I made this myself. It uses a location code, such as: A1, A2, B1, or B2. After that, there is a on/off code that uses 1 for on and 0 for off. For example: A11 is on, and A10 is off. This code is used to save levels in some other games, like Geometry Dash Scratch, or Super Mario Maker Scratch. Some codes are stored on a cloud variable, which must need a unique/encrypted code.
