What if you could make events that happen on a schedule?
Cron is a tool that allows us to schedule events based on real-life time, such as "once every 2 weeks," "every 6 hours," or even "every Sunday night at midnight." It can also respond to in-game time, giving you precise control over when things should happen in the world. This makes Cron a powerful time-based trigger that can drive world events automatically.
Now here is where the real power comes in: Cron is the trigger, and Expand World Prefabs (EWP) is the reaction.
We will use Cron to determine when something happens, and then use EWP scripts to define what happens. For example, you might want copper nodes to respawn once a week to keep resources flowing in long-term servers. Or maybe you want to launch a world event on weekends, or refresh abandoned structures on a regular schedule. With this system, all of that becomes fully automated and entirely server-side.
But routines are not just for scheduled events. You can also use them to create custom devcommands that respond to manual triggers using Valheim’s global keys.
Here is how it works: when an admin sets a specific global key, EWP can be configured to detect that key being set and immediately run a script in response. This works even if the key was already set previously, meaning you can repeatedly trigger the same action. In practice, this turns the act of setting a key into a custom devcommand.
With this method, server managers unlock powerful new tools:
You can flip the server into maintenance mode, where all non-admin players are automatically kicked.
You can manually trigger a world cleanup, resource refresh, or a reset of custom content.
This combination of Cron and EWP gives you deep control over how your server behaves, both on a schedule and on demand. Your server can now respond to time, admin actions, or custom triggers in ways that simply weren’t possible before.
Let’s use this system to turn your Valheim world into a living, automated, and administrator-friendly environment where routines and commands are only limited by your imagination.
