Posted: Sat Oct 08, 2016 4:26 am Post subject: Problem with AOB injection, address keep changing

This script is working but it will crashed everytime i restart game client because an address of "mov eax,04C18E80" keep changing.

Code:

[ENABLE]

aobscan(Health,89 08 E8 ?? ?? ?? ?? 8B 40 2C) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
mov eax,04C18E80 <--- this address 041F8E80 is keep changing everytime restart game client.
mov [eax],(int)10
jmp return

Health-5:
jmp newmem
nop
return:
registersymbol(Health)

[DISABLE]

Health-5:
db B8 80 8E ?? ?? 89 08 <--- this part also gives me a problem, if i turn it off it will crash game client. so i have to keep it on.

unregistersymbol(Health)
dealloc(newmem)

{

}

Sorry, didn't see you were already using them. Wildcards are the ?? symbols that can be used for code that changes.

I think your problem may be that your AOB scan is simply too short, try including more bytes in the scan.

The AOB is fine, everytime i restart the game it always gives the correct address (1 result in search) and leads me to mov [eax],ecx.

Code:

mov eax,04C18E80 <---- this address keep changing
mov [eax],ecx <---- this address i use to change health
call 179C6118 <---- this address keep changing too

the problem i stuck between those two.

instead of

Code:

mov eax,04C18E80

try

Code:

reassemble(Health-5)

or change your hook position and just replace

Code:

""+179F8B01: 8B 0D 80 8E C1 04 - mov ecx,[04C18E80]
""+179F8B07: 49 - dec ecx

with

Code:

mov ecx,(int)10
nop
nop
