A modding platform for Enter the Gungeon by Dodgeroll Studios, published by Devolver Digital.

By itself, nothing except a title screen. This is a mod loader - intended to be a base for mods to run, not a mod by itself.

If you're interested in the actual details, you can check the "For developers" section below. To simplify it, you run the installer, which modifies the game to insert all of this code into it. Then, when you start the game, ETGMod is started "inside" of it, with the ability to access anything from the game. It'll then start loading mods and doing all of the things it needs to do.

You can check the members of the Mod the Gungeon GitHub organization here. Note that, while there are 5 people there, 2 have officially quit the project while others remain mostly dormant. In other words, at this moment I'm pretty much the only person working on ETGMod.

Currently, the master branch (the branch you're seeing above) of this repository houses a version of ETGMod dubbed "ETGMod Reloaded". ETGMod Reloaded is a mod rewritten completely from scratch, with almost no code taken from the original ETGMod. The version that's currently available in the installer is an outdated version of the old ETGMod that was updated only to run on the latest Gungeon update (but it doesn't even have its new items as give command IDs).

ETGMod Reloaded has moved away from C# mods in favor of Lua mods. This, while slightly complicating the code, allows for a greater amount of control over mods by ETGMod and makes writing mods a lot easier. For example, I was able to implement the ability to reload mods without restarting the game, saving both the mod developers' and the end users' time. Mods are now also sandboxed, so that they can't just delete all of your files.

Since it's a work in progress, there isn't even a beta release yet. If you think you'll be able to do it, you can try building this repository (use the build.sh script or the build.bat script [NOTE: the build.bat script isn't finished yet]; you'll need to have Visual Studio or Mono installed). Then you can select the resulting ETGMOD.zip in the Advanced tab in the installer, install, and have fun.

The LICENSE_ETGMOD file contains the licenses of the projects used by ETGMod. If an external project is used by ETGMod and its license is not in LICENSE_ETGMOD, then it is an oversight and I ask you to report it on the issue tracker.

Dodgeroll is fully aware of ETGMod's existence and goals. For the foreseeable future, there shouldn't be any worries about whether ETGMod would be forced to have its development stopped.

ETGMod Reloaded is WIP, so no tutorials yet. Sorry!

• Very WIP API reference (doesn't have ETGMod classes yet, the look and feel will change soon)
• Discord channel
• Comparison between the Lua bindings that ETGMod uses, upstream Eluant and NLua.
• My barely-updated blog which contains some techniques and tools used by ETGMod
