advanced modding il2cpp question

[Matt_code_guy]

I had written some mods for a game, and as a result the developers started using IL2CPP. I am familiar with IL2CPP and how you go about modding it.

My question is if I know the implementation of the C# code, is there any way to inject it at the inspected offset.

let's say IL2CPPDumper reveals there's a method

// offset 0x12345678
public static void processSomeServerMessage() {

}

and I know that the implementation is:

// offset 0x12345678
public static void processSomeServerMessage(Message msg) {
  msg.forEach(msg => {
    //do something
  }
}

And I desire the implementation to be:

// offset 0x12345678
public static void processSomeServerMessage(Message msg) {
  ChatSingleton.addLine('some message');
  msg.forEach(msg => {
    //do something
  }
}

In this case I know the offsets, I know the current implementation and the desired implementation. Is there any way for me to convert my code to hex, and use a hex editor to insert it or am I limited to just changing values?

Well .. no you can't ... and yes you could do the same if you know c / c++ and hooking ... there is plenty of source codes in the internet just search in google .. that's all i can say

Im fine writing the code in C++ as well. So it is possible to hook C++ code?

Yes since il2cpp means IL code converted into c++
