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).
