Subject: [PATCH] Entity Tracking Ranges
|
||||
|
||||
This will let you configure how far to track entities in range from players, so that the entity does not render on the client if out of this range.
|
||||
This has multiple benefits:
|
||||
|
||||
1) Less bandwidth. Not sending update packets for entities that are not even close to a player, or even close enough to clearly see.
|
||||
2) Less lag by maps in item frames - Default range is 160 blocks... Many players can track that item frame and cause lag and not even see it.
|
||||
3) Less lag in general - Less work for the server to do
|
||||
4) Less client lag - Not trying to render distant item frames and paintings and entities will reduce entity count on the client, which is major for shop/town worlds which may use tons of item frames.
