Description of the new feature

with this feature it is possible, to Send Information from DB-Scripts up to a CreatureAI or ScriptedInstance.

Usally this is useful for Spells with SendEvent - which should do something to an existing creature (which might not be the target of the spell)

Also this can be used to control Instance behaviour from Gossip or similar, because InstanceData::ReceiveEvent has arguments for additionly information

Description of the fields

dataint is used to determine if the information shall be passed to CreatureAI or to InstanceData;

in Case of Creature:

* if in datalong is given an additional entry the script will search in range(datalong3) for the closest creature with entry)

* if not, the script will try to access the target/ source depending on data_flags (0 => target, 1 => source)

might be useful for quest_accept and gossip selects

in Case of InstanceData:

* datalong is the mapId (additional check), datalong2 is the additional transported data

A few examples

* http://www.wowhead.com/spell=23054 There is a Kroshius lying around, so I think this one should react to the Event, and not just having a new one spawned.

* http://www.wowhead.com/spell=16533 This should start a complete Event - So I think the instance-hook is useful

* http://www.wowhead.com/spell=28374 should have effect on the zombies of the Gluth encounter - I think this can be best done via instance_ script.

Edit: small adjustment, to also get source for ReceiveEvent without using a GridSearcher with data_flags

I hate to bump myself

Updated version to recent, but only checked for compile

Came across this here due related discussion at SD2, would be very nice if a Dev might give a comment

Being able to send script events to C++ scripts is a big step forward for implementing a lot of "events", such as the epic warlock mount event in Dire Maul. Thanks Schmoozerd.

[Schmoozerd]

lol - never thought of DM, but this surely is a warlock feature (started because of Kroshius)

Cool you can use it!

Tested on [10217] and works perfect.

Very awesome!

i have a broadcast-like event messaging system that uses grid notifiers to send events in aoe range, if someone is interested i could post it.

[Schmoozerd]

to whom do you send in range? (Creature, Player, Go? - how do you work with it?)

Where do you need it?
