Trying to learn a few things here, and I'm not quite sure on how to find the AOB/address that would let me turn on a name tag hack for a shooting game.

I've done the easy stuff, unlimited ammo, no reload, no-spread, etc. Now I'm looking into creating D3D hacks but I don't know where to start.

You might wanna look up some DirectX, more specifically the DX that the game uses. Finding the AOB of things is just taking the Hex (Bytes) of the instructions and copying them down. If there are values or immidiate data in the instruction then you should wild card as it is bound to change.

For example:

Instruction:
CALL 401000

AOB:
E8 ?? ?? ?? ?? (Where ?? is a wild card as the relevant data is prone to change in future releases).

Edit:
If you want to have a AOB for lets say a pointer, then you must find where that data is accessed in memory and then do the same (copy the bytes and wild card the current pointer address)

How would I find the correct instructions?

I know I am looking for a conditional jump that compares my team with the other players team. If we are on the same team, it jumps to showing the name tag. If not, it doesn't.

But I don't know how I would find that.

Perhaps, find the address of a teammate's name, and the address of an opponent's. Then find out what accesses these addresses, find the piece of code accessing your teammate's name and not your opponent's. Then backtrace.

I've been having trouble with this. I get about 10 addresses per name, and it's tough to figure out which ones are the correct ones. I can see how some of the addresses are similar, but I still have no idea which pair.
