Hey,
I've been trying to make a small cheat table for a game called Nuclear Throne, apparently in the game there are multiple different types of damage and i managed to pinpoint all of them and made "infinite hp" scripts for all, only problem is, one of them gives infinite hp to enemies as well. I did the usual struct dissection and found a 4-bit value consistently same among players and different on enemies (players all 5, enemies all 0)
my problem is the syntax of the code to use to distinguish the player from the enemy and give infinite hp to player only. i did experiment for a long time, hopefully someone experienced can help me properly use cmp function
This is the original code :
*******************************
label(code)
label(return)
newmem:
code:
movsd [ebx],xmm1
jmp nuclearthrone.exe+1C2CD4
jmp return
HP4:
jmp newmem
nop
return:
registersymbol(HP4)
******************************
[ebx] is address of HP, i found address of differentiating type is [ebx+1C], where 5 is player and 0 is enemy. can someone help me code the syntax.
also, what i normally do is:
********************************
label(code)
label(return)
newmem:
code:
nop
nop
nop
nop
jmp nuclearthrone.exe+1C2CD4
jmp return
HP4:
jmp newmem
nop
return:
registersymbol(HP4)
**********************************
this nullifies the code but gives enemy infinite hp

you meant 4-byte value? if so then:
Code: | label(code)
label(return)
newmem:
cmp byte ptr [ebx+1C],05
jz nuclearthrone.exe+1C2CD4
code:
movsd [ebx],xmm1
jmp nuclearthrone.exe+1C2CD4
jmp return
HP4:
jmp newmem
nop
return:
registersymbol(HP4) |

jz is a conditional jump and jmp is not
