Despite the good advice on just using a library or someone else’s solution to getting game center working, sometimes I’m just stubborn. Well it wasn’t actually completely stubbornness as it was more of a “don’t have an alternative” situation. Tilt to Live uses AGON for it’s leaderboards and awards system. It has served us well and never faltered. Despite that, Game Center has arrived to rain on it’s parade so-to-speak. To give TTL hopefully more life in the long run I decided to implement Game Center alongside AGON over the past week....

We sent off Tilt to Live HD to Apple for review today. I couldn’t send it off until around 3 PM today because my internet was down (since 6 AM) due to a less then stellar ISP here in Alabama. *sigh*. But that won’t get me down, I’m super excited that TTL HD will be on the ipad app store in a few short weeks! Right now I’m busy trying to cut and edit footage together for a launch trailer....

A friend of mine sent me this list of anti-patterns common in software engineering. Being the lone developer on my team, I don’t get to see anyone else’s code except mine on a project. As a result, it’s hard to critique whether my code is “good” or not. That was one of the benefits of working at a company I suppose. Being surrounded by those with more experience than me, I would learn a lot just from an afternoon of working on a section of code that wasn’t mine....

After reading Noel’s post on prototyping I realized I was drifting away from that mind set and getting into dangerous territory of just “thinking up a game and running with it.” Tilt to Live itself spawned into a full game from being discovered in a rough prototype. Since then we’ve just had rough documents and ideas that we wished to pursue after TTL. The past few weeks we’ve been gearing up more heavily for our next game and I’ve been getting back into the habit of whipping out fast prototypes....

I recently made a post on our official OML blog about what Adam and I are playing. Taking a look at that list you’ll find that the vast majority of games I play are multiplayer oriented. A lot of biases, inspirations, and design decisions that go into my game designs are influenced by multiplayer games. When we set out to start One Man Left, my long term goal for the company (beyond making fun games we like to play) was to be known for making fun multiplayer indie games for whatever platform we develop for....

I had an issue where several international users were reporting that the game was crashing. As it turns out, using an NSNumberFormatter would return a weird character to display as the grouping separator. This would be all good and dandy, but the problem lies in the fact that I’m using bitmap fonts to render, and the look-up failed causing a hard crash. In Tilt to Live’s case, this was in regards to how number grouping symbols are displayed in different locales....

I spent this past weekend getting retina display graphics implemented in Tilt to Live for iPhone 4. The cynic in me hates the marketing term ‘retina graphics’ because on the production side, it’s simply just a bigger image. But I guess you do need a name for it, and since ‘HD’ has already been bastardized on the iPad I guess this will do. I decided to write this post to bring a bit of awareness to some of the process of updating your OpenGL game for the retina displays if you choose to do so....

It’s been hellishly busy as of late, as I’m knee deep in Tilt to Live HD. Now on with my quick blurb: This tip is kind of a “duh” much in the same way version control software is for most developers. The thing is I still meet a lot of developers who don’t use any form of version control. And automated builds simply weren’t even in my own tool set initially....

Tilt to Live has been unleashed on the unsuspecting public! So far the general vibe has been extremely positive! Adam and I are both pretty excited about getting our first app store game out the door. What’s interesting is the workload went from “lull” to “overdrive” in a matter of days as we ramped up for release and still are trying to coordinate things for a bigger media push in the coming weeks....

So I’m using OpenAL to do the audio in Tilt to Live. Over the course of development audio became the bottleneck of my game, both in size and in performance. The following could help you if you’re experience audio performance issues and are somewhat new to OpenAL. Let me preface this with: Don’t blindly optimize. Measure, Measure, MEASURE! Know what your bottleneck is before trying to tune code! Don’t make more than 32 sources objects in OpenAL....
