Subject: [PATCH] Optimize sending packets to nearby locations (sounds/effects)
|
|
|
|
Instead of using the entire world or player list, use the distance
|
|
maps to only iterate players who are even seeing the chunk the packet
|
|
is originating from.
|
|
|
|
This will drastically cut down on packet sending cost for worlds with
|
|
lots of players in them.
