Hurray my first app is running!  (I really just copied the RUBE penguin game and changed things around).  It plays great on Windows, on MacOS, and in the IOS simulator.

 

So I installed it on my Android phone, and the game plays.  However, the images controlled/loaded by RUBE are all missing.  Any RUBE entities where I replace the image/sprite using QML code work fine (so my character, challenges on screen, etc show up fine).  But the images controlled/loaded by RUBE are all black.  And, in the Application Output window I see errors that the images are missing!!

 

Here’s the strange thing.  The same directory that stores images like “sky-background.png” also hold images like “lightning.png”.  My QML code displays the lightning and it shows up fine.  The sky-background image is controlled by RUBE, and it reports as missing.  You can see the errors below, and I also show the files present in the build directory (holding both sky-background and lightning).  So the files are there, but RUBE parser / entity manager can’t find them.

 

So, I assume this has something to do with assets, relative path, maybe qrc (which I’m not using), rube entity manager, etc. but I can’t figure it out.  Can anyone suggest how to fix this?

I compared the Windows build to the Android build, and the structure and location of my png files is unchanged.  Somehow under Android the Felgo MultiResolutionImage is not finding the png file!

 

Stuck 🙁

Hi Larry,

Looking at the sidescroller.json file content, are relative paths to the images correct within your assets folder?

Best,

Alex from Felgo

Yes, the paths are correct (confirmed by the ‘ls’ output above).  Interestingly the game plays fine on Windows, Mac, and IOS (simulator).  So I think if the paths were wrong they would all have the same problem?   My file structure is:

MySimpleApp
 |
 +--qml
 +--assets
      |
      +--rube
      |    |
      |    +--sidescroller.json
      |
      +--img
      |    |
      |    +--lightning.png
      |    +--skybackground.png

 

As a test, I moved my assets into QRC files and then everything plays fine even on android.  So this seems like a MultiResolutionImage issue
