need some help with CE code

originalcode:
fstp dword ptr [edi+eax*8+04]
pop edi

now what i want to do with this is have EAX which would be the "stored value"
The Acculmulator register. It can also be used as storage. <

now i know pop EDI means is going to take the value that is in edi "transfer the number" to something

but what i want to do is add the value of iunno 10 or somthing so EAX now reads EAX

alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
label(amount)
label(type_coins)


newmem:
pushad
mov [amount],(float)10 // the amount i want EAX to be


push [amount]
push type_coins
push 01
add esp,0c


popall

mov eax,-1000 // i am under the impression of it that this is the problem.
originalcode:
fstp dword ptr [edi+eax*8+04] // the code i need to edit.
pop edi


exit:
jmp returnhere


amount:
db 00 00 00 00
type_coins:
db 'coins'
db 00



this above is the code i have so far i just wonder how i would make it so i have 10 in EAX any tips or help? forgot to add the fact that right now all it does is freeze the value @ its current state 5 and if i build somthing or sell somthing it remains at one but still spends the coins so im not sure what i did wrong =(

so in a nutshell i want edi+eax*8+04 < to edit this so that it will
newmem:
pushad
mov [amount],(float)10
accept this.

3 days and nothing come on guys :D

Um if you just want to put 10 into eax then why don't you just do that. Like


push eax
mov eax, 10
pop eax

But that's not really what you are after I think, Because the FTSP is a mov pop, and the value in [] is edi+eax+4*8 I mean you could just break and find edi, eax and mov four to get the value of eax+4 add them and multiply but that's lot of work I would just replace it with your own label like

alloc(newmem,2048)

label(turnItOn)
label(originalCode)
label(WantedNumber)
label(DontWantedNumber)

registersymbol(WantedNumber)
registersymbol(DontWantedNumber)

[enable]
turnItOn:
fstp dword ptr [WantedNumber]
pop edi
jmp DontWantedNumber

WantedNumber:
dd (float) 10.0

DontWantedNumber:
fstp dword ptr [edi+eax*8+04]
pop edi

[disable]
originalCode:
fstp dword ptr [edi+eax*8+04]
pop edi

unregistersymbol(WantedNumber)
unregistersymbol(DontWantedNumber)

dealloc(newmem)

If its a multiplayer game you might want to add a cmp switch to check the player and make sure you are not also helping them. This is easy to do. Most games store you as the default player one on your console. So just search for a 1 on your turn and 0 on opponents turn if 2 player normally works. Or just 1 on my turn and not 1 on opponent. If this fails then try you as a 0 and not 0 for opponent. If not, get creative. Once you have this find the offset and get a good static address and just add it like this

AOBSCAN(Player, ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ??)
label(Player)
registersymbol(Player)

cmp [Player], (int)1 // if the player value you found for your turn is = to 1// compare Player to Number 1
jne DontWantedNumber
je WantedNumber
jmp originalCode

Blah blah. I think I covered your question. Only 7 years later.

Player:
dd (int)0
