Posted: Thu Jun 16, 2011 12:07 pm Post subject: finding a string array |
|
|
hi,
I'm trying to locate an array of string pointers for this game I'm trying to write a bot for. The array should keep the pointers to the chat's strings. I can easily find the addresses of the strings, but I cant seem to find the array that keeps all different string pointers.
From what I know from the game, I suspect there should be a string array of length 255 or 256 that is used to keep chat data.
Anyone could help me out on how to find it please?
regards,
Klmdb

You probably need to find the top of that structure and iterate over the strings (find the first message and begin reading)

I can find the memory region where the first string is stored, but it's just a random place in the memory, so it changes every time I start the game.
Also, I've noticed that when other programs allocate strings, they also write to this memory region.
Hence I suspect the strings are allocated somewhere in the memory there just happens to be room for them, but the game keeps an array of pointers to each of the strings. It's that array I'm trying to find.
Am I making sense?

This is normal; you need to find pointers. Memory addresses do not remain constant. If you did Step 8 of the CE tutorial, you know what I mean.
If you're attaching CE to the game's process, then you are searching the game's memory and it is not shared with something else, at least I don't know how that would be possible.

I know what you mean but I can't seem to find the pointer. This is what I tried (I think it's similar to what the tutorial says):
1) search for a chat string
--> this usually results in 3 memory regions, one of which is a region that holds many other chat strings
2) select 2 memory addresses: the first a couple of bytes left of the string's first char, the second a few bytes right of the string's first char
3) search the memory for a 4 byte value between the first and the second value ( = search for the pointer to the string)
This gives 0 results --> the pointer cannot be found
I tried this method for all resulting addresses from step 1 for a bunch of chat lines, but never found a single pointer.
Any hints?

I would recommend doing the tutorial all the way through a couple times to make sure you're very familiar with CE, it sounds like you have a couple of knowledge gaps you could fill.

Some more specific pointers would be appreciated. I'm sure that if I read every tutorial and every guide I may find a solution but that kind of answer isn't of much help.
thanks

Well if you knew what I was talking about, you'd know it was not something you read, but something you DO.
The tutorial is a walkthrough of how to use CE's features, it opens automatically the first time you start.

This wreaks of you needing multilevel pointers, Step 8 of the CheatEngine tutorial.

Well if you don't even bother to look, you'll never find anything.
