Anyway will make little, or no difference since the speed would be millisecond differences.
Single hash file.. add them using.
/hadd -m tablename N action¬comment
Note; action and comment are seperated by, ¬ which is $asc() number 172
Where, tablename is the hashtables name, N is the Nth number added, 1, 2, 3, 4, or you can just use $calc($hget(tablename,0).item + 1) to calculate the Nth number automatically in a sequence, action would be i.e. slaps, hits, knocks, and comment would be with baseball bat, with hammer, ect.
Then you would use.. //echo -> $hget(tablename,$rand(1,$hget(tablename,0).item)).data
to return a random entry in the form.
action¬comment
then you simple use, $gettok($hget(tablename,$rand(1,$hget(tablename,0).item)).data,1,172) to get the 'action' and $gettok($hget(tablename,$rand(1,$hget(tablename,0).item)).data,2-,172) to get the comment.
Hope this helps, if you need more explaining, just ask.
