Help/Support IDA Function what should be changed?

[Pradeep6868 5k]

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:

 

 GameStats$$CoinsInAirIncrement          ; CODE XREF: CoinManager$$RewardCoin+104↑p
__text:0000000100368B48                                         ; Game$$RewardCoin+50↑p
__text:0000000100368B48                                         ; DATA XREF: ...
__text:0000000100368B48
__text:0000000100368B48 var_s0          =  0
__text:0000000100368B48
__text:0000000100368B48                 STP             X29, X30, [SP,#-0x10+var_s0]!
__text:0000000100368B4C                 MOV             X29, SP
__text:0000000100368B50                 LDR             W8, [X0,#0x7C]
__text:0000000100368B54                 ADD             W8, W8, #1
__text:0000000100368B58                 STR             W8, [X0,#0x7C]
__text:0000000100368B5C                 MOV             X0, #0
__text:0000000100368B60                 MOV             X1, #0
__text:0000000100368B64                 BL              MissionsManager$$get_Instance
__text:0000000100368B68                 CBZ             X0, loc_100368B84
__text:0000000100368B6C                 MOV             W1, #0x4A
__text:0000000100368B70                 MOV             W2, #1
__text:0000000100368B74                 MOV             W3, #0xFFFFFFFF
__text:0000000100368B78                 MOV             X4, #0
__text:0000000100368B7C                 LDP             X29, X30, [SP+var_s0],#0x10
__text:0000000100368B80                 B               MissionsManager$$PlayerDidThis

I though the 'LDR W8, [X0,#0x7C]' could be hacked or 'STR W8, [X0,#0x7C]'

 

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

 

any help?

 

Thanks in advance,

Well, the function says CoinInAirInrement. 

I would think off a ADD then. Not sure by how much coins increase whenever you're in air? But if it's +1, then you definitely wanna hack the ADD.

 

Else hack the LDR or the STR with the variable in it. See in the dump.cs what the 0x7C variable holds.

If you have some time can you help with the same kind of hack for another game? Say Toram online or SOAIf?
