Class Item

  group1.model.gameobject.GameObj
      group1.model.gameobject.item.Item

Direct Known Subclasses:

Mushroom

public abstract class Item
extends GameObj

An abstract "pickup" item. This should have some particular effect on Jeff when he touches it. Such effects in traditional games include: restoring health, obtaining a weapon, transformations, etc. Items may also have detrimental effects, such as poison, damage, bad transformations (such as shrinking), or instant death. (It is suggested that any item disappear once it is touched. This prevents it from being picked up multiple times.)
