Since version 0.5.6 it's possible to use MySQL instead of SQLite (dedicated server only). It's highly recommended to use MySQL when you're running a server with several players.
If you want to convert your old SQLite Worlds, you can use our small converter tool (we will release a gui version of it soon): https://download.rising-world.net/tools/converter.zip
Simply extract the zip and execute the jar file with these arguments:
java -jar converter.jar WORLDPATH IP:PORT USERNAME PASSWORD DATABASE
For example:
java -jar converter.jar "C://Rising World/Worlds/New World" 127.0.0.1:3306 root 123456789 newworld
To enable MySQL for your server, you have to change these settings in your server.properties file:
| database_mysql_connections | total number of simultaneous connections |
| database_mysql_database | database name |
| database_mysql_password | user password |
| database_mysql_user | user name |
| database_mysql_server_ip | mysql server ip |
| database_mysql_server_port | mysql server port |
| database_type | sqlite or mysql, in this case mysql |
Note: Before starting conversion, it's strongly recommended to create a backup of your world!
