Corona App Development eBooks published by Burtons Media Group.
It was like herding cats. On one of the fore-mentioned projects, the app worked fine on the simulator, but crashed on the mobile device and was rejected by Apple. The experience was more than just a little frustrating and taught me a valuable lesson: If you are developing for a platform, have test devices! Android Corona only builds for Android OS 2.
Any devices that you plan to develop for must use the ARM V7 processor. It is recommended that you use the newer iOS on your devices.
To be able to deploy to an iOS device, you will need a Mac computer system and a Standard, Enterprise, or University developers account from Apple. Publishing Considerations I am sure that you are already envisioning how you will spend that first big check from your app sales.
But before you can sell your app, you will need to decide with whom you 3 will publish your app. There are several considerations specific to each publisher that you need to keep in mind. You will need to create an account with each vendor that you wish to sell through.
You do NOT have to sign up for any account until you are ready to begin selling your apps. Once you have your account setup you will need to decide if your app will be free or if you will charge for it.
In other words, if you charge 99 cents for an app, you will walk away with Programming in Corona: Lua In this text, the language that you will use throughout your programming experiences with Corona is Lua. It is free, distributed under the MIT license and widely used for level scripting in major games and is a natural fit to be used in mobile application development due to the small size of the interpreter.
If you have ever programmed or scripted in any modern programming language, you should find Lua to be easy to learn as we progress through the following lessons. I recommend one that allows the integration of Lua to make your editing easier.
Of course you can ignore all of these editors and use notepad or textedit if you so desire. I have been using BBEdit on my Mac for quite a while and it is my editor of choice when working on my Mac. BBEdit has built in configurations including Lua , which easily allows you to set the editor to the language you are developing in.
Outlaw has a built in editor. Coupled with its ability to greatly simplify tracking your Corona project, the cost of Outlaw is well worth it.

Outlaw is the primary tool that I use for my projects. Eclipse is the editor I use when working on my PC. Eclipse has a large community of support.
Corona Labs has created a plugin that simplifies many of the processes. Textmate is very popular in the Corona community with a Corona plugin available on the Corona Labs website. TextWrangler has the advantage of being a free editor for your Mac.
How to Make a Simple iOS and Android Game with Corona Tutorial
If you are used to developing using Objective-C, Xcode is a natural choice. When you open up your Corona SDK folder, you will find sample code, tools, a resource library as well as the Corona Terminal and Simulator the primary development tools that we will be using. This was easily corrected by downloading newer graphics card drivers to the system.
Corona SDK will run with older versions of OpenGL installed, as long as it is an application that is graphic intensive. You should be able to update your graphics card driver to correct the problem if it exists. This is a free download from the Oracle website. After you have downloaded the installer, follow the normal procedure to install the JDK to your system. Complete this one time authentication and you will be ready to go. Corona Developer Registration You should always launch the Corona Debugger on a Macintosh instead of the Simulator for performing application builds and testing.
On a Windows system, launching the Corona Simulator also launches the Corona Simulator Output window commonly referred to as the terminal window. The Corona Terminal gives you important feedback when you are building your apps and allows for easier troubleshooting. The Corona Terminal will automatically launch the Corona Simulator. Project 1. I downloadd the book or took the class because I wanted to program, not to go over some syllabus or a review of all the different ages of computer development.
Stop with the rolling of eyes! Before I lose you, let me guarantee that you will get a very valuable resource out of this Hello World project, something that you will use the rest of the time that you develop in Corona.
Was that enough to get your attention? This can be on your desktop or wherever you like to organize your work.
If there is no main. Save the main. Back in your editor type : print "Hello World" and save your file as main. If you are on a Microsoft Windows system, launch the Corona Simulator. On a Macintosh, launch Corona Terminal. On launch, you will see the Terminal window and the Welcome to Corona dialog box. Your initial window might be different based upon the version of Corona that you are using. For now select either iPhone or Droid and click on the Open button.
Selecting other devices could give you different results than what are in the screen shots that have been included. As soon as you open the project, the simulator will run the project. Did you notice? Look in the Terminal window. At the bottom you will see your Hello World displayed.
Hello World in the Corona Terminal window Congratulations! You just made your first Corona app! Now before you become disappointed, you just learned a very important tool for trouble shooting your applications.
Believe me when I tell you that this one command will save you hours of troubleshooting headaches! The first few lines provide information about the version of Corona and the location of the simulation files. Try newtext and look at the error that appears in the Terminal window. Save the file, and then launch your simulator.
