Subject: [PATCH] Optimize Entity distanceToSqr
|
|
|
|
This patch optimizes Entity#distanceToSqr call by using Math#fma which is around 1.2x to 4x faster than original method,
|
|
avoids multiple casting in Entity#distanceTo, using Math#sqrt directly instead of Mojang's Mth#sqrt. Additionally, this patch makes
|
|
these methods more able to be inlined by the JIT compiler.
