Gunslugs on PlayStation Vita: Developer Q and A is Detailed

26w ago - Abstraction Games Creative Director Tj'ien Twijnstra shared a Gunslugs PlayStation Vita Developer Q and A with PS Vita fans below today!

To quote: Hey everyone! I'm extremely excited that Gunslugs is finally coming to its natural home, PS Vita, on February 18th. To celebrate the launch, we're offering a 20% discount for all PlayStation Plus members during the first week, so don't miss out!

For the occasion, I figured I'd give you guys a sneak peek at the porting process of Gunslugs; or as we like to call it, an "adaptation" process.

As I have no technical skills whatsoever, I interviewed Rutger Janssen, one of our elite programmers, and Ralph Egas, CEO and [Register or Login to view links] Mastermind. Both developers were involved with the Gunslugs adaptation.

Tj'ien Twijnstra: Rutger, could you tell us a bit about the adaptation process? How does something like that work?

Rutger Janssen: After we determined the base version, the first step is to strip the game code of all the platform specific functions; only the game code remains. Then we take it through our in-house developed tool chain so the basic language is converted from Objective C to C++. Unfortunately, tools are never perfect, so here and there I needed to manually update the code.

As the original platform handles things differently than PS Vita, we need to add placeholder code, called "stubs," to make sure the code starts to compile. Once all the things that prevent the code from compiling are fixed, we slowly replace the stubs with actual functioning code to make sure we get something visual on that beautiful OLED. This process continues up until we have the original game running on its new home.

Tj'ien Twijnstra: Then the fun begins, right?

Rutger Janssen: Yeah, then it's time to add the PS Vita-specific functions. We spent a lot of time tailoring the game. We've added leaderboards, Trophies, and cloud saving, and we made sure the game text was properly localized to different languages. I know you spent ages finding the right font to work with the special characters!

Tj'ien Twijnstra: Don't remind me, it took forever...

Rutger Janssen: That basically leaves us with a complete game, but the process doesn't stop there. We then take it through some serious testing, both in house and using a specialized testing agency to fix bugs in both the PS Vita specific code, as well as some bugs in the original code. After that rigorous testing, Sony QA tracked down some final bugs which we cleared as well.

Tj'ien Twijnstra: Did you think it was an easy adaptation?

Rutger Janssen: Yeah, we did it pretty fast. We learned a lot thanks to our earlier experience with Hotline Miami on PS Vita, so this was a smooth ride.

Tj'ien Twijnstra: Ralph, you told me Gunslugs was a special kind of adaptation for us, could you tell us a bit more?

Ralph Egas: Well, this is one of the first adaptations where we created a special tool chain that allowed us to convert one coding language to another, allowing the basics of one language to easily be translated to another. When we did Hotline Miami we gained experience using some of these tools, so we further developed this tool chain for Gunslugs, which worked really well.

In fact, now that we did Gunslugs, other Orange Pixel games will benefit and become easier to adapt to PS Vita.

Some of you might have heard that Heroes of Loot, Orange Pixel's latest piece of sheer brilliance, is due later this year on PS Vita, so be sure to check this place out in the future.

We hope you'll enjoy Gunslugs when it arrives, but we're also curious to hear from you guys what other games from Orange Pixel you might be interested in. Feel free to let your voice be heard in the comments below (or send us a tweet at [Register or Login to view links]) - we're listening!
