maybe something like...

Code:

local el = EntityList("chartype=4")
if ( el ) then
   local i,e = next(el)
   while (i~=nil and e~=nil) do

      // Your stuff

      local i,e = next(el,i)  
   end  
end

i don't test it but i think this will give you near players. The problem here is the invite part, bot doesn't have chat support
