[Help] Java Bot reading offset values..^^°

[kmJeepers]

Hello everyone!
I'm new to the scene and i come with a problem:
My first try of writing a HP showing tool, it only returns "0"...


First of all I decided to write a small Bot in Java(I know most peolpe suggest doing it in c#, but i want to try something different^^°)

Well, first i Got my special method where i try to grab the players HP:

public void run() throws NativeException, IllegalAccessException
	{
		int playeradress = 0x010BD5F4;
		int puffer,buffer,playerbase;
		
		puffer=Get.getData(playeradress);
		puffer=puffer+0x34;
		puffer=Get.getData(puffer);
		puffer = puffer+0x24;
		playerbase=Get.getData(puffer);
			
		int base=playerbase+0x8;
		base=Get.getData(base);
		base=base+0x260*4;
		buffer=Get.getData(base);

		output.setText(Integer.toString(buffer));
		
	}

Then I Got my special Offset grab method in the class Get:

public static  int getData(int hex) throws NativeException, IllegalAccessException
	{
		WindowsUtils.setSeDebugPrivilege();
		int pid = 4128; 
        HANDLE processHandle = Kernel32.OpenProcess(Kernel32.PROCESS_QUERY_INFORMATION | Kernel32.PROCESS_ALL_ACCESS, false, pid); // pid: process id 
        JNative readProcessMemory = new JNative("Kernel32.dll", "ReadProcessMemory"); 

        if (processHandle.equals(null)) 
           System.out.println("NULL"); 
         
        int b = 128; // buffer size 
        Pointer p = new Pointer(MemoryBlockFactory.createMemoryBlock(b)); 
 
        int base=hex;
        readProcessMemory.setRetVal(Type.INT); 
        readProcessMemory.setParameter(0,processHandle.getValue().intValue()); 
        readProcessMemory.setParameter(1,base); 
        readProcessMemory.setParameter(2,p); 
        readProcessMemory.setParameter(3, b); 
        readProcessMemory.invoke(); 
        int val = readProcessMemory.getRetValAsInt(); 
        Kernel32.CloseHandle(processHandle);
        
        return p.getAsInt(val);
       	}

Well the grab methodic works, so i could grab the players name in 3.0 with this structure...
Even if this is in Java i thinks its kind of similar to c#, so i think you will be able to give me advise how to make this work...

I would appreciate Help and Tipps from you^^°

This makes AutoIt look good.

base=base+0x260*4;
The correct offset for health is UNIT_FIELD_HEALTH = 0x17, I have no idea where you grabbed 0x260 from.

[kmJeepers]

ookay i corrected that, but that does'n change the return value... i checked, and even the value for "playerbase" is "0"...

[Robske]

That hardcoded process id cannot be right...

Also, your ReadProcessMemory call doesn't seem correct either...
ReadProcessMemory Function (Windows)

Well a i said that code worked for a static entry in 3.0....
I took that code from: java memory reader any trick to getting access to WOW memory
- So that method "ReadProcessMemory Function" is an internal method by "Jnative" an extenrnal app to read dlls....

It can't and won't work if WoW's process ID isn't 4128

well i enter the correct pid every time i run a new instance of wow XD

Thanks for the good laugh mate. :P

Jesus. That's a pain in the ass, don't you think? FindWindow+GetProcessId much?

[kmJeepers]

I think i'm capable of programming something like that... but it isn't that easy in java ^^°
Well but doesn't change the fact that the main function doesn't work...
i would like to know whether my main function has issues in the code methodic of reading the memory entries...

[kmJeepers]

in short:
1.getting the pid in java isn't the problem
2. Is my code right till now?

--> if it's right i think i have to use something else than "Jnative"(used in the code above)
