Opening underlords vpk files raises error

ARudiuk commented 5 years ago

When trying to open an underlords vpk file I get the following error

ValueError: File is not VPK (invalid magic)

Code to reproduce

import vpk
import pathlib

path = pathlib.Path("Path/To/Underlords/Folder/game/dac")

path1 = path / 'pak01_001.vpk'

pak1 = vpk.open(path1)

Specifically, this check raises the error

if self.signature != 0x55aa1234:

You need top open pak01_dir.vpk. All other vpk are partitions.

From the command line:

$ vpk /d/steam/steamapps/common/Underlords/game/dac/pak01_dir.vpk
           VPK File: /d/steam/steamapps/common/Underlords/game/dac/pak01_dir.vpk

That works! Thank you.

Sorry for my ignorance of how vpk worked.

Do you think it might be helpful in the future to specify _dir as the only readable files in the readme?

rossengeorgiev commented 5 years ago

VPK can also be just one files where the filelist and content are in the same. Or like here, filelist in _dir and everything else is content partitions. Technically, it could even use both at the same time.
