Proximity check for surrounding NPCs

[Figback65]

Hi all,

I am trying to have a NPC do proximity check that will check for any NPC in the proximity.

The purpose of this is, im starting from scratch and im trying to globally do a scripted distance chain aggro so I can bypass factions. Also other uses.

I have read that NPC proximity can only check for PC. If thats the case. there is also the

 if(plugin::CheckDistBetween2Ents($npc1, $npc2, 50)){

stuff. If this is set to a timer and I want it to check for ANY NPC within the range, would I use an array of all my npcs in the zone or whatever i want it to link to?

Everything I have tried so far has failed, am just looken for direction. Hopefully I can write it when on the path lol

Thank you.

I've written small tutorials for NPC list iterations in the entity list:

http://wiki.eqemulator.org/p?Entity_...ow_to_Use_Them

Anytime you are using $client or $npc, those are IMPLIED entity objects.

You can create your own entity objects by fetching them selectively in your code.

$some_boss = $entity_list->GetNPCByNPCTypeID(40005); # Example
$some_boss->Say("hi");

You would use that same object in the distance check

 if(plugin::CheckDistBetween2Ents($npc, $some_boss, 50)){

If you want to find all NPC's say within 50 units of the NPC you are triggering the code on, you would do something like this:

my @nlist = $entity_list->GetNPCList(); #::: Use Entity List Object to get this
foreach my $n (@nlist){ #::: Iterate through each NPC in the @nlist array
	if(plugin::CheckDistBetween2Ents($npc, $n, 50)){
		$n->Shout("Hi I am an NPC that is within your distance check");
	}
}

Nice! Thank you, reading over it all now

Well I would think this would work, been worken on it and tryen to get it to work but it does not and i am blinded by the reason why.

Its fairly simple, It looks like it would work but it doesnt.

sub EVENT_SPAWN{
quest::settimer(1, 3);
}
 
sub EVENT_TIMER{
	if($timer == 1) {
		my @nlist = $entity_list->GetNPCList(); #::: Use Entity List Object to get this
		foreach my $n (@nlist){ #::: Iterate through each NPC in the @nlist array
			if(plugin::CheckDistBetween2Ents($mob, $n, 50)){
			#$n->AddToHateList($client,1);
			$n->Shout("Hi I am an NPC that is within your distance check");
			}
		}
	}
}

How is the script bring initiated and how are you testing

[Figback65]

I have the script on 2 npcs in a zone by themselves. I agro one from a distance and run it by the other one to check if they recognize each other to eventually chain aggro.

Add debug messages to see what conditionals are working versus not

[Figback65]

sub EVENT_SPAWN{
quest::settimer(1, 3);
}
 
sub EVENT_TIMER{
	if($timer == 1) {
	quest::say("timer hits");
	my @nlist = $entity_list->GetNPCList(); #::: Use Entity List Object to get this
		foreach my $n (@nlist){ #::: Iterate through each NPC in the @nlist array
		quest::say("got entity list");
			if (plugin::CheckDistBetween2Ents($npc, $n, 50)) {
			#$n->AddToHateList($client,1);
			quest::say("im too close");
			}
		}
	}
}

Included debugging. I get to pulled entity list. So checkdistbetween must not be working. I had noticed early i didnt have your additions for it in the pluggins, so i snagged those and restarted server. But that was a while ago.

Script above works, Thank you

EDIT: Now I just gotta get the agro to share lol

Finalized Template to get npc to npc distance checks and add agro, to script agro linking for whatever reason you may want. I will be usen it for many reasons including bypassing faction linking on a wiped custom server.
GetHateRandom can be changed to whatever you like, GetHateTop works as well, depending what you want to happen.

sub EVENT_TIMER{
	if($timer == 1) {
	my @nlist = $entity_list->GetNPCList(); 
		foreach my $n (@nlist){
			if (plugin::CheckDistBetween2Ents($npc, $n, 20)) {
			$n->AddToHateList($npc->GetHateRandom());
			}
		}
	}
}

Modified for use as a "guard" without using faction. Basically you can change the target NPCIDs to have the guard attack specific npcs that come close enough.

#2211 Enclave_Protector in postorms v.1

sub EVENT_SPAWN {
	quest::settimer(1,6);
}

sub EVENT_TIMER {
	if($timer == 1) {
		my @nlist = $entity_list->GetNPCList(); 
		foreach my $n(@nlist) {
			my $typeID = $n->GetNPCTypeID();
			if($typeID >= 2213) {
				if(plugin::CheckDistBetween2Ents($npc,$n,50)) {
					$npc->AddToHateList($n);
				}
			}
		}
	}
}
