Add a value into the script

[3qalves3]

Hello im trying to learn some basics and i need some help here.



Rbx is the number that i know already, i want to know how i can find the xmm0 value and its possible to change the xmm0 value ?

Sometimes you can simply change the line to something like this
newmem:
mov [rbx],(double)100 // or if its float you can write (float) if its an integer you can simply do # without the parenthesis

everything else can remain the same. most of the time it works but some games have checks later in the assembly which can make weird results or crashes. just depends on what you are trying to do.

Nerdy: Aaactually....

Code: Select all

mov [rbx],(double)100

will result in invalid code as the value in `mov [memoryaddress],value` can only be 32-bits

you'd want to do:

Code: Select all

mov [rbx],(double32l)100
mov [rbx+4],(double32h)100

or

Code: Select all

mov rax,(double)100
mov [rbx],rax

Code: Select all

mov [rbx],(double)100

will result in invalid code as the value in `mov [memoryaddress],value` can only be 32-bits

You would think whichever moron made the AMD64 op codes for a 64-bit environment would allow for the transfer of 64-bit data, but I guess that makes too much fucking sense.

You do all realize it's not LUA, right?
It's either the wrong forum or the answer is expected in LUA.
