how are creatures linked?

[Auntie Mangos]

Edit discussion for my patch focused to http://getmangos.eu/community/topic/15909/in-dev-creature-linking-via-database/

A little bump

I revamped my old SpawnSpecial system, rewrote it entirely, and changed to some different behaviour.

So I got a (very basic) system for linking creatures together.

it can be seen here: https://github.com/Schmoozerd/mangos/compare/master...CreatureLinkingMgr

Current functionality (only npcs by entry supported)

   FLAG_AGGRO_ON_AGGRO         = 0x0001,       the "slave" aggroes when the "master" aggroes
   FLAG_TO_AGGRO_ON_AGGRO      = 0x0002,   the master aggroes when the slave aggroes
   FLAG_RESPAWN_ON_EVADE       = 0x0004,  the slave respawns when the master evades
   FLAG_TO_RESPAWN_ON_EVADE    = 0x0008, the master respawns when the slave evades
   FLAG_DESPAWN_ON_DEATH       = 0x0010, the slave despawns when the master dies
   FLAG_SELFKILL_ON_DEATH      = 0x0020, the slave goes suicide when the master dies
   FLAG_RESPAWN_ON_DEATH       = 0x0040, the slave respawn when the master dies

planned are

- following

- CanSpawn when boss alive

- CanSpawn when boss dead

Feel free to give any ideas on missing features or things that can be done better

Hi,

I just want to ask, how creatures in mangos are linked, for instance I pull a single npc (who stands in a group) in a dungeon and a few seconds after I pulled him, the whole group follows him and start to attack me, like on retail.

But how does the server handle this? Is there a db entry for linked creatures or how does it work.

thx

They're not really linked I guess, it's just that when you hit them they call for help and make nearby creatures attack the same player.

(See Creature::CallForHelp)

They should probably be grouped together somehow, but they aren't. It's just a call for help within range thing.

[faramir118]

Not all groups of monsters are linked on retail, only some of them.

In some cases, if your group dies before you kill all linked enemies, the ones you did kill will respawn.

Yes, this is another dynamic. There are also other examples of shared scripting, movement, etc that are based on grouping. The grouping is mostly in instances, where you can clearly see mobs spawned together in groups.

Yea, and call for help is used by acid as a action.

Are the grouped creatures already implemented in mangos, so that when one member die and rest evade, the dead One get respawned? Or is acid call for help the only way to "link" creatures (for now).

[Schmoozerd]

there is currently no system to handle spawning, shared aggro etc in mangos.

for avoid duplicate thread and etc, please create thread for patch and link it in bug reports instead direct links and chaos
