Glenn is a tool to make porting builds of self-created AM2R Mods to other platforms easier. This will only work with VM-mods of the Community Updates, neither YYC mods nor mods of the original AM2R 1.1 will work.
You need to have at least .NET Core 6 installed in order to run this.

First you need a zip of the self-created mod. If you're using GameMaker: Studio, you can just use the zip it created. If you're using UndertaleModTool you need to zip the files first (your files should not be in a subfolder in the zip!). After that, just feed it into this tool and, select if you want to have a port made for Windows, Linux, Android or Mac.
It will then create a new zip/apk in the directory next to the program, which can be used for Atomic.

To create Android builds, you need to have Java installed.

By default, the ports will use stock splash and icon images, however you are able to change those.

• Keep Game Maker: Studio documentation in mind, using any functions that only work on one OS or function differently on different OS could lead to the ports having unexpected behaviour or even crashing.
• Use / for folder seperation, instead of \. \ only works on Windows, / works on every OS.
• Every OS except Android will only write and read from "lowercase" inside of working_directory. This means, that if you create a directory called MyCoolDirectory and read from it with Game Maker functions, it will actually create the directory mycooldirectory instead and read from there. This will only become a problem if you create files/folders outside of Game Maker. If you do so make sure that those are all in lowercase! As Windows is case-insensitive, it doesn't care for the case of files.

• Don't write to the asset folder. Linux is distributed as an AppImage, which makes that whole directory read only and such operations would lead to a crash. Create the files you need in working_directory on game boot if they don't exist, and then write to working_directory instead. This will create the files and read from them in ~/.config/<mygame>. Do not ship those files in the asset folder if you're planning to write to them.

• The following functions will crash the game if you'll use them:
  • immersion_play_effect and immersion_stop, font_replace. Make sure to either create an OS check before using those, or don't use them entirely. AM2R uses these by default, make sure to remove them or create an OS check!

• Due to Android being extremely sandboxed, users are unable to get files if you save something to working_directory.
