I'm trying to find where the start of the function:
IDirect3D9::CreateDevice, then i will use the method IDirect3DDevice9::EndScene (which i also need to find), for making an in-game trainer menu, which i am coding it using ASM.


So, after calling the d3d9.dll function Direct3DCreate9(D3D_SDK_VERSION), i can sucessfully get the VMT for the current process, and looking at the pointer given(in cheat engine) i see the data as in the picture.

my question is, which one of those valid pointers is the address of IDirect3D9::CreateDevice and IDirect3DDevice9::EndScene ??

and my second question: do i need to call CreateDevice in order to access EndScene address?

If I were you I'd skip all that fiddling with the addresses and offsets and just use an AOB scan for the two function you want to hook.
Every time I made an EndScene hook I did it like that.

But notice that the patterns might change with dx9,10,11, 11.1

Maybe you can get the pattern/address by letting ce hook direct x for you and output the address with lua.

You don't have to call any of them first to be able to hook them.
But of course you have to "continue" your hook in the original function or else the original function will never be called, but I think you know that.

what are the byte pattenrs to search for using AOB ? (using DX9)
or how can i use LUA to get the addresses(never used LUA in CE).

For Direct3D VTables, just count the position that they are in the header.
For example, open up d3d9.h and locate the IDirect3DDevice9 interface:
Code:

The index in the vtable starts at 0 so QueryInterface would be index 0.

Following that suite, we have important calls like:
- Reset = 16
- Present = 17
- BeginScene = 41
- EndScene = 42

Given that the vtable is a list of pointers, if you want to read/write to the proper index, you can either use something like:
offset = (vtable + (index * 4));

Or if you cast as a unsigned int array you can just directly index with the above values.
