Flex - 三维旋转效果

介绍

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

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，通过创建一个测试应用程序来检查在 Flex 应用程序中使用 Rotate3D 效果：

步骤	描述
1	创建一个名为 HelloWorld 的项目，其包名为 com.tutorialspoint.client，详见 Flex - 创建应用章节。
2	修改 HelloWorld.mxml 文件，如下所示。其余文件保持不变。
3	编译并运行应用程序，以确保业务逻辑按要求工作。

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

<?xml version = "1.0" encoding = "utf-8"?>

         private function applyRotateProperties():void {
            rotateEffect.play();
         }
      ]]>

               <s:HGroup verticalAlign = "middle">
                  <s:Label text = "Rotate By X:" width = "70" />
                  <s:TextInput id = "rotateX" text = "45.0" width = "50" />
               </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://tutorialspoint.com/images/flex-mini.png"
               height = "200" width = "200" />
         </s:Panel>
      </s:VGroup>
   </s:BorderContainer>
</s:Application>

完成所有更改后，让我们像在Flex - 创建应用章节中一样，以正常模式编译并运行应用程序。如果应用程序一切正常，则会产生以下结果：[在线试用]
