public Input handle (Action action, UUID actor)

Processes a Move action. In the case of a basic Move we do a vector addition of the agent's current location with the move to determine a resultant location. This is then passed to the LocationService to update the agent's location. If the resultant location is not in the simulation Area we ask the area for a valid version of the move and apply that instead. In the case of a CellMove we simply check the destination cell, and if it's empty we set the new location through the LocationService. Otherwise we throw an ActionHandlingException.

Parameters
action action to handle
actor actor performing this action
Returns
  • May return a further Object to be returned to the actor, or null if not.
Throws
ActionHandlingException
