Recent update notes
Plugin Developer
Today's update is minor and you should see no functional changes.  However, note that permission is (now) explicitly required even for the admin.  Hopefully the documentation is both correct and more useful.  Finally, if anyone can help me understand resistances, please let me know.  I suspect that it is resistance to damage for the machine but I am not yet sure.
in the config there's a resistance list that has 'stab' 'bullet' 'explosion' etc etc and beside it a number from 0.0 to 1. So i think you're correct that it's just the resistance to damage from specific types of damage.
