touch event starts by using event.phase == "began". During this event, use the "crouch" animation set to prepare panda for launch.

      if gameIsActive then
        if event.phase == "began" and panda.inAir == false then
          
          panda.y = 225
          panda.isReady = true
          powerShot.isVisible = true
          powerShot.alpha = 0.75
          powerShot.x = panda.x; powerShot.y = panda.y
          powerShot.xScale = 0.1; powerShot.yScale = 0.1
          
          arrow.isVisible = true
          
          panda:prepare("crouch")
          panda:play()
  3. Add an elseif...
