錯誤1120訪問未定義的屬性

Question

我是新來的操作腳本3，我不斷收到兩個1120錯誤。一個錯誤的是

C:\Users\Server\Desktop\New folder\InteractiveStoryBook\Main.as, Line 31 1120: Access of undefined property onFrogMouseOver 

和其他錯誤是

C:\Users\Server\Desktop\New folder\InteractiveStoryBook\Main.as, Line 32 1120: Access of undefined property onFrogClick. 

我正確添加我的所有情況，但我仍然得到錯誤。 這是在該地區的代碼中的錯誤是：

之前

public function Main()

     hillPage = new HillPage(); 
     pondPage = new PondPage();

} 

一切都只是變量和擴展影片剪輯和所有其他的東西。謝謝！

您的方法onFrogMouseOver和onFrogClick嵌套在onRightButtonClick內。

將他們趕出onRightButtonClick塊：

function onRightButtonClick(event:MouseEvent):void 
{ 
    if(hillPage.cat.x <= 487) 
    { 
     hillPage.cat.x += 15; 
    } 

    // They were previously defined here. 
    // Removed and put below. 
} 

function onFrogMouseOver(event:MouseEvent):void 
{ 
    pondPage.frog.goToAndStop(2); 
    pondPage.frog.removeEventListener(MouseEvent.MOUSE_OVER, onFrogMouseOver); 
} 

function onFrogClick(event:MouseEvent):void 
{ 
    pondPage.frog.goToAndStop(3); 
    pondPage.frog.removeEventListener(MouseEvent.CLICK, onFrogClick); 
}
