What is a YY file?

YY files mostly belong to GameMaker Studio 2. An YY file is a GameMaker resource file that contains data in JSON format.
These files are used to store game components and settings, allowing the GameMaker Studio 2 engine to know what assets (like objects, sprites, and events) to load and how to configure them.
Key points sourced by FilExt.com:

Game resources: They keep definitions for game elements and assets.

JSON structure: Their text-based format makes them easier to read and, if needed, to edit with a simple text editor.

Integration: They are an integral part of GameMaker Studio 2, handling the configuration that builds the game.
