 Posted: Fri Aug 02, 2019 9:48 pm Post subject: Aobscan and writeBytes |
 |
|
So, I wanted to create a script that writes to addresses near an AOBScan signature. Here's my AOBScan Code:
| Code: |
[ENABLE]
aobscan(EnemyData, 80 00 03 40 00 00 00 01 80 4A BD DC 80 83 36 08 80 4A 86 98 00 00 00 01 80 4A BD DC 80 83 36 18 80 00 C6 28 00 00 00 00 00 00 00 02 80 83 36 38 80 1F C5 4C 00 00 00 00 00 00 00 00 00 00 00 00 80 4A 86 CC)
label(_EnemyData)
registersymbol(_EnemyData)
EnemyData:
_EnemyData:
[DISABLE]
unregistersymbol(_EnemyData)
|
Let's say I want to write the address that is 0x6C bytes away from this signature. How would I go about doing that? I tried through all of these ways, but they don't work for me:
| Code: |
writeBytes(_EnemyData+6C,01,01)
writeBytes("_EnemyData+6C",01,01)
writeBytes(EnemyData+6C,01,01)
writeBytes("EnemyData+6C",01,01)
|
The EnemyData address would need to be stored as a global variable, as this will be subsequently accessed by several different functions.

writeBytes("_EnemyData+6C",01,01)
should work, assuming that the script as actually been activated to add _EnemyData to the symbol table, and you wanted to write two 1 bytes (note that lua sees numbers as decimal unless you use 0x but for 1-9 it's the same anyway).
There's really no need for the extra label btw, you can directly register the one aobscan creates eg. | Code: | [ENABLE]
aobscan(_EnemyData, 80 00 03 40 00 00 00 01 80 4A BD DC 80 83 36 08 80 4A 86 98 00 00 00 01 80 4A BD DC 80 83 36 18 80 00 C6 28 00 00 00 00 00 00 00 02 80 83 36 38 80 1F C5 4C 00 00 00 00 00 00 00 00 00 00 00 00 80 4A 86 CC)
[DISABLE]
unregistersymbol(_EnemyData) |
just to test the lua code you could do something like this | Code: |
-- fake the AA script registering the symbol
unregisterSymbol('_EnemyData') -- can't register when already registered
registerSymbol('_EnemyData', 0x400000) -- whatever the real address is for testing
-- test whatever with the symbol registered
local address = getAddress('_EnemyData+6C')
return ('%X'):format(address) -- just printing the address in hex
|
Then you know if it's the lua code or the AA code.
