oldGamemode-Plugin
This super cool and lightweight plugin for Spigot and Bukkit servers allows you to use the /gamemode command the old and cool way!
This plugin is designed to replicate the exact behaviour of the vanilla command but also allowing the usage of the old numeric game modes and the shorter /gm command.
(With the limitation that only English is supported)
Download the .jar: https://github.com/3urobeat/oldGamemodePlugin/releases/latest
...and put it into the plugins folder of your Spigot/Bukkit server. Done!
Usage
Type /gm or /gamemode in the chat to see all options in the auto completion.
Versions:
This plugin was tested on 1.16 - 1.20 but should also work on other versions.
