LUA function sorcery

[l0l1dk]

yes... and it works for player, target and etc. but for "pointed" units fail

Have you tried putting breakpoints in your detour and checking that all the values it's getting are correct?

[Wildbreath]

yes, all values correct. and before 7.0 it works correct :\
seems they changed something
after getting a GUID pointer, i writed new GUID to this pointer and return true. before 7.0 it works

This is why i used blizzard functions to do this. It works 100% of the time.

public void FromString(string guid)
{
        IntPtr unmanagedAddr = Marshal.AllocHGlobal(Marshal.SizeOf(this));
        Marshal.StructureToPtr(this, unmanagedAddr, false);
        Function<GetGUIDFromStringDelegate> internalFromString = Function<GetGUIDFromStringDelegate>.Create(Pointers64.Manager.GUIDFromString);
        internalFromString.Execute(unmanagedAddr, Marshal.StringToHGlobalAnsi(guid), 0x80);
        this =  (WowGuid)Marshal.PtrToStructure(unmanagedAddr, typeof(WowGuid));
}


[UnmanagedFunctionPointer(CallingConvention.ThisCall)]
private delegate void GetGUIDFromStringDelegate(IntPtr ptr,IntPtr guid,int unk);


//C++ tostring is all i have old bot but same
int toString(char *pGuidString)
    {
        typedef int (__thiscall *t_ToString) ( DWORD_PTR* pGUID, char *pGuidString, int unk );
        t_ToString ToString = reinterpret_cast<t_ToString>((DWORD_PTR)GetModuleHandle(NULL) + (WGUID_ToStringAddr - 0x140000000));
        return ToString((DWORD_PTR*)this,pGuidString,0x80);
    }

I don't have the offset anymore because I chenged the way my bot and lua work but this should solve your problem. These sigs should work on an old 6.x.x build x64 I think, maybe early 7.0 but i dont think so.

So question, assuming I'm trying to do this with VEH instead of inline hooking, on x64 I'd be setting RDX = pointer to unit's GUID and returning true? Still haven't quite gotten it working so I'd like to know if I'm at least on the right track.

[aeo]

One of my original posts has the HWBP(VEH) hook signature in it. No point in messing with registers as blackbone does all the work for you.

[uncledolan]

I can't get blackbone to work properly, tried to PM you but your inbox is full. Just stops calling my hook function and I haven't the slightest idea why.

Edit: Hooked function fires but not when I pass a custom string, only when it's player/target/etc. :gusta::gusta::gusta: As soon as I try a custom string it just stops working entirely.

Edit2: After maybe 50+ hours literally I got it working finally. Huge thanks to everyone who helped, I've been wanting to learn these things for a very long time and finally decided to dive in and it was amazing to be able to receive guidance from talented people.
