Safe from the Losing Fight

I’ve already posted the press release for Hearts Attack, but I thought I’d share a little about how Hearts Attack came about.

Way back in 2008 the original iPhone SDK came out, and I, like a lot of people, was excited about developing apps for the iPhone. My company is primarily a software development services company so I was mainly interested in learning the SDK so we could pick up iPhone contracts in addition to Mac ones. It also happens to be the case that my favorite card game is hearts, so I decided a good way to learn the iPhone SDK was to write my own hearts game.

After a couple of weeks I had the basic functionality implemented, and noticed I was playing it a lot. I realized then that I could probably make this into a product. Furthermore, releasing an iPhone app through the App Store seemed like a good way for us as a company to begin making the transition from a services based company to a product based one.

If I was going to release Hearts Attack as a published app, I knew the UI and presentation had to be greatly improved. I went through a lot of mockups for the main playing view, including one where everyone’s cards — all 52 of them — were always visible somewhere on the table (a truly horrible idea). Unfortunately I don’t seem to have most of the mockups around anymore, but I found a couple which you can see below. (See the product page for the end result.)

The biggest challenge I had was fitting everything on the screen and it still being legible and usable. By trial and error I figured out how small I could make the cards and still make them tappable, as well as their optimal position to make them accessible with one hand.

I began thinking about what would make Hearts Attack unique or different from its competitors. Back then there were literally just two iPhone hearts games in the App Store, and I felt pretty confident that what I had was already better than them, but I wanted to be sure. I decided on: oddball talking computer opponents, a tutorial that gave not only card suggestions but the rationale behind the choice (a pet peeve of mine), and multiple undo support for mis-taps and tactical errors.

The last step was to get professionals to do the sound and graphics. I ended up hiring a sound designer, a graphics designer, and a character illustrator. The sound design went smoothly, but getting the graphics done was a lot more involved than I anticipated, which is another story for another day. Jordan of OneToad Design created the app icon, playing backgrounds, and the special card backgrounds for the queen of spades and jack of diamonds. Lara Kehler did the character illustrations, which turned out great.

Unfortunately, Hearts Attack went on hiatus in early 2009. I was working full time on an iPhone contract, and simply didn’t have a lot of time to put into Hearts. Secondly, I had lost all desire in finishing it. It was becoming increasingly apparent that iPhone users didn’t want to pay more than $0.99 for anything, despite all the whining I did about it. I convinced myself it wasn’t worth releasing Hearts because it would never make back the money it cost us to make. Hearts stayed dormant for an entire year.

A couple of months ago, I decided to pick Hearts Attack back up again. I had the time and, as someone pointed out to me, it would never make money if I didn’t release it. I was tempted to update the app to the latest SDK (I started Hearts back before you could even use nibs on the iPhone) and add some features. I decided against this, because I really just wanted to ship it. I did have to update it to the 2.2.1 SDK because the current Xcode tools no longer ship with the 2.0 SDK.

Instead I focused on fixing the bugs and adding polish. Fortunately for me my wife happens to be a professional software tester with iPhone experience, so I got lots of good bugs to fix. I also prepared a press release, created a website, and otherwise got ready for the release. After I felt the app was stable enough, I submitted it to Apple on Friday. It was approved on Monday.

At this point, I’m still not convinced I’ll ever make back the money we spent on sound and graphic designers. A hearts card game simply is never going to be a big seller, and price point isn’t high enough to make up for that. Right now, I’m tending to think pessimistically about sales, but I’m going to do what I can to drum up sales and see how things go.

It’s a “wait and see” situation as to if we develop any more iPhone applications to sell ourselves. Of course, regardless of how well Hearts Attack does, we’d be happy to develop your iPhone app for you.

Dallas, TX – Order N Development today announces Hearts Attack 1.0 for the iPhone and iPod touch. Hearts Attack allows users to play any of the common variations of the hearts card game, such as omnibus, shooting the sun, and spot hearts against a variety of zany computer opponents. Hearts Attack includes a full in-game tutorial, suggestions, and multiple level undo, allowing beginners to easily pick up the game. It provides four difficulty levels to challenge even experienced players.

The player competes against three of seven possible colorful computer opponents, each of which has their own distinct looks and personality. The personalities range from a communist kitten trying to overthrow oppressive humans to a vegetarian vampire to a pacifist pirate who sells insurance. They always have something interesting to say about how they and their opponents are playing. The computer opponents can be configured to play at trivial, easy, normal, or hard difficulty levels.

Unique to Hearts Attack is its in-depth tutorial system. The tutorial begins by giving the player a brief introduction to the rules and strategies of hearts. Throughout the game it offers suggestions for which cards to pass or play, including the rationale for choosing those cards. The suggestions are useful to beginners learning how to play, and to more advanced players looking to improve their game. The suggestions can be used apart from the tutorial.

