Show Geeks:

If you are new to the conversation, the Corona SDK is a cross platform mobile development tool kit that makes it easy for developers to create native applications for Android and iOS devices as well as for Kindle, and Nook. You can find out more about the Corona SDK at http://www.CoronaLabs.com.

A few things we discussed during today’s hangout:

Lastest Build Release Notes

Corona Announcements

  • Corona Labs is expanding the Corona SDK engineering team and administrative staff. In terms of developers, Corona Labs has added an additional 50K developers to their rolls since the beginning of Summer 2012. That’s a significant amount of growth, so yeah Corona Labs!
  • Dr. Brian Burton, who is writing the materials for the Corona Certified Developer Program and who is also a regular here at Corona Geek, says that the course materials are in their final stages and should be ready to go soon. No dates were discussed, but developer certification is definitely something we can all look forward too.

Community Questions
Hector Sanchez @AppsGlobal said on Twitter, “I still get confused about proper use Accelerometer and Gravity. Sometimes I confuse them when moving objects.”

Since we didn’t have a specific use case or example to address, we decided to cover some of the basics of gravity versus accelerometer. Here are a few of the resources we referenced during the show.

Animate Sprites and Methods

  • There are two approaches leading to a similar result:
  • The old (and now depreciated) sprite.* library.
  • The current sprite APIs that work cohesively with image sheets and the display.* library.
  • If you haven’t implemented the current methods or haven’t ever used sprites in Corona, this tutorial will walk you through the process.
  • The tutorial also introduces the full array of sprite event listeners and how to implement them. – Example: jump from a slow running cat to a fast running cat.

App Review – Fainting Goats – $0.99
According to the developers, “The game took just over three months to make, with around two months of that using Corona. We were working on the game only part time and had to learn Lua in the process.

Toff purchased the app for his kids as entertainment for a road trip to Florida. Apparently that was a good choice because he says even though there were two kids in the back seat of a small car, there was lots of laughing and loads of fun. Even months after the trip the app still remains installed on the device and the kids still actively play the game. Watch the video review for 7 year old Joshua’s full review.

iOS App Store Clause
According to iOS App Store Clause 2.25, “Apps that display Apps other than your own for purchase or promotion in a manner similar to or confusing with the App Store will be rejected.” Each of us share our opinions about this clause and what it may or may not mean to developers. Check out these articles for other perspectives on the topic.

    Mobile friendly websites really seem like a no-brainer but I can’t tell you the number of times that I’ve been to a website that promotes mobile apps that is not mobile friendly. I wonder if this is just because people don’t think about it or if it’s just the level of effort required. I guess it also depends on what the definition of mobile friendly website is.
