having issues setting a float

Post by jelly time » Thu Mar 14, 2019 7:35 pm

trying to make a script which would set the timer for item restocks so it would be instant, but when I enable the script and buy something the game immediately crashes. This is my first time making a script from scratch but I have a feeling it has to do with the value being a float and me setting it as something wrong.

Code: Select all

{ Game   : Little Inferno.exe
  Version: 
  Date   : 2019-03-14
  Author : Jelly Time
}

define(address,"Little Inferno.exe"+E326)
define(bytes,D9 1C 01 5B 83 C4 1C)

[ENABLE]

assert(address,bytes)
alloc(newmem,$1000)

label(code)
label(return)

newmem:
mov [ecx+eax],#1
code:
  //fstp dword ptr [ecx+eax]
  //pop ebx
  //add esp,1C
  jmp return

address:
  jmp newmem
  nop
  nop
return:

[DISABLE]

address:
  db bytes
  // fstp dword ptr [ecx+eax]
  // pop ebx
  // add esp,1C

dealloc(newmem)

{
// ORIGINAL CODE - INJECTION POINT: "Little Inferno.exe"+E326

"Little Inferno.exe"+E307: 8B CA                 -  mov ecx,edx
"Little Inferno.exe"+E309: C1 E2 04              -  shl edx,04
"Little Inferno.exe"+E30C: 89 B4 02 64 01 00 00  -  mov [edx+eax+00000164],esi
"Little Inferno.exe"+E313: FF 80 60 01 00 00     -  inc [eax+00000160]
"Little Inferno.exe"+E319: D9 44 24 10           -  fld dword ptr [esp+10]
"Little Inferno.exe"+E31D: 5F                    -  pop edi
"Little Inferno.exe"+E31E: 5E                    -  pop esi
"Little Inferno.exe"+E31F: 83 C1 17              -  add ecx,17
"Little Inferno.exe"+E322: C1 E1 04              -  shl ecx,04

"Little Inferno.exe"+E32F: CC                    -  int 3 
"Little Inferno.exe"+E330: A1 AC 9E E6 00        -  mov eax,["Little Inferno.exe"+349EAC]

"Little Inferno.exe"+E345: A3 0C 9F E6 00        -  mov ["Little Inferno.exe"+349F0C],eax
"Little Inferno.exe"+E34A: A1 B8 9E E6 00        -  mov eax,["Little Inferno.exe"+349EB8]

Don't comment the entire code, as you're messing it up by not popping the ebx, etc. And If you're setting a float, you can do: mov [ecx+eax],(float)1
