    java.io.Serializable, java.lang.Comparable<Event>

    public class CustomEvent

      • CustomEvent

        public CustomEvent​(Condition condition)
        Called by the game to create a new CustomEvent when a condition is met.
        Parameters:
        condition - the condition that must be met
      • CustomEvent

        public CustomEvent​(Condition condition,
                           int priority)
        Called by the game to create a new CustomEvent when a condition is met. The event will have the given priority. An event priority is a value from 0 - 99. The higher value, the higher priority. The default priority is 80.

        This is equivalent to calling Condition.setPriority(int) on the Condition.

        Parameters:
        condition - the condition that must be met
        priority - the priority of the condition

      • getCondition

        public Condition getCondition()
        Returns the condition that fired, causing this event to be generated. Use this to determine which condition fired, and to remove the custom event.
           public void onCustomEvent(CustomEvent event) {
               if (event.getCondition().getName().equals("mycondition")) {
                   removeCustomEvent(event.getCondition());
                   // do something else
               }
           }
         
        Returns:
        the condition that fired, causing this event to be generated
      • compareTo

        public final int compareTo​(Event event)
        Compares this event to another event regarding precedence. The event precedence is first and foremost determined by the event time, secondly the event priority, and lastly specific event information.

        This method will first compare the time of each event. If the event time is the same for both events, then this method compared the priority of each event. If the event priorities are equals, then this method will compare the two event based on specific event information.

        This method is called by the game in order to sort the event queue of a robot to make sure the events are listed in chronological order.

        Specified by:
        compareTo in interface java.lang.Comparable<Event>
        Overrides:
        compareTo in class Event
        Parameters:
        event - the event to compare to this event.
        Returns:
        a negative value if this event has higher precedence, i.e. must be listed before the specified event. A positive value if this event has a lower precedence, i.e. must be listed after the specified event. 0 means that the precedence of the two events are equal.
      • getPriority

        public final int getPriority()
        Returns the priority of this event.

        An event priority is a value from 0 - 99. The higher value, the higher priority.

        The default priority is 80, but varies depending on the type of event.

        Overrides:
        getPriority in class Event
        Returns:
        the priority of this event.
