Mod the Gungeon API

A plugin for BepInEx that adds some of Mod the Gungeon's functionality and also adds backwards compatibility for modders who want to port to BepInEx

Features

Mod the Gungeon API includes:

• Most of classic Mod the Gungeon's API features (adding items to loot tables, changing strings, replacing and adding textures, etc)
• A debug/cheat console (F2, ~, /)
• A debug log that records all Unity logging (F3)
  • Note: this log is disabled by default for performance reasons. It can be enabled in the config file (etgmodding.etg.mtgapi.cfg)
• A mods menu that shows all enabled plugins (F1)

• All ILManipulators used by Mod the Gungeon API now look for instructions that are less likely to be used by other mods in order to prevent potential breaks.
