- 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.
(cherry picked from commit 532ab1c7f8)
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
(cherry picked from commit d507a7e338)
* 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)
- There's still an overload allowing for x, y, z, o to be passed directly
- Fixed default animstate for GameObject creation in many places, it should be 255, not 100 (checked in sniffs)
