* Properly restore react state after possession expires. Closes#20769.
* Possessed creatures now don't override player control with random/waypoint motion
* SmartAI creatures now properly re-aggress charmer after charm expires
* 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.
The number of edge cases in which weirdness is seen on "effect movements" will be kinda reduced, plus consistency, plus movementInform on custom movement spline initalizations.
- Chase to angle is now functional. Pets use this to chase behind the target. Closes#19925.
- Chase to arbitrary range interval works. Not used anywhere, but you can technically make hunter-like mobs.
- Pets now follow the hunter cleanly and without stutter stepping. Also fix some other things. Closes#8924.
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
- Spell bonus calculation and penalty was done twice, but it's simply flat +SP, which should be taken into account before other bonuses
- Fixed missing code from SpellDamageBonusDone/SpellHealingBonusDone and killed multiplication by stack amount twice for default coefficient spells (already multiplied on level penalty)
