BepInExPack

BepInEx Framework

This is the pack of all the things you need to both start using mods, and start making mods using the BepInEx framework.

To install, extract contents of the inner BepInExPack to the gamefolder, such that the winhttp.dll file sits right next to RiskOfRain2.exe.

The zip looks like:

\BepInExPack    <----- move the contents of this folder
manifest.json
readme.md
icon.png

What each folder is for:

• BepInEx/plugins - This is where normal mods/plugins are placed to be loaded. If a mod is just a NAME.dll file, it probably goes in here. For your own organisation, consider putting them inside folders, eg: plugins/ActualRain/ActualRain.dll

• BepInEx/patchers - These are more advanced types of plugins that need to access Mono.Cecil to edit .dll files during runtime. Only copy paste your mods here if the author tells you to.

• BepInEx/config - If your plugin has support for configuration, you can find the config file here to edit it.

• BepInEx/core - Core BepInEx .dll files, you'll usually never want to touch these files (unless you're updating manually)

What is included in this pack

BepInEx 5.4 - https://github.com/BepInEx/BepInEx This is what loads all of your plugins/mods.

Customized BepInEx configuration BepInEx config customized for use with RoR2.

Changelog

Available in the CHANGELOG.md file

    • Ensure the old non working FixPluginTypesSerialization dll do not get loaded.

• 5.4.2114

  • RoR2 BepInExPack specific changes :
    • mono.cecil: use a custom mono.cecil dll because the Monomod version used is actually depending on 0.11 and we need to hack the dll version number so that Unity 2019.4.37 is happy and load the assemblies that depends on Mono.Cecil

  • RoR2 BepInExPack specific changes :
    • BepInEx.GUI: Ensure remaining old dll in the patchers folder doesn't get loaded by BepInEx Preloader.
