AttributeError: 'Scene' object has no attribute 'scannerProperties'

[ozge-albayrak]

Hi!
I am trying to use your toolbox for my application and I would like to utilize your scripts. In order to do that I have tried to run the script_usage.blend file. However, I am getting the following error.

File "C:\Program Files\Blender Foundation\Blender 2.93\2.93\scripts\addons_contrib\range_scanner\ui\user_interface.py", line 1565, in scan_static properties = scene.scannerProperties AttributeError: 'Scene' object has no attribute 'scannerProperties'

Since I am pretty new to Blender scripting I couldn't quite figure out the issue.
I would appreciate if someone can guide me in the right direction.
Thanks!

Hey @ozge-albayrak, could you please have a look under Edit > Preferences > Add-ons? The checkbox for 3D View: range_scanner needs to be checked, otherwise the add-on is not installed properly.

Hi!

Thanks for the reply! I am trying to use scripting only rather than GUI. Thus, I have followed the steps given for only "Script Usage". Apparently, you don't need to copy paste the range_scanner folder into Blender 2.93/2.93/scripts/addons_contrib folder. Once I removed that folder from addons_contrib and checked the checkbox of 3D View: range_scanner, I think the add on was installed properly.

Now, when I run the script_usage.blend file, the rendering starts, however, the script fails and I get this error.

Do you have any comments on this? I really appreciate your help in advance!

Could you please upload a minimal example as .blend file?

[ozge-albayrak]

Sorry for extremely late response. I am using the script provided by use called script_usage.blend in the example_scenes folder. And when I run it I get this error.

In case anyone else is confused by this: ticking the checkbox in the GUI is still necessary even if you are using the script-usage instructions.

I can reproduce the only integer scalar arrays can be converted to a scalar index error. It is obviously related to the sonar scanner but I could not figure out yet why it happens although it seems to be configured the same way as in the sonar_example.blend example.
