getName

public String getName()

Description copied from interface: HasName

Return a user-visible, unique name for this class. This name may not necessarily be globally unique, but must be unique across all objects of this class. For example, having both a User and a Zone named “Lightning” is acceptable, but there may not be two users with the same name.

Specified by:

getName in interface HasName

Returns:

a user-visible string name for this instance

tick

public void tick(long currentTime,
                 long deltaTime)
          throws UserDeadException

Description copied from interface: AcceptsMetronomeTicks

This method is called periodically from the metronome thread. To save computation, it receives both the current time since epoch in milliseconds at the start of the global tick propagation, and the delta time since the previous metronome tick.

Specified by:

tick in interface AcceptsMetronomeTicks

Parameters:

currentTime - Time since epoch at the start of the global metronome propagation, as per System.currentTimeMillis()

deltaTime - Delta-time in milliseconds since the prior global metronome tick

Throws:

UserDeadException - if a user has died during this tick
