Subject: [PATCH] PreCreatureSpawnEvent
|
|
|
|
Adds an event to fire before an Entity is created, so that plugins that need to cancel
|
|
CreatureSpawnEvent can do so from this event instead.
|
|
|
|
Cancelling CreatureSpawnEvent rapidly causes a lot of garbage collection and CPU waste
|
|
as it's done after the Entity object has been fully created.
|
|
|
|
Mob Limiting plugins and blanket "ban this type of monster" plugins should use this event
|
|
instead and save a lot of server resources.
|
|
|
|
See: https://github.com/PaperMC/Paper/issues/917
