In "James Cameron's Avatar-The Game", while trying to make the number of missiles of RDA choppers infinite, I used the following auto assembler script.
--------------------------------
[ENABLE]
alloc(newmem,2048)
label(returnhere)
label(exit)

newmem:
push edi
mov edi,0
mov [eax],edi
pop edi

mov [esi+000002E0],eax
//originalcode:
//mov [esi+000002E0],eax

exit:
jmp returnhere

"Dunia.dll"+6921A6:
jmp newmem
nop
returnhere:


[DISABLE]
dealloc(newmem)
"Dunia.dll"+6921A6:
mov [esi+000002E0],eax
//Alt: db 89 86 E0 02 00 00
--------------------------------
However on enabling the script, the game freezes after firing 1 missile. Is there anything wrong in this script??

If [esi+000002E0] holds the value, mov [esi+000002E0],64 {100 as example}.

In your script you're moving a value into the address eax holds.

I suck at explaining things, so I hope that put the point across.

Maybe better to xor eax or mov eax,0 since the code could be using eax later, for example to set the display. Whatever the case, the issue is that you're currently writing a zero into the address that eax holds (which is likely small enough to be in kernel memory) instead of into eax itself - remove the brackets around the eax and you're golden.

Hey thanks justa_dude, it works!!
