Class ActionQueue

java.lang.Object
  nl.tudelft.goal.ut2004.actions.ActionQueue

public final class ActionQueue
extends Object

Smart queue for actions. There is a limited bandwidth to transfer actions between GOAL and the UT2004Bot. GOAL will send actions at a high rate and could saturate the queue. To prevent this we check which actions are in the queue before adding a new action. There are three possible scenarios:

• If the effects of a new action would cancel out the effects of an action in the queue, the queued action is discarded.
• If the effects of a new action have no effect on an action in the queue, the action is put in.
• If an action in the queue means the new action has no effect, the new action id discarded.
