Flex - Rotate3D 效果

简介

Rotate3D 类围绕 x、y 或 z 轴在三维空间中旋转目标对象。旋转围绕目标的变换中心进行。

类声明

以下是 spark.effects.Rotate3D 类的声明 −

public class Rotate3D
   extends AnimateTransform3D

Flex Rotate3D 效果示例

让我们按照以下步骤检查通过创建测试应用程序在 Flex 应用程序中实现 Rotate3D 效果 −

步骤	说明
1	按照 Flex - 创建应用程序一章中的说明，在 com.tutorialspoint.client 包下创建一个名为 HelloWorld 的项目。
2	按照下面的说明修改 HelloWorld.mxml。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要求运行。

以下是修改后的 mxml 文件 src/com.tutorialspoint/HelloWorld.mxml 的内容。
