Astra is a mod for The Binding of Isaac: Repentance, written in TypeScript using the IsaacScript framework.
If you are a developer, or the mod is not yet uploaded to the Steam Workshop, you can play the mod by compiling the TypeScript code into a "main.lua" file. Perform the following steps:
- Download and install Node.js (Windows Installer .msi, 64-bit).
- Download and install Git (64-bit Git for Windows setup).
- Download (or clone) this repository:
- Click on the "Code" button in the top-right-corner of this page.
- Click on "Download ZIP".
- Unzip the zip file to a new directory.
- Open up the repository folder and double-click on the
run.shscript. If prompted, choose to open it with Git for Windows. You will see a Git Bash terminal window open. - The script might ask you some questions, like which save file that you use for testing.
- If the script is successful, you will see "Compilation successful." (You can continue to leave the terminal window open; it will monitor for changes in your project, and recompile if necessary.)
- Completely close Isaac if it is already open, and then open the game again, and the mod should be in the list of mods. You can now play or test the mod.
