 </s:Group>


protected function swe_clickHandler(event:MouseEvent):void

}

我的qustion是 我怎样才能使单击点泛成箱的中心？ 请帮助。

推荐答案

这应该做的伎俩：

<fx:Declarations>
    <s:Move id="moveEffect" />
</fx:Declarations>

<s:Group id="mapContainer" width="300" height="300" clipAndEnableScrolling="true"
         click="pan(event.localX, event.localY)">

    <s:Image id="map" source="@Embed('bigMap.png')" />
</s:Group>

localX'和'localY'是鼠标的'x'和'y'的位置相对于mapContainer

'localX' and 'localY' are the mouse's 'x' and 'y' position relative to the mapContainer.

而现在的锅（）方法：

private function pan(mouseX:Number, mouseY:Number):void {
    //calculate the offset from mapContainer's center
    var diffX:Number = mapContainer.width/2 - mouseX;
    var diffY:Number = mapContainer.height/2 - mouseY;

    //move the map through the move effect
    moveEffect.xFrom = map.x;
    moveEffect.yFrom = map.y;
    moveEffect.xTo = diffX;
    moveEffect.yTo = diffY;

    moveEffect.play([map]);
}
