Hi all,
I want to write a bot for LOTRO which can collect resources. The first step for me is to get the position data. As I would like to make it "perfect" I decided to try to get the informations right from the memory and not writing to some logfiles.
My problem now is not to find the memory adresses with CE.. It is more that the addresses keeps changing.
I read here in the forum and found some talking about pointers.
I think this is what is happening here. (If I am wrong please correct me)

The next problem is that I not only get one hit I allways get about 24. This amount also keeps changing.

I found a post here in the forum which said I should take one of the addresses and use "Find out what accesses this address".

I logged in several times and find in one address values which are the same.
My problem is that I do not understand what they exatly mean.. Or if they are really the pointer I am looking for.
Can someone help me out with this please?
I just want to get the position data from memory.. thats all.
Please have a look at the attached screenshot. The value which is allway the same is the last one (004669..)
Thanks
Daniel Crying or Very sad

There is a tutorial included with Cheat Engine (check its directory).
The last parts of the tutorial are about Pointers and how to find them.

I suggest you try those first. If they're too hard, or you don't get something, visit the Cheat Engine Tutorial section, you'll find many tutorials on how to use CE there.

If the problem persists, ask again in here :3

I actually think I found the pointer but it keeps showing the wrong value. perhaps i get something wrong from the tutorial..
The exta info shows lea esi, [ esp+64]
So I took the esp in hex + 64 hex and used the value as offset.. But it did not work.
Any suggestions?
Thanks
Daniel

You're best to first try out the ones with "MOV" as command. For they copy the address from one spot to another (what a pointer does, sort of)

So in this case, you'd have to get more information on one of those 3 addresses. (more likely the last MOV in your picture)

The lea instructions are invalid. In this case the address accessing it is actually rep movsd (edi is the address)
rep movsd is useless for finding pointers, so go with the mov edx,[ecx+14] or fld dword ptr [ecx+4]

Ah I found the error. Stupid me. I just forgot to set the pointer tyape to float.
Thanks to all for your support.
You can close this one.
Cheers
Daniel
