Class PositionCacheSystems

java.lang.Object

com.hypixel.hytale.server.npc.systems.PositionCacheSystems

public class PositionCacheSystems
extends Object

Handles the NPC PositionCache, including its updates and initialisation. The PositionCache is used by NPCs to quickly determine where other entities are in the world and is not updated every tick, but rather staggered in such a way that NPCs run their PositionCache updates in different ticks to reduce dips in performance.
