I am not sure exactly how one would do this but my friend said he had
redone the entire processing system to use Que's.
I am sure that it could be very useful in several ways by using it as an
extension to the processing also.
But like i said in the origonal post it seemed an appropiate topic for the
mailing list. So play with it and I would like to see what other people
think, ect... (I am currently to busy to code for circle but like to see
idea's :)
BTW: The dig command was discussed briefly a while back about burying items
and diggiing them back up. I got my version workering but I am not sure how
stable the code is. And the TinTin probs where mentioned with this idea of
having TinTin do the command every time a char enters a new room and the
majority chode WAITSTATE as a good solution. (I could never get my wait
state to work the way I wanted :(
If anyone is interested i could put the code in the list for dig and bury

I doubt that this will increase performance a lot.
Binary search (as used here) takes about 20 acesses on max.
64000 32000 16000 8000 4000 2000 1000 500 250 125 62 32 16 8 4 2 1
You don't save a lot in this case with your improvement.
The zonereset lag may be caused by virtual memory pageing of your
host (this is more likely). The only solution for this is to
upgrade the host you run on with some simms.

Let's try to define an event:
(unverified code !! 5 min hack !! needs work !!):
/* Created by Katzlberger Thomas <katzlbt@vuse.vanderbilt.edu> */
struct Event
{
Event* next;
Character* ch;
int when;
char* doWhat;
ASPELL(*spellfun); // optional
ACMD(*cmdfun); // optional
...
Event(Character* c,char* what, int w=0)
{
ch=c;
doWhat=str_dup(what);
when=w;
}
tick(Queue* q)
{
if((--when)<=0)
execute(q);
}
execute(Queue* q)
{ command_interpreter(ch,doWhat);
free(doWhat);
q->remove(this);
}
};
game_loop:
eventQueue->tick()
// calls tick in all Events, executed every 8th tick or so
^^^^^^^^^^^^
Usage:
eventQueue->addEvent(new Event(ch,"say damn",8));
// char says damn in 1 tick *grin*
Depending on the needs it takes - for better performance -
a Queue that sorts its events by the time they will occur.
and just processes the top element. This is the classical
application of a priority queue or heap.

Well waitstate doesn't work for this purpose as
it blocks any input from the player:
WAIT_STATE(ch, PULSE_MOBILE)
send_to_char("You start digging",ch);
This should keep him busy for 10 secs but you never
get control back from the player unless he makes some input.
... here goes an event ...

Yes I can try to fix it.
But where do you store the buried objects ?
