Creating Projects
Assets (Building Blocks)
An app consists of several building blocks also known as the assets of the application:
- Source code: all code is written in the Lua scripting language. Most of the standard Lua library APIs are available for your use. In addition there are APIs offered by Ansca that allow you to quickly and easily create graphically rich and interactive applications. Your main Lua application code is executed from a file called
main.lua, but additional code may be placed in external Lua code files. - Non-code assets: usually these are multimedia assets such as image (e.g. PNG or JPEG) files, sound files, and video files that are referenced in your application code. You are free to use your favorite creative tools to create these assets.
Starting a Project
Creating projects is really simple. All you do is create an empty folder in which to put all asset files used by your application. This includes any external library files that you wish to reference from your main application file, main.lua .
It is important that you only put files that your application actually uses. You should not put older versions of your main.lua file or older versions of your multimedia assets. Also, you should only place final production assets in this folder; you should not place the original native files produced by creative tools like Photoshop® (PSD) or Illustrator® (AI).
If you were to create a project called "MyProject", the directory structure would look like:
MyProject/
Icon.png
logo.png
main.lua
library.lua
library2.lua
photo.jpg
...Notice that the code and non-code assets (e.g. images) are in the same directory. There’s also an icon image that lives alongside all the assets. This icon file should be a PNG that’s 57x57 pixels.
Note: Files that start with a . (period) are excluded from the application bundle during the build process and will not be included in the final application
For instructions on how to create your own external code libraries, see the Module section of the Api Reference. Additionally, for example code that loads optional Corona libraries, see the projects ButtonEvents and Movieclip in the Sample Code directory of the Corona SDK.

Are you kidding. I was working with the new windows beta and it is ticking me off, then to find out it will not do the I/stuff which is why I wanted it. I have a friend that will GIVE me what was the top of the line G5, but it will not support OS X 10.6, so here I am stuck again.

Hi,
I cannot build for iOS, Android or Xcode simulator. Is this a problem? Or in the trial version isn't permitted?
Thanks in advance.

EDIT- building under the trial version is supported, but only for your device. In order to do a 'proper' iOS build for deployment, Corona needs to be licensed.

hawkfire4 Thanks a bunch! I had quite coming in since it was driving me nuts. I broke down and purchased a macbook pro. Now I have the tools I need I just have to learn how to use everything. It is not that hard but definitely different.

How install TextWrangler_3.5.3.dmg in Windows XP? It's possible?
Thanks for advance!

Hi supercabb,
You won't be able to install any *.dmg file in Windows natively. A *.dmg file is for the Mac environment.
Instead you'll need to download and install a similar programme such as Notepad++ . A good list can be found here:

Best regards

You don't seem to have included any instructions on what software to use to create Main.lua. I'm not that familiar with Mac's, but have got hold of one to develop apps for an ipod touch. The only text editor that I can find only lets me save with set file suffixes, e.g. rtf. Finder will let me rename the file, but not change the suffix from rtf to lua. You might at least provide a source creation and editing suite. Any clues anyone?

And I quote:
"You only need two things to get started with Corona:
A copy of Corona
Any text editor
Many people already have a favorite text editor, but if you don't, we recommend starting with TextWrangler, which is free and can be downloaded here.
You could also use the TextEdit utility that's included with your Mac, but you'll find that it's easier to work with a text editor designed for programming, so try TextWrangler if you don't have a personal favorite.
Later on, you'll need to install Apple's developer kit to test on your iPhone or iPad, or ship your app to the App Store, but you can get started with Corona in the meantime."
