 |
|
The following code keeps giving me this error: Failure determining what power means. I have marked the line of code which causes the problem, however, I do not know how to fix it. 
| Code: |
number = 0
power = 0
t =
{
{
'1',
[[
alloc(newmem,4096)
label(returnhere)
label(originalcode)
label(exit)
label(addStats1)
label(addStats2)
label(checkPower)
newmem:
cmp byte ptr [ebx+19],$number
jne addStats1
jmp checkPower
checkPower:
cmp byte ptr [ebx+1A],$power
jne addStats2
jmp exit
addStats1:
movzx eax,byte ptr [number]
mov byte ptr [ebx+19],al
jmp exit
addStats2:
movzx eax,byte ptr [power]
mov byte ptr [ebx+1A],al
jmp exit
originalcode:
movzx eax,byte ptr [ebx+19]
cmp eax,ecx
exit:
jmp returnhere
"game.exe"+5AA3A:
jmp newmem
nop
returnhere:
]],
[[
dealloc(newmem)
"game.exe"+5AA3A:
movzx eax,byte ptr [ebx+19]
cmp eax,ecx
]]
}
}
checkText = {0}
function CEButton3Click(sender)
if checkText[1] == 0 then
checkText[1] = 1
number = 80
power = 50
writeBytes("number",number)
writeBytes("power",power) <----This line is causing the problem
autoAssemble(t[1][2])
showMessage("Test message")
else
checkText[1] = 0
autoAssemble(t[1][3])
end
end
|
Thanks a lot.

most likely because "power" is not registered inside the target process. You may have to allocate and register that first
(also, disable sections can't be done with the autoAssemble function)

The $number and number has different meaning
| Code: |
cmp byte ptr [ebx+19],$number // A
...
addStats1:
movzx eax,byte ptr [number] // B
|
$number in (A) is to refer a lua variable 'number' ONLY during executing the AA script, it will replace TEXTUALLY $number with the hexadecimal value of lua variable 'number'. Then after the AA script executed successfully, the AA script is convert to native code in the target process. There is no more connection between the lua variable and the generated native code.
'number' in (B) should be an address symbol, that's why Zanzer in your other post make some change to your script to establish the address symbol. Probably naming the symbol as 'pNumber' would make it clear the symbol is not related to a lua variable 'number'.
But by the address symbol, you can manipulate the content value of that address via lua way
| Code: | | writeInteger('pNumber',number) |
or AA script way
| Code: | [ENABLE]
pNumber:
dd 1
[DISABLE]
pNumber:
dd 0

I have tried what you said, but it still does not work. So frustrated..
Do I need to alloc and register pNumber? Shoud it be "db" or "dd"?
