Subject: [PATCH] Do crystal-portal proximity check before entity lookup
|
|
|
|
This adds a very cheap distance check when an end crystal is placed.
|
|
|
|
Attempting to respawn the dragon, which involves looking up the end crystal
|
|
entities near the portal, every time an end crystal is placed, can be slow on
|
|
some servers that have players placing end crystals as a style of combat.
|
|
|
|
The very cheap distance check prevents running the entity lookup every time.
