From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sun, 24 Mar 2019 00:24:52 -0400 Subject: [PATCH] Fixes and additions to the spawn reason API Expose an entities spawn reason on the entity. Pre existing entities will return NATURAL if it was a non persistenting Living Entity, SPAWNER for spawners, or DEFAULT since data was not stored. Additionally, add missing spawn reasons.
