Kal C++ Functions

[Itutorial]

I am trying to figure out how these codes are used.

static int (__thiscall *CPlayer__FindItem)(void *thispointer, int a2, int a3) = (int (__thiscall*)(void *thispointerpointer, int a2, int a3))0x0045D1E0;


In this code it has int a2 and int a3

How can I tell what the a2/a3 stand for?

Is a2 the item the code will look for or is a3?

Any info helps guys please. I won't hoard my codes after you help me.

you cant tell anything from that. you need to look at the code to see how its used, or debug and check the value, or do both.

a2 is item index, a3 is quantity.
how to know? check function calls in IDA.

CPlayer::FindItem(a1, 653, 1)

in this case it's so obvious that a2 is index and a3 is quantity.

Regards.

Yes, I showed that method so it would be easier for everyone to understand what I was trying to say. Is there a list possibly that shows the values for each method?

Can anyone tell me why this doesn't work?

static int (__thiscall *CPlayer__FindItem)(void *thispointer, int a2, int a3) = (int (__thiscall*)(void *thispointerpointer, int a2, int a3))0x0045D1E0;

bool hasPickPet = false;

int pickpets[13] = {2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017};

int count;
for (count = 0; count <= 13; ++count); {
int pet = pickpets[count];
if (CPlayer__FindItem(pPlayer, pet, 1)) { <--- This part isn't working.
hasPickPet = true; }
}

you are using _FindItem @ 45D1E0 which is stdcall and not thiscall, you should be using FindItem @ 45D190.

Anyway you would be willing to go through some of this stuff with me? Maybe in PM.
