I’ve been using Ansca’s Corona SDK for almost a year. I made the decision to use Corona because it allowed rapid development via Lua, and the SDK met almost all of my needs at the time I chose it.
I’ve made numerous contributions to the Corona Community, and even donated my time in solving other people’s issues. Because of my strong belief in the SDK I signed up to be a Corona Ambassador.
Over the past few months something has become painfully obvious to me and a number of other Corona developers. Corona just doesn’t have the support it should. The software development process is flawed and because of this they keep pushing out Daily Builds that are buggy and cause any of a number of issues for developers.
Just go into the Corona Forums and you will see what I mean. One common thread goes something like this:
“I’ve had lots of problems with Corona. I write up the issues on the Forums and hear nothing back from Ansca. If I do get support it’s almost always from another developer who has gone down the same road and run into the same issue. It seems like the community is figuring out solutions to more of the problems than Ansca is. What gives?”
The above isn’t an exact quote, but it is a compilation of a number of complaints developers have had. As a Corona Ambassador I try and jump in and solve the issue whenever possible, but that doesn’t work when it is a fundamental issue with Corona.
For instance, recently I submitted 3 apps to the Barnes and Noble Nook store. All 3 passed for Nook Tablet, but all 3 were rejected for the Nook Color. I searched high and low for differences between the platforms, but other than the Color having half the memory of the Tablet and some differences in the video card and clock speed, they are supposed to be identical. Our apps only use 80MB of memory so it shouldn’t have been due to memory. After spending days trying to figure out what might be happening, I contacted Ansca and asked them about any issues they might know regarding the Nook Color. This was Ansca’s response:
yes we are aware of this issue. We think it’s due to some rendering changes a week ago on Android
On the one hand, I was glad to hear it was a known issue. However, why didn’t they post something in the Corona Developer Forum letting people know to hold off on Nook Color submissions? I mean really, if you know there is an issue, then why keep it a secret?
One typical response goes something like this: “the daily builds are NOT stable and we make that very clear”. Sure, that is very true. However, since the stable builds only come out a few times a year, and because there are KNOWN crash bugs that have been fixed ONLY in the Daily Builds what is a developer to do? What until the next stable build? That could be weeks or months away and we have no idea when it will occur.
Here’s another example of the instability of Corona. We recently submitted 3 apps to iTunes. All 3 were accepted and are now available in the iTunes store. Almost immediately we started getting complaints in our reviews from users that the game wouldn’t load. These negative comments materially affect our business. Having people make comments that our games are crap or that our company sucks is NOT good for business.
So we posted an update to our description asking people who experience the problems to let us know what device and OS they are using. The response so far is iPhone 4, OS 5.1.1. Of course we had tested on this device, but we believe the user is having an issue so we do some more testing. Our app runs fine for us. If you know much about software development then you can probably guess that the issue is almost certainly an uninitialized variable. That would cause it to work fine sometimes and not other times.
Guess what? Any uninitialized variables have to be in the Corona SDK as it uses Lua for the developer coding and Lua sets all variables to “nil” unless you explicitly set them to some other value. That means that our code will run the same way from one run to another, unless you are past the load and into the game where random numbers get used. Since the app just gets a black screen at start-up for the user, it is clear this is not in our code, but something in Corona.
Ansca, PLEASE fix these issues. PLEASE stop with the Daily Unstable Builds. PLEASE put out regular stable builds every 2 weeks, every month, whatever period works for your team size.
I want to continue using Corona as it is a very nice solution when it works. However, if these issues aren’t resolved soon I will be forced to move to another SDK (and there are a number of them now).
