Who is attacking me?

[Viano]

Hi everyone,

how do you detect whether a mob is attacking you? When I just read the mob's target, sometimes mobs are targeting me without attacking and sometimes players do target me without attacking either.

Is there some flag like isInFightWithGuid?

There's probably a better way to do it, but what I do is monitoring my Health all the time. Then, in a Timer, I got a procedure that looks like this:

if myHealth < myMaxHealth then

    //I lost some health, is someone attacking me or a priest buffed me ?
    tempHealth = myHealth

    if myHealth < tempHealth then  //there's definitly something wrong

         attack()

    End if

End if

It's not the real code, but it's pretty self explanary and it's the way I do it. It's working, but you have to take some damage before to fight back, wich is obviously, not the best method...

So if a debuff taking your health is on your toon after a fight you think you are beeing attacked?

That would explain a lot of things ... lol

You are right, I even didn't think about it.

here is lua code, the one i am using

function _validEnemy(u)
local rc
rc = UnitExists(u) ;
rc = rc and not UnitIsDeadOrGhost(u) ;
rc = rc and UnitCanAttack("player", u) ;
rc = rc and not UnitIsPlayer(u) ;
rc = rc and (not UnitIsTapped(u) or (UnitIsTapped(u) and UnitIsTappedByPlayer(u)))
rc = rc and ( UnitAffectingCombat(u) or ( not UnitAffectingCombat(u) and UnitName(u .. "target") == UnitName("player")))
return rc
end

Hi

One simple solution would be to check if you are in combat.
if you are in combat scan nearby mobs. If any mob is targeting you ..

you can be fairly sure he is attacking you. :P

return rc
end

Ok, that would probably work but looks like an overkill. Thank you.
What parameter is u? Is it the Guid?

That is not a solution because players and mobs are sometimes targeting me without fighting with me.

u - is standard wow unit, like "target", "focus" etc....

in that case i am using "EnumVisibleObjects" with calllback like this one

function enumCallback(hguid, lguid)
_SetFocus(hguid, lguid)
if ( _validEnemy("focus") ) then <we found enemy who is attacking us or we can attack>; SetTarget(hguid, lguid); end
end

end

I take it EnumVisibleObjects is a function you are calling via injection? Do you think this is available as a flag for those who only do memory reading?

why not ? there are tons of examples on this forum how to iterate over object list out of proc and execute lua string

pseudo code

notfound = true ;
object = ObjectList ;
targetguid = 0 ;
while (object && targetguid == 0)
{
guid = object.guid
setfocus(guid)
rc = lua_doString("IsEnemy(\"focus\")") ;
if ( rc ) targetguid = guid ;
object = getnextobject ;
}
if ( targetguid )
here is our enemy

something like that...

How do you use lua_doString out of process?

Asm. Lots of my noobish posts in this forum

Well, fasm_managed uses CreateRemoteThread to execute the ASM, so it's not completely out of process.
Might be the only possible way to use the ASM though

Ok, the easiest way to achieve this is comparing whether a mob is in combat and has me as target.

// IsAttackingMe ripped of from BabBot
Convert.ToBoolean((ReadDescriptor<uint>(Constants.UnitFields.UNIT_FIELD_FLAGS) >> 0x13) & 1);

if you solo - yes (there are some exception though, rare one). if you in group - mob may not attack you )
