Hello all!
@find .real_name => a list of objects with the real name property just fine.
;$player_db:find("mao") => the player whos name is "mao"
;$player_db:find(".real_name") => fails even though mao has a property
.real_name
here is a screen dump:
@find .real_name
The property .real_name is on Wizard(#2)--generic player(#6)
mao(#165)--generic player(#6)
;$player_db:find("mao")
=> #165 (mao)
;$player_db:find(".real_name")
=> #-3 <$failed_match>
What am I missing?
Thanks,
-m

Ok, this makes sense...

$player_db:find is a function which takes a name and returns a player's
object number. You're asking for the player whose name is ".real_name"
and I am not surprised you don't have one.

ah, I was confusing the finds.
what I am looking for is something, similar to @find .real_name, that I can call like I was hoping to be able to do with $player_db:find(".real_name").
I want to get at a list of players (that have real_name set) so that I can compare the property real_name to a variable.
What would be the best way to approach this?

$object_utils:descendants_with_property_suspended($player,
"real_name") is probably close to what you need.

Maybe..
result = {};
for p in (players())
if (p.real_name)
result = {@result, p};
endif
endfor
return result;
?

Or, thinking more, if you make it result = {@result, {p, p.real_name}} it
saves having to go and get the .real_names again later.

Not familiar with that one - I will look into it.

This was close to the route I was planning to go at if there was no 'given':
result = {};
for p in (players())
if (p.real_name)
if (p.real_name == usr_name)
result = {p, usr_name};
break;
endif
endfor
"carry on with result...";
I can stop on finding a match as these names are guaranteed unique.

This would be perfect for collecting the list I was referring to. I mentioned list because that is what I thought 'find' would return and I figured I'd walk through that. Will hang on to the above though!
Many thanks everyone and a good weekend to you.

problem is this one can return non players aswell, and might miss players
that aren't children of $player(Odd, but it happens:)

for p in (players())
if (p.real_name == usr_name);
return p;
endif
$command_utils:suspend_if_needed(0);
endfor
return #-1;
would probably work best if you're gonna use a seperate verb:)

You'd have to go use $list_utils:assoc() on this one afterwards tough:)
