Run managed code before Unity does!

Unity Doorstop

Doorstop is a tool to execute managed assemblies inside Unity as early as possible!

This repository is indented mainly for developers!
Developers should package Doorstop into their applications for the end-users.

Features

• Runs first: Doorstop runs its own code before Unity has an ability to do so.
• Configurable: A very basic configuration file allows to specify your own assembly to execute!
• Public domain! You are fully free to embed Doorstop into your application!

Building

To build, you will need:

• Visual Studio 2017 (2015 might work as well with some modifications)
• Visual C++ Toolset v140
• .NET Framework 3.5 or newer (only for the example, not used by the proxy)
• Python (only to generate proxy functions; not needed to build)

Clone, open in Visual Studio, select the platform (x86/x64) and build.

Custom proxy functions

Doorstop's proxy is flexible and allows to be load as different DLLs. You can modify which functions you want to proxy by adding/removing function names in Proxy/proxydefs.txt and running proxygen/proxy_gen.py ../Proxy/proxydefs.txt to generate an appropriate proxy functions.

The current set up allows to use the proxy for the following DLLs:

• winhttp.dll (All exports)
• iphlpapi.dll (Only GetIpAddrTable)

(WIP: Currently all build results are placed in separate folders; will be changed later)
