在SWFLoader上的Actionscript 3和Flex 4 Zoom Gesture

Question

我似乎在SWFLoader上遇到了Zoom Gestures的问题.我有一个swf文件,这是一个家庭的平面图,我希望用户能够用两个手指触摸放大和缩小,下面的代码是我尝试过但不起作用.当我在触摸屏上进行测试时,当我将两根手指放在SWF中并尝试放大时,它不会缩放.

<s:SWFLoader id="floorplanImage" source="@Embed('assets/test2.swf')" width="100%" height="100%" smoothBitmapContent="true" horizontalAlign="center" />

这是我的动作3代码

import flash.ui.Multitouch;  
            import flash.ui.MultitouchInputMode;  

            Multitouch.inputMode = MultitouchInputMode.GESTURE;

            import flash.events.Event;

            public var selectedItem:Object;

            public function init(): void
            {
                floorplanImage.addEventListener(TransformGestureEvent.GESTURE_ZOOM , onZoom);
            }

            public function onZoom (e:TransformGestureEvent):void{
                floorplanImage.scaleX *= e.scaleX;
                floorplanImage.scaleY *= e.scaleY; 
            }

请帮忙!

UPDATE

我正在使用gestouch的路线,但是使用此代码,我无法放大或缩小SWF.使用常规图像可以正常工作,但除非我遗漏了某些东西,否则不能使用SWF.这是我的代码:

<mx:Script>
                <![CDATA[

                    import org.gestouch.events.GestureEvent;
                    import org.gestouch.gestures.TransformGesture;

                    private var _zoom:TransformGesture;

                    [Embed(source="assets/test2.swf")]
                    private var myClass:Class;
                    private var myMovieClip:MovieClip;


                    private function initModel():void
                    {   

                        myMovieClip = MovieClip(new myClass());
                        swfcontainer.addChild(myMovieClip);

                        _zoom = new TransformGesture(swfcontainer);
                        _zoom.addEventListener(org.gestouch.events.GestureEvent.GESTURE_BEGAN, onGesture);
                        _zoom.addEventListener(org.gestouch.events.GestureEvent.GESTURE_CHANGED, onGesture);

                    }

                    private function onGesture(event:org.gestouch.events.GestureEvent):void
                    {
                        const gesture:TransformGesture = event.target as TransformGesture;
                        var matrix:Matrix = swfcontainer.transform.matrix;

                        // Panning
                        matrix.translate(gesture.offsetX, gesture.offsetY);
                        swfcontainer.transform.matrix = matrix;

                        if (gesture.scale != 1)
                        {
                            // Scale and rotation.
                            var transformPoint:Point = matrix.transformPoint(swfcontainer.globalToLocal(gesture.location));
                            matrix.translate(-transformPoint.x, -transformPoint.y);
                            matrix.scale(gesture.scale, gesture.scale);
                            matrix.translate(transformPoint.x, transformPoint.y);

                            swfcontainer.transform.matrix = matrix;
                        }
                    }

                ]]>
            </mx:Script>

<mx:Image id="swfcontainer" horizontalAlign="center" width="100%" height="100%" />

当我使用常规图像时,它仍然无法正常工作...它不会让图像在缩放时保持中心,它不会让我放大,只有当我第一次使用它时,它会移动图像在右边.怎么这么难过？

请记住,我对Adobe Flex和Actionscript非常新,所以请尽可能清楚地回答.

Answer 1

你的代码没有问题,我会解释我为我的项目做了什么.也许它有所帮助,我有Window设计应用程序,我加载SWF到starling,并有缩放和泛问题;

仅供参考:我使用starling并在starling和zoom pan工作中加载带有原生叠加的SWF文件

   _mLoader = new Loader();
 var mRequest:URLRequest = new URLRequest("drawer.swf" + "?nf=" + getTimer());
_mLoader.contentLoaderInfo.addEventListener(flash.events.Event.COMPLETE, onCompleteHandler);
 _mLoader.load(mRequest);


     private function onCompleteHandler(loadEvent:flash.events.Event):void
    {
          _mLoader.contentLoaderInfo.removeEventListener(flash.events.Event.COMPLETE, 
           Starling.current.nativeOverlay.addChild(LoaderInfo(loadEvent.currentTarget).content);

    }

并且因为触摸闪光灯的库很弱,我使用上面的lib,这是强

首先测试上面的lib可能是没有Starling的工作

比flash lib更好的GESTURE lib

我的缩放代码与这个库

     var _zoom:
    _zoom = new TransformGesture(this);
    _zoom.addEventListener(GestureEvent.GESTURE_BEGAN, onGesture);
    _zoom.addEventListener(GestureEvent.GESTURE_CHANGED, onGesture);

private function onGesture(event:org.gestouch.events.GestureEvent):void 
    {

        const gesture:TransformGesture = event.target as TransformGesture;

        var matrix:Matrix = container_movieclip.transform.matrix;



        if (container_movieclip.scaleX!=1 || container_movieclip.scaleY!=1) 
        {
            matrix.translate(gesture.offsetX, gesture.offsetY);
            container_movieclip.transform.matrix = matrix;
        }

        if (gesture.scale != 1)
        {
            var transformPoint:Point = matrix.transformPoint(container_movieclip.globalToLocal(gesture.location));
            matrix.translate(-transformPoint.x, -transformPoint.y);
            matrix.scale(gesture.scale, gesture.scale);
            matrix.translate(transformPoint.x, transformPoint.y);
            container_movieclip.transform.matrix = matrix;

        }

    }

我希望我能帮忙
