* Online states are now re-evaluated before victim update instead of continuously. Closes#22226. Tagging #21501.
* Victim update now happens every 1s as opposed to every server tick unless current target goes away.
* Suppressed threat is no longer re-established until the victim gains additional threat (by hitting the target, for instance).
* Assistance threat is now split between non-controlled units threatened by target, as opposed to all units threatened by target.
Fix crash happening when a disabled quest was added and rewarded (through a GM command). Disabled quests are not validated on startup and they can reference invalid spells.
- ScalingStatDistribution/Value (ie heirlooms): apply bonuses in all cases, some calls used nullptr (like after disarm) and item wasn't regaining them
- AP multiplier wasn't correctly reflected after unequipping a weapon
- Correctly set base damages at unequip
Closes#21610
Core/Misc: Added helper function Unit::SetFullPower
Cherry-picked from 8199eef81c
Core/Creatures: Updated power type handling (#20981)
Cherry-picked from 16a7a414ab
- AI hook will now receive the result by copy, as modifying it had no effect
- Some renaming: result->spellClickHandled, clickPair is actually clickBounds, the clickPair is the pair <creatureID, SpellClickInfo>
- Added new UNIT_STATE_FOCUSING for creature focus system, this will stop creatures adding/clearing the UNIT_STATE_CANNOT_TURN mask (eg UNIT_STATE_STUNNED if stunned while focusing a spell)
- Added UNIT_STATE_CHARMED that gets set/removed on any charm type (UNIT_STATE_POSSESSED is only for possess as it's name suggests)
- The new states are checked against mask to know whenever client needs to regain character control
Closes and fixes#21460
- Only one charged mod will be consumed per SpellMod apply, and it'll be compared against other mod priority
- This is proper way of handling Backdraft/Backlash and Deathchill/Killing Machine
Thanks to killerwife for info
- Fixed correct Retaliation damage spell according to sniffs is 20240
- CalcArmorReducedDamage insisted on dealing a minimum of 1 damage even if damage was 0
- CalculateDamage was zero-phobic too: it defaulted to arbitrary max 5 damage
Closes#19081
- 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.
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
- Use Midsection height for LoS checking.
- Changed MotionMaster::MoveJumpTo to use correct z. This change also makes sure the _owner will jump towards the given angle. Instead of jumping to a unintended angle if the first one is not in LoS.
