why you despawn stalker, if you dont check for it?
idk... but you dont need check if stalker is "alive" before aplly spell on player?

[Keader]

it's sniffered?

[Re3os]

http://www.wowhead.com/npc=38463/empowering-orb-visual-stalker
http://wotlk.openwow.com/npc=38463

[Keader]

yes... but why you despawn NPC_ORB_VISUAL_STALKER?
You dont need check if he is alive/spawned before apply buff on player?
you checked this object on retail or checked in sniffs?
This code looks wrong... despawn an npc for "nothing" because he are not used...
You realy sure that player should cast this spell?

[Keader]

Still is wrong
Check with sniffs how this object realy works...

[Keader]

i will try make this gob script ^^ (i never did gob script before, but i will try haha)

This spell only work in Crimson Hall Quarter.
I'm have no expertise with gob scripts... so i cant send you one version without hacks, because:

Idk how reproduce this behavior : https://gist.github.com/Keader/06d3abba8a47d7b4a04f481767eaa696#file-sniff-txt-L78-L79 this change flag without "force" with script.
Idk how remove GO_FLAG_NOT_SELECTABLE without force in gob script (maybe some field em DB?)
Without override GossipHello, Spell are casted, but "broken" animation dont work (he did broken animation, but restores orb). On retail, he should broken the orb and despawn/destroy after 3 sec... idk how despawn a gob after x time...

Btw, if someone with more expertise try fix it, maybe it helps: https://gist.github.com/Keader/06d3abba8a47d7b4a04f481767eaa696

PS: active (boolean variable) is for avoid multiple players clicking at same time or clicking multiple times

Gossip Hello? I remember - object has spell or visual stalker has spellclick, but not gossip hello.
Darkfallen also can get buff from blood orb. If npc get buff - go removed. If player get buff - go removed. But buff has various id.

[ariel-]

GossipHello is called for gameobject on Use (I agree it could have a less confusing name, like OnUse)

[Keader]

@Ulduar you know what trigger start cast of Siphon Essence?

[ghost]

@Keader Darkfallen npc from thrash pack (around orb) - warning: WHO PULLED FIRST. Cast 70299.
On out of combat random npc from thrash pack around orb cast 72099 - simple visual spell.

[Keader]

ok, now i need free time to try do this behavior and understand how gob scripts realy work haha :)

[ghost]

Why are you so desperate to do in C ++? Do you think it's easier? And then the crash fix it fun?

[Keader]

i realy dont know how objects works in database... when i mean gob scripts == search how DB handle with it, if only db dont works, add c++ part...

Idk how reproduce this behavior : https://gist.github.com/Keader/06d3abba8a47d7b4a04f481767eaa696#file-sniff-txt-L78-L79 this change flag without "force" with script.
Idk how remove GO_FLAG_NOT_SELECTABLE without force in gob script (maybe some field em DB?)
Without override GossipHello, Spell are casted, but "broken" animation dont work (he did broken animation, but restores orb). On retail, he should broken the orb and despawn/destroy after 3 sec... idk how despawn a gob after x time...

Btw, if someone with more expertise try fix it, maybe it helps: https://gist.github.com/Keader/06d3abba8a47d7b4a04f481767eaa696

For example.
https://trinitycore.atlassian.net/wiki/display/tc/smart_scripts

SMART_EVENT_GO_STATE_CHANGED
70
State (0 - Active, 1 - Ready, 2 - Active alternative)

You can use condition with number 31.
https://trinitycore.atlassian.net/wiki/display/tc/conditions

CONDITION_OBJECT_ENTRY_GUID
TypeID. Available object types:
3 : TYPEID_UNIT
4 : TYPEID_PLAYER
5 : TYPEID_GAMEOBJECT
7 : TYPEID_CORPSE (player corpse, after spirit release)

0 = Any object of given TypeID
if TypeID = TYPEID_UNIT => Creature entry from creature_template.entry
if TypeID = TYPEID_GAMEOBJECT => Gameobject entry from gameobject_template.entry

0 = Any object of given type
1 - 500k : creature / gameobject GUID

Change Go state on you needed. And try. But remember: this is not full script, because has different condition (CONDITION_SMART_EVENT can help you). If npc activated - npc get one buff, if player activated - get other buff.

[dr-j]

Well there is more to this too players cant even click the orbs but when one of the npcs starts channeling stand next to the npc which is channeling when channeling is completed both npc and player standing next to it will get damage increase buff from orb.

[ghost]

@dr-j SAI allow on npc aggro (if npc start channeling) - set go flag not_selectable. Or handle on spellscript.
And only one npc from thrash pack can cast channeling spell (in combat and out of combat).

Around the orb there are 4 NPC (6 NPC in 25 mode). When aggro - the battle takes all the trash pack by creature_formation it can be done. But only the one who struck the first - will start casting channel spell.

On the timer out of combat - random one of these NPC starts to cast visual effect channel spell. Without script handle. 72099 - out of combat spell visual - no required script handle.

I still want to understand - CONDITION_SMART_EVENT works for source_type = 9? And is it possible for one smart_script id add more conditions (logical AND)?

[Faq]

With all the gob recent changes should possible.

[Keader]

working on it :)

[Keader]

Object scripted, spells related scripted
Missing script on minions around him, generic script done... now i need add spells 💃

[Keader]

Sad, i cant continue right now... without sniffs about creatures :/
Our sniff, people kill they too fast, i cant get all spells
trying get sniff about it to continue.

-- Edit

I got some sniffs yay \o/

[Keader]

Well, still dont have sniffs about trash mobs around orbs.
