Hi Razzue, How to read other players' names? I read other threads and you mentioned it should be read in the name cache. Is it the address [Base + Object_Manager.Names]. I read this address and find it is a pointer to other pointers but I can't find any names.

I'm also interested in this question, I think it has something to do with the GUID

this is how it was done on 3,3,5

char* PlayerObject::GetName()
{
	char* Wname[12];
	unsigned long mask, base_, offset, current, shortGUID, testGUID;
	mask = WowMemory->ReadUint(nameStore + nameMask);
	base_ = WowMemory->ReadUint(nameStore + nameBase);
	shortGUID = this->GetGuid() & 0xffffffff;
	offset = 12 * (mask & shortGUID);
	current = WowMemory->ReadUint(base_ + offset + 8);
	offset = WowMemory->ReadUint(base_ + offset);
		if ((current & 0x1) == 0x1) { return "error1"; }
	testGUID = WowMemory->ReadUint(current);

	while (testGUID != shortGUID)
	{
		current = WowMemory->ReadUint(current + offset + 4);

		if ((current & 0x1) == 0x1) { return "error1"; }
		testGUID = WowMemory->ReadUint(current);
	}
	return encode(WowMemory->ReadCStr(current + nameString,12),12);
}

I think it's something like this too
I would like to understand how to do this in the current version

[Razzue]

Compiled your project, thank you very much, everything works
I will try to compile the dumper now

You shouldn't need to compile namreebs unpacker, if you check out the release tags there should be pre-compiled versions that still work fine

For Nam's unpacker all you gotta do is drop wow's .exe onto the unpackers .exe, and wait for it to work it's magic

As for player name cache, it's actually very similar to reading the object manager externally (though again, I'm sure there's a few ways to go about it)

[Hrap]

Thanks I found the compiled version, I will test it, everything turned out to be much easier than I expected, thanks a lot

[tommingc]

@Razzue, thanks for the continuous post of the offsets!


@Hrap Just FYI, I'm using a tough way to do this(under c#), Really do not suggest creating a thread for every name call. I believe there is an easier way to do this, but as I just started, I will leave it as this for now until some bro tells me a better way.

Fantastic!! Thanks, Razzue.

Thanks a lot , Razzue.

Greetings, Razzue
Such a question, what are the possible options for clicking on an object?
For example, while fishing, in what way is it possible to click on the float
Perhaps you, as a more experienced one, have already encountered this

[Hrap]

I believe it can be calculated.
Let's say I know the position and tilt of the camera and the position of the float object, I think, given the perspective, it is possible to calculate which point on the screen to click to get into the game on the float

But it's quite difficult, it seems to me, maybe there is an easier way, because the game calculates all this?

Just use OpenGL or DirectX WorldToScreen, you can easily find how to do it in google.
here's how i do it with dx

   var proj = Matrix.PerspectiveFovRH(Fov * 0.6f, aspect, nearClip, farClip);
            var eye = new SharpDX.Vector3(cameraPos.X, cameraPos.Y, cameraPos.Z);
            var lookAt = new SharpDX.Vector3(cameraPos.X + m[0, 0], cameraPos.Y + m[0, 1], cameraPos.Z + m[0, 2]);
            var up = new SharpDX.Vector3(0f, 0f, 1f);
            var View = Matrix.LookAtRH(eye, lookAt, up);
            var inPos = new SharpDX.Vector3(pos.X, pos.Y, pos.Z);
            var outValue = SharpDX.Vector3.Project(inPos, bounds.X, bounds.Y, bounds.Width, bounds.Height, 
                nearClip, farClip, Matrix.Identity * View * proj);
            if (!bounds.Contains((int)outValue.X, (int)outValue.Y))
            {
                return System.Numerics.Vector2.Zero;
            }
            return new System.Numerics.Vector2(outValue.X, outValue.Y);

            }
            return new System.Numerics.Vector2(outValue.X, outValue.Y);

Thanks,
Will this work from external applications without intercepting Directx functions?

[Razzue]

Why click? Just write a unit/objects guid to your mouse over GUID, then send the key bound to interact with mouse over, ezpz

[Hrap]

As an option)

But a couple of questions arise
How safe it is to write to the game's memory.
And is there a game memory protection against such actions?

[tommingc]

or you can also createremotethread to do the interact action, but it still requires writeprocessmemory..

[Hrap]

the fact is that I want to avoid writing to the process memory as much as possible

Previously, for the exact rotation of the player, I recorded the angle of rotation I needed in Player.position.rotation
and this once led to a ban (though on a private server)
now I do everything by sending keystrokes.
It's not as accurate, but it works.
