X86 Android Support

Saturday, 21 December 2013 3 comments

We have recently added X86 Android support to our engine and toolchain, this means that users who have mobiles/tablets running X86 CPUs will find our games run faster and consume less battery. While X86 support has been offered by the Android Software Development Kit for a while now, we have only recently seen a large push by Intel to get more X86 mobiles and tablets into the market (such as the Galaxy Tab 3):

We have uploaded new builds, with X86 support, for the following Android titles:

1. KAMI RETRO

2. Wacky Rapids

3. KamiCrazy

Our efforts have not gone unnoticed, as Intel has selected our titles to be showcased as part of a promotion they are running in 2014 to push X86 phones/tablets. We will post more information as this campaign is rolled out.

KAMI RETRO Android Update

A new version of KAMI RETRO is available for download on the Google Play store. It contains various engine side improvements that have been made, and also contains a few more substantial improvements including:

1. Assets are now included with the APK this means users no longer have to wait for the game to download the assets on first launch. This simplifies the process of users playing the game, which can only be a good thing.

2. There is now X86 support, for the X86 mobiles/tablets that are becoming increasingly popular.

3. Scoreloop support has been added (with global leaderboards and awards)

We still have a steady stream of users downloading and playing KAMI RETRO and we hope the above improvements will benefit both new and existing players.

Flash Support

Some of sessions we attended at GDC Americas this year focused on the current available technologies for getting C/C++ based games/engines running in a web browser. When the Google Native Client SDK was released some time ago we investigated how we could harness this in order to run our games inside Google Chrome, and while this is still of interest to us, we were a little put off by the fact it only supports the Chrome browser (perhaps this is something we will come back to).

Two of the other potential technologies are Emscripten and Crossbridge (was FlasCc). Emscripten is a technology that ultimately takes your C++ code and 'converts' it into Javascript, which can then be run under any browser (in theory it runs in any browser, although in reality the main browsers support is pretty well although other browsers have limited support). We investigated Emscripten but felt the technology was not yet mature enough for our adoption. We then investigated Crossbridge, which takes our C++ code, compiles it into bitcode that can execute under the Flash runtime (it actually compiles to LLVM bitcode first). We were able to get our codebase compiling and linking against Crossbridge relatively quickly, although the build times are rather slow and memory intensive (it requires over 6GB of memory, and a fully optimized build can take 30 minutes to build on a reasonable specification machine, which leads to a slow development cycle)!

With our Flash .swf version of our games/engine built, it took a little while to debug various problems that stopped them from running. Again it felt like the technology is not yet fully mature, but we stuck with it and overcame all the issues, meaning we can now run all of our games in the web browser (via Flash). Helpfully, there is a GL wrapper that allows our native GL calls to be mapped onto Stage3D Flash calls (Stage3D is the GPU accelerated layer that can be used for Flash), and we were able to use a software OpenAL implementation with a small output driver we wrote to send the final mix to a Flash audio output.

We are pleased with the end result, all our games run at solid 60 FPS in the browser, and given that we develop our games on the PC, and control them using the keyboard and mouse, means the games play well in the browser too. There is a certain 'magical' feel of seeing our engine being able to run in this way.

In terms of releasing our games via Flash, we are currently exploring what options are available. There are a few portals which are set up to allow developers to earn revenue from Flash games, although this is an area which is new to us. We would like to see our Flash games available for everyone to play, although right now we don't have a road map for this happening. Stay tuned for more information.
