Code:
mov [edi+000001bc],eax


mov = moves eax into [edi+000001bc]
[edi+000001bc] = and address
eax = a value

Code:
[edi+000001bc]

edi = address
1bc = offset

address + offset = pointer

What writes to this address is what it sounds like, what writes to the memory address. What accesses is what reads or writes to the memory address.

Depends on the situation, most times i use write. but there are times you need access's. I have friends who use nothing but access's.

hmm ok one more question guys, if I were to change the eax/edi/ecx or an address, would I have to zf a address that jumps near by in order for the modifying of the address to take affect?


Cause i was following x0r's guide on how to get god-mode and it said i should look for the address that attack is in, and I found 3 address that displayed the damage I took whenever I received physical damage, but when I see what writes to them, I get a bunch of other address with
mov ~~~~~~, edi/eax/ecx and i tick whatever it says for the op-code and replace it with 0, some of the address will give me client sided 0 damage for crits but will still die when they are hitting me for 0? I dunno im confused again Mad

Edit: I also modified one address at a time...would it matter if I did one or two at a time or no?

Edit2: srry to ask this guys but what is js and jns mean for the opcodes?

Edit3: lol don't wanna make new post so ill jsut edit again Smile. Uhm about the call function (couldn't get much info from the guide) It tells me to call whatever address it says and jump back to whatever I was doing correct, but if it was calling an op-code that jumps would i have to follow the whole code until the int3? or just the first line and go back to where it first called?


Thanks guys, all this help has been really helpful in helping me learn how to hack Smile

If there is a jcc instruction there in the code, it is possible to have that yes.
