Hey y’all,
I’m trying to create a script in NFS Most Wanted 2012 (NFS13.exe) that changes the color of police cars. The game uses one dynamic address for each police unit, therefore requiring a pointer to work.
And this is the pointer of the first police unit:
Offset 1: 1DB0
Offset 2: A1314
Base Address: 10EC5F0

And this my code:

Code:

[ENABLE]
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
label(changeColor)

newmem:
changeColor:
mov eax, [10EC5F0]
mov eax, [eax + 1DB0]
mov eax, [eax + A1314]

mov [eax+30], (float)1.0 // Red
mov [eax+34], (float)1.0 // Green
mov [eax+38], (float)1.0 // Blue

// Metallic finish
mov [eax+60], (float)0.005
mov [eax+64], (float)0.005
mov [eax+68], (float)0.005

// Gloss and Matte Finish
mov [eax+7C], (float)0.25 // Gloss
mov [eax+80], (float)0.02 // Gloss
mov [eax+9C], (float)0.5 // Matte finish (optional)

originalcode:
movsd xmm0, [eax+30] // Load the original color value to pass through
jmp exit

exit:
jmp returnhere

// Crown Vic direct memory address
10EC5F0:
jmp newmem
returnhere:

[DISABLE]
dealloc(newmem)
10EC5F0:
movsd xmm0, [eax+30] // Restore original color

The error says that this line cannot be compiled

Code:

mov eax, [eax + 1DB0]

-This pointer ALWAYS works.
- I tried combining the base address and both offsets into one line.
-Whether or not if I add “NFS13.exe”+, it still doesn’t work.

Any help would be appreciated.

Don't put spaces around `+`

You should be using `game.exe+...` for the base address. Just because it doesn't seem to change for you doesn't mean it can't.
