Getting wrong Value [ Player Health ]

[Eviin]

Hey guys,

I want to Read the Current Playerhealth of my Character but Im getting a wrong value.
Used Programming-language: Delphi
Current WoW Version: 4.3.4 (15595)

Can anyone help please ? ^^

Constants:

unit_field_health = $12;

Read health:

function GetPlayerHealth() : Integer;
var
  Storage : DWORD;
  Puffer  : Integer;
  Bytes   : NativeUInt;
  dSize    : DWORD;
begin
  ReadProcessMemory( HandleWindow, ptr(PlayerBase + $8), @Storage, sizeOf(dSize), Bytes );
  ReadProcessMemory( HandleWindow, ptr(Storage + (UNIT_FIELD_HEALTH + $8) * 4 ), @Puffer, sizeOf(dSize), Bytes );
  result := Puffer;
end;

Descriptor is at 0xC

Thank i will try it but i have another problem... ^^

Sometimes the Module and player Base Address cannot be loaded.
The functions returns already 0.

Hmm... i'll try to make a delphi instruction on short terms. More people asking me about how to do stuff in Delphi.

So I guess you have access to all objects, looped through them, and found the player offset? I used the precise memory offsets to make things clear and did not use constants.
You first read the descriptor-value then you simply read the health;

  lDescriptor := ReadInt32(gPID, lPlayerObject + $c);     
  lObjectHealth := ReadInt32(gPID, lDescriptior+ (($12 + $8)*4));

So I decided to make a VERY QUICK example in Delphi.
Download link: http://dl.dropbox.com/u/86348557/example.zip
It only contains Delphi project files, and no compiled executables. So no viruses, just text.

When running it in delphi and pressing the button on the form, make sure the WoW process is already running.

The package contains:
- ExampleWoW.dpr --> Delphi project file
- UInt64Lib.pas --> Used to read UINT64 from memory
- UnitMain.pas --> My main unit. Contains a simple memo field, upon pressing the button you will get the values of the running WoW process. Also contains a few standard functions; GetModuleBaseAddress, GetProcessID, ReadShort, ReadString, ReadInt32, etc.
- UnitMain.dfm --> Contains the form and its objects.

Like said in first line; made this VERY QUICK & DIRTY. So all memory offsets are also written in the code.

Have fun with it!
