ggil2cpp's Introduction

Il2cpp Module for GameGuardian

About Module

This script is only needed to make it easier to work with Il2cpp. This script works through the program GameGuardian. With the help of the module, you can get information about the method or class that interests you. This script is not positioned as a dumper, and is only needed to simplify working with Il2cpp.

The module has support for the Lua plugin for VS Code, that is, some functions have a description that this plugin can display.

The script is divided and available for assembly. You can also use an already built version from the build folder or from the Releases tab. Script is built using the luabundle library.

All documentation about the module is available on the wiki

ggil2cpp's Issues

HybridCLR

Background

Games now are starting to adapt HybridCLR, as it claims: 'high performance, low memory'. It introduces some AOT changes of Unity into 'AOT + Intrepreter' to aim for 'C# Hot Update Technology'. This HybridCLR is also called as 'hotfix update': HybridCLR

Problems

Currently, GGIL2CPP fails to obtain classes, fields, and methods information directly from the game memory. It also breaks all IL2CPP dumpers, even that executed in runtime, like: Zygisk-Il2CppDumper. Pointing fields / methods with specific offset still works, looks like the changes breaks the 'string' correlation as most dumpers also include function names, etc.

*This issue is reserved as templates once the workaround to this issue is widely adopted.

The module cannot find the library on Android Emulator

help

Excuse me, how to enter any address to get the class and so on?

Full dump.cs

Is it possible to generate full dump using GG, like Zygisk-Il2CppDumper does? I wanted to dump protected game but it crashes with zygisk module, Perfare has yet to respond. I don't care if the GG process is really slow

The module does not search for a method by offset

There are errors in the offset search that cause errors

Field not found

Hello, I tried to use your Il2cppApi tool to query fields in the game named Arkights. Many different fields were queried, but none of them could be found

report errors

Hello, sir, I used this on the Android 10 mobile phone, and reported an error in the modifier. The following is what I reported an error.
