Trying to make a simple no clip hack for vampire masquerade the bloodlines, i know that you can just write noclip in the console to get no clip but i do this for learning.

Here is my script:

Code:
[ENABLE]

aobscanmodule(clipbase,vampire.dll,8B 81 5C 03 00 00 8B) // should be unique
alloc(newmem,$100)

label(code)
label(hack)
label(original)
label(return)

globalalloc(_noclip,4)

newmem:

code:
cmp dword [ecx+00000024],79616C70 //79616C70  //463E0400
je hack
jmp original
  jmp return

hack:
mov [_noclip],ecx
mov eax,[ecx+0000035C]
jmp return

original:
mov eax,[ecx+0000035C]
jmp return

clipbase:
  jmp code
  nop
return:
registersymbol(clipbase)

[DISABLE]

clipbase:
  db 8B 81 5C 03 00 00

unregistersymbol(clipbase)
dealloc(newmem)


And it works fine. But the problem is that is compares "play" instead of player:

String i want to compare with:

So how can i compare like 7 bytes etc?
cmp byte = 1 byte
cmp word = 2 bytes
cmp dword = 4 bytes
cmp qword = 8 bytes.

How can i compare 7 bytes? Thanks!!

Code:
cmp dword ptr [ecx+00000024],'play'
jne original
cmp word ptr [ecx+00000028],'er'
jne original
cmp byte ptr [ecx+0000002A],0
jne original
