Find Object Manager in 3D Games

[abystus]

I've always been able to find the player structure along with enemy structures in 3D games (this is very easy), but am not familiar with a good method to retrieve the object manager address. Is there a way to backtrack from the base address of the player structure to find the object manager, or an easier way entirely? I'm looking for a general purpose method as the games I usually fool with aren't the mainstream ones that everyone hacks, so I would only need an overview of a method versus exact details for a specific game. Any help would be appreciated.

Find 2 mobs close to you, find their names or health or something, subtract addresses to get possible unit struct size, find hp, use cheat engine what writes to this, look at assembly, put breakpoint etc, learn about stack frames in functions, base pointer, stack pointer, find offsets that way, grab function address, dissassemble exe in ida pro, find that function, see what it does, look around for similar functions, eventually you will see the unit struct and how the game accesses it, could be linked list, dictionary, key value pair, continious array or others. Basicly best way is ollydbg/cheatengine combined with ida pro. GL.

Thanks very much for the info. I'm currently using a method that deals with finding the base of the player structure, then searching for that address in memory. One of the addresses listed will be a pointer spawning from the object manager (way different address from the others in the result list). At that point you just find the base of the object manager (usually the player pointer, but not always), and you have the full list of objects on the screen (pointers to their structures). For some odd reason I'm unable to make a pointer to the base of the object manager in this game, though it may be possible in others. I will investigate your method and see if it turns up better results. Thanks for taking the time to respond.
