Today, we're moving UNIT_FLAG_IMMUNE_TO_PC and UNIT_FLAG_IMMUNE_TO_NPC to higher-level abstraction so combat manager can react to it.
New methods on Unit:
- void SetImmuneTo<All/PC/NPC>(apply, keepCombat = false);
- bool IsImmuneTo<All/PC/NPC>() const;
(cherry picked from commit 74af880217)
* Combat/Threat rewrite (PR #19930) prep work. Mostly refactors, and a compatibility layer on ThreatManager/HostileReference that allows scripts to be changed already.
(cherry picked from commit e2a1ccd118)
* Add new method Map::getFullVMapDataForPosition to get area info and liquid info in a single vmap lookup
* Use this lookup in Map:: relocation methods to update m_areaId and m_zoneId fields on WorldObject
* Adjust GetZoneId/GetAreaId on WorldObject to always return these cached fields
* Clean up liquid state handling on Unit and Player
* Hand floor's Z coord up through GetFullTerrainStatusForPosition, use it to update a new field in WorldObject, and use that to feed a new GetFloorZ call on WorldObject.
Closes#16489
(cherry picked from commit f6c849729b)
* Pet/Guardian AI hook re-organizing:
- Adjust OwnerAttacked/OwnerAttackedBy hooks on CreatureAI to fire for all owned units, not just player pets. This should allow guardians to more reliably recognize valid targets.
- Kill off the AttackedBy hook. While it was defined in CreatureAI.h as virtual, it was only ever invoked for player pets in specific situations. This makes it classic developer bait.
- Adjust PetAI to use DamageTaken instead of AttackedBy.
- Adjust behavior of AttackStart on PetAI to compensate.
(cherry picked from commit 1660bb7d27)
Fixes the following issues:
- Player pets would aggro neutral mobs as soon as they start autocasting (Imp's Firebolt) if they're in react range (due to victim != null, autocast counts as autoattack and sets victim)
- Neutral mobs would randomly evade when aggro switched between targets.
Closes#19768, #19485 and #10921.
(from PR #19814)
(cherry picked from commit 69fd6245dc)
- Creatures should no longer get stuck in evade mode following a target if a spell hits the creature just as it's entering evade mode.
- Fixes and closes#4943. Finally.
(cherry picked from commit 1945874f96)
- Update clients whenever target has more than one application of an aura that applies such aurastate
- Update again when one application gets removed
- Fixed Fire and Brimstone computing damage if any warlock applied the Immolate (should only count for own)
Closes#19790
(cherry picked from commit e27c385b48)
After discussion we realized, ariel and me, that Creature and Unit IsMovementPreventedByCasting() have not the same checks (order matters)
(cherry picked from commit 5a2f0ce29e)
- IsFocusing is made virtual again, so there's no need to keep a duplicated function
This reverts commit 5043639c56.
(cherry picked from commit 3ea46e57af)
Set in front modifies only the serverside orientation, use with care.
Also check for current focus to prevent things like incorrect damage on casting creatures (ie dragon breath direction change in your face because of some taunt missclick)
(cherry picked from commit 229444b74a)
- This commit enables stack rule 3 to be properly used to fix auras that should be active but only one providing effects, even if the spell has multiple auras
Closes#19454
(cherry picked from commit 9900899dd9)
- Rather update normal instance reset time to 2 hours after last creature kill
- This fixes yet another integer overflow due to the possibility of having time_t max showing up
- Also change respawntime and resettime fields to bigint on respawn/instance related tables
- Start using prepared statements on the InstanceSaveMgr
(cherry picked from commit 4c593f12ca)
- Removed Unit::GetUnitMeleeSkill as it was basically a copy of GetMaxSkillValueForLevel
- Removed static from GetEffectiveResistChance, as this was passed anyways, changed name to CalculateAverageResistReduction, which better reflects what it does
- Fix melee miss chances calculated from attacker maxskill instead of victim maxskill
- Do actual checks if spell can be resisted/missed in MagicSpellHitResult (ie chances > 0)
- Fixed SPELLMOD_RESIST_MISS_CHANCE calculation in MeleeSpellMissChance
- Minor codestyle and cleanup of diminishing returns calcs
(cherry picked from commit e565b34f6d)
- Splitted containers for flat modifiers and pct modifiers, as they now have different handling
- Amount is now multiplied only on apply; on unapply, iterate through auras and reset the counter
- Fixes many cases of rounding error due to applying/unapplying of small factors
- Allows amounts to be zeroed (ie with an AuraEffect of amount -100)
- Do a partial revert of 6dc37a9add, auras should update amounts only for items allowed (ie no more giving crit to a sword while having an axe in the other hand and being Poleaxe spec'd)
- SPELL_AURA_MOD_SCALE now scales additively, rather than multiplicatively (checked in sniffs)
Closes#18687
(cherry picked from commit c69a7d1223)
