Я очень-очень новичок в разработке ActionScript 3.0 для Blackberry Playbook.
Я работаю с двусторонним 3D Plane в FP10, и у меня возникли проблемы с этим кодом:
package
{
import flash.display.Sprite;
import flash.events.Event;
public class FlipCard extends Sprite
{
private var myPaperSprite:PaperSprite;
public function FlipCard()
{
super();
}
private function Flip():void
{
/*
Create a new PaperSprite:
If your front and back faces already exist, you can pass them straight
into the constructor, like so:
myPaperSprite = new PaperSprite( myFrontMc, myBackMc );
*/
myPaperSprite = new PaperSprite();
/*
Optionally specify a pivot point, in this example the centre is used
(this is also the default so there is no need to set this normally).
To pivot around the top left use:
myPaperSprite.pivot = new Point(0,0);
or for bottom right:
myPaperSprite.pivot = new Point(1,1);
and so on...
*/
myPaperSprite.pivot = new Point(0.5,0.5);
строка myPaperSprite.pivot = new Point(0.5,0.5); выдает следующую ошибку:
1180: Call to a possibly undefined method Point.
И поворотный элемент определяется следующим образом:
package
{
import flash.display.DisplayObject;
import flash.display.Sprite;
import flash.events.Event;
import flash.geom.Point;
import flash.geom.Rectangle;
public class PaperSprite extends Sprite
{
//___________________________________________________________
//————————————————————————————————————————————— CLASS MEMBERS
private static const POINT_A:Point = new Point(0, 0);
private static const POINT_B:Point = new Point(100, 0);
private static const POINT_C:Point = new Point(0, 100);
private var _isFrontFacing:Boolean = true;
private var _autoUpdate:Boolean = true;
private var _pivot:Point = new Point(0.5,0.5);
private var _front:DisplayObject;
private var _back:DisplayObject;
private var _p1:Point;
private var _p2:Point;
private var _p3:Point;
//___________________________________________________________

/**
* A Point Object used to determine the pivot, or registration point of the
* PaperSprite. The values should be between 0 and 1 and are relative to the
* dimensions of each face, 0 being far left (on the x axis) or top (y axis)
* and 1 being the far right (x axis) or bottom (y axis).
*
* The default value is { x:0.5, y:0.5 } meaning that both faces will pivot
* around their respective centres
*
* Examples:
*
* To pivot from the centre use: new Point( 0.5, 0.5 );
* To pivot from the top left use: new Point( 0.0, 0.0 );
* To Pivot from the bottom right use: new Point( 1.0, 1.0 );
*
*/
public function get pivot():Point
{
return _pivot;
}
public function set pivot( value:Point ):void
{
_pivot = value;
alignFaces();
}
В чем проблема? Что я делаю неправильно?
