I've looked into how LoS works to fix guided arrow today (which I did manage to do, more on that at a later time). In the process I ran across the function that parses aurafilters, GA and many other skills use hardcoded aurafilters.
Here is what I managed to uncover and the parsing code (an identical copy of this code also exists inside D2Client.dll)
Code: Select all
L
1 1 1 FindPlayers
2 2 2 FindMonsters
3 4 4 FindOnlyUndead
4 8 8 FindMissiles (will not find missiles with 'explosion' set to true)
5 10 10 FindObjects
6 20 20 FindItems
8 80 80 target units flagged as IsAtt in monstats2
H
9 1 100 NotInsideTowns
10 2 200 UseLineOfSight
11 4 400 target units that are selectable (also checked by curse funcs manually)
13 10 1000 FindCorpses (of monsters and players)
14 20 2000 NotInsideTowns(B)
15 40 4000 IgnoreSpecialMonsters (those set to 'boss' in MonStats)
16 80 8000 IgnoreAllies? (will return true when the unit is not allied with the player)
17 1 10000 TargetAllies? (if the unit is set as 'npc' in MonStats it will be ignored)
18 2 20000 This is a very specific test, testing for tentacle1-3 for example
19 4 40000 IgnorePrimeEvils (those set to 'primeevil' in MonStats)
20 8 80000 IgnoreJustHitUnits (used by chainlightning, which sets state_JustHit on whatever it hits, and this prevents the same target from being picked twice)
[ flags 7, 12, and 21-32 are unused ]Slow Missiles - players, monsters, legaltargets, ignoretowns, legaltargets2, ignorespecial, ignoreallies,

Mind Blast & Blade Shield - players, monsters, legaltargets, ignoretowns, LoS, ignoreallies,
