Subject: [PATCH] Maps shouldn't load chunks
|
|
|
|
Previously maps would load all chunks in a certain radius depending on
|
|
their scale when trying to update their content. This would result in
|
|
main thread chunk loads when they weren't really necessary, especially
|
|
on low view distances or "slow" async chunk loads after teleports or
|
|
other prioritisation.
|
|
|
|
This changes it to only try to render already loaded chunks based on
|
|
the assumption that the chunks around the player will get loaded
|
|
eventually anyways and that maps will get checked for update every
|
|
five ticks that movement occur in anyways.
