Thank you. It helped

I'm trying to update the project with upgrade.py to the new version of the SDK (2013-08-16). In the console window I see a lot of errors such as

 

Starting upgrade, ignored list: ['.svn', '.cvs', 'core']

upgrading E:\Bagram\/bin/Bagram.world [world]

Error: can't upgrade E:\Bagram\/bin/Bagram.world

upgrading E:\Bagram\/data/.world [world]

Error: can't upgrade E:\Bagram\/data/.world

upgrading E:\Bagram\/data/project_afg/afg_test.world [world]

Error: can't upgrade E:\Bagram\/data/project_afg/afg_test.world

upgrading E:\Bagram\/data/project_afg/layers/aircrafts.node [world]

Error: can't upgrade E:\Bagram\/data/project_afg/layers/aircrafts.node

and so on.

 

The file errors.log is not generated! I used a search that would find it.

Help me to upgrade the project to the new version of the SDK.

Hi,

 

From which version are you trying to upgrade?

Could you please sent us couple of your project files, such as afg_test.world, aircrafts.node for reproduction?

 

Thanks!

In the console says:

---- Editor ----

Version: 0.69

 

See errors.txt file. This is the console output to a file.

files.rar

Hi,

 

Please try to specify different path (without backslash at the end) in --target:

• upgrade.py --target E:\Bagram\data

Thanks!

Hi,

 

Could you please tell us what kind of troubles are you experiencing when you trying to open your project with new version of SDK?

Engine log file from <SDK>/bin/log.html will surely help us to get to the root of the problem faster.

 

Thanks!

I installed the new sdk in folder "D:\Unigine source SDK".

My project is located in a separate folder "E:\Bagram". Accordingly, the files in the E:\Bagram\bin refer to the old version SDK.I need to update my separate project to the new version of SDK. How can I do this correctly?

Now the project is working without any problems, but the editor version 0.69. I need version 0.70 with new features.

 

Thanks!

Hi,

 

First of all, backup the old project files (All directory E:\Bagram). After that you can just copy files from new SDK to your old location with overwrite option. Or you can copy your project into the new SDK folder and launch it from the new location.

 

Unfortunately, if you have modified Unigine core scripts inside <SDK>/data/core and <SDK>/data/scripts directory they will not work or can be incompatible with new versions. Also, if you have modified engine sources it would be hard to port your changes to the new versions.

I have solved my problem!

I did not immediately find this manual: https://developer.unigine.com/en/docs/1.0/code/prototypes/scratch/scratch_customize#update

Sorry to bother you.

 

But I do not understand for what the script  upgrade.py? Do I need to run it after the upgrade bin files?

[silent]

Ok, that's great :)

 

 for what the script  upgrade.py?

It needed if internal format of files were changed (*.node *.mat *.world, etc). This kind of updates are always highlighed in the release notes.
