介绍 (Introduction)

Move3D类在x，y和z维度上移动目标对象。 Move3D效果的x，y和z属性规范指定了变换中心应发生的x，y和z的变化，围绕变换中心发生整体变换效果。

Class 声明 (Class Declaration)

以下是spark.effects.Move3D类的声明 -

public class Move3D
   extends AnimateTransform3D

公共属性 (Public Properties)

S.No	财产和描述
1	xBy : Number 修改目标x位置的像素数。
2	xFrom : Number 目标的初始x位置，以像素为单位。
3	xTo : Number 最终x，以像素为单位。
4	yBy : Number 修改目标y位置的像素数。
5	yFrom : Number 目标的初始y位置，以像素为单位。
6	yTo : Number 目标的最终y位置，以像素为单位。
7	zBy : Number 修改目标z位置的像素数。
8	zFrom : Number 目标的初始z位置。
9	zTo : Number 目标的最终z位置。

公共方法 (Public Methods)

S.No	方法和描述
1	Move3D(target:Object = null) 构造函数。

方法继承 (Methods Inherited)

该类继承以下类中的方法 -

spark.effects.AnimateTransform3D
spark.effects.AnimateTransform
spark.effects.Animate
mx.effects.Effect
flash.events.EventDispatcher

Flex Move3D效果示例

让我们按照以下步骤通过创建测试应用程序来检查Flex应用程序中Move3D Effect的使用情况 -

步	描述
1	在cn.xnip.client包下创建一个名为HelloWorld的项目，如Flex - Create Application一章中所述。
2	修改HelloWorld.mxml ，如下所述。保持其余文件不变。
3	编译并运行应用程序以确保业务逻辑按照要求运行。

以下是修改后的mxml文件src/cn.xnip/HelloWorld.mxml 。

<?xml version = "1.0" encoding = "utf-8"?>
<s:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"
   xmlns:s = "library://ns.adobe.com/flex/spark"

   width = "100%" height = "100%" minWidth = "500" minHeight = "500">
   <fx:Style source = "/com/xnip/client/Style.css" />
   <fx:Script>
      <![CDATA[
         private function applyMoveProperties():void {
            moveEffect.play();
         }
      ]]>
   </fx:Script>
   <fx:Declarations>
      <s:Move3D id = "moveEffect" target = "{imageFlex}"
         xFrom = "{imageFlex.x}" xBy = "{Number(moveX.text)}"
         yFrom = "{imageFlex.y}" yBy = "{Number(moveY.text)}"
         zFrom = "{imageFlex.z}" zBy = "{Number(moveZ.text)}" />
   </fx:Declarations>
   <s:BorderContainer width = "630" height = "480" id = "mainContainer"
      styleName = "container">
      <s:VGroup width = "100%" height = "100%" gap = "50"

               <s:HorizontalLayout  gap = "10" verticalAlign = "middle"
                  horizontalAlign = "center" />
            </s:layout>
            <s:VGroup top = "10" left = "15">

                  <s:Label text = "Move By X:" width = "70" />
                  <s:TextInput id = "moveX" text = "50" width = "50" />
               </s:HGroup>
               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Move By Y:" width = "70" />
                  <s:TextInput id = "moveY" text = "50" width = "50" />
               </s:HGroup>
               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Move By Z:" width = "70" />
                  <s:TextInput id = "moveZ" text = "50" width = "50" />
               </s:HGroup>
               <s:Button label = "Apply Properties" click = "applyMoveProperties()" />
            </s:VGroup>
            <s:Image id = "imageFlex"
               source = "https://www.xnip.cn/images/flex-mini.png" />
         </s:Panel>
      </s:VGroup>
   </s:BorderContainer>
</s:Application>

一旦准备好完成所有更改，让我们像在Flex - Create Application章节中那样在正常模式下编译和运行应用程序。
