 Posted: Thu Mar 17, 2016 12:09 pm Post subject: How to call the exact aob and save intu a local variable |
 |
|
hi guys
im strugling a little...
im trying to figure out how to take an aob that uses wilds example
62 ?? 66 ?? ?? 73 63 ?? 62 ?? 66 ?? ?? 66 ?? 73
which if i scan it say this week it gives an exact value of
62 07 66 8A 0C 73 63 09 62 08 66 FE 02 66 44 73
but nxt week it might b different on the parts where there is wilds used...
so to come to the point...i want to do an aob scan for 62 ?? 66 ?? ?? 73 63 ?? 62 ?? 66 ?? ?? 66 ?? 73 on the current game version...get 62 07 66 8A 0C 73 63 09 62 08 66 FE 02 66 44 73 as a result, and put the result into a local...say local myobstr=aobcanresult
the reason being, i need some aob parts from specific functions to rebuild an replace aob for another scan...i want it to auto update...thus i make use of wilds, as deobfuscation make them change regularly...

| You can try readmem.

hmm..the readmem function looks a little difficult...i dont understand it yet...
will it b something like
aobscan(myaobcanresult,62 ?? 66 ?? ?? 73 63 ?? 62 ?? 66 ?? ?? 66 ?? 73)
local myobstr=readmem(myaobcanresult,16)
the readmem parts i saw got me a bit lost...as it looked different from the other lua script ivew been trying to learn...

I'm not entirely sure what it is, exactly, that you are trying to accomplish (or avoid). Can you explain it, please?
Regarding readmem, if you can explain your issue and paste your script here, perhaps members can just show you what you need to do. Anything regarding LUA will have to be answered by others, as I am not proficient with that.

readmem is an AA command, not lua function, the desc in ce help file:
| Code: | | READMEM(address,size) :Will write the addresses at address at the location this instruction is placed |
The list address is the source address where bytes will be copy from, size is how many byte to copy, in DECIMAL. The target address is the implicit address where the command is.
The lua equivalent may be some thing like this:
| Code: | | writeBytes(targetAddress,readBytes(sourceAddress,size,true)) |

i will try to explain some more...
lets say aob1="24 ?? 62 05 66 ?? ?? 4f ?? ?? ?? ?? " <one function>
aob2="00 d1 2c ?? ??" <from 2nd function>
aob3="63 ?? 27 63 ?? ??" <from 3rd function>
so...what i wish to acomplish is something like
aobswap(aob1, aob2..aob3)
but, because of the wildcards, aob2 and aob43 isnt exact aob values, but when they get scanned exact vaues get filled into the "??" spaces...so,
the aob2 "00 d1 2c ?? ??" must become something like local aob2exact="00 d1 2c aa bb"
and the aob3 "63 ?? 27 63 ?? ??" must become something like local aob3exac"63 dd 27 63 ee ff",,,but i dont know how to get it from "63 ?? 27 63 ?? ??" to "63 dd 27 63 ee ff"...
because if a kust put them together like aobswap(aob1, aob2..aob3) the "??" for aob1 will be used in the replace...
hvnt made that part of the script yet...stll trying to figure out how to get the ?? issue solved
edit...
can i say aob2exact = AOBScan(aob2)
will that give me the result "00 d1 2c aa bb" ?
i always thought AOBScan() just returns a true or false depending on if it finds the aob or not...
i will put it to the test...might hv found my own anser...
 ...thnx guys

-Yes, I know. But the OP is posting in the LUA sub-forum, so I assume an LUA solution was needed. 
Ludwig-
You may need to use readmem in conjunction with aobswap. I've never had a need to use the aobswap feature, so I cannot say for certain how it would need to be done.

at the moment my script uses
luacall(AobswapC("00 84 ?? ?? ?? 80 64 ?? 0d 03 0d 66","d0 30 24 00 48"))
for most aobs...where AobswapC is a function made up already to do the swap...but...as i tried to explain above...some replace aobs is a bit more tricky...i basically need to "build" the replace ob from data in other functions...which i can scan aswell..

| Code: | [ENABLE]

aobscan(scan2,00 d1 2c ?? ??)

Nope...ive tried these above...i get errors trying to use
[ENABLE]
or the code below it...
so...i tried this by myself below
| Code: |
function AobBuild()
local scan1=''
local scan2=''
local search=''
local replace=''
local stringbuild1=''
local mystr=" "
local i=0;
local j=0;
scan1 = AOBScan("d0 30 60 ?? 01 66 ?? ?? d0 66 ?? ?? 66 ?? ?? 02 80 04 d5 d0 66 ?? ?? 46 ?? ?? ?? ?? ??")
if scan1~=nil then
j = stringlist_getCount(scan1)
for i = 1, j do
stringbuild1=stringlist_getString(scan1,i-1)
mystr= mystr..stringbuild1
end
scan2 = mystr
showMessage("scan1: "..scan2)
end
end
|
"scan1 0808B0A4"
is what i get atm
this gives me the address of scan1...instead of the value...
"scan1 D0 30 60 96 01 66 8C 0A D0 66 82 08 66 AB CB 02 80 04 D5 D0 66 A1 0A 46 58 00 D1 66 81"
is what i would like
Any idea how i can get it to put the value of that scan into scan2?
EDIT---
ok..got it sorted with this...:
| Code: | function DEC_HEX2(IN)
if IN<=0 then
return '0'
end
local B,K,OUT,I,D=16,"0123456789ABCDEF","",0
while IN>0 do
I=I+1
IN,D=math.floor(IN/B),math.mod(IN,B)+1
OUT=string.sub(K,D,D)..OUT
end
return OUT
end
function AobBuild()
local scan1=''
local mystr=" "
local Address = scan1[0];
local ReadBytes = readBytes(Address,29,true);
for _,String in pairs(ReadBytes) do
local Hex = DEC_HEX2(String);
if Hex:len()==1 then
Hex = '0' .. Hex;
end
ReadBytes[_] = Hex;
mystr= mystr..Hex.." ";
end
showMessage(mystr);
end; |
