asset-bundle-analyzer's Issues

'args' not defined

When running the latest version on macOS 10.14 I'm getting this error:
-> python3 analyzer.py /Applications/Unity/Hub/Editor/2019.3.0f6/Unity.app/Contents/Tools ~/work/sizes/validation1-bundles/ Traceback (most recent call last): File "analyzer.py", line 1450, in <module> main() File "analyzer.py", line 52, in main run_tool_with_timeout("WebExtract", filepath, ret_code, 60, 0) File "analyzer.py", line 1416, in run_tool_with_timeout p = Process(run_tool(tool, filepath, ret_code, level)) File "analyzer.py", line 1432, in run_tool path = os.path.join(args.tool_path, tool) NameError: name 'args' is not defined

This happens with both python 2 and 3.
When I roll back to the previous commit on github everything works as expected on python 2. I think something might've gone wrong in the python 3 conversion.

Warning: unhandled type Type*!

Hi.
I used this tool and it is very useful.

What is Type*?
Thanks.

Character maps to <undefined>

Unity Version: 2019.3.8.f1 (Win64)
Analyzer Version: master (49396c2)
Addressables Version: 1.7.5
SBP Version: 1.5.10
Python: 3.8.2 (Win64)

I've ran the analyzer over our set of asset bundles which are generated by Addressables and at least one bundle could not be parsed properly:

Traceback (most recent call last):
  File ".\analyzer.py", line 1450, in <module>
    main()
  File ".\analyzer.py", line 78, in main
    objs = p.parse(datafile + ".txt")
  File ".\analyzer.py", line 145, in parse
    data = f.read()
  File "[..]\Python38\lib\encodings\cp1252.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 21026952: character maps to <undefined>

Beforehand, some warnings about a unhandled type were printed.
Maybe the converted bundle files should be handled as UTF-8?

The analyzer just exits when it reaches this error. Maybe it should continue parsing the rest of the bundles, only printing a warning/error for this bundle?

Indentation error

Tried to run this on a unity build bundles folder and got this error:

Python3 support?

Hi. Python 2.7 will be no longer supported in 2020. Is there any plan to support Python 3?

The script throws memory error if the Assetbundle size is greater than 100 MB
