We are currently moving Rising World to the Unity engine, so the "new version" will no longer be based on Java. Of course this also has an impact on existing servers and their configuration.
Currently the new version is available in a beta branch on Steam (the "unity" beta branch), but it will replace the Java version in the near future (i.e. the new version can be considered a "huge update"). Here is an overview of the server-related things that will change:
- The new version no longer uses Java
- The dedicated server files requires more disk space (up to 1-2 GB)¹
- The new version no longer has MySQL support
- The new version requires less ports
- Start arguments (launch options) are different
- Server.properties (config) file is different
- Old worlds won't be compatible with the new version²
- You cannot set the max. server RAM via config or launch option³
¹ Other system requirements (RAM etc) stay mostly identical
² This means players will have to create a new world
³ The server will allocate more RAM automatically if required. If you don't want this, we recommend to run the server in a container (e.g. Docker, LXC etc)
If you don't want the new version to get installed automatically as soon as it becomes available and want to stay on the Java version, we recommend to enable the legacy beta branch on Steam
This branch is identical to the current public branch (so it's safe to switch to this branch now), and this branch won't change when the new version goes live. This gives you enough time to upgrade to the new version.
