Player IsInCombat?

[xLeo123]

Is there an address/offset to check if our player is currently in combat?
Apart from going through all objects and checking if the target is equal to our GUID is there any way to just read a memory location to see if our current player is in combat?

I've tried reversing some lua functions such as IsAffectingCombat, and InCombatLockdown, none have been any help to me..
I've also tried reading from (PlayerBase+UNIT_OFFSET_FIELDS)+0x30, actually i've tried literally every offset from UNIT_OFFSET_FIELDS and none change when im in combat. and +0x30 & 0x80000 returns true even when im not in combat, was that method changed recently?

Thanks,
Leo

int __cdecl lua_UnitAffectingCombat(int pLuaState)
{
  int result; // eax@2
  int v2; // ST10_4@2
  int pUnit; // eax@3
  char *pUnitName; // eax@3

  if ( FrameScript__IsString(pLuaState, 1) )
  {
    pUnitName = FrameScript_ToLString(pLuaState, 1, 0);
    pUnit = GetUnitFromName(pUnitName);
    if ( pUnit && (*(_DWORD *)(*(_DWORD *)(pUnit + 208) + 208) >> 19) & 1 )
    {
      FrameScript_PushNumber(pLuaState, 1.0);
      result = 1;
    }
    else
    {
      FrameScript_pushnil(pLuaState);
      result = 1;
    }
  }
  else
  {
    FrameScript_DisplayError(pLuaState, "Usage: UnitAffectingCombat(\"unit\")", v2);
    result = 0;
  }
  return result;
}

Thanks, by the way how did you get Hex Rays to look so nice?
Mine gives me hard-to-read output such as:

 v4 = (char *)sub_826B90(a1, 1, 0);
    v3 = sub_5A2670(v4);
    if ( v3 && (*(_DWORD *)(*(_DWORD *)(v3 + 208) + 208) >> 19) & 1 )

(and yes, the wrong offset in this case.. any idea why?)

[Kryso]

Use "rename" and "set type" button when you find out what variable or function does And wich wrong offsets do you mean? [ [ unitBase + 208 ] + 208 ] is correct offset for flags and ( flags >> 19 ) & 1 is correct flag for combat.

Yup, strange, [[UnitBase+52]+208] also works for me o.o :P

You can make it even nicer:

signed int __cdecl Lua_UnitAffectingCombat(int luaState)
{
  signed int result; // eax@2
  int v2; // ST10_4@2
  CGUnit_C *pUnit; // eax@3
  char *unitName; // eax@3

  if ( FrameScript__IsString(luaState, 1) )
  {
      unitName = FrameScript_ToLString(luaState, 1, 0);
      pUnit = GetUnitFromName(unitName);
      if ( pUnit && (pUnit->unitFields->UNIT_FIELD_FLAGS >> 19) & 1 )
      {
          FrameScript_PushNumber(luaState, 1.0);
          result = 1;
      }
      else
      {
          FrameScript_pushnil(luaState);
          result = 1;
      }
  }
  else
  {
      FrameScript_DisplayError(luaState, "Usage: UnitAffectingCombat(\"unit\")", v2);
      result = 0;
  }
  return result;
}

208/4=52 o_O

TOM_RUS, did you buy the latest HexRays with fpu-support?
God, I am still hoping to win money or finally finding a cracked version, reversing functions making much use of fpu-instructions is messed up with HexRays 1.0 and it is just too expensive for me...
Too bad I got used to the fast reversing speed with HexRays, reading large amounts of "raw" ASM is just time-ineffective compared to HexRays :/

There's latest IDA with latest Hex-rays available for free on internet. Click here to find one :P

Actually the latest is 5.6.

[TOM_RUS]

Actually the latest is 5.6.

Hmm, yes, released 2 weeks ago. I haven't noticed that.

Probably because you pirated it so you don't get the email notifications.

If you can use LUA...

API InCombatLockdown - WoWWiki - Your guide to the World of Warcraft

[WannaBeProgrammer]

InCombatLockdown()

Notes

* This function starts to return 1 after event "PLAYER_REGEN_DISABLED" has been fired.
* Returns nil once again once event "PLAYER_REGEN_ENABLED" has been fired.

You can also read PLAYER_REGEN_ENABLED & PLAYER_REGEN_DISABLED.
