A tool to decompile protobuf classes compiled by [protoc](https://github.com/protocolbuffers/protobuf), from il2cpp compiled CIL assemblies back into .proto definitions.
|
||||||
|
|
||||||
|
This branch was created as a proof-of-concept using [the development branch of LibCpp2Il](https://github.com/SamboyCoding/Cpp2IL/tree/development/LibCpp2IL) to parse the game assembly and metadata directly, without the intermediate step of generating dummy DLLs.
|
||||||
|
|
||||||
|
I offer no guarantees that this branch functions 1:1 with master, it may explode.

|
global_metadata_path The path to the global-metadata.dat file.
|
||||||
|
unity_version The version of Unity which was used to create the metadata file or alternatively, the path to the globalgamemanagers or the data.unity3d file.

- The `Tool` parameter of `GeneratedCodeAttribute` is not compared against when parsing gRPC service methods, which may cause false positives in the event that another tool has generated methods in the service class.
