介绍 (Introduction)

Rotate3D类围绕x，y或z轴以三维方式旋转目标对象。旋转发生在目标的变换中心周围。

Class 声明 (Class Declaration)

以下是spark.effects.Rotate3D类的声明 -

public class Rotate3D
   extends AnimateTransform3D

公共属性 (Public Properties)

S.No	财产和描述
1	angleXFrom : Number 目标对象围绕x轴的起始旋转角度，以度表示。
2	angleXTo : Number 目标对象围绕x轴的旋转结束角度，以度表示。
3	angleYFrom : Number 目标物体围绕y轴的起始旋转角度，以度表示。
4	angleYTo : Number 目标对象围绕y轴的旋转结束角度，以度表示。
5	angleZFrom : Number 目标对象围绕z轴的起始旋转角度，以度表示。
6	angleZTo : Number 目标对象围绕z轴的旋转结束角度，以度表示。

公共方法 (Public Methods)

S.No	方法和描述
1	Rotate3D(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

Flex Rotate3D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Rotate3D 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 。

               </s:HGroup>
               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Rotate By Y:" width = "70" />
                  <s:TextInput id = "rotateY" text = "15.0" width = "50" />
               </s:HGroup>
               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Rotate By Z:" width = "70" />
                  <s:TextInput id = "rotateZ" text = "15.0" width = "50" />
               </s:HGroup>
               <s:Button label = "Apply Properties"
                  click = "applyRotateProperties()" />
            </s:VGroup>
            <s:Image id = "imageFlex"
               source = "https://www.xnip.cn/images/flex-mini.png"
               height = "200" width = "200" />
         </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。
