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, either refer to installation guide on R2Wiki,

or 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

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)

What is included in this pack

BepInEx 5.4 - This is what loads all of your plugins/mods.

Customized BepInEx configuration BepInEx config customized for use with RoR2
