java - JNA - Getting Base address

Question

Recently I have been working on a little project of mine, which is Memory reading/writing in java for native games (C/C++/etc).

At the moment I have a base where I can read and write to memory of games, but I now need a way to get the Base address of the running application. For example:

I have a list of pointers that I have collected using Cheat Engine and its Pointer searcher. These are stable and work each time the game reloads.

The problem I am facing now, is the first pointer uses the base address of the program (which changes every time the program restarts): "ac_client.exe"+000DF73C

I am in need of a way to get the base value of "ac_client.exe" using JNA.

I have done a lot of research and found a few ways to do it in C++, but my knowledge of C/C++ is pretty limited.. I am finding it difficult to convert it to Java using JNA and I thought I would ask here and see if anyone would be able to be of assistance or know of alternate ways of doing such a feat.

Thanks for any help in advance, Kaden.

Answer 1

I got it working after a bit of messing around with what Alex posted, and managed to get it working.

for anyone else who wanted to get something like this working, have a look at that project that Alex posted and you will see the required classes you will need. then I just used this:

public int getBaseAddress() {
        try {
                Pointer hProcess = gethProcess();
                List<Module> hModules = PsapiHandler.getInstance().EnumProcessModules(hProcess);

                for(Module m: hModules){
                        if(m.getFileName().contains(exeName)){
                                misc.log(m.getFileName() + ": 0x" + Long.toHexString(Pointer.nativeValue(m.getEntryPoint())));
                                return Integer.valueOf("" + Pointer.nativeValue(m.getLpBaseOfDll()));
                        }
                }
        } catch (Exception e) {  e.printStackTrace(); }
        return -1;
}
