How to restore and save previous data in Unity.

Unity offers some methods to restore previously saved data.

1. Use PlayerPrefs: PlayerPrefs is a simple key-value storage method provided by Unity. It can be used to save and retrieve data. When restoring previous data, you can use the saved key-value pairs to recover the information.
2. In Unity, data classes can utilize serialization to save and load data. You can serialize an instance of a data class, save it to a file, then load and deserialize the saved file to restore the data class instance.
3. Utilize databases: If there is a need to store and retrieve large amounts of data, databases can be used for storage. In Unity, SQLite and other database libraries can be used to store data. Store the data in a database, and retrieve it when needed by reading the data from the database.

You can choose the appropriate method to recover the saved data based on your needs.
