Help/Support Can't set watchpoint in gdb

[MayhemLobbiez 0 9]

I'm trying to set a watchpoint on ammo in gdb, when the address changes nothing happens in gdb... 

 

http://puu.sh/qAYCV/ce49804a6a.png is all that shows up in gdb when I shoot.. the address is for the ammo in the mag and not the reserve.. 

 

idk if my setup is wrong or what.

 

Running iphone 6 on iOS 9.0.2.. thanks for any help in advance, and sorry if I messed up writing this it's 9:40 am where I am and I haven't slept.

Bro ,  before continuing (typing c) -- you set watchpoints

 

So when the gdb loads fully,

 

just set watchpoint (watch *0xOFFSET)

 

then type c

watch *0xOFFSET

 

c

 

You watch the offset before you continue
Same goes for setting a breakpoing and setting a value to an offset

Don't even try to use GDB for watchpoints, they won't hit. Use LLDB, theres many tutorials here on setting it up

 

I recognize you from ic

I did type c after entering the watchpoint.. it wouldn't freeze my game though.. gonna try setting up lldb
