Access state information from object `dmlab2d.dmlab2d_pybind.Lab2d`?

[violetxi]

I am using an environment built on top of DMLab2D, and wondering if it's possible to obtain complete state information (player and object's transform information etc) of a grid world in addition to the observations and ascii maps? Ideally access to the information described here:

I have tried read_property('') and encountered permission denied error.

I have tried to call read_property('') but encountered permission denied error.
