Hey there,

 

I am trying to understand IDA Game Hacking, but I am not really getting it.

Did read all tutorials like 947845874 times...

 

I think this function is hackable:

bool __cdecl -[CurrencyWallet spendValue:](struct CurrencyWallet *self, SEL, unsigned int)
__text:00071F40 __CurrencyWallet_spendValue__           ; DATA XREF: __objc_const:00DAA128o
__text:00071F40                 PUSH            {R4,R7,LR}
__text:00071F42                 ADD             R7, SP, #4
__text:00071F44                 MOV             R4, R0
__text:00071F46                 MOV             R0, #(_OBJC_IVAR_$_CurrencyWallet._quantity - 0x71F52) ; unsigned int _quantity;
__text:00071F4E                 ADD             R0, PC  ; unsigned int _quantity;
__text:00071F50                 LDR             R0, [R0] ; unsigned int _quantity;
__text:00071F52                 LDR             R1, [R4,R0]
__text:00071F54                 CMP             R1, R2

I though the 'MOV R4, R0' could be hacked or 'PUSH {R4,R7,LR}'

 

I have this problem with like any game, I've no idea what to do...

 

any help?

 

Thanks in advance,

 

:)

You can NOP the

sub r1, r1, r2

or just hook the method:

%hook CurrencyWallet
- (bool)spendValue:(unsigned int)value {
   return YES;
}
%end

Hmm not working. Guess the function isn't hackable then?
