As the size and functions of the game continue to superimpose, the data in the game becomes more and more complex, which includes not only data such as game archives generated by players, such as the number of levels, gold coins, etc., but also game configuration data, such as each off configuration. Although Unity provides PlayerPrefs for storing user data, it is only suitable for small amounts of data. Once the data becomes complex, PlayerPrefs becomes a disaster.
NoSQL database
For projects that require clients to store data, a local database is the optimal solution in this case. There are various types of data that need to be saved in Unity , and many of them are asset content and not just binary. NoSQL databases are obviously more suitable for Unity. LiteDB is such a local database. It is 100% based on C# development, free and open source, and can be directly imported into Unity for use. .
1. Import Unity
1. Use VS to open the Unity project.
2. Enter the Nuget package manager VS to find the tool--Nuget package manager--package manager console
3. Install the LiteDB installation script
Install-Package LiteDB -Version 5.0.11
Enter and press Enter to install
4. Import Unity project
Just use Nuget to download the latest package, and then import it into the Unity project. Import LiteDB.dll and LiteDB.xml together into the Plugins path of the Unity project.
5. Use Unity to regenerate the VS project
Delete the original VS project file in the project and regenerate it to generate a reference to the dll file.
6. Specify dependent scripts
In order to avoid Unity's code clipping, create link.xml under the Unity project path
2. Use LiteDB
Unity calls as follows
3. The final effect
