A few weeks ago, raycasting was added to Corona’s physics system. The core API is an easy-to-use function for casting a “sensor ray” into the physics world — and we didn’t stop with that. Soon after, reflection was added to the raycasting system. Today’s tutorial discusses both of these features and includes a downloadable demo project to assist with your own development.
This week’s brief tutorial discusses some new properties that are available to Corona Pro users since Build 1086. In specific, Android users can now get the physical screen DPI and size of various devices, and iOS users have some new API properties related to Apple’s move away from UDID.

Today’s tutorial features Lua string manipulation and parsing techniques which can be useful in several applications, especially business or database-powered apps where you need to check and confirm that text is formatted properly. Read further to learn about these string-related helper functions.
Today’s tutorial features two more physics methods. In specific, we’ll discuss “radial gravity” and how to visually predict the launch trajectory of an object. Better yet, both methods are available as downloadable projects so you can explore the full implementation at the code level. Read on to learn more!
A common question in the forums and elsewhere is how to thoroughly clean up scenes when using a scene manager like Storyboard or Director. This week’s tutorial discusses some common misconceptions and “tips and tactics” that you can use to properly manage memory in your app.
For some multi-platform developers, building for Android is planned from the beginning but it’s not fully implemented until after the launch of the iOS version. However, there are several things that should be done while building a cross-platform app to make sure that Android’s unique functionality is handled in advance of submission to the marketplace.
This week’s tutorial examines the use of network.download() and remote data files to update app content “on the fly.” Using an XML file, we’ll also examine how to manage these remote assets properly. Read on to learn how!
Performance optimization is a topic that concerns all developers and spans all genres. Today’s tutorial discusses 10 useful performance tips that are not necessarily “familiar” to Corona developers. Read on to learn how these tips and tricks can improve the performance of your app.
Today’s tutorial discusses the remainder of the new widgets introduced recently, available in Daily Builds. These include the “table view,” “scroll view,” “picker wheel,” and “progress bar.” Read on to learn about the features of these new widgets and how to easily implement them into your Corona app.
