Hi, everyone. I'm trying to hook an il2cpp method, i.e. Call it, but I'm unsure about how to do that.

For example, there is a method as shown:
demon1.png


What I would like to do is call the method 'AddRuby()' but I don't know how to call il2cpp methods. Can anyone help me out? Thanks!

The second example of a method, this time with parameters:
demon2.png

to call this function just set a function pointer:
C++: 
void (*AddRuby)(void *instance) = (void (*)(void*))reBase(address);

Make sure to define the address only when the library is loaded.
So i suggest you to split the definition of the pointer.

Thanks for the reply! Appreciate it. Although, I haven’t really dabbled much in C++ yet, and I’m fairly new to hooking, so how would I go about loading this hook when a game is loaded? I’m more of a C# / Windows reverser myself.

to check if a library is loaded just:
1) Create a new thread
2) inside the new thread just sleep until it doesn't find a new library. (Use the function provided from KittyMemory)
C++: 
do {
    sleep(1);
} while(!isLibraryLoaded("libil2cpp.so"));
or use
C++: 
while (!isLibraryLoaded("libil2cpp.so")) {
    sleep(1);
}

That’s very well and great until half of the steps of the tutorial are missing, and they reference libraries that aren’t even named. Yeah, thanks. Also, if you’re gonna be like that, don’t bother

AS sometime can be annoying, use cmd compile is much better

Android Studio IDE has become more buggy and shit, stuck on loading devices, invalid syntaxes even it still able to compile, random freezing, high CPU usages on idle, and many more. Maybe i'm dumb, but honestly it works like shit. Invalidate caches and full reinstall doesn't help much. i'm tired...

Noob ? So u assume i dont have "approve modder" tag means i dk shit ? Ive been releasing mod since 2018 and I dont have to post here bcs most of them share mod public here alrd shared it for me. Okay i admit im noob, knowledge is vast still learning until now

"Dont using this shit set player nickname by parameters, use CreateString."
Why dont u explain your statement here ? To do a mod with monoString ofcz u will need createstring for function pointers , it also can be done to any function type return or param
