This allows for direct re-development in the **Unity Editor**, and the projects can even run without modifications. UREngine has achieved significant progress in parsing most assembly instructions and linking with Il2Cpp, generating .CS files that closely resemble the original source code. **(UREngine's semantic parser removes initialization code and junk code from the engine)** 8 | 9 | ## Platform Support 10 | 11 | - Android (Arm64) 12 | - iOS (Arm64) 13 | - PC (To be determined) 14 | 15 | ### Cpp2CS Conversion Example 16 | **Original Code**: 17 | ![Original Code](https://raw.githubusercontent.com/IIIImmmyyy/UnityReverseEngine/master/source/ori.png) 18 | 19 | **IDA**: 20 | ![IDA](https://raw.githubusercontent.com/IIIImmmyyy/UnityReverseEngine/master/source/ida.png) 21 | 22 | **Il2Cpp Reversed to C#**: 23 | ![Il2Cpp to C#](https://raw.githubusercontent.com/IIIImmmyyy/UnityReverseEngine/master/source/back.png) 24 | 25 | ## Pending Developments 26 | ### Unfinished Parts of Cpp2CS Instruction Parsing: 27 | 28 | - VTable parsing; 29 | - Parsing of Struct type parameters; 30 | - Removal of junk code through reference counting; 31 | - Generic parsing; 32 | - Unknown. 33 | 34 | ### Resource Section: 35 | 36 | - Association of components and scripts; 37 | - Unknown. 38 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 咳咳.给自己打个广告 2 | ## [Android U3D手游安全中级篇] 3 | ## [https://github.com/IIIImmmyyy/u3dCourse](https://github.com/IIIImmmyyy/U3DGameCourse) 4 | 5 | - [README 中文](./README.md) 6 | - [README English](./README-en.md) 7 | # UnityReverseEngine 8 | Decompile APK/IPA To UnityProject 9 |

11 | **UnityReverseEngine**目前正处于开发阶段...（重构中...） 12 | 13 | ## 介绍 14 | UREngine是一个反编译引擎。用于还原Unity打包后的**APK/IPA**工程，可将打包后的文件**逆转为Unity工程**，可直接在**Unity编辑器上二次开发，甚至无需改动即可运行**。 15 | 目前UREngine已经实现了对绝大部分汇编指令的解析以及和Il2Cpp的关联，可将Arm64指令完整的并且最贴近源码的形式直接生成.CS文件。**(UREngine的语义解析器会去除引擎的初始化代码和垃圾代码)** 16 |
17 | 18 | ## 平台支持 19 | 20 | - Android APK (Arm64) 21 | - IOS IPA 22 | - PC(待定) 23 |
