binding NPCs to other NPCs

[nightsta69]

one of the ways i'm tryin to see will work, is during each EVENT_WAYPOINT the main NPC will signal to each minion, and the minion will check itself in relation to its position to the main NPC and readjust. but i'm still learning the perl functions, so still difficult for me.

something along the lines of NPC A signals NPC B. NPC B checks NPC A's $x,$y then checks its own $x,$y. and if they aren't at $x,$y+10, then moveto $x,$y+10. but I can't figure out how to find NPC A's coords with NPC B.

if($signal == 5){
		quest::say("Thanks arias, i'm following you.");
		my $revoltldrID = 189490;
		my $getmobbynpctype = $entity_list->GetMobByNpcTypeID($revoltldrID);
		my $follow_target = $getmobbynpctype->GetID();
		my $x = $npc->GetX();
		my $y = $npc->GetY();
                my $z = $npc->GetZ();
		my $ldrX = $follow_target->getX();
		my $ldrY = $follow_target->getY();
		my $partywalk = $qglobals{$name."partywalk"};
		quest::say("ldrs coords is $ldrX,$ldrY");
		quest::SetRunning(1);
			while($partywalk == 1) {
				if($x == $ldrX && $y != $ldrY+10) {
					quest::moveto($x,$ldrY+10,$z);
				}
			quest::SetRunning(0);
			}
	}

heres what i've come up with, tho I don't think it is getting $ldrX and $ldrY. the global is being defined by another NPC, and it is being defined. seems only hang up is getting the other NPC's coords. any help would be greatly appreciated.

I redid it, cause after looking at it, it didn't look right to me. noticed a few errors.

if($signal == 5){
		quest::say("Thanks arias, i'm following you.");
		my $revoltldrID = 189490;
		my $getmobbynpctype = $entity_list->GetMobByNpcTypeID($revoltldrID);
		my $follow_target = $getmobbynpctype->GetID();
		my $x = $npc->GetX();
		my $y = $npc->GetY();
		my $z = $npc->GetZ();
		quest::say("my coords are $x,$y");
		my $ldrX = $follow_target->getX();
		my $ldrY = $follow_target->getY();
		my $partywalk = $qglobals{$name."partywalk"};
		quest::say("ldrs coords is $ldrX,$ldrY");
		quest::SetRunning(1);
			while($partywalk == 1) {
				if($x != $ldrX || $y != $ldrY+10) {
					$npc->moveto($ldrX,$ldrY+10,$z);
				}
			quest::SetRunning(0);
			}
	}

now i'm certain the only problem is having NPC B find NPC A's coords, cause NPC B will tell me his, but won't tell me NPC A's.
