c++ SCript for the Quest Zero Tolerance and spellfix spell_zuldrak_gymers_grab #31196

Thor1423 · 2025-08-05T18:17:26Z

I personally think that the whole thing can be designed better with c++, so here is my c++ idea

Here's my link with the C++ code and two videos
#30286 (comment)

UPDATE `creature_template` SET `AIName` = '', `ScriptName` = 'npc_servant_of_drakuru' WHERE `entry` = 28802;

 -- Servant of Drakuru smart ai
SET @ENTRY := 28802;
DELETE FROM `smart_scripts` WHERE `source_type` = 0 AND `entryOrGuid` = @ENTRY;

-- Servant of Drakuru Text
DELETE FROM `creature_text` WHERE `CreatureID`=@ENTRY;
INSERT INTO `creature_text` (`CreatureID`, `GroupID`, `ID`, `Text`, `Type`, `Language`, `Probability`, `Emote`, `Duration`, `Sound`, `BroadcastTextId`, `TextRange`, `comment`) VALUES
(@ENTRY, 0, 0, "Darmuk must die, mon!", 12, 0, 100, 0, 0, 0, 28884, 0, 'Servant of Drakuru - Say on Charm');

This is my first PR so please forgive me if I forgot something

this must be outside of class

we don't manipulate EventMap in ctor

SpellInfo cannot ever be null here

this is redundant, cast ToPlayer and then check for nullability in that case

this checks per ms, use an event to delay the checks by 500ms-1s

Essentially, the script does exactly what it's supposed to, and therefore there were no compilation errors in the logs or in the game.

I assumed it was solid code that I had created with the help of a friend from back then. You can see in the video that it does what it's supposed to.

But okay, I'm not a professional programmer and I'm not afraid of corrections during the learning phase. So I'm sorry my first attempt isn't good enough for you.

Just because a piece of code doesn't throw errors, exceptions, or cause crashes doesn't mean it's optimized to its best. You don't need to check that particular case every tick of Update, it's okay to delay it by 500-1000ms to optimize resources; it's not a deal of not being good enough for me, it's just a suggestion you can take or leave.

That wasn't what I meant. I'll take it to heart and try to optimize it. As I said, I'm still learning and don't know everything yet, and this is my first attempt at a PR. When I get home, I'll try to implement it, so there's a one-time delay. You're right that once the action is completed, no further updates are necessary.

@Nyr97

I have now revised it and would like to submit it as is.

#include "ScriptMgr.h" #include "Creature.h" #include "SpellInfo.h" #include "Unit.h" #include "Player.h" #include "ScriptedCreature.h" enum { SPELL_TRIGGER_ID = 52390, NPC_ENTRY_CONTROLLED = 28805, QUEST_ID = 12686, SPELL_CAST = 50361, EVENT_CAST_SPELL = 1, EVENT_CONTROL_CHECK = 2, }; class npc_servant_of_drakuru : public CreatureScript { public: npc_servant_of_drakuru() : CreatureScript("npc_servant_of_drakuru") {} struct npc_servant_of_drakuruAI : public ScriptedAI { npc_servant_of_drakuruAI(Creature* creature): ScriptedAI(creature), _controller(nullptr), _controlled(false) { } void JustEngagedWith(Unit* /*who*/) override { _events.Reset(); _events.ScheduleEvent(EVENT_CAST_SPELL, 4s); _events.ScheduleEvent(EVENT_CONTROL_CHECK, 1s); } void SpellHit(WorldObject* caster, SpellInfo const* spell) override { if (spell->Id == SPELL_TRIGGER_ID) { if (Player* player = caster->ToPlayer()) { if (player->GetQuestStatus(QUEST_ID) == QUEST_STATUS_INCOMPLETE) { _controller = player; Talk(0); me->UpdateEntry(NPC_ENTRY_CONTROLLED); me->SetHealth(me->GetMaxHealth()); _controlled = true; } } } } void UpdateAI(uint32 diff) override { _events.Update(diff); while (uint32 eventId = _events.ExecuteEvent()) { switch (eventId) { case EVENT_CAST_SPELL: if (!_controlled) { if (Unit* target = me->GetVictim()) me->CastSpell(target, SPELL_CAST, true); } _events.ScheduleEvent(EVENT_CAST_SPELL, 12s, 14s); break; case EVENT_CONTROL_CHECK: if (_controlled) { if (me->GetCharmerOrOwner() != _controller) { if (_controller && _controller->GetQuestStatus(QUEST_ID) == QUEST_STATUS_INCOMPLETE) me->DespawnOrUnsummon(1s, 3s); _controlled = false; _controller = nullptr; _events.Reset(); return; } } _events.ScheduleEvent(EVENT_CONTROL_CHECK, 1s); break; } } if (!_controlled) ScriptedAI::UpdateAI(diff); } private: EventMap _events; Player* _controller; bool _controlled; }; CreatureAI* GetAI(Creature* creature) const override { return new npc_servant_of_drakuruAI(creature); } }; void AddSC_npc_servant_of_drakuru() { new npc_servant_of_drakuru(); }

Code optimization and I hope it's ok this time ^^

you may want to put sql code in a file inside 3.3.5 update path too.

Thor1423 · 2025-08-06T09:58:17Z

Do I have to send it separately as a PR?

CraftedRO · 2025-08-06T10:03:37Z

separate file, in same PR, you can temporary name it 2025_99_99_99_world.sql

Thor1423 · 2025-08-06T10:07:16Z

Okay, I'll give it a try ^^
Have you tested the script?

+        GetHitCreature()->CastSpell(GetCaster(), SPELL_HEALING_WINDS, true); // Healing Winds


Suggested change

if (GetHitCreature()->GetEntry() == NPC_STORM_CLOUD) // Storm Cloud

GetHitCreature()->CastSpell(GetCaster(), SPELL_HEALING_WINDS, true); // Healing Winds

if (GetHitCreature()->GetEntry() == NPC_STORM_CLOUD) // Storm Cloud

GetHitCreature()->CastSpell(GetCaster(), SPELL_HEALING_WINDS, true); // Healing Winds

Isnt here missing space ?

Apparently, reading the comments here, they don't want my fixes.

It was worth a try.
