There have been some amazing games built using the Unity platform, but a core component missing in all these creations is a local database. A local database can persist game data and improve playability by not relying on network connections when they're dropped. This blog post explores how Unity and Couchbase, a NoSQL database, can work together to deliver outstanding experiences for mobile game players. By using Couchbase Mobile for Unity, developers can add a local database to their games, allowing them to save player data locally without depending on the network. This is achieved by referencing the Couchbase Lite frameworks in the GameController.cs file and creating a document named 'player_data' to store player data. The data can be retrieved, modified, and saved locally using Couchbase's Update method. Replication endpoints are also created to push local data to the remote server, allowing for synchronization of data between devices and the remote endpoint. This enables games to run smoothly even when network connections are dropped, resulting in a more robust and reliable gaming experience.
