Original injection without edits.
fld dword ptr [eax+24] is current stamina.
| Code: | aobscan(Stamina,F3 83 C4 10 39 36 8B 46 14 D9 40 24 D9 5D D0)
alloc(newmem,$100)
label(code)
label(return)
newmem:
code:
fld dword ptr [eax+24]
fstp dword ptr [ebp-30]
jmp return
Stamina+09:
jmp newmem
nop
return:
registersymbol(Stamina) |
Is it safe to edit like this?
| Code: | aobscan(Stamina,F3 83 C4 10 39 36 8B 46 14 D9 40 24 D9 5D D0)
alloc(newmem,$1000)
label(code)
label(return)
newmem:
fld dword ptr [eax+20]
fstp dword ptr [eax+24]
jmp return
code:
fstp dword ptr [ebp-30]
jmp return
Stamina+09:
jmp newmem
nop
return:
registersymbol(Stamina) |
fld dword ptr [eax+20] is max stamina.
Wondering cause of two fstp.

Leave off the "P" and it won't pop the float off the stack.
| Code: | aobscan(Stamina,F3 83 C4 10 39 36 8B 46 14 D9 40 24 D9 5D D0)
alloc(newmem,$1000)
label(code)
label(return)
newmem:
fld dword ptr [eax+20]
fst dword ptr [eax+24]
//jmp return -- edited
code:
fstp dword ptr [ebp-30]
jmp return
Stamina+09:
jmp newmem
nop
return:
registersymbol(Stamina) |

| Oh wait. I just noticed you had a JMP RETURN in there. Remove the first one.

Correct. Which makes it so having the two FSTP doesn't cause a crash.
However, the game is putting your stamina value into [ebp-30] for a reason.
So by skipping that, who knows what issue you could cause down the road.
