Optimise nearby player retrieval
Instead of searching/testing every player online on the server, we can instead use the nearby player tracking system to reduce the number of tests per search.

Subject: [PATCH] Optimise nearby player lookups
|
||||
|
||||
Use a distance map to map out close players.
|
||||
Note that it's important that we cache the distance map value per chunk
|
||||
since the penalty of a map lookup could outweigh the benefits of
|
||||
searching less players (as it basically did in the outside range patch).

Subject: [PATCH] Optimise nearby player retrieval
|
||||
|
||||
Instead of searching/testing every player online on the server,
|
||||
we can instead use the nearby player tracking system to reduce
|
||||
the number of tests per search.
