lib-flex-animation-code-10-org-as3lib-kitchensync-action-KSStepedSequenceGroup.ax (swf ) [ flash ] flex


  package org.as3lib.kitchensync.action
  {
          import flash.utils.getQualifiedClassName;
          
          import org.as3lib.kitchensync.core.KitchenSyncEvent;

A sequence that plays each child then pauses until it is started again. Perfect for slideshow or powerpoint-like applications. @uthor Mims Wright @since 1.6


  
          public class @ax-lib-flex-animation-code-10-org-as3lib-kitchensync-action-KSStepedSequenceGroup extends KSSequenceGroup
          {

Used internally to determine whether the next item should play or whether the children should simply be unpaused when the unpause() method is called.


  
                  protected var _waitingForInput:Boolean = false;

Constructor. Identical to KSSequenceGroup.
parameter: children Optional children to add upon instantiation.


  
                  public function @ax-lib-flex-animation-code-10-org-as3lib-kitchensync-action-KSStepedSequenceGroup(...children)
                  {
                          super();
                          for (var i:int = 0; i < children.length; i++) {
                                  if (children[i] is IAction) {
                                          var action:IAction = IAction(children[i]);
                                          addAction(action); 
                                  } else {
                                          throw new TypeError ("All children must be of type IAction. Make sure you are not calling start() on the objects you've added to the group. Found " + getQualifiedClassName(children[i]) + " where IAction was expected.");
                                  }
                          }
                  }

Override the onChildFinished handler to pause the sequence after each child completes.


  
                  override protected function onChildFinished(event:KitchenSyncEvent):void {
                          //super.onChildFinished(event);
                          _currentAction.removeEventListener(KitchenSyncEvent.COMPLETE, onChildFinished);
                          _currentAction.removeEventListener(KitchenSyncEvent.START, onChildStart);
                          //_currentAction = null;
                          if (!checkForComplete()) {
                                  _waitingForInput = true;
                                  pause();
                          } else {
                                  complete();
                          }
                  }

Override unpause to see if the sequence was paused internally or externally.


  
                  override public function unpause():void {
                          super.unpause();
                          if (_waitingForInput) {
                                  _waitingForInput = false;
                                  // Start the next action only if unpause() is called after the group was paused internally.
                                  startNextAction();
                          }
                  }
          }
  }
