This script basicaly change the float value ( trove.exe+D9D4A0 = 0.009999999776)
Float Value: 0.009999999776
to
Float Value : 1
Script :
Code: Select all
define(address,trove.exe+4B4CCA)
define(bytes,D8 0D A0 D4 61 01)
[ENABLE]
aobScanModule(MyCheat3, Trove.exe, D80Dxxxxxxxx8BE55DC3D945FC8BE55DC3CCCCCCCCCC558BEC83EC6056)
assert(MyCheat3, D8 0D)
registerSymbol(MyCheat3)
alloc(newmem, 0x100)
label(code)
label(return)
label(SavedBytes)
registerSymbol(SavedBytes)
label(newValue)
newmem:
code:
fmul dword ptr [newValue]
jmp return
SavedBytes:
readMem(MyCheat3, 6)
newValue:
dd (float)1
MyCheat3:
jmp newmem
nop
return:
[DISABLE]
MyCheat3:
readMem(SavedBytes, 6)
dealloc(newmem)
unregisterSymbol(MyCheat3)
unregisterSymbol(SavedBytes)
after enable script :
this
Code: Select all
4F2D0000 - D8 0D 11002D4F - fmul dword ptr [4F2D0011]
create this "
4F2D0011" and no change the float
0.009999999776 to
1

Your multiplying the value not setting it. Instead of:
Code: Select all
//...
fmul dword ptr [newValue]
//...
Try something like this, that replaces the value with a float value of one:
Code: Select all
//...
fstp st(0) // pop the current value off the FPU stack.
fld1 // load a value of 1 onto the FPU stack.
//...
EDIT:
And just to note. 0x4F2D0011 is the address of "newValue" so it is multiplying using the "newValue" and thus the loaded value won't be changed. In case that's actually what you're going for.

thanks for reply.
new script :
Code: Select all
define(address,trove.exe+4B4CCA)
define(bytes,D8 0D A0 D4 61 01)
[ENABLE]
aobScanModule(MyCheat3, Trove.exe, D80Dxxxxxxxx8BE55DC3D945FC8BE55DC3CCCCCCCCCC558BEC83EC6056)

registerSymbol(MyCheat3)
alloc(newmem, 0x100)
label(code)
label(return)
label(SavedBytes)
registerSymbol(SavedBytes)
label(newValue)
newmem:
code:
fstp st(0)
jmp return
SavedBytes:
readMem(MyCheat3, 6)
newValue:
dd (float)1
MyCheat3:
jmp newmem
nop
return:
[DISABLE]
MyCheat3:
readMem(SavedBytes, 6)
dealloc(newmem)
unregisterSymbol(MyCheat3)
unregisterSymbol(SavedBytes)
i tryed not working

You only pop the value, you still never set it with that.
Code: Select all
define(address,trove.exe+4B4CCA)
define(bytes,D8 0D A0 D4 61 01)
[ENABLE]
aobScanModule(MyCheat3, Trove.exe, D80Dxxxxxxxx8BE55DC3D945FC8BE55DC3CCCCCCCCCC558BEC83EC6056)
assert(MyCheat3, D8 0D)
registerSymbol(MyCheat3)
alloc(newmem, 0x100)
label(code)
label(return)
label(SavedBytes)
registerSymbol(SavedBytes)
newmem:
code:
fstp st(0)
fld1
jmp return
SavedBytes:
readMem(MyCheat3, 6)
MyCheat3:
jmp newmem
nop
return:
[DISABLE]
MyCheat3:
readMem(SavedBytes, 6)
dealloc(newmem)
unregisterSymbol(MyCheat3)
unregisterSymbol(SavedBytes)

How do I set it now to 1 instead of 0.009999999776?
add on script this?

That's what the FLD1 does, it loads a floating point value of 1 onto the FPU stack. Thus whatever the value was is popped (removed) form the FPU stack, then you load (replace) it with a value of 1.
EDIT:
Basically using one or zero is so common that there's an instruction for both. I.e.:
fld1 and
fldz plus some others as well.
