Where to find SNO ID for an ACD?

[bad6oy30]

I'm in process, trying to call D3::GetSnoFromSNOId:
__thiscall (SNOGroup* this, int snoId, int flag)

But I'm getting GPF.

When I set a breakpoint on calls from the regular game client, I see a SNO group pointer that I recognize, but I can't recognize the snoId's being passed from anywhere. From the sources I've checked, it should be 0x90 bytes past the ACD pointer, but when I iterate all the ACD's, I don't find that snoID on any of them.

Just in case snoID has moved from ACD + 0x90, I tried this ACD struct:

struct ACDStruct
{
   int id_acd; // 0x000
   char name[128];	 // 0x004
   int val[147]; //0x84
};

... and I couldn't find the debugged sno ID in any val[] from any ACD

[iamclint]

hmm I believe the sno id you are looking for is at 0xb4?

[bad6oy30]

Ahhh... if I understand some other people's code I've been looking at, it looks like that's the ACD's SNO ID for the GameBalance SNO group.

So is the one at ACD+0x90 the SNO ID for the Actor SNO group? I thought there was one SNO ID per ACD that was used across all the SNO groups... is that wrong?

[iamclint]

appears to be at 0x90 based on darthons structs

   char name[128];             // 0x004
    DWORD unk_0;                // 0x084 
    DWORD id_unk1;              // 0x088 
    DWORD id_actor;             // 0x08C 
    DWORD id_sno;               // 0x090 
    char unknown_94[28];        // 0x094 
    DWORD gb_type;              // 0x0B0
    DWORD id_gb;                // 0x0B4

i'm just kind of shooting in the dark for you i only use the game balance id.

[bad6oy30]

Here's what I'm trying:

//GetSNOGroup is 0xe60350 @ 1.07a
//20 is GameBalance
void* snoGroupPtr = GetSNOGroup(20);
//GetSnoFromSNOId is 0xe7c400 @ 1.07a
//ACD.id_gb is at ACD+0xb4
void* itemGBSno = GetSnoFromSNOId(snoGroupPtr, acd->id_gb, 0);

But I find the returned itemGBSno is identical for a minor health potion, lesser health potion, and a gem.

There's a debug string being posted when this runs as well:
Trying to lock an invalid SNO {acd->id_gb} which doesn't exists or is not part of the GAMEBALANCE_SNO group

So is the one at ACD+0x90 the SNO ID for the Actor SNO group? I thought there was one SNO ID per ACD that was used across all the SNO groups... is that wrong?

Yes, ACD+0x90 is an ActorSNO id. ACD+0xB4 is a hash of gamebalance entity name. GetSnoFromSNOId won't work for this value because it really isn't a valid SNO id, You can try to use D3::GetGameBalance (0x00EA7E50 build 15295), but I never used it so can't help you.

[bad6oy30]

Does anyone have a signature for D3::GetGameBalance? I'm having a bugger of a time figuring it out.

[iamclint]

So it looks like GetGameBalance function is called with 2 flags first and 3rd argument
and the second argument seems to almost always appear to be an empty char for some reason.

  v4 = 2;
  a1 = 1;
  v1 = sub_EA7E50(&v4, &v6, &a1);

GetGameBalance appears that it is returning the gamebalance as a whole

what was you trying to do again?

0xecf830	D3::ACD::GetGBValueByGBId

I got lost trying to figure out what you are really after but if i'm right you want this ^ and this is how that is called ->

bool __cdecl sub_EE25C0(int a1, int a2)
{
  int v2; // edi@1
  int v4; // eax@3
  signed int v5; // ebx@4
  int v6; // eax@5

  v2 = *(_DWORD *)(a2 + 180);
  v5 = sub_ECF830(v2, a2)
}

So its pretty easy to tell from here that *(_DWORD *)(a2 + 180) is the pointer to the gbid so you can deduce down what the other argument is.

[bad6oy30]

I think what you've just posted is going to be what I need.

Just in case someone wants to know the GetGameBalance signature, arg1 is an 8-byte struct

struct ParamPair
{
   int gbSnoEntry;
   int gbId
}

__cdecl GetGameBalance(ParamPair*, void** snoPtrMaybe, bool* logIfNotFound)

snoPtrMaybe is a result of some sort, it's not read.
I don't know what the return value is, and I don't think I'll care once I study iamclint's last post

[bad6oy30]

Oh... I suppose the ACD structure

	char unknown_94[28];		// 0x094 
	DWORD gb_type;				// 0x0B0
	DWORD id_gb;				// 0x0B4  
	char unknown_B8[24];		// 0x0B8

is probably better expressed

	char unknown_94[28];		// 0x094 
	ParamPair snoGbId    //0x0B0
	char unknown_B8[24];		// 0x0B8

So the struct can be passed directly to GetGameBalance

[bad6oy30]

Ah, I see it now... GetGBValueByGBId only uses the "Items" section (2) of the GB data.

sub_EE25C0 confused me a bit... it's two ACD's.
