Field Detail

type

public Type type

Type of object at this location.

className

public String className

If type == Type.CREATURE, this is the class name of that creature. Otherwise, null. This is provided only for debugging. It is null unless security is disabled on the simulator to prevent creatures from colluding to throw matches.

classId

public int classId

Class ID (versus object ID) for the kind of object observed. The constants for this are defined in Creature. This can be used to distinguish creature types, since each creature class is assigned a unique ID at the beginning of the trial. For example, you could use this to react differently to FlyTraps, Apples, and unknown adversary creatures.
