Error on examples

[nalo26]

Hello !

I'm trying to make the example program block_analysis works, but it doesn't. I saw the other error report, but it still doesn't work in 1.13.2.

Parsing region r.-1.-1.mca...
Traceback (most recent call last):
  File "test.py", line 144, in <module>
    sys.exit(main(world_folder, start, stop))
  File "test.py", line 115, in main
    process_region_file(region, start, stop)
  File "test.py", line 73, in process_region_file
    for c in region.iter_chunks_class():
AttributeError: 'RegionFile' object has no attribute 'iter_chunks_class'

I tried to replace iter_chunks_class with iter_chunks but, I then get the following error on the next line, which I do not understand :/

Parsing region r.-1.-1.mca...
Traceback (most recent call last):
  File "test.py", line 144, in <module>

  File "test.py", line 74, in process_region_file
    cx, cz = c.get_coords()
AttributeError: 'NBTFile' object has no attribute 'get_coords'

Is there a way to fix that and/or update it to 1.14.x or anything ? Thanks ^^
