how to hook void offsets? not for mod, but for gg script.

[dede444]

hi, i have a problem with hooking void offsets, for example 

public void 0x58D8CC EnterPassword()

So my goal is, to hook that offset so i can write anything into password window and join private session with players

I know there is like a trick, but its only for moded apk and i want to make gg script for that. I have already offset hooker script which can easily patch public static offsets, but not public void

Have somebody a gg script like void offset hooker or something like that? Please help me guys:-)

Based on that method name EnterPassword you can not really tell if it is the one performing the check or not, maybe it is just used in another method that are actually performing the comparison of password. so if i was you i will look for name that are actually more meaningfull like CanJoin, IsPasswordCorrect, IsAllowed, and so on ...
if you have a pc you can plug on that method using frida and check if it is being called or not, if you dont have a pc you can use frida with termux

how can i check the offset from the game in termux or frida, explain pls

it doesnt work, because its void offset which cant be edited , it works only for static or withoid void offsets, thats why i need somebody who can help with that, but still thanks for that method anyways

Find the changed value (trace through gg), then get the address, get the initial value from lib calculate the distance from the initial lib to the changed value. Finished.

That enter password 

What you want for enter password? 

so logically, if i patch this offset, i can type anything into room with password so i can join players private room, u understood. but its not patchable with true or false or arm or hex because its a frickin void offset which cant be patch or else (returned). i know you can patch void offsets for mods, but i want patch it for gg script

You know about frida ?, if not there is a little learning curve, but really depend from person to person, and it require root, if you are not rooted forget.
there is a good repo to get you started https://github.com/kylesmile1103/Learn-Frida

Frida on mobile android 

Just use jshook or simplehook 

Required root and lsposed

gg can't create functions like mod menus, but you can find a suitable void to hook them up
