在文檔類中填充數組

Question

首先，我完全不熟悉Flash，對我來說很裸露。我在過去做過一些編碼，並且有能力閱讀和理解代碼，但是從頭開始編寫代碼會導致一些問題。

基本上我想要做的就是做出一個測驗與4個按鈕的多選答案。選擇答案後，它會播放一個簡短的動畫並將您帶到下一個問題。我一直在做所有的時間線代碼，但已經知道AS3更適合使用類文件的OOP，所以我現在正在嘗試。

我認爲，而不是讓每個問題1幀我會做所有的問題1幀，並填充問題標題和數組的答案按鈕。我最初在「Action Script」層中定義了數組，但現在我決定在一個名爲DocumentClass.as的類文件中完成它。我未完成的代碼到目前爲止是這樣的：

package { 
import flash.display.MovieClip; 


public class DocumentClass extends MovieClip 
{ 
//global definitions 
private var milanquestions:Array = new Array(); 
private var milancorrectanswers:Array = new Array(); 
private var userscore:Number = 0; 
private var currentquestion:Number = 0; 

milanquestions[0] = "What is the primary type of Rescue used?"; 
milanquestions[1] = "Why is Remote Lower the preffered method to use?"; 
milanquestions[2] = "Which pieces of equipment are needed to complete a Rescue safely?"; 
milanquestions[3] = "Who conducts the Rescue?"; 
milanquestions[4] = "Once the casualty reaches the ground, what is it important to do first?"; 
milanquestions[5] = "What is used to keep the casualty clear of any obstruction?"; 

milancorrectanswers[0] = "Remote Lower"; 
milancorrectanswers[1] = "It can be done without another operative needing to climb down to the casualty"; 
milancorrectanswers[3] = "A Balfour Beatty operative trained in Tower Rescue"; 
milancorrectanswers[4] = "Place in the recovery position and administer first aid where possible"; 
milancorrectanswers[5] = "A holding out rope"; 

public function DocumentClass() 
    { 
     //a place for listeners 
    } 
    } 
} 

使用此代碼我得到的每個條目下面的錯誤到數組：

P:\Interactive Animation test folder\DocumentClass.as, Line 13 1120: Access of undefined property milanquestions. 
P:\Interactive Animation test folder\DocumentClass.as, Line 14 1120: Access of undefined property milanquestions. 

等

我想填充有問題和正確答案的陣列，但我似乎無法解決這些錯誤。有任何想法嗎？或者有關更好的方法來做我想做的事情的任何建議？

    //global definitions 
    private var milanquestions:Array = new Array(); 
    private var milancorrectanswers:Array = new Array(); 
    private var userscore:Number = 0; 
    private var currentquestion:Number = 0; 

    public function DocumentClass() 
    { 
    //a place for listeners 
     initAnswerAndQuestions(); 
    } 

    private function initAnswerAndQuestions():void { 

     milanquestions[0] = "What is the primary type of Rescue used?"; 
     milanquestions[1] = "Why is Remote Lower the preffered method to use?"; 
     milanquestions[2] = "Which pieces of equipment are needed to complete a Rescue safely?"; 
     milanquestions[3] = "Who conducts the Rescue?"; 
     milanquestions[4] = "Once the casualty reaches the ground, what is it important to do first?"; 
     milanquestions[5] = "What is used to keep the casualty clear of any obstruction?"; 


     milancorrectanswers[0] = "Remote Lower"; 

     milancorrectanswers[1] = "It can be done without another operative needing to climb down to the casualty";
