Class PickupPredicate

java.lang.Object
  wyvern.lib.predicates.PickupPredicate

All Implemented Interfaces:

Predicate

public class PickupPredicate

extends java.lang.Object

implements Predicate

Filter to see if an object can be picked up. Right now it just checks to make sure the object isn't a nopickup or living object. Eventually it should check the player's strength, the weight of the object in question, and possibly other attributes (e.g. a Wiz/admin might be able to pick *anything* up).
