[HELP] cant get Obj->Interact() to work.

[cenron]

I have managed to get all the other functions working except for Interact(). I have no idea why this works for others but not me.

Its function34, as specified by Cypher.

    virtual void Function32() = 0;
    virtual void Function33() = 0;
public:
    virtual void Interact() = 0;                    // Function34
private:
	virtual void Function35() = 0;
    virtual void Function36() = 0;

and I have it declared like this.

m_pCurMgr =  (CGCurMgr_C*)( dwCurMgr );

and I call it like this

If(TargetObj)
   TargetObj->Interact();

I have no idea what I am doing wrong here. Any guidance would be appreciated.

Its function 36 currently. You must have outdated information, or have missed my correction. Apologies if I didn't apply the correction to the original post but there are countless threads about it.

Thanks for the correction. I must have missed the update.

But its still no go. This is so weird.

GetObjectName works great. It cant be an alignment issue?

    virtual void Function34() = 0;                    // Function34
	virtual void Function35() = 0;
public:
    virtual void Interact() = 0;					 // Function36
private:
    virtual void Function37() = 0;
    virtual void Function38() = 0;

@cenron:

I had the same problem.
Read this: http://www.mmowned.com/forums/wow-me...ways-null.html

GetObjectByGUID references s_curMgr via the Thread Local Storage. If you want to use GetObjectByGUID, you have two options.

1) Call it from WoW's main thread.
2) Set the value of your TLS variable, index 0 to the s_curMgr pointer.

As i solved the problem with GetObjectByGUID, Object->Interact works too.

I dont know if this would apply to me. I use the g_clientConnection method and dump the VTable into my own VTable. I also inject, I dont read process memory.

cenron, do any of the Virtual Funktions work for you?
If not it might be a compiler issue

Ya, all the other functions work. I am using GetPostion() // Function 8

and I am using GetObjectName() // Function 47

But Interact() // Function 36 dosen't seem to work for me.

I get the curMgr from [[g_clientConnection] + OFFSET]

// Pseudo Code
CGCurMgr_C *curMgr = (CGCurMgr_C *)[[g_clientConnection] + OFFSET]

CGObject_C * PlayerObj = GetObjectByGUID(curMgr->wLocal)

if(PlayerObj)
{
  CGObject_C * TargetObj = GetObjectByGUID(PlayerObj->GetKnownField(TARGET_DESCRIPTOR))

if(TargetObj)
   TargetObj->Interact();
}

This isnt exactly how my code look, I got wrappers which streamline the code, but thats how it works.

I even have ClickToMove turned on just in case I am to far away. I get nothing. It dosent crash or error in any way. It just does nothing.

I thought it might have been an alignment issue so I tested it by directly calling the function.

tyepdef void (* tInteract ) (void);
tInteract oInteract = (tInteract)((DWORD *)TargetObj + 4 * 36);

oInteact();

I still get nothing!

Here is an exact copy of my VTable. Maybe someone can see what I cant.

Sigh, did you even read what he quoted?

I see what your saying....I think.

dwCurMgr = [ [g_ClientConnection] + offset ]
m_pCurMgr =  (CGCurMgr_C*)( dwCurMgr );

DWORD* dwTemp = 0;

__asm
{
      mov eax, DWORD PTR FS:[0x2C]
      mov eax, DWORD PTR DS:[eax]
     mov pTmp, dwTemp
}

*(DWORD*)((DWORD)pTmp + 0x08) = dwCurMgrr;  // Has the TLS Slot changed?

EDIT: Never mind got it to work! The above code is valid. THX for the help man. Your the shit.

Where did you get that class for ObjectManager? I haven't seen any on these forums or on EoN. I haven't looked much at the ObjMgr part of WoW in IDA, I could probably figure it out. It'd be nice to share though.

Read the stickies.

[lanman92]

Okay, I can't figure out why this code is crashing WoW without even a message...

 
if(GetAsyncKeyState(VK_F11))
{
UpdateTLS();
curObj = (CGObject_C*)(s_curMgr + 0xAC);
MessageBox(NULL, L"1st curObj: " + (DWORD)&curObj, L"curObj", MB_OK);
while(curObj != 0)
{
if(curObj->GetObjectName() == "Young Thistle Boar")
{
MessageBox(NULL, L"We got the name right.", L"Yipee!", MB_OK);
curObj->Interact();
}
nextObj = curObj->m_nextObj;
curObj = nextObj;
Sleep(100);
}
//FreeLibrary(hThis);
exit = true;
return;
}

[Shynd]

Does it show the message box? And I do believe that you are comparing strings incorrectly.

[lanman92]

I was pretty sure that I was doing the strings wrong, don't I have to dereference it or something? The Messagebox doesn't show when I run it. I think it's in the part where I get the first object. It seems to crash right there.

[Cypher]

Rofl fail.

You can't compare C-style strings with the equality operator. Either use a C++-style string with the equality operator overloaded (ie std::string) or use the appropriate C function to do your string comparisons (strstr, stricmp, etc).

Protip: Learn the language before you try to use it, your code is ****ing retarded.
