Wsmpcore

A configurable Paper SMP core for 1.21.11 — player utilities, staff tools, PvP controls, anti-exploit rules, an ore shop, and an addon API in one plugin.

Wsmpcore provides the practical systems an SMP needs without forcing a huge dependency stack. Configure feature toggles from the operator GUI, then fine-tune values, materials, limits, messages, and lists in config.yml or through the built-in settings controls.

Installation

Install Paper 1.21.11 with Java 21.
Put Wsmpcore-1.1.1.jar in the server's plugins/ directory.
Restart the server.
Use /wsmpcore as an operator.
Edit plugins/Wsmpcore/config.yml when you need detailed configuration, then run /wsmpcore reload.

Addon API

Wsmpcore registers com.wsmpcore.api.WsmpcoreApi through Bukkit's ServicesManager. Addons can use it to read feature states, manage PvP flags, access homes, and inspect combat tags.

The companion Wuhc plugin uses this API as a required dependency for UHC and Battle Royale games.
