From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Caleb Bassham Date: Fri, 28 Sep 2018 02:32:19 -0500 Subject: [PATCH] Call player spectator target events and improve implementation Use a proper teleport for teleporting to entities in different worlds. Implementation improvements authored by Spottedleaf Validate that the target entity is valid and deny spectate requests from frozen players. Also, make sure the entity is spawned to the client before sending the camera packet. If the entity isn't spawned clientside when it receives the camera packet, then the client will not spectate the target entity.
