SpriteGrabber is the easy way to use spritesheets in Corona for including animated and stationary graphics in your project. With SpriteGrabber you need to write significantly less code compared to directly calling the SDK functions. Moreover, you don't have to remember the index numbers for the frames of your sprites, since SpriteGrabber calls sprites using their image-names. Technically, SpriteGrabber is a helper... More...

Creating the charts is simple, a QR code can be generated like this: 1 2 3 4 5 6 7 8 9 10 11 local qrCode = charts.newChart { type = "qr", data = "Corona Rocks!... More...

Exercises some of Corona's "secret" OpenAL features as described in our blog entry The secret/undocumented audio APIs in Corona. Also uses simple sprite animation and some Widgets (requires Corona build 579 or so). Please use with care. Support is very limited; the Corona OpenAL APIs used here may change or be removed entirely. Additional Information: More...

I've made a virtual dpad to test a tilt-based project and came out with something I think will be really useful for those out there wandering how to make a virtual controller for their apps. Its features are: - Visible only at finger touch. - Tracks angle and magnitude. - Draggable from its bounds. - Confined to screen limits. The download link and a video showing the thing in action can be found at our website:... More...

The closest bit of code I could find online was actually provided by Carlos (https://developer.anscamobile.com/forum/2011/05/02/need-some-help), but I found that his solution of appending new points onto a single line got laggy the...

This is a sample that will render some fractal art using lua and the Corona API. A few years back, I took an interest in fractals and was curious about how to make them. This sample is a port of a C++ sample I wrote back then, showing how to create Mandelbrot and Julia sets. Here you can toggle between them by pressing the toggle button in the lower right corner. There is a small delay on start up as it calculates... More...

I've recently created a module for lists for one of our apps and I think it is worth sharing. It basically creates lists, both vertical and horizontal using strings (for text lists) or display objects (possibly groups). It is highly customizable. Lists behave like iOS lists where one can scroll farther than the end, and upon release the lists gets back to the last element. Also has momentum for fast scrolling of... More...

See the commented-out text below for notes on how to change the ticker text or Twitter feed that displays. If you copy this... More...

Another common forum request. This will show some spawning, touch handling with table listener and object removal. Also shows some forward declarations for the "cart-before-the-horse" issue.

In the field of computer graphics, due to limited CPU performance, textures are often use to create the notion of movement. Here I upload a simple demo that demonstrate several features of Corona. 1) eventListener 2) sprites 3) alpha channels In this demo, I use an alpha channel trick, plus a random water texture, to make it look as there is water motion.

The grass next to the road goes by fast while the trees in the middle of the field look slower. Meanwhile, the far away mountains look like they are barely moving. This is the essence of parallax.
