Class Simulator

java.lang.Object
  simbad.sim.Simulator

public class Simulator

extends java.lang.Object

The Simulator class. It manages the list of agents and performs the simulation steps. For each agent a simulation step is is as follow:

update sensors

call agent performBehavior

update position

In normal operation the steps are triggered by a timer event.
The Simulator class also provides a Background Mode with limited rendering. This mode is mainly useful for batch simulation ( ie genetic algorithms). See Also Simbatch class. Cooperates with: World, PhysicalEngine
