Witches’ Brew – Halloween potion making fun! featured by Amazon as Free App of the Day for October 25th. If you have an Android device or a Kindle Fire, this is your chance to get it for free right before the Halloween! This is the full version that is normally $0.99, and recently updated to remove OpenFeint & unnecessary permissions…

We have decided to sell remaning time on our Corona SDK PRO license to anyone who might be looking for an opportunity like this to get started with it…
This is a PRO license that covers full privileges and supports iOS & Android… License has approximately 7 months left, expires at 2012/10/21
If you are interested in buying, simply pay using the PayPal buy button below. As soon as we receive your payment, I’ll let Carlos know about your name & email and he will do the license transfer…
Edit: It looks like (please refer to the comments) I misunderstood what Carlos said on the forum and the license is NOT transferrable. So, if you are looking for a license, you should buy it directly from ANSCA. If you are serious about the game development, it’s totally worth the investment. I’ll leave this post here for future reference for any one who might be looking for that information…
As you might know, we have recently decided to move away from CoronaSDK. Decision made based on our own requirements and expectations, but that won’t change the fact it still is a very good SDK which is capable of making hit games.
Anyway, due to that change we also won’t be using Corona Project Manager anymore and decided to sell our license to anyone who might be interested. I have confirmed that with Jay (CPM developer) and the license is transferable, so we are good to go…
Our asking price is $50 (1/3 off than the original price, $75), that is 33% discount…
If you are interested in buying, simply pay using the PayPal buy button below. As soon as we receive your payment, I’ll let Jay know about your name & email and he will create a new license for you…
My license is sold, thank you! But if you are looking to purchase CPM, act now. It’s the best add-on for CoronaSDK I’ve ever used!
Due to recent developments, we will no longer be using Corona SDK. If anyone wants to know why, all I can say is that’s because of all the little things stacking up on each other such as:
I still think CoronaSDK is an good alternative but simply, it’s not suited for us anymore…
Btw, following CoronaSDK projects maintained by us will be discontinued as well. If anyone wants to continue working on those projects may do so freely.
* This project is taken over by Jay himself, thank you Jay…
If you are serious about mobile development using CoronaSDK there is one tool you should definitely check out, Corona Project Manager by J. A. Whye. For me, it’s an organic extension to CoronaSDK and makes it very easier to work with.
One of the most important features of CPM is the autocomplete function. It speeds up my coding but also it reminds me the functions I might have forgotten at the time, or functions recently added which might make things easier. Because of that, I’d like to keep it up-to-date. You may copy & paste the following list to keep yours updated as well! ;)

While working with CoronaSDK I ended up using ui.lua for the buttons in our upcoming iPhone/iPad game. But I had hard time locating the latest version as many other developers had their own versions.
So, I have decided to make an ultimate latest version that will combine all previous enhancements along with my own. Copy of that Lua code is still available at Ansca code exchange.
NEW: Updated to eliminate the use of LUAs deprecated module() function. This is an internal change only, usage stays the same.
NEW: Added event support, now returns even.target, event.x & event.y values. You can use x/y values to provide different actions based on the coordinates of the touch event reative to the x/y size of the button image.
NEW: isActive state enhanced, so the button can be enabled/disabled without checking current isActive state with if-then.
-- ui.lua (currently includes Button class with labels, font selection and optional event model)
-- Version 2.4
-- Based on the folowing original provided by Ansca Inc.
-- Version 1.5 (works with multitouch, adds setText() method to buttons)
