Help/Support How to make a int version return false in IDA?

hi,

 

So I got this function:

 

Coins - (int)cheated
__text:0003F99C
__text:0003F99C ; int __cdecl -[Coins cheated](struct Coins *self, SEL)
__text:0003F99C __Coins_cheated_
__text:0003F99C                 MOV             R1, #(_OBJC_IVAR_$_Coins.cheated - 0x3F9A8) ; int cheated;
__text:0003F9A4                 ADD             R1, PC  ; int cheated;
__text:0003F9A6                 LDR             R1, [R1] ; int cheated;
__text:0003F9A8                 LDR             R0, [R0,R1]
__text:0003F9AA                 BX              LR

 

Iknow I could MSHook this, but I wanna practice IDA..

So.. how would I return the int to 0?

 

I've no idea which one I have to change..

 

I thought the first MOV to MOV R1, #0 but I don't think it worked..

 

help would be great!

Use MOV R0, #0 (00207047)

i.e mov r0, #0 then bx lr. 

LDR             R0, [R0,R1] is your coins cheated i think
