[Bf-extensions-cvs] SVN commit: /data/svn/bf-extensions [2520] contrib/py/scripts/addons/ object_drop_to_ground.py: ok i got it to work, it seems object. location was creating the problem so i used the operator translate and it works now .

I'd suggest looking into randomize transform operator that does this
without using operators

I also implemented a gui with min max , for  x,y,z axis to make randomisation more precise. Well keep testing, if randomisation exceeds boundaries of ground then the object will not drop on the ground which i think its normal behaviour, will also put a warning at the wiki
