動作的孩子中3的addChild並清除第一個孩子

Question

好了，所以這裏是設置：

在主時間軸我有一個菜單，這是一個MovieClip。該菜單由大約17個「按鈕」組成，每個按鈕指向站點的不同部分。點擊一個「按鈕」（2個示例：menu_bag_button，menu_trashbag_button），菜單將動畫，向左移動，並且2個庫項目（bag_container和close_btn）應顯示在「framecontainer」的右側。

然後，當菜單在左邊時，這個特定的按鈕不能重複菜單動畫，因此我做了一個if語句來查找它所在的框架，如果它在左邊，它只是清除framecontainer和再次加載內容。

問題是，當單擊另一個鏈接時，它需要執行以下兩件事之一：如果菜單位於未加載內容的中央，則需要將菜單右側設置爲動畫，並將內容/ close_btn放入「framecontainer」;或者，如果菜單位於左側，則需要清除「framecontainer」並加載相應的內容。我嘗試了很多東西，但由於所有這些按鈕都在「menu_mc」中，動作必須指向根，然後才能指向「framecontainer」，一切都會變得複雜。

如果有一個快速，更好的方法來做到這一點，而不需要我編碼幾個小時，那將是非常棒的，否則我現在必須堅持這種複雜的方式。

這是我目前的代碼。它的功能很好，除了它不明確內容的事實，所以它繼續讓一個被關閉加載框架，還有它背後的其它內容：

import flash.display.*; 
import fl.transitions.*; 
import flash.events.MouseEvent; 

//Stopping on this frame (805) so the menu will be in place to interact with 
stop(); 

//framecontainer location/size for the content to be loaded. 
//Not sure if the parameters below it are absolutely necessary. 
var framecontainer:MovieClip = new MovieClip(); 
framecontainer.width = 450; 
framecontainer.height = 450; 
framecontainer.x = 450; 
framecontainer.y = 0; 

//adding the framecontainer so that the content can be loaded into it. 
//again, not sure if this is necessary yet 
MovieClip(root).addChild(framecontainer); 




//FIRST MENU ITEM, "BAG" 
//If we can get the framecontainer to work, I don't think I'll have to create 
//a custom closeBtn for each and every link. I'll be able to just use a generic 
//closeBtn and have it clear the framecontainer and continue the animation. 

var closebagBtn:close_btn = new close_btn(); 
closebagBtn.x = 0; 
closebagBtn.y = 0; 

var bagFrame:MovieClip = new bag_frame_mc();

function bagClick(event:MouseEvent):void{ 
    if(MovieClip(root).currentFrame == 850) { 
// the next line does nothing, but it's supposed to clear 
MovieClip(root).framecontainer.clear(); 
} 
//Below, I need to add bagFrame and closebagBtn into framecontainer, 
//but I don't know how. Tried adding ".framecontainer" in front of addchild 
//but got error saying that bagClick (function above) is undefined.

//but I don't know how. Tried adding ".framecontainer" in front of addchild

Answer 1

首先，我真的希望這不是「時間線」的代碼！我希望這個代碼在課堂上。

其次，我真的不喜歡使用「root」的想法。如果你打算不止一次地使用它，你可以爲它創建一個新的變量，輸入爲動畫片段，並引用它，而不是總是將它轉換爲動畫片段。例如

var target:MovieClip = root as MovieClip; 
target.addChild(container); 

如果這個代碼是在主時間軸上，那麼你甚至不需要引用根（但它似乎並不像它）。

要回答你的問題實際...

沒有與這些行一個問題：

MovieClip(root).addchild (container); 
MovieClip(root).container.addChild (bagLink); 
MovieClip(root).addChild (closeBtn); 
MovieClip(root).gotoAndPlay(806); 

的問題是，當你說影片剪輯（根）.addchild（容器）;，您正在將容器變量的「內容」添加爲根的子項。 var容器的內容並不知道你稱之爲「容器」，所以你不能說MovieClip（root）.container。

但是你可以說：

container.addChild(bagLink); 

由於VAR容器指向容器影片剪輯。
