R2API – a modding API for Risk of Rain 2

About

R2API is a modding framework for other mods to work in, providing centralized and simplified APIs for Risk of Rain 2. This helps keeping mods compatible with each other.

At it's core, R2API should not change how the game behaves without any other mod installed. The only change is to keep mods out of quickplay and prismatic trials by request of the Hopoo Games team.

Installation

The contents of R2API should be extracted into the BepInEx folder, such that the files inside the monomod folder in the zip sit in the monomod folder in BepInEx and the files and folder in plugins in the archive is inside your plugins folder.

A succesful installation should look like this:

Developing

A lot of documentation is in the included xmldocs, and further information may be on the dedicated R2API wiki. Do not hestiate to ask in the modding discord too!

Bleeding Edge

Unless you are a mod developer, you won't need this.

Want to get the latest versions of R2API? The latest bleeding edge builds of master are hosted on Azure, and may be downloaded using the Artifacts drop down menu.

Note that such builds may be unstable.
