 |
|
Have done an easy script, but when I use 'label' for my address, it would say "INJECT Error:Not all results found" and then game would crash if I triggered relevant action.
| Code: | aobscanmodule(INJECT,HWR.exe,5C 00 90 0F B7 C5 90 F3 0F 11 44 24 1C 8B 4C 24 1C 81 F1) // should be unique
alloc(newmem,$1000)
alloc(mag,4)
label(code)
label(return)
label(mag)
mag:
dd (float)1
newmem:
movss xmm0,[mag]
jmp code
code:
movss [esp+1C],xmm0
jmp return
INJECT+06:
jmp newmem
nop
return:
registersymbol(INJECT)
[DISABLE]
INJECT+06:
db F3 0F 11 44 24 1C
unregistersymbol(INJECT)
dealloc(newmem)
|
Then I changed to use 'registersymbol', it worked well. Why is that?
PS: I didn't use 'mag' outside the script. The only thing I triggered was this script.
| Code: | aobscanmodule(INJECT,HWR.exe,5C 00 90 0F B7 C5 90 F3 0F 11 44 24 1C 8B 4C 24 1C 81 F1) // should be unique
alloc(newmem,$1000)
alloc(mag,4)
label(code)
label(return)
mag:
dd (float)1
newmem:
movss xmm0,[mag]
jmp code
code:
movss [esp+1C],xmm0
jmp return
INJECT+06:
jmp newmem
nop
return:
registersymbol(INJECT mag)
[DISABLE]
INJECT+06:
db F3 0F 11 44 24 1C
unregistersymbol(INJECT mag)
dealloc(newmem)

when you use alloc you must not use label on the same symbol
because you used label(mag) the alloc got erased. and since there's no address specifier before mag: mag will be put at address 00000000, which is not valid. so when the game accesses mag (address 00000000) it'll crash

I see. I did found the address 00000000 but not paid much attentino to it. Thank you very much for your prompt reply.
