Flex - 三維旋轉效果

介紹

Rotate3D 類圍繞 x、y 或 z 軸在三維空間中旋轉目標物件。旋轉圍繞目標物件的變換中心進行。

類宣告

以下是 **spark.effects.Rotate3D** 類的宣告：

public class Rotate3D
   extends AnimateTransform3D

公共屬性

序號	屬性和描述
1	angleXFrom : Number 目標物件圍繞 x 軸旋轉的起始角度（以度為單位）。
2	angleXTo : Number 目標物件圍繞 x 軸旋轉的結束角度（以度為單位）。
3	angleYFrom : Number 目標物件圍繞 y 軸旋轉的起始角度（以度為單位）。
4	angleYTo : Number 目標物件圍繞 y 軸旋轉的結束角度（以度為單位）。
5	angleZFrom : Number 目標物件圍繞 z 軸旋轉的起始角度（以度為單位）。
6	angleZTo : Number 目標物件圍繞 z 軸旋轉的結束角度（以度為單位）。

Flex Rotate3D 效果示例

讓我們按照以下步驟，透過建立一個測試應用程式來檢查在 Flex 應用程式中使用 Rotate3D 效果：

步驟	描述
1	建立一個名為 HelloWorld 的專案，其包名為 com.tutorialspoint.client，詳見 Flex - 建立應用章節。
2	修改 HelloWorld.mxml 檔案，如下所示。其餘檔案保持不變。
3	編譯並執行應用程式，以確保業務邏輯按要求工作。

以下是修改後的 mxml 檔案 **src/com.tutorialspoint/HelloWorld.mxml** 的內容。

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

            rotateEffect.play();
         }
      ]]>

            fontSize = "40" color = "0x777777" styleName = "heading" />
            
         <s:Panel id = "rotate3DPanel" title = "Using Rotate3D Effect"

            </s:layout>

               <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.tw/images/flex-mini.png"
               height = "200" width = "200" />
         </s:Panel>
      </s:VGroup>
   </s:BorderContainer>
</s:Application>

完成所有更改後，讓我們像在Flex - 建立應用章節中一樣，以正常模式編譯並執行應用程式。如果應用程式一切正常，則會產生以下結果：[線上試用]
