Error loading gui resources at startup stored in .ung file

[ivan.cuevas]

Hi all,

 

After moving to new Ungine 2.2, I've realized Ungine fails at initialization trying to load gui resources in a folder different from core (by specifying <item name="gui_path" type="string">my_app/gui/</item> in config file) if these resources are packed in a .ung file.

 

I've checked the .ung file by extracting the content and verifying the files are present and without any case variation in their names (they have exactly the same name as Unigine expects). In fact if the files are not archived the engine starts as expected.

Hi,

 

We have some success in reproducing this issue.

It'll help however if you provide more detail.

Which one engine binary are you using: debug or release?

Are there any error messages in the log when engine fails? (by default engine saves log to the "bin/log.html")

Hello Ivan

We've found some problems in work with ung-files, but we could not reproduce your case
Сan you send us small test scene for reproduction?

 

Thanks

[silent]

Hi Iván,

 

We've made some changes to ung resources loading in 2.2.1 update. Could you please check if that helps in your case? If not, could you please send us minimal test scene?

Thanks!

[ivan.cuevas]

Hi paralyzah and silent,

I'm afraid this problem isn't resolved in 2.2.1.

I will prepare a test scene as soon as I can.

 

Thanks for your help.

[ivan.cuevas]

Working in a test scene I've found a behaviour that is confusing me.

• I've created a project using browser.
• I've modified data folder into another called unigine. So in both .bat files and in the config files set

• -data_path "../unigine/"
  

• I've created two copies of <data>/core/gui folder inside <data>/test_data_path as gui and gui2. In both folders I've changed the gui_background.png image to quickly see what gui skin is using.
• Two .bat files to launch the application using each custom skin. And with another difference, the launch_debug_gui2.bat specifies gui parameter and launch_debug.bat using the gui path specified in config file.
• I've created the test_data_path.ung with the content of the folder with the same name.

First test - Using test_data_path folder

• launch_debug_gui2.bat: the application works Ok.
• launch_debug.bat; the application works Ok.

 

Second test - Using test_data_path.ung

• launch_debug_gui2.bat: the application works Ok.
• launch_debug.bat: looks like it uses default skin ignoring the configuration.

 

It's not exactly the problem described above, but it's a strange behavior and maybe it can help to find a solution.

 

Thanks.

Hello Ivan
Thank you for test-scene - it very helped to understand what is the problem
Correct  me if I am wrong: you want use custom gui_path, and it is not detected correctly, if engine_config was packed in ung-archive?
Unfortunately, engine can not be initialized from cfg-files in ung - it's by design, we add remark in our documentation about it
You only have next ways: not to put cfg-file in ung-file or specify gui-path in command line as you do it in your test-scene, also you can replace default gui-folder in core.ung
Sorry for the inconvenience caused.

[Priyank.Jain2]

I am facing similar issue. We are currently migrating our product from Unigine 1 to Unigine 2.3.1

 

We are using ung files to specify external directories. 

 

I have analysed the problem and checked the engine source code as well. Since in till Unigine 1, you can only set 1 data_path and gui_path default value is "core/gui/" BUT now in Unigine 2.3.1 we can set multiple data_paths and gui_path gets override

    // preparing gui path
    gui_path = normalize_dir_path(gui_path);
    if (!Dir::isAbsolute(gui_path))
        gui_path = data_paths[0] + gui_path;

Now I think even if I pass gui_path by config or command line, it will get override.

 

Please let me know if my understanding is correct. Also provide me a workaround.

[ded]

Hi Priyank,

 

This override for gui_path is wrong.

As long as I can see all resources for GUI are loaded via engine file system and there is no need to provide an absolute path.

I've removed this two lines in the development branch:

    if (!Dir::isAbsolute(gui_path))
        gui_path = data_paths[0] + gui_path;

I suggest you remove them too in your copy of SDK.
