- Triggers can no longer have a threat list (this may expose some ugliness in old legacy scripts)
- Threat entries are forced to OFFLINE if the AI refuses to attack the target
- Clean up passive creature evade behavior to be more consistent
- Fix a months old issue in spawn group management that would cause "Inactive" to incorrectly show in .list respawns for system groups outside of map 0
- Valithria script cleanups, remove old hacks and make it work with the new system. Closes#21174.
- Some strings cleanup
- 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.
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;
* Combat/Threat rewrite (PR #19930) prep work. Mostly refactors, and a compatibility layer on ThreatManager/HostileReference that allows scripts to be changed already.
* 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.
- Added an auxiliary function IsInBounds to base CreatureAI
- Changed container to vector. Set had no sense because we're storing new pointers, they have different addresses even if the boundary is the same
Movement/SplineChain: Bump value range for DB chainId up to uint16 (0 to 65535) from uint8 (0 to 255). Turns out sniffs generate far more chains than I expected.
- Default range for DoZoneInCombat: 50.0f -> 250.0f.
- Add optional second arg to SummonList::DoZoneInCombat to specify range.
- Also a bunch of random NULL -> nullptr cleanup.
- When a creature cannot find a path to its victim, it begins evading all attacks and regenerating health.
- If this persists for 5 seconds, it evades back to spawn position with new EvadeReason value EVADE_REASON_NO_PATH.
- Also some SmartAI cleanup (why oh why does it have so much duplicated code) and getting rid of #defines in favor of type-checked compile-time constants.
- Add missing const attribute on CheckBoundary arg.
- Prevent AI from attacking a target that is out of bounds. This prevents exploids such as killing Gluth/Deathbringer from out of bounds.
- Fixes creatures turning just before a spellcast finishes and smacking players with supposedly-unavoidable damage. Fixes and closes#15393, #10803, and probably others.
- Fixes visual effects not lining up with the correct target for spells that have their visual aligned with the caster's orientation (examples: Anub'rekhan Impale, Ingvar's Smash/Dark Smash, etc.). Fixes and closes#2947 and probably a bunch of others, including the aforementioned #15393 and #10803.
- Creatures' displayed target now properly matches the unit they are targeting with spells for a split second (blizzlike). This is necessary to get proper client-side orientation.
- Migrate boundary logic to Maps/AreaBoundary instead of having it sit in InstanceScript (to possibly allow use for other purposes).
- Implement the first five boundary types in Maps/AreaBoundary.cpp.
- Add boundary checks to Creature's update logic
- Add boundary data for all Northrend raids
- Add boundary initialization structures and methods to InstanceScript
- Modify EnterEvadeMode signature. It now passes a value from the EvadeReason enum as parameter to allow special casing depending on evade reason
- Remove previous (weird) boundary code that had them linked to GO spawns
- Combat no longer removes stealth, only damage does
- Creatures will pursue a stealthed unit they cannot see if they're already in combat with them
- When a player is ~~3 yards~~ 8% + 1.5 yards away from the usual stealth detection distance, the creature will perform the "alerted" effect.
- When sitting/sleeping creatures are distracted or alerted, they will stand up
- Idle movement creatures will return to their original (spawn) orientation after distract/alert
- When entering combat with a distracted/alerted creature, distract state is removed
- NPC no longer have a limit to stealth visibility (granted by stealth modifier spells/buffs)
- If alert visibility is greater than aggro range, no alert sent
Update Position::GetPosition() and similar methods signatures to reflect 2a4c9bcaf9 changes by return a Position object instead of accepting a Position parameter by reference.
* Moved everything into one specialized method instead of being scattered all over the place
* Allow localizing creature names in chat messages (when using $N)
* Send SMSG_GM_MESSAGECHAT for gm messages
