- Decoupled Unit logic: split of spell critical chance into done (caster bonuses) and taken (target bonuses), this allows to precalculate caster bonuses on aura apply and then check victim's auras on damage/healing calc
- Made static a bunch of methods (they no longer have this pointer because they are now called from periodic handlers which may or may not have an active caster in world)
- Simplified all AuraEffect bonuses into AuraEffect::_amount, no more duplicated code
- Critical chance and whether or not caster is player owned unit (for resilience calcs) is now saved one level upper, on Aura itself (it's impossible as of 3.3.5 to have different effects with different critical chances)
- Minor cleanup of SPELL_DAMAGE_CLASS_NONE and Arcane Potency (#18813) crit handling
Closes#19876
- PvE combat is now always mutual. UNIT_FLAG_IN_COMBAT is backed by actual references to the units we're in combat with.
- PvP combat is now also tracked, and almost always mutual; spells like Vanish and Feign Death can break this rule. That means we can easily determine a list of players we're fighting.
- By extension, IsInCombatWith now has sensible behavior when invoked on nonplayers.
- Threat and combat systems are no longer the same.
- They still have an enforced relationship (threat implies combat - clearing combat clears threat)...
- ...but we can have combat without threat. A creature (with threat list) isn't considered to be engaged until it has an entry on its threat list...
- ...which means we can now faithfully replicate retail engage behavior. Combat on projectile launch - engagement start on projectile impact. Yay for progress!
- AI method refactor, as already ported in 6113b9d - `JustEngagedWith`, `JustEnteredCombat` and `JustExitedCombat`.
- Vehicle threat is now properly pooled on the main vehicle body (fixes#16542).
- Various edge case bug fixes for threat redirects (Misdirection "cancelling" Vigilance and similar).
- Target re-selection is now significantly faster.
- Fixed a ton of other smaller edge case bugs, probably.
Closes#7951 and #19998.
- m_currentSpells and spell would be different in case cancelation of a channeled spell would remove the aura, and aura scripted to cast another channeled spell on remove
- In the above situation, we would lose reference of currentSpell and remove reference from wrong one, this was fixed by clearing the pointer before spell cancelation.
Closes#20172
Core/Spell: The giant CastSpell unclusterfucking (that's a word now) of this generation.
- CastSpell now always takes three arguments - target, spellId, and a struct containing extra arguments
- This struct (CastSpellExtraArgs, see SpellDefines.h) serves as a conglomerate of every previous combination of the 20 billion different CastSpell overloads, all merged into one
- It has some great utility constructors - check them out! All of these can be used to implicitly construct the ExtraArgs object.
- A gajillion refactors to make everything behave the way it always has
* Core/Entities: Fix some weird movement due to los issues
- Made LoS check use collisionHeight instead of midsection. Value was too low.
- Gnomes will now have a breath bar more quickly than for example a tauren.
- Changes have been made to checking for ground z as well, some tweeking might be needed but removed most of the scattered +2.0f/+0.5f/we
* Add 0.05f to isInAir check in Creature::UpdateMovementFlags
* Core/Scripts: Rewrite Boss Kalecgos (Sunwell Plateau)
Scripted all spells
Corrected behavior of Spectral Blast and Curse of Boundless Agony
Removed wrong wipe behavior
Fix problem where bosses would be stuck with banish
Added Boundaries
Corrected texts
Removed old hacks
Other minor fixes
* Combat/Threat rewrite (PR #19930) prep work. Mostly refactors, and a compatibility layer on ThreatManager/HostileReference that allows scripts to be changed already.
Then it turned out that gameobject LoS is already fixed. So all this does, really, is restructure some stuff.
And remove the hack from Sapphiron because I could.
* 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
* 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.
- Actions will not be dependent on processing moment
- Increased GameObjects cooldown resolution to milliseconds, fixes arming time of traps to be exactly one second and not something from range (1000, 1999)
