Will this (or another) plugin work on NPCs? Specifically, I'm looking for zombie hordes / murderers to spawn randomly around the map.

This plugin provides the API that other plugins need to support.

Is there a way to tell which plugins support it today?

There should be no plugin to support it...lol😅

Gah. I'm not being clear, and you, my fren, are being _very_ literal. What plugins that spawn NPCs (murderers in my case) make use of it?

BTW, it works great for player spawns. Thank you for creating it. 😄
