Eyy CubedCraft,

With the Skript addons you have skQuery, but that addon doesn't work, you need 'SkQuery Fork', You can download it at: https://www.spigotmc.org/resources/unofficial-skquery-fork-1-6-1-12.36631/

When installed you get the file name 'SkQuery Lime' that's the right addon for Skript.

I hope you'll install it for the server skripts.

Thx,
FFGames
