Question

首先，我对Flash非常陌生，所以我很开心。我过去做过一些编码，有能力阅读和理解代码，但是从头开始写代码会引起一些问题。

基本上我要做的就是用4个按钮进行测验以获得多项选择答案。选择答案后，它会播放一个简短的动画并带您进入下一个问题。我正在使用时间线代码完成所有这些但是已经学习了，因为AS3更适合使用类文件的OOP，所以我现在正在尝试。

我认为而不是每个问题制作1帧我将为所有问题制作1帧并填充问题标题和数组中的答案按钮。我最初在“Action Script”层中定义了数组，但现在我决定在名为DocumentClass.as的类文件中执行此操作。到目前为止，我未完成的代码是：

    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
    }
  }
}

使用此代码我在数组的每个条目中收到以下错误：

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

我希望用问题和正确的答案填充数组，但我似乎无法解决这些错误。有任何想法吗？或者有关更好地做我想做的事情的任何建议？

Answer 1

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;

    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";
        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";
    }
}

填充文档类中的数组
