Hi I have been playing with the code in the player.qml and I’m trying to animation to the character to explode when he hits the pipes but I am unsuccessful. If anyone can give me tips I would really appreciate it

[ChristianFelgo Team]

Hi Jeff,

you could for example add a new Sprite element in SpriteSequenceFromFile with your explosion animation and then start it on the signal gameOver of the player. Like this:

    Sprite {
      name: "explode"
      frameNames: [
       //your explosion animation frames
      ]
      frameCount: ...
      frameRate: ...
    }

And in player:

  onGameOver: spriteSequence.jumpTo("explode")

Hope this helps!

Hi, i’ve built Flappy Bird application with the Build Server and it does not run in Android 2.3. I’ve never entered the Android API Level, and i wonder to know where is such option. Did you compile it for Android?

Thanks!

Mariano

Hi Mariano,

all apps built with Felgo are available for Android 2.3+, so it should be possible to run Flappy Bird on your device.

Did you just build the Demo source which comes with Felgo SDK? What exactly is the problem?

 

Cheers,

Chrisu

Hi Chrisu, yes i just downloaded de source code of the demo and i could build it and run it on Windows. Then, i uploaded the zip of the qml folder to the build server, and i dowloaded de .apk. When i run the application in my phone the screen gets black and it never loads. The only thing that “works” then, is the back button that makes a confirmation message to appear several times and then i must press home button to sitch to another app.

 

The API level for wich the Build Server compiles the app isn’t changeable? What about another options like if i use Google API?

My phone is an LG-E400g with Android 2.3.6

Thanks

Mariano

Hi again,

could you maybe try the APK on a different device or on the Android emulator?

Yes the minimum API level is always the same for all Felgo apps, because all Felgo plugins are designed to work on Android 2.3 upwards.

Cheers,

Chrisu

Hi again, i’ve tested the app on Android 4.1.2, and it runs just fine. I’ve installed the same apk i tryed before on Android 2.3.6. Could it be a problem in the build server? or maybe it consumes too much RAM or some resources for the cellphone with Android 2.3.6?

 

Thanks

Hi Mariano,

I see, it seems to be a problem with your LG phone. It seems rather old, might be a problem with OpenGL or it’s graphics processor.

Could you try some of the other Felgo apps like Chicken Outbreak (https://play.google.com/store/apps/details?id=net.vplay.demos.ChickenOutbreak) if they work on this device?

 

Hope we can figure this out!

Cheers, Chrisu

[Mariano]

Hi Chrisu, Chicken Outbreak runs just fine. So, do you think is it some limitation of the cellphone?

I’ve tested other applications similar to “Flappy Bird” and the run.

https://play.google.com/store/apps/details?id=com.nb.flappychicken

https://play.google.com/store/apps/details?id=it.junglestudios.splashyfish

https://play.google.com/store/apps/details?id=com.seriouscorp.clumsybird

 

I’m looking for a framework for making games that could be run in old cellphones with Android 2.3, because they still represent a considerable part of the market. Is it any way of making this game “lighter”?

 

Thanks

Mariano

[ChristianFelgo Team]

Hi again,

if the other apps similar to Flappy Bird run on your device, then your custom build should run as well.

Could you try uninstalling some apps on the LG phone, maybe there is not enough space?

You could also try creating a publish build, sign it and test it on your phone, since these builds generally use a bit less resources.

Can you also try to build just a very basic sample project, like the one that Felgo creates when you create a new “Empty Felgo project” in QtCreator and see if that works on your phone?

 

Cheers,
Chrisu

Hi Chrisu, i was testing some apps and i remembered this problem with flappy bird tutorial on mi LG-E400g with Android 2.3.6. I’ve connected it to my PC with LogCat and I’ve seen some Qt errors. I paste the log here:

I’ve programmed in C++ with Qt the last years, and i see one familliar problem..

WARNING: QApplication was not created in the main() threa

In Qt the QAppliation object Must be in the main thread because it has the main loop where all GUI events and related signals are processed.

http://qt-project.org/doc/qt-4.8/qapplication.html#details

I hope it helps to figure out the problem, so i can run the app on old android 2.3 phones. They still represent the 20% of the market today!

Thanks, regards

Hi Mariano,

we ran the Flappy Bird demo and all other sample games successfully on Android 2.3 devices.

Do you get any error in the log that indicates why your app is crashing?

Did you try to run a simple game template (like the Empty Felgo project) on your Android test device yet, if it also crashes?

Cheers, Chris
