Building an iOS App in Corona Labs SDK

Corona SDK - now Corona Labs SDK - is a great tool for building games for iOS and Android. What about building more traditional and standard looking apps? Well, Corona provides a number of widgets which look and behave just like regular iOS controls. Putting these together shows that a few items are missing, but can be built. Corona SDK's Sample Code directory contains a WidgetDemo, to show off the functions provided by the API's Widgets. Here's my list of posts for improving those features:

Corona Collision Filters

Ansca Mobile (www.anscamobile.com) have created a truly brilliant multi-mobile-platform SDK (iOS, Android) called Corona, which includes a Box2D (www.box2d.org) physics engine. There are many implementations in many languages for Box2D and one of the things which Ansca have got right is collision filters, one of the trickier things to implement in an physics API.

Brent Sorrentino of IgnisDesign has produced and posted a helper chart for working out which collision filters various objects should be assigned when building physics-based games using Corona:
