 Posted: Wed Feb 15, 2012 3:14 pm Post subject: Auto assembler pointer condition |
 |
|
I have one code that write to many addresses it's location is:
[edi+48]
if i auto assembly:
mov [edi+48],5
hundreds of addresses will be set to 10
now i know that i have to find the pointer of the address i want to change the code ... and i did so.
pointer =
"game.exe"+ABC offset1=245 ;2=ff ;3=0 ;4=4 ;5=ab
and that i have to write a code that compares the address given by the pointer with the address that [edi+48] writes on, and if equal jump to my code if not continue with originalcode
but i don't know exactly how to do that:
i tried:
| Quote: | [ENABLE]
alloc(code,10)
label(codereturn)
label(codeforme)
code:
pushfd //save flags
push eax //save the eax register
mov eax,"game.exe"+ABC //move base adress into eax
mov eax,[eax] //move the value from eax into eax
add eax,245 //add first offset into eax
mov eax,[eax] //again move the value from eax into eax
add eax,ff //add second offset into eax
mov eax,[eax] //and so on
add eax,0 //third offset and so on
mov eax,[eax]
add eax,4
mov eax,[eax]
add eax,ab //add last offset; eax now holds player's address
cmp eax,[edi+48]//compare player adress with all addresses
je codeforme //if equal jump to code codeforme and do not execute originalcode
popfd //restore flags
pop eax //restore eax
mov [edi+48],eax //else execute originalcode
jmp codereturn //continue executing from original address
codeforme: //actual code that works only with the player
popfd //restore flags
pop eax //restore eax
mov [edi+48],0 //i want my value of address to be 0
jmp codereturn //continue executing from original address
"game.exe"+1280C5: //this code here writes to all addresses
jmp code
nop
codereturn:
[DISABLE]
dealloc(code)
"game.exe"+1280C5:
mov [edi+48],eax |
I really have no clue... where is it wrong ?

cmp eax,[edi+48]
You are comparing the address of your player to the value
Try:
| Code: |
push ebx
lea ebx,[edi+48]
cmp eax,ebx
pop ebx
je codeforme
