   We finally ported Stick Stunt Biker to android using cocos2d-x. cocos2d-x is really mature already, we just discovered a few bugs here and there, but everything works rather nicely now. Integration of openfeint, market place, etc.. is easy too.

   

   Market place: https://market.android.com/details?id=com.djinnworks.stickstuntbiker

   If you have any questions or need help porting your game feel free to drop us your questions.

   Thank you guys!

   Very cool, nice to see an existing game ported over using this. What kind of bugs did you run into? Did you have to make any changes to the layout of your code (for example to support different resolutions?).

   CocosDenshion. This one is really buggy in the android port. Other things include wrong accelerometer orientation on various devices, screen resize issues, etc.

   We manually changes the entire layout to a 960x640 design and just use autoscale with letter boxing for a few resolutions.

   Do you think that your future games will be done in cocos2d-x only so you can have one codebase for both platforms?

   I dont think it is possible to use the same codebase for our beloved iOS, and ... that other thing ...

   Gave this a try last night on a recently androidified hp touchpad. Scales up nicely on the 1024x768 screen with just a small top and bottom border.

   @Codemattic: This is actually a good questions we discuss internally a lot. It really depends on the revenue the android market generates. If the revenue is interesting enough we will most likely make everything with cocos2d-x. ( As long as cocos2d-x gets maintained as good as cocos2d-iphone and incorporates new features and bug fixes quickly.). On the other side, porting from cocos2d-iphone to cocos2d-x is rather trivial and can be done quite fast (it took only 6 days to port Stick Stunt Biker). So, we are not sure yet, we will see :)

    6 days? Nice. How many devs?

    
    

    For anyone in the know: Will cocos2dx plug into a phonegap style app? Just in case I decide to develop for ... the other thing ...

    ok - so are there advantages to developing in cocos2d-iphone over cocos2d-x? One advantage may be developers like ObjC more than C++. Another is that more dev work goes on in maintaining cocos2d-iphone (idk - Im guessing)?

    I love ObjC/IB, but for building iOS and Mac GUI apps - the features of ObjC really make it terrific for that. But there isnt a clear advantage to ObjC for game dev IMHO.

    Also - it seems like cocos2d-iphone gets a mad amount of development effort. Version 2 is pretty exciting. 3d extensions. Level editors and such. But I dont know enough about cocos2d-x to really say.

    I guess it depends on the size and audience of the Android Market. Also, remember the Stick games already have a reputation and customers in the iOS App Store - so if sales arent as good for you in the Market it doesnt necessarily mean the Android Market isnt a viable one - you are starting later and with no name recognition there.

    Please let us know how this goes!

    Also what do you test on? I mean its tough to test iOS, you want to test iPad 1 and 2, iPhone and iPodtouch over the last couple of generations, and 3 resolutions of regular, retina, and iPad. Probably also over the last two iOS releases.

    But thats nowhere near the wacky hardware variations and OS variations seen in Android. Screen sizes, processor/gpu/memory differences, different OS versions and flavors.

    Different markets! Do you send it to Amazon's market? Just Google's? Verizon's app market? Make a version for the Kindle Fyre? You could nned a full time employee just to manage all those markets!

    Yeah, testing gets a lot of more work once you port to Android. On iOS once your app runs on the lets say iPhone 3G your app will most likely run on all other iOS products. Not so for Android, we had crashes on single devices, not working features on other devices, etc.

    
    

    For Stick Stunt Biker we test each release on:

    - iPod, iPhone 2G, iPhone 3G, iPhone 3GS, iPhone4, iPhone 4S, iPad and iPad2

    - Samsung Galaxy

    - Samsung Galaxy II (we had a lot of graphical glitches there, e.g. you have to disable depth buffer, etc.)

    - Samsung Galaxy Tab (we accelerometer troubles there)

    - Nexus S

    - Nexus One (rather slow)

    
    

    There are more really annoying differences like texture formats, you can use PVRCT on a few devices only, you need other texture formats for other devices, etc.

    On Landscape devices the accelerometer is assembled in landscape too, meaning you have to rotate the axis yourself

    Etc.

    
    

    The only really thing we like about developing for android is the compile-download-test time. It just takes 2 seconds from pressing compile until the app runs on the device. This is something Apple could really work on for iOS devices.

    
    

    Regarding the different markets, good point. We just released on the android market until now. Will check out all this other markets...
