Currently I have a aobscan script that nops a health function. my problem is this takes around 30 seconds or longer to enable. would like to put a specific region in this scrip to hopefully cut down the time.


<AssemblerScript>[ENABLE]
aobscan(inj_health,0F 38 F1 44 19 2C 75 09 48 83 C4 28 E9 F3 0C 00 00)

label(health)
registersymbol(health)

inj_health:
health:
db 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90

[DISABLE]

health:
db 0F 38 F1 44 19 2C 75 09 48 83 C4 28 E9 F3 0C 00 00

Firstly, this isn't Lua, it's auto assembler.

Secondly, use code tags when submitting code please [ code ] ... [ /code ] (without spaces).

Lastly, you should use aobscanregion

If you know it's in a specific module, use the aobscanmodule AA function.

Otherwise, more advanced logic can be done in Lua. e.g. only scan through executable read-only regions instead of everything. See celua.txt for documentation.
Lua code can be run when the script is enabled/disabled with {$lua} blocks like so:
Code:
[ENABLE]
{$lua}
if syntaxcheck then return 'define(foo,0)' end

local result = assert(AOBScan('0F 38 F1 44...', '+X-C-W'))
local addr = getAddress(result[0])
result.destroy()
return ('define(foo,%08X)'):format(addr)
{$asm}
registersymbol(foo)
...

Look into mgr.inz.Player's aobscan Nth result extension here.
That starts searching where you tell it to.
