Class ConcurrentRouteFinder

java.lang.Object

cn.nukkit.entity.ai.route.SimpleRouteFinder

cn.nukkit.entity.ai.route.ConcurrentRouteFinder

All Implemented Interfaces:

IRouteFinder

@PowerNukkitXOnly
@Since("1.6.0.0-PNX")
public abstract class ConcurrentRouteFinder
extends SimpleRouteFinder

并行路径查找抽象类
实现了此类的寻路器应当提供完整的异步寻路支持
PNX中未使用此寻路方案，但保留以提供API
