Updates overviewer.dat file sign info
|
|
|
|
This script will scan through every chunk looking for signs and write out an
|
|
updated overviewer.dat file. This can be useful if your overviewer.dat file
|
|
is either out-of-date or non-existant.
|
|
|
|
To run, simply give a path to your world directory and the path to your
|
|
output directory. For example:
|
|
|
|
python contrib/findSigns.py ../world.test/ output_dir/
|
|
|
|
Once that is done, simply re-run the overviewer to generate markers.js:
|
|
|
|
python overviewer.py ../world.test/ output_dir/
|
|
|
