Features

All included features are listed below.
Features originating from other projects are carefully verified and updated as part of Gale.

• Allocate zero or one block destruction packets (original by vytskalt)
  Leaf: Reduce-block-destruction-packet-allocations.patch
• Cache Identifier toString and hashCode (original by OverwriteMC)
  Lazily cache Identifier toString() and hashCode().
  Leaf: Cache-identifier-toString-and-hash.patch
• Cache world generator sea level (original by jaskarth)
  This method is potentially called for every block in the chunk, so this will save a lot of registry lookups.
  Leaf: Cache-world-generator-sea-level.patch
• Check targeting range before getting visibility (original by PaulBGD)
  Check targeting range before computing visibility distance, because the latter is more expensive.
  Leaf: Check-targeting-range-before-getting-visibility.patch
• Check type before distance when testing targets (original by Taiyou)
  Check type before computing distance, because the latter is more expensive.
  Leaf: part of Optimize-SetLookAndInteract-and-NearestVisibleLiving.patch
• Delay canSee check in entity collisions
  Perform other checks before canSee, because the latter is more expensive.
  Leaf: Reduce-canSee-work.patch
• Don't iterate over empty tick effect collections ((original by hayanesuru)
  Leaf: part of optimize-tickEffects.patch
• Event-driven
  Update (and keep cached) values or take certain actions when the underlying conditions change, instead of calculating the value or considering the action every time it is requested.
  • Entity#playerPassengerCount
  • Mob#isLeashed
  • Mob#isPersistent
  • Mob#mustDespawnBecauseOfPeacefulDifficulty

• Inline player UUID comparison
• Initialize sensing with low capacity
  Most mobs only ever target at most 1 entity (typically a nearby player or a mob farm bait entity)
  so we create their sensing cache with an initial capacity of 2 instead of 16.