You should now see Hello World displayed in the simulator. Hello World on the Droid simulator 12 What did you just do? We do not have to use the variable name textobj, we could use fred for the variable name but after a couple of days we might forget what fred represents. Use variable names that make sense. It might mean more typing, but you will really appreciate it when you go to revise or update the program at a later date.
We set textobj equal to the object that we create by calling display. The display. If you set this parameter to nil, it will default to the native.
I want to get you in the practice of setting the text color when you create a text object. Later we will look at how to fade the text object out or in. Get up to speed quickly with our chapter-by-chapter Getting started guide. Corona plugins give access to additional functionality and 3rd party services. This tutorial outlines the risk of global variables and provides a convenient method to eliminate them from your program. In game design, a common element is object spawning, whether it be spawning a variable number of enemies and placing them randomly about the screen, or spawning items repeatedly on a timer increment.
This tutorial covers the basics. In Lua, scope is a fundamental aspect of functional code. If you're new to Lua, please read onward to understand scope and learn some techniques for handling it properly. In this tutorial, discover some simple ways to make your code cleaner and more readable. Check out all tutorials. There are no restrictions on which stores you can build for.
Additionally, we offer a selection of plugins which allow you to easily extend the functionality of Corona; most of these are free, but some premium plugins must be downloadd. Finally, the Corona Marketplace offers over additional third-party plugins; many are free, while others are priced according to the vendors who maintain them. Enable drawing mode for testing, you can use "normal", "debug" or "hybrid" physics. Enable multitouch so more than 1 balloon can be touched at a time system.
Learn Corona Sdk Game Development Book
How many balloons do we start with? Is there any time left? Ready to play? This enables the detection of multiple touches at once, letting the user pop more than one balloon at a time in your game.
However, the Corona Simulator currently does not support multitouch. As every device will vary in size, it is easier to place objects on screen using relative placement versus absolute. This keeps track of the current number of balloons. You will start with 0 balloons and generate more balloons as the game loads. When the game is fully loaded, the game will start with balloons that the user has to pop in an allotted amount of time.
This is the amount of time that the player will have to pop as many balloons as possible. This will be the countdown time. Since the startTime will be constantly counting down each second, you will keep track of how much total time the player had to begin with.
The player will start with time remaining on the countdown time, so this variable is true when there is time left.
If the countdown reaches 0, the variable will be set to false. The game is not ready to play if the balloons are still loading, so this is initially set to false. When the balloons are finished loading, you set playerReady equal to true. You want the balloons to generate randomly along the x-axis, so you need a way to generate random values. When the app starts you will need to load the music avoid sound lagging.
A game is no fun without sound effects! So you load a sound effect here to play when the balloons are popped. Giving the Player Feedback When you save your changes to main. Time to create some text to give the player feedback! Add the following code below the variable section in main. Loading Balloons Then you set the text to scale evenly, regardless of the device. The reference point is at the bottom left hand corner of the object in question, relative to the coordinates that are used for that particular object.
In this case, when you specify coordinates for the screenText item, the bottom left of the item is placed at the specified coordinate point. For the x coordinate placement, you take the width of the screen, divide it in half and then move the text over pixels to the left. For the y coordinate, you take the height of the screen and move up 20 pixels up from the bottom.
Note: Corona coordinates start with 0,0 being the top left corner of the screen. The loading text should stay in approximately the same place for every device, and the app should look very similar regardless of the device selected. Change back to the iPhone view and add some code to main. BottomLeftReferencePoint ; timeText.
And of course, the text is placed at a different x coordinate, otherwise it would overlap the existing loading text. Save your main. Start the physics engine physics. Set gravity to be inverted physics.
Set the reference point to the center of the image myBalloon:setReferencePoint display. CenterReferencePoint ; -- 5. Generate balloons randomly on the X-coordinate myBalloon.
Generate balloons 10 pixels off screen on the Y-Coordinate myBalloon. Apply physics engine to the balloons, set density, friction, bounce and radius physics. Functions in Lua are similar to methods in Objective-C. A function can be called from your main code, and you can define a function at any place in your code. But you must first define the function before you can call it — so any code that calls the function must appear after the function itself!When the app starts you will need to load the music avoid sound lagging.
Suspense is Killing Me!
Buttons and Text Know your Boundaries Project 2: Add a scoring system where each balloon popped adds to the players score.
Corona currently allows the budding developer to publish to Android and iOS Apple devices, be it a smart phone or tablet. What just happened?
