Today’s tutorial explains exactly how Corona handles these events and which events are broadcast to which objects.

Tutorial: Game controllers and axes

In a previous tutorial about HID controllers, we showed you how to read button inputs from game controllers. In contrast to basic button functionality, analog controls are more complex because they measure an almost infinite number of potential values that must be converted from the analog “infinity” to discrete digital values. Today’s tutorial walks you through the process.

Tutorial: Understanding In-App Purchases

In the mobile development world, studios have been looking for more models to monetize their product. This doesn’t just impact games, as business app developers are finding it more challenging to monetize as well. This week’s tutorial discusses some important details about In-App Purchases (IAP) and how to implement them in your Corona app.

Tutorial: Non-physics collision detection

Corona SDK has a robust physics-based collision detection system, but it requires some extra processing behind that scenes that you typically don’t need if you’re not using physics for other purposes. Today’s tutorial explains how to detect collisions between two circles or two rectangles without using the physics engine.

Tutorial: Stylizing Widgets, Part 1

This week’s tutorial discusses how to visually stylize widgets. Although widgets will adopt the OS-like appearance by default, in many cases you’ll want to customize the appearance to suit the style of your app. In this part of the series (1), learn how to properly style the button, table view, stepper, and spinner widgets.