Since players always have their favorite way of playing hearts, Hearts Attack allows flexible configuration of the rules. Players can choose how cards are passed, which player leads and with what card, how penalty and bonus cards are scored, and what is required to shoot the moon or the sun.

Company Information

Order N Development, LLC is a software engineering company providing contracting services for the Macintosh, iPhone, and iPad platforms. Order N Development was founded in 2002 in Dallas, TX by a small band of experienced Mac developers. Copyright 2002-2010 Order N Development, LLC. All Rights Reserved.

For the uninformed, NSConference is a Mac developer’s conference put on by Scotty “The Scottster” Scott and his faithful sidekick, Tim “The Faithful Sidekick” Isted. They’re kind of the Batman and Robin of the Mac programming conference world, but have a slightly lower probability of bat-gassing you than the real dynamic duo.

This year they aren’t content with bringing conference justice to only the UK, so they’re branching out to the good ‘ole U.S. of A. by way of Atlanta, GA. To help you decide which conference you should attend, US or Europe, I’ve prepared the following quiz:

1. What is your opinion of Seattle?

   1. It’s nice, but isn’t nearly rainy or dreary enough.
   2. I like their coffee.
   3. The residents have too many teeth.

2. Describe your driving habits

   1. I like to drive on the left side of the road.
   2. I like to drive on both sides of the road.
   3. I like to merge right six lanes without signaling while going 147 mph on the off ramp and giving the finger with both hands in my black Camaro.

3. The pinnacle of human achievement is…

   1. Afternoon tea
   2. Sliced bread
   3. Hee Haw

Scoring: Give yourself -1 points for any 1 answer, 0 points for any 2 answer, and 1 point for any 3 answer.

If you scored is less than zero, you should attend NSConference Europe; if greater than zero, NSConference USA. If you scored exactly zero, you are truly a cultured individual and should attend both.

Personally, I’ll be attending both, and not just because of peer pressure and insightful quizzes. I’ll be presenting a talk on how to implement a watercolor brush using Core Image and OpenCL and maybe some duct tape. If you enjoy the graphics articles that I post here, you’ll probably enjoy my presentation. If not, I hear Steve “I’m Batman” Scott does a mean Adam West impression.

Update: I was contacted by an Apple engineer saying this bug was fixed in 3.0, and asked if I could reproduce it there. I tried my sample project again, and I was unable to reproduce it on 3.0. This problem only seems to affect 2.x devices.

Not too long ago I was profiling an iPhone app that I had written for a client. Their testers had found that using a certain feature for long enough ended up causing the app to be ejected because of a low memory situation.

After some quality, yet painful, time with Instruments I discovered I was never deallocating image memory in the form of CGImageRef and its internal drawing cache. (It turns out that if you draw a CGImageRef while on a thread other than the main thread, it creates a cache of the bitmap data. However, this wasn’t my problem.)

At first I thought I simply forgot to release the UIImages somewhere. I put in some logging code and was able to confirm that I was releasing the UIImages the correct number of times, in the right places. But it appeared that someone had called retain on it an extra time.

That’s when I happened to notice that only the UIImages I had constructed with imageNamed: were failing to be released. I suspected that they were being retained in a global cache. The only problem with this cache is not released in low memory situations. Even when my app receives a low memory notification and I free up all the memory I can, the UIImage global cache just sits there clutching it’s unused UIImages to its chest, muttering.

Unfortunately for me, some of the UIImages I was loading were large, and I was expecting them to be deallocated when I released them. As the feature was used, different UIImages were loaded with imageNamed: and never released until the phone ran out of memory and my app was ejected.

The solution was to write a replacement method for imageNamed: that didn’t cache the UIImage. Here’s what it looks like:

@implementation UIImage (OrderNDev)

+ (id) imageNamedNoCache:(NSString *)name
{
	NSString *basename = [name stringByDeletingPathExtension];
	NSString *extension = [name pathExtension];
	NSString *path = [[NSBundle mainBundle] pathForResource:basename ofType:extension];
	return [[[UIImage alloc] initWithContentsOfFile:path] autorelease];
}

@end

The moral of the story is imageNamed: is only for use with small images that are used constantly throughout the app’s lifetime. Don’t use imageNamed: if you want that memory back on a 2.x device. Everything will work fine on a 3.x device though.

I’m starting to think about marketing, PR, and what not for my iPhone game, so I’m trying to come up with a list of iPhone specific sites that might be appropriate targets for press releases and/or advertising. Since I have a game, game specific iPhone sites are even better.

It also occurred to me that other developers might be gathering this information, so I thought I’d post what I’ve found so far here. I got the idea from MobileOrchard.
