From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Sat, 27 Jan 2018 17:04:14 -0500 Subject: [PATCH] Add ArmorStand Item Meta This is adds basic item meta for armor stands. It does not add all possible metadata however. There are armor, hand, and equipment types, as well as position data that can also be added here. This initial addition should serve a starting point for future additions in this area.
