Hi !
I am creating a tool for GTA:SA game, that gets values from addresses like money ( http://www.gtamodding.com/index.php?...esses_%28SA%29 ) and then saves them, and later i will want it to be like game stats, that i will be able to show.
The problem is, that i want to get the value from health address, that is dynamic.However, its very easy to get that address using Cheat Engine, (just add new address manually, and then use pointer + health addres to get valid address.
The pointer is 0xB6F5F0 and its always the same,
Health address that i have to add to the pointer is CPed +0x540, so i have to add pointer value and 0x540 value to get valid address, that i can read its value.
I found this class, that has functions like "readDynamicInt" etc, or "getAddress"
I just want to use readDynamicFloat (health address is float type, but i may be wrong, and i need to use other function)
So i tried using it like this:
Label1.Text = readDyamicFloat("gta_sa.exe", &HB6F5F0, "540")
but when i try to use it, it shows a msgbox with "Failed to open gta_sa" and i have tried to use this class before, and it also was giving that error.However i have tried other class, to try to write something to a address, and it worked for me.But i want to read a dynamic address, and its the only class i found with those functions.I checked the code, and it detects the process, but it cant open it, could someone help me/fix this ?
Im using Windows XP SP3 and Visual Basic 2008 Express
