What is a .YY file?

A .YY file is a special kind of file used by people who make games using a program called GameMaker Studio 2, which is made by YoYo Games. This file doesn't contain the actual pictures, words, or code for the game, but it has important information (metadata) about these parts of the game in a format called JSON. JSON is a way to organize and store information so that both humans and computers can understand it easily. For example, if a game developer adds a new character or level to their game, GameMaker Studio 2 will create a .YY file for that new part. This file helps the program understand how the new part fits into the game.

To open and work with a .YY file, you can use several different programs: 1. **YoYo Games GameMaker Studio 2**: This is the main program that uses .YY files. It's specifically designed for creating and editing games, so it understands how to read and use the information in these files to help you build your game.

2. **Microsoft Visual Studio Code**: This is a powerful editor for coding that can also open .YY files. While it's not specifically made for GameMaker, it's very good at working with JSON data and can be a helpful tool for more advanced editing or for developers who prefer its interface.

3. **Any text editor**: Because .YY files are in JSON format, you can open them with any basic text editor like Notepad on Windows, TextEdit on Mac, or other similar programs. However, using a simple text editor means you won't have the specialized tools and features that GameMaker Studio 2 or Visual Studio Code offer for understanding and editing the file's content in the context of game development.

In summary, .YY files are important for game developers using GameMaker Studio 2 because they hold essential information about the game's resources. These files can be opened and edited with the GameMaker program itself, a coding editor like Microsoft Visual Studio Code, or even just a basic text editor, depending on what you need to do with the file.
