Stack call

 	MQ2ItemDisplay.dll!ItemDisplayHook::SetSpell_Detour(int SpellID=58702816, bool HasSpellDescr=true, int unknown_int=0)  Line 622	C++

disassembly middle line was pointer

Code: Select all

0303FEF5  xor         eax,edx 
0303FEF7  sub         eax,edx 
0303FEF9  call        GetSpellByID (30336B0h) 
0303FEFE  mov         eax,dword ptr [eax+228h] 
0303FF04  mov         ecx,eax 
0303FF06  mov         dl,byte ptr [eax] 
0303FF08  inc         eax  

pointed code block from mq2utilities.cpp
line with "szBuff, GetSpellByID" is where the pointer was

Code: Select all

case 139: //limit spell this affects 
         strcat(szBuff, "Limit: Spell("); 
         // changed this case to work for any future changes by referencing 
         // the spell array for the name 
 >      strcat(szBuff, GetSpellByID(abs(pSpell->Base[i]))->Name); 
         if ( pSpell->Base[i] > 0 )  strcat(szBuff, " allowed"); 
         if ( pSpell->Base[i] < 0 )  strcat(szBuff, " excluded"); 
         strcat(szBuff, ")"); 
         break; 

If you need more Tell me where and how to get it for you.

What zip are you running and have you made any modifications to the source? IE this.

and no changes. kinda been trying to narrow it down. i can inspect some stuff but others I cannot. seems items with spell haste on them. and the cleric spell haste buff. also some older items with focus on them

Try that change by ieatacid and try to get it to crash again. If so, post another debug.

[georgesilver]

Same type of error. different place. Unless i edited something wrong.

Code: Select all

     if (pSpell->CastOnYou[0]) { 
02AB20D1  mov         eax,dword ptr [esp+10h] 
02AB20D5  mov         eax,dword ptr [eax+239h] 
02AB20DB  cmp         byte ptr [eax],0 
02AB20DE  je          $L87110+249h (2AB2128h) 
       sprintf(temp, "Cast on you: %s<br>", pSpell->CastOnYou); 
02AB20E0  push        eax

       sprintf(temp, "Cast on you: %s<br>", pSpell->CastOnYou); 
       strcat(out,temp); 
     }

New zip out.

[vzmule]

Holy shit. A bug report with debug spew? I just about fell out of my chair :)

[fearless]

I figured if I pasted the link on how to do it enough, somebody would finally step up.

[georgesilver]

Working great after the new .zip. Hopefully I can help again in the future.
