Run In-Game Commands

KubeJS provides server-side methods that can run Minecraft commands directly.

You can use the global static class Utils, access its server property, and call runCommand.

Example:

Utils.server.runCommand('kill @e[type="item"]');

Each time this line runs, it executes the command and removes all dropped items.

However, runCommand prints feedback in chat. If you want to hide that from players, use:

Utils.server.runCommandSilent('kill @e[type="item"]');

This runs the command without chat output.

Tip: if you can get the server object from an event, use that server instance to call runCommand / runCommandSilent instead of Utils.server. This helps avoid hard-to-debug issues.
