Hi!

I found the address in the game: Monster Boy, is responsible for the walk speed of the character, so when i make an AOB Injection i have the original code:

movss [rbx+38],xmm0
jmp return

I'm new in assembler and in these codes, but reading the forum, i replace the original code, by:

Code:
...
label(myv)

newmem:

code:
  movss xmm0,[myv]
  movss [rbx+38],xmm0
  jmp return

myv:
  dq (float)1.2

...


The default value of the float point is 0.7, but i set to 1.2 that is fine for me. All works fine, but i have a problem:
This code works if i walk forward, but when i go back (the float value gets negative) it's doesn't, because i need to set in code the negative value instead of positive to work, i. e. dq (float)-1.2

Please, how to make the code to know if is a positive number, then the code to set 1.2, if is negative than to set -1.2?

just change it to mulss the original with whatever 1.2/0.7 is um... 1.714... according to my calculator. Then if it's positive it stays positive and becomes 0.7*1.714 = 1.2 and if it's negative then it's -0.7*1.714 = -1.2
