Help/Support How to write a hook using Android Hooking Template?

[CeeCeeCee 0 Xiaomi Redmi 3S 6.0.1]

Hi masters,

I am quite new to this site and I am learning a new way to mod Android games, which is called Hooking functions (I am not sure if I call it right).

As I read the instruction in this GitHub project, at the Creating the libhook.so step (step 2 - Inside "hook.cpp", you'll write your hooks.), I just don't know how to write it (I am completely new to this). I have searched many websites to find a clear instruction for this but there is no one.

So now I am here to ask for your help.

Could anyone please give a sample hook (on Android, of course) when I write in the hook.cpp? Or a screenshot is also pretty good!

For example, in the picture below, I want to GetMoneyTotal (void) at offset 000BBFE8, then what should I write the code?

My English is bad and I don't know if I ask a properly question. I just want to learn new things from this heaven of moddings.

It would be great if any one can help. I am greatful about that.

Hope that @DADi would have a look at this thread and help.

Thanks in advance!

I have read that thread. But what I want is a complete sample hook to see how it looks like, or something else needed to make the mod works

but I am using Android Hooking Template. is that the same as MSHook?

in MSHook, there is a tweak while the one I am using has a hook.cpp file and I need to write hooks in it

may you give me a sample hook?

ARM V7:


#include <jni.h>
//#include <android/log.h>
#include "libs/KittyMemory/MemoryPatch.h"
#include <libs/Substrate/CydiaSubstrate.h>
#include <memory.h>
#include <dlfcn.h>
#include <cstdio>
#include <cstdlib>
#import "include/Utils.h"

//Struct for patches
struct My_Patches {

    MemoryPatch AddCoin, AddDiamond;
	
} my_cool_Patches;

int (*old_coin)(void *instance);
int (coin)(void *instance) {
	if(instance!=NULL) {
		return 999999;
	}
	return old_coin(instance);
}

int (*old_diamond)(void *instance);
int diamond(void *instance) {
	if(instance!=NULL) {
		return 9999;
	}
	return old_diamond(instance);
}

__attribute__((constructor))
void libhook_main() {

    while(libBase == 0) { 
        libBase = get_libBase(libName); 
        sleep(1); 
    }   
	
	//KittyMemory patch example.
	my_cool_Patches.AddCoin = MemoryPatch(libName, 0xC9C448, "\x3f\x12\x04\xe3\x0f\x10\x40\xe3", 8);
	my_cool_Patches.AddCoin.Modify();
	
	my_cool_Patches.AddDiamond = MemoryPatch(libName, 0xC9C4F4, "\x0f\x17\x02\xe3", 4);
	my_cool_Patches.AddDiamond.Modify();
	
	//Usual Hook example.
	MSHookFunction((void *)getRealOffset(0xC9A8DC), (void *)coin, (void **) &old_coin);
    MSHookFunction((void *)getRealOffset(0xC9AB98), (void *)diamond, (void **) &old_diamond);
}

------------------------------------------------------------------------------------------------------------
And For ARM V8:

Just Edit This Code :

From This:

MSHookFunction((void *)getRealOffset(0xC9A8DC), (void *)coin, (void **) &old_coin);
MSHookFunction((void *)getRealOffset(0xC9AB98), (void *)diamond, (void **) &old_diamond);

To THis:

A64HookFunction((void *)getRealOffset(0xEE218DC), (void *)coin, (void **) &old_coin);
A64HookFunction((void *)getRealOffset(0xEE21A98), (void *)diamond, (void **) &old_diamond);

I Write For You which one Arm V7 & which one Arm V8
And They Are not have change just a latest lines
